INFORMATION
GENERAL DESCRIPTION (PDL129)
The Am29PDL129H is a 128 Mbit, 3.0 volt-only Page Mode and Simultaneous Read/Write Flash memory device organized as 8 Mwords. The word-wide data (x16) appears on DQ15-DQ0. This device can be programmed in-system or in standard EPROM programmers. A 12.0 V VPP is not required for write or erase operations. The device offers fast page access time of 25 and 30 ns, with corresponding random access times of 65 and 85 ns, respectively, allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#f1, CE#f2), write enable (WE#) and output enable (OE#) controls. Dual Chip Enables allow access to two 64 Mbit partitions of the 128 Mbit memory space. The device is entirely command set compatible with the JEDEC 42.4 single-power-supply Flash standard. Commands are written to the command register using standard microprocessor write timing. Register contents serve as inputs to an internal state-machine that controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices. Device programming occurs by executing the program command sequence. The Unlock Bypass mode facilitates faster programming times by requiring only two write cycles to program data instead of four. Device erasure occurs by executing the erase command sequence. The host system can detect whether a program or erase operation is complete by reading the DQ7 (Data# Polling) and DQ6 (toggle) status bits. After a program or erase cycle has been completed, the device is ready to read array data or accept another command. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory. Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of sectors of memory. This can be achieved in-system or via programming equipment. The Erase Suspend/Erase Resume feature enables the user to put erase on hold for any period of time to read data from, or program data to, any sector that is not selected for erasure. True background erase can thus be achieved. If a read is needed from the SecSi Sector area (One Time Program area) after an erase suspend, then the user must use the proper command sequence to enter and exit this region. The device offers two power-saving features. When addresses have been stable for a specified amount of time, the device enters the automatic sleep mode. The system can also place the device into the standby mode. Power consumption is greatly reduced in both these modes. AMD's Flash technology combined years of Flash memory manufacturing experience to produce the highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a sector simultaneously via Fowler-Nordheim tunneling. The data is programmed using hot electron injection.
Simultaneous Read/Write Operation with Zero Latency
The Simultaneous Read/Write architecture provides simultaneous operation by dividing the memory space into 4 banks, which can be considered to be four separate memory arrays as far as certain operations are concerned. The device can improve overall system performance by allowing a host system to program or erase in one bank, then immediately and simultaneously read from another bank with zero latency (with two simultaneous operations operating at any one time). This releases the system from waiting for the completion of a program or erase operation, greatly improving system performance. The device can be organized in both top and bottom sector configurations. The banks are organized as follows:
Chip Enable Configuration CE#f1 Control Bank 1A 48 Mbit (32 Kw x 96) Bank 1B 16 Mbit (4 Kw x 8 and 32 Kw x 31) CE#f2 Control Bank 2A 16 Mbit (4 Kw x 8 and 32 Kw x 31) Bank 2B 48 Mbit (32 Kw x 96)
Page Mode Features
The page size is 8 words. After initial page access is accomplished, the page mode operation provides fast read access speed of random locations within that page.
Standard Flash Memory Features
The device requires a single 3.0 volt power supply (2.7 V to 3.3 V) for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations.

INFORMATION page mode accesses are obtained by keeping A22-A3 (A21-A3 for PDL129) constant and changing A2 to A0 to select the specific word within that page.
Requirements for Reading Array Data
To read array data from the outputs, the system must drive the OE# and appropriate CE#f1/CE#f2 (PDL129 only) pins to VIL. CE#f1 and CE#f2 are the power control and for PDL129 select the lower (CE#f1) or upper (CE#f2) halves of the device. OE# is the output control and gates array data to the output pins. WE# should remain at VIH. The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data. Standard microprocessor read cycles that assert valid addresses on the device address inputs produce valid data on the device data outputs. Each bank remains enabled for read access until the command register contents are altered. Refer to the Flash AC Characteristics table for timing specifications and to Figure 12 for the timing diagram. ICC1 in the DC Characteristics table represents the active current specification for reading array data. Random Read (Non-Page Read) Address access time (tACC) is equal to the delay from stable addresses to valid output data. The chip enable access time (t CE ) is the delay from the stable addresses and stable CE#f1 to valid data at the output inputs. The output enable access time is the delay from the falling edge of the OE# to valid data at the output inputs (assuming the addresses have been stable for at least tACC-tOE time). Page Mode Read The device is capable of fast page mode read and is compatible with the page mode Mask ROM read operation. This mode provides faster read access speed for random locations within a page. Address bits A22-A3 (A21-A3 for PDL129) select an 8-word page, and address bits A2-A0 select a specific word within that page. This is an asynchronous operation with the microprocessor supplying the specific word location. The random or initial page access is t ACC or tCE and subsequent page read accesses (as long as the locations specified by the microprocessor fall within that page) are t PACC. When CE#f1 and CE#f2 (PDL129 only) are deasserted (CE#f1=CE#f2=VIH), the reassertion of CE#f1 or CE#f2 (PDL129 only) for subsequent access has access time of tACC or tCE . Here again, CE#f1/CE#f2 (PDL129 only) selects the device and OE# is the output control and should be used to gate data to the output inputs if the device is selected. Fast

Simultaneous Operation
In addition to the conventional features (read, program, erase-suspend read, and erase-suspend program), the device is capable of reading data from one bank of memory while a program or erase operation is in progress in another bank of memory (simultaneous operation), The bank can be selected by bank addresses (A22-A20) (A21-A20 for PDL129) with zero latency.

INFORMATION Autoselect Functions If the system writes the autoselect command sequence, the device enters the autoselect mode. The system can then read autoselect codes from the internal register (which is separate from the memory array) on DQ15-DQ0. Standard read cycle timings apply in this mode. Refer to the Autoselect Command Sequence sections for more information.
Writing Commands/Command Sequences
To write a command or command sequence (which includes programming data to the device and erasing sectors of memory), the system must drive WE# and CE#f1 or CE#f2 (PDL 129 only) to VIL, and OE# to VIH. The device features an Unlock Bypass mode to facilitate faster programming. Once a bank enters the Unlock Bypass mode, only two write cycles are required to program a word, instead of four. The "Word Program Command Sequence" section has details on programming data to the device using both standard and Unlock Bypass command sequences. An erase operation can erase one sector, multiple sectors, or the entire device. Table 4 indicates the address space that each sector occupies. A "bank address" is the address bits required to uniquely select a bank. Similarly, a "sector address" refers to the address bits required to uniquely select a sector. The "Command Definitions" section has details on erasing a sector or the entire chip, or suspending/resuming the erase operation. ICC2 in the DC Characteristics table represents the active current specification for the write mode. The Flash AC Characteristics section contains timing specification tables and timing diagrams for write operations. Accelerated Program Operation The device offers accelerated program operations through the ACC function. This function is primarily intended to allow faster manufacturing throughput at the factory. If the system asserts VHH on this pin, the device automatically enters the aforementioned Unlock Bypass mode, temporarily unprotects any protected sectors, and uses the higher voltage on the pin to reduce the time required for program operations. The system would use a two-cycle program command sequence as required by the Unlock Bypass mode. Removing VHH from the WP#/ACC pin returns the device to normal operation. Note that VHH must not be asserted on WP#/ACC for operations other than accelerated programming, or device damage may result. In addition, the WP#/ACC pin should be raised to VCC when not in use. That is, the WP#/ACC pin should not be left floating or unconnected; inconsistent behavior of the device may result.
Standby Mode
When the system is not reading or writing to the device, it can place the device in the standby mode. In this mode, current consumption is greatly reduced, and the outputs are placed in the high impedance state, independent of the OE# input. The device enters the CMOS standby mode when the CE#f1, CE#f2 (PDL129 only) and RESET# pins are all held at VIO 0.3 V. (Note that this is a more restricted voltage range than VIH .) If CE#f1, CE#f2 (PDL129 only), and RESET# are held at VIH, but not within VCC 0.3 V, the device will be in the standby mode, but the standby current will be greater. The device requires standard access time (tCE) for read access when the device is in either of these standby modes, before it is ready to read data. If the device is deselected during erasure or programming, the device draws active current until the operation is completed. ICC3 in the DC Characteristics table represents the CMOS standby current specification.
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when addresses remain stable for tACC + 150 ns. The automatic sleep mode is independent of the CE#f1/CE#f2 (PDL129 only), WE#, and OE# control signals. Standard address access timings provide new data when addresses are changed. While in sleep mode, output data is latched and always available to the system. Note that during automatic sleep mode, OE# must be at VIH before the device reduces current to the stated sleep mode specification. ICC5 in the DC Characteristics table represents the automatic sleep mode current specification.

INFORMATION internal reset operation is complete, which requires a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/BY# to determine whether the reset operation is complete. If RESET# is asserted when a program or erase operation is not executing (RY/BY# pin is "1"), the reset operation is completed within a time of tREADY (not during Embedded Algorithms). The system can read data tRH after the RESET# pin returns to VIH. Refer to the pSRAM AC Characteristics tables for RESET# parameters and to Figure 11 for the timing diagram.
RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates all output pins, and ignores all read/write commands for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data integrity. Current is reduced for the duration of the RESET# pulse. When RESET# is held at VSS0.3 V, the device draws CMOS standby current (ICC4). If RESET# is held at VIL but not within VSS0.3 V, the standby current will be greater. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the Flash memory, enabling the system to read the boot-up firmware from the Flash memory. If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a "0" (busy) until the
Output Disable Mode
When the OE# input is at VIH, output from the device is disabled. The output pins (except for RY/BY#) are placed in the highest Impedance state Table 5.

SECTOR PROTECTION
The Am29PDL127H/Am29PDL129H features several levels of sector protection, which can disable both the program and erase operations in certain sectors or sector groups: Dynamically Locked--The sector is protected and can be changed by a simple command. Unlocked--The sector is unprotected and can be changed by a simple command. To achieve these states, three types of "bits" are used: Persistent Protection Bit (PPB) A single Persistent (non-volatile) Protection Bit is assigned to a maximum four sectors (see the sector address tables for specific sector protection groupings). All 4 Kword boot-block sectors have individual sector Persistent Protection Bits (PPBs) for greater flexibility. Each PPB is individually modifiable through the PPB Write Command. The device erases all PPBs in parallel. If any PPB requires erasure, the device must be instructed to preprogram all of the sector PPBs prior to PPB erasure. Otherwise, a previously erased sector PPBs can potentially be over-erased. The flash device does not have a built-in means of preventing sector PPBs over-erasure. Persistent Protection Bit Lock (PPB Lock) The Persistent Protection Bit Lock (PPB Lock) is a global volatile bit. When set to "1", the PPBs cannot be changed. When cleared ("0"), the PPBs are changeable. There is only one PPB Lock bit per device. The PPB Lock is cleared after power-up or hardware reset. There is no command sequence to unlock the PPB Lock. Dynamic Protection Bit (DYB) A volatile protection bit is assigned for each sector. After power-up or hardware reset, the contents of all DYBs is "0". Each DYB is individually modifiable through the DYB Write Command. When the par ts are first shipped, the PPBs are cleared, the DYBs are cleared, and PPB Lock is defaulted to power up in the cleared state - meaning the PPBs are changeable. When the device is first powered on the DYBs power up cleared (sectors not protected). The Protection State for each sector is determined by the logical OR of the PPB and the DYB related to that sector. For the sectors that have the PPBs cleared, the DYBs control whether or not the sector is protected or unprotected. By issuing the DYB Write command sequences, the DYBs will be set or cleared, thus placing each sector in the protected or unprotected state. These are the so-called Dynamic Locked or Unlocked states. They are called dynamic states because it is very easy to switch back and forth between the protected and unprotected conditions. This allows software to easily protect sectors against inadvertent changes yet does 35
Persistent Sector Protection
A command sector protection method that replaces the old 12 V controlled protection method.
Password Sector Protection
A highly sophisticated protection method that requires a password before changes to certain sectors or sector groups are permitted.
WP# Hardware Protection
A write protect pin that can prevent program or erase operations in sectors 0, 1, 268, and 269 in PDL 127 or in SA1-133, SA1-134, SA2-0, SA2-1 in PDL 129. The WP# Hardware Protection feature is always available, regardless of which of the other two methods are chosen.
Selecting a Sector Protection Mode
The device defaults to the Persistent Sector Protection mode. However, to prevents a program or virus from later setting the Password Mode Locking Bit, which would cause an unexpected shift from the default Persistent Sector Protection Mode into the Password Protection Mode, it is recommended that either of two one-time programmable non-volatile bits that permanently define which sector protection method be set before the device is first programmed. The Persistent Sector Protection Mode Locking Bit permanently sets the device to the Persistent Sector Protection mode. The Password Mode Locking Bit permanently sets the device to the Password Sector Protection mode. It is not possible to switch between the two protection modes once a locking bit has been set. The device is shipped with all sectors unprotected. AMD offers the option of programming and protecting sectors at the factory prior to shipping the device through AMD's ExpressFlashTM Service. Contact an AMD representative for details. It is possible to determine whether a sector is protected or unprotected. See Autoselect Command Sequence for details.
Persistent Sector Protection
The Persistent Sector Protection method replaces the 12 V controlled protection method in previous AMD flash devices. This new method provides three different sector protection states: Persistently Locked--The sector is protected and cannot be changed.

not prevent the easy removal of protection when changes are needed. The DYBs maybe set or cleared as often as needed. The PPBs allow for a more static, and difficult to change, level of protection. The PPBs retain their state across power cycles because they are non-volatile. Individual PPBs are set with a command but must all be cleared as a group through a complex sequence of program and erasing commands. The PPBs are also limited to 100 erase cycles. The PPB Lock bit adds an additional level of protection. Once all PPBs are programmed to the desired settings, the PPB Lock may be set to "1". Setting the PPB Lock disables all program and erase commands to the non-volatile PPBs. In effect, the PPB Lock Bit locks the PPBs into their current state. The only way to clear the PPB Lock is to go through a power cycle. System boot code can determine if any changes to the PPB are needed; for example, to allow new system code to be downloaded. If no changes are needed then the boot code can set the PPB Lock to disable any further changes to the PPBs during system operation. The WP#/ACC write protect pin adds a final level of hardware protection to sectors 0, 1, 268, and 269 in PDL 127 or in SA1-133, SA1-134, SA2-0, SA2-1 in PDL 129. When this pin is low it is not possible to change the contents of these sectors. These sectors generally hold system boot code. The WP#/ACC pin can prevent any changes to the boot code that could override the choices made while setting up sector protection during system initialization. It is possible to have sectors that have been persistently locked, and sectors that are left in the dynamic state. The sectors in the dynamic state are all unprotected. If there is a need to protect some of them, a simple DYB Write command sequence is all that is necessary. The DYB write command for the dynamic sectors switch the DYBs to signify protected and unprotected, respectively. If there is a need to change the status of the persistently locked sectors, a few more steps are required. First, the PPB Lock bit must be disabled by either putting the device through a power-cycle, or hardware reset. The PPBs can then be changed to reflect the desired settings. Setting the PPB lock bit once again will lock the PPBs, and the device operates normally again. The best protection is achieved by executing the PPB lock bit set command early in the boot code, and protect the boot code by holding WP#/ACC = VIL.

Table 11 contains all possible combinations of the DYB, PPB, and PPB lock relating to the status of the sector. In summary, if the PPB is set, and the PPB lock is set, the sector is protected and the protection can not be removed until the next power cycle clears the PPB lock. If the PPB is cleared, the sector can be dynamically locked or unlocked. The DYB then controls whether or not the sector is protected or unprotected. If the user attempts to program or erase a protected sector, the device ignores the command and returns to read mode. A program command to a protected sector enables status polling for approximately 1 s before the device returns to read mode without having modified the contents of the protected sector. An erase command to a protected sector enables status polling for approximately 50 s after which the device returns to read mode without having erased the protected sector.

Persistent Sector Protection Mode Locking Bit Like the password mode locking bit, a Persistent Sector Protection mode locking bit exists to guarantee that the device remain in software sector protection. Once set, the Persistent Sector Protection locking bit prevents programming of the password protection mode locking bit. This guarantees that a hacker could not place the device in password protection mode.
Password Protection Mode
The Password Sector Protection Mode method allows an even higher level of security than the Persistent Sector Protection Mode. There are two main differ-

INFORMATION The Password Mode Locking Bit, once set, prevents reading the 64-bit password on the DQ bus and further password programming. The Password Mode Locking Bit is not erasable. Once Password Mode Locking Bit is programmed, the Persistent Sector Protection Locking Bit is disabled from programming, guaranteeing that no changes to the protection scheme are allowed. 64-bit Password The 64-bit Password is located in its own memory space and is accessible through the use of the Password Program and Verify commands (see "Password Verify Command"). The password function works in conjunction with the Password Mode Locking Bit, which when set, prevents the Password Verify command from reading the contents of the password on the pins of the device.
ences between the Persistent Sector Protection and the Password Sector Protection Mode: When the device is first powered on, or comes out of a reset cycle, the PPB Lock bit set to the locked state, rather than cleared to the unlocked state. The only means to clear the PPB Lock bit is by writing a unique 64-bit Password to the device. The Password Sector Protection method is otherwise identical to the Persistent Sector Protection method. A 64-bit password is the only additional tool utilized in this method. Once the Password Mode Locking Bit is set, the password is permanently set with no means to read, program, or erase it. The password is used to clear the PPB Lock bit. The Password Unlock command must be written to the flash, along with a password. The flash device internally compares the given password with the pre-programmed password. If they match, the PPB Lock bit is cleared, and the PPBs can be altered. If they do not match, the flash device does nothing. There is a built-in 2 s delay for each "password check." This delay is intended to thwart any efforts to run a program that tries all possible combinations in order to crack the password. Password and Password Mode Locking Bit In order to select the Password sector protection scheme, the customer must first program the password. The password may be correlated to the unique Electronic Serial Number (ESN) of the particular flash device. Each ESN is different for every flash device; therefore each password should be different for every flash device. While programming in the password region, the customer may perform Password Verify operations. Once the desired password is programmed in, the customer must then set the Password Mode Locking Bit. This operation achieves two objectives: 1. Permanently sets the device to operate using the Password Protection Mode. It is not possible to reverse this function. 2. Disables all further commands to the password region. All program, and read operations are ignored. Both of these objectives are important, and if not carefully considered, may lead to unrecoverable errors. The user must be sure that the Password Protection method is desired when setting the Password Mode Locking Bit. More importantly, the user must be sure that the password is correct when the Password Mode Locking Bit is set. Due to the fact that read operations are disabled, there is no means to verify what the password is afterwards. If the password is lost after setting the Password Mode Locking Bit, there will be no way to clear the PPB Lock bit.
Write Protect (WP#)
The Write Protect feature provides a hardware method of protecting sectors 0, 1, 268, and 269 in PDL 127 or in SA1-133, SA1-134, SA2-0, SA2-1 in PDL 129 without using VID. This function is provided by the WP# pin and overrides the previously discussed High Voltage Sector Protection method. If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the two outermost 4 Kword sectors on both ends of the flash array independent of whether it was previously protected or unprotected. If the system asserts VIH on the WP#/ACC pin, the device reverts to whether sectors 0, 1, 268, and 269 in PDL 127 or in SA1-133, SA1-134, SA2-0, SA2-1 in PDL 129 were last set to be protected or unprotected. That is, sector protection or unprotection for these sectors depends on whether they were last protected or unprotected using the method described in High Voltage Sector Protection. Note that the WP#/ACC pin must not be left floating or unconnected; inconsistent behavior of the device may result. Persistent Protection Bit Lock The Persistent Protection Bit (PPB) Lock is a volatile bit that reflects the state of the Password Mode Locking Bit after power-up reset. If the Password Mode Lock Bit is also set after a hardware reset (RESET# asserted) or a power-up reset, the ONLY means for clearing the PPB Lock Bit in Password Protection Mode is to issue the Password Unlock command. Successful execution of the Password Unlock command clears the PPB Lock Bit, allowing for sector PPBs modifications. Asserting RESET#, taking the device through a power-on reset, or issuing the PPB Lock Bit Set command sets the PPB Lock Bit to a "1" when the Password Mode Lock Bit is not set.

INFORMATION
If the Password Mode Locking Bit is not set, including Persistent Protection Mode, the PPB Lock Bit is cleared after power-up or hardware reset. The PPB Lock Bit is set by issuing the PPB Lock Bit Set command. Once set the only means for clearing the PPB Lock Bit is by issuing a hardware or power-up reset. The Password Unlock command is ignored in Persistent Protection Mode.
High Voltage Sector Protection
Sector protection and unprotection may also be implemented using programming equipment. The procedure requires high voltage (VID ) to be placed on the RESET# pin. Refer to Figure 1 for details on this procedure. Note that for sector unprotect, all unprotected sectors must first be protected prior to the first sector write cycle.

INFORMATION indic at or bits ( DQ6, DQ7) to indic ate the fac tory-locked and customer-locked status of the part. The system accesses the SecSi Sector through a command sequence (see "Enter SecSiTM Sector/Exit SecSi Sector Command Sequence"). After the system has written the Enter SecSi Sector command sequence, it may read the SecSi Sector by using the addresses normally occupied by the boot sectors. This mode of operation continues until the system issues the Exit SecSi Sector command sequence, or until power is removed from the device. On power-up, or following a hardware reset, the device reverts to sending commands to the normal address space. Factory-Locked Area (64 words) T h e fa c t o r y - l o cke d a r e a o f t h e S e c S i S e c t o r (000000h-00003Fh) is locked when the par t is shipped, whether or not the area was programmed at the factory. The SecSi Sector Factory-locked Indicator Bit (DQ7) is permanently set to a "1". AMD offers the ExpressFlash service to program the factory-locked area with a random ESN, a customer-defined code, or any combination of the two. Because only AMD can program and protect the factory-locked area, this method ensures the security of the ESN once the product is shipped to the field. Contact an AMD representative for details on using AMD's ExpressFlash service. Note that the ACC function and unlock bypass modes are not available when the SecSi Sector is enabled. Customer-Lockable Area (64 words) The customer-lockable area of the SecSi Sector (000040h-00007Fh) is shipped unprotected, which allows the customer to program and optionally lock the area as appropriate for the application. The SecSi Sector Customer-locked Indicator Bit (DQ6) is shipped as "0" and can be permanently locked to "1" by issuing the SecSi Protection Bit Program Command. The SecSi Sector can be read any number of times, but can be programmed and locked only once. Note that the accelerated programming (ACC) and unlock bypass functions are not available when programming the SecSi Sector. The Customer-lockable SecSi Sector area can be protected using one of the following procedures: Follow the in-system sector protect algorithm as shown in Figure 3. This allows in-system protection of the Secsi Sector without raising any device pin to a high voltage. Note that this method is only applicable to the SecSi Sector. Once the SecSi Sector is locked and verified, the system must write the Exit SecSi Sector Region command sequence to return to reading and writing the remainder of the array.
Temporary Sector Unprotect
This feature allows temporary unprotection of previously protected sectors to change data in-system. The Sector Unprotect mode is activated by setting the RESET# pin to VID. During this mode, formerly protected sectors can be programmed or erased by selecting the sector addresses. Once VID is removed from the RESET# pin, all the previously protected sectors are protected again. Figure 2 shows the algorithm, and Figure 19 shows the timing diagrams, for this feature. While PPB lock is set, the device cannot enter the Temporary Sector Unprotection Mode.

COMMON FLASH MEMORY INTERFACE (CFI)
The Common Flash Interface (CFI) specification outlines device and host system software interrogation handshake, which allows specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and backward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility. This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address 55h, any time the device is ready to read array data. The system can read CFI information at the addresses given in Tables 12-15. To terminate reading CFI data, the system must write the reset command. The CFI Query mode is not accessible when the device is executing an Embedded Program or embedded Erase algorithm. The system can also write the CFI query command when the device is in the autoselect mode. The device enters the CFI query mode, and the system can read CFI data at the addresses given in Tables 12-15. The system must write the reset command to return the device to reading array data. For further information, please refer to the CFI Specification and CFI Publication 100, available via the World Wide Web at http://www.amd.com/flash/cfi. Alternatively, contact an AMD representative for copies of these documents.
Hardware Data Protection
The command sequence requirement of unlock cycles for programming or erasing provides data protection against inadvertent writes. In addition, the following hardware data protection measures prevent accidental erasure or programming, which might otherwise be caused by spurious system level signals during VCC power-up and power-down transitions, or from system noise. Low VCC Write Inhibit When VCC is less than V LKO, the device does not accept any write cycles. This protects data during VCC power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets to the read mode. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the proper signals to the control pins to prevent unintentional writes when V CC is greater than VLKO. Write Pulse "Glitch" Protection Noise pulses of less than 3 ns (typical) on OE#, CE#f1, CE#f2 or WE# do not initiate a write cycle. Logical Inhibit Write cycles are inhibited by holding any one of OE# = VIL, CE#f1 =CE#f2 = VIH or WE# = VIH. To initiate a

COMMAND DEFINITIONS
Writing specific address and data commands or sequences into the command register initiates device operations. Table 16 defines the valid register command sequences. Writing incorrect address and data values or writing them in the improper sequence may place the device in an unknown state. A reset command is then required to return the device to reading array data. All addresses are latched on the falling edge of WE# or CE#f1/CE#f2 (PDL129H only), whichever happens later. All data is latched on the rising edge of WE# or CE#f1/CE#f2 (PDL129H only), whichever happens first. Refer to the Flash AC Characteristics section for timing diagrams. erasing begins. This resets the bank to which the system was writing to the read mode. Once erasure begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in a program command sequence before programming begins. This resets the bank to which the system was writing to the read mode. If the program command sequence is written to a bank that is in the Erase Suspend mode, writing the reset com mand r etur ns that bank t o the erase- suspend-read mode. Once programming begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in an autoselect command sequence. Once in the autoselect mode, the reset command must be written to return to the read mode. If a bank entered the autoselect mode while in the Erase Suspend mode, writing the reset command returns that bank to the erase-suspend-read mode. If DQ5 goes high during a program or erase operation, writing the reset command returns the banks to the read mode (or erase-suspend-read mode if that bank was in Erase Suspend).
Reading Array Data
The device is automatically set to reading array data after device power-up. No commands are required to retrieve data. Each bank is ready to read array data after completing an Embedded Program or Embedded Erase algorithm. After the device accepts an Erase Suspend command, the corresponding bank enters the erase-suspend-read mode, after which the system can read data from any non-erase-suspended sector within the same bank. The system can read array data using the standard read timing, except that if it reads at an address within erase-suspended sectors, the device outputs status data. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See the Erase Suspend/Erase Resume Commands section for more information. The system must issue the reset command to return a bank to the read (or erase-suspend-read) mode if DQ5 goes high during an active program or erase operation, or if the bank is in the autoselect mode. See the next section, Reset Command, for more information. See also Requirements for Reading Array Data in the MCP Device Bus Operations section for more information. The Read-Only Operations - Am29PDL127H and Read-Only Operations - Am29PDL127H tables provide the read parameters, and Figure 12 shows the timing diagram.
Autoselect Command Sequence
The autoselect command sequence allows the host system to access the manufacturer and device codes, and determine whether or not a sector is protected. The autoselect command sequence may be written to an address within a bank that is either in the read or erase-suspend-read mode. The autoselect command may not be written while the device is actively programming or erasing in the other bank. The autoselect command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle that contains the bank address and the autoselect command. The bank then enters the autoselect mode. The system may read any number of autoselect codes without reinitiating the command sequence. Table 16 shows the address and data requirements. To determine sector protection information, the system must write to the appropriate bank address (BA) and sector address (SA). Table 4 shows the address range and bank number associated with each sector. The system must write the reset command to return to the read mode (or erase-suspend-read mode if the bank was previously in Erase Suspend).
Reset Command
Writing the reset command resets the banks to the read or erase-suspend-read mode. Address bits are don't cares for this command. The reset command may be written between the sequence cycles in an erase command sequence before

INFORMATION Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from "0" back to a "1." Attempting to do so may cause that bank to set DQ5 = 1, or cause the DQ7 and DQ6 status bits to indicate the operation was successful. However, a succeeding read will show that the data is still "0." Only erase operations can convert a "0" to a "1." Unlock Bypass Command Sequence The unlock bypass feature allows the system to program data to a bank faster than using the standard program command sequence. The unlock bypass command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. That bank then enters the unlock bypass mode. A two-cycle unlock bypass program command sequence is all that is required to program in this mode. The first cycle in this sequence contains the unlock bypass program command, A0h; the second cycle contains the program address and data. Additional data is programmed in the same manner. This mode dispenses with the initial two unlock cycles required in the standard program command sequence, resulting in faster total programming time. Table 16 shows the requirements for the command sequence. During the unlock bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands are valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock bypass reset command sequence. The device offers accelerated program operations through the WP#/ACC pin. When the system asserts VHH on the WP#/ACC pin, the device automatically enters the Unlock Bypass mode. The system may then write the two-cycle Unlock Bypass program command sequence. The device uses the higher voltage on the WP#/ACC pin to accelerate the operation. Note that the WP#/ACC pin must not be at VHH any operation other than accelerated programming, or device damage may result. In addition, the WP#/ACC pin must not be left floating or unconnected; inconsistent behavior of the device may result. Figure 3 illustrates the algorithm for the program operation. Refer to the Erase and Program Operations table in the AC Characteristics section for parameters, and Figures 12 and 13 for timing diagrams.
Enter SecSiTM Sector/Exit SecSi Sector Command Sequence
The SecSi Sector region provides a secured data area containing a random, eight word electronic serial number (ESN). The system can access the SecSi Sector region by issuing the three-cycle Enter SecSi Sector command sequence. The device continues to access the SecSi Sector region until the system issues the four-cycle Exit SecSi Sector command sequence. The Exit SecSi Sector command sequence returns the device to normal operation. The SecSi Sector is not accessible when the device is executing an Embedded Program or embedded Erase algorithm. Table 16 shows the address and data requirements for both command sequences. See also "SecSiTM (Secured Silicon) Sector Flash Memory Region" for further information. Note that the ACC function and unlock bypass modes are not available when the SecSi Sector is enabled.
Word Program Command Sequence
Programming is a four-bus-cycle operation. The program command sequence is initiated by writing two unlock write cycles, followed by the program set-up command. The program address and data are written next, which in turn initiate the Embedded Program algorithm. The system is not required to provide further controls or timings. The device automatically provides internally generated program pulses and verifies the programmed cell margin. Table 16 shows the address and data requirements for the program command sequence. When the Embedded Program algorithm is complete, that bank then returns to the read mode and addresses are no longer latched. The system can determine the status of the program operation by using DQ7, DQ6, or RY/BY#. Refer to the Write Operation Status section for information on these status bits. Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a hardware reset immediately terminates the program operation. Note that the SecSi sector, autoselect, and CFI functions are unavailable when the SecSi Sector is enabled. The program command sequence should be reinitiated once that bank has returned to the read mode, to ensure data integrity.

Sector Erase Command Sequence
Sector erase is a six bus cycle operation. The sector erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock cycles are written, and are then followed by the address of the sector to be erased, and the sector erase command.Table 16 shows the address and data requirements for the sector erase command sequence. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically programs and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. After the command sequence is written, a sector erase time-out of 50 s occurs. During the time-out period, additional sector addresses and sector erase commands may be written. Loading the sector erase buffer may be done in any sequence, and the number of sectors may be from one sector to all sectors. The time between these additional cycles must be less than 50 s, otherwise erasure may begin. Any sector erase address and command following the exceeded time-out may or may not be accepted. It is recommended that processor interrupts be disabled during this time to ensure all commands are accepted. The interrupts can be re-enabled after the last Sector Erase command is written. Any command other than Sector Erase or Erase Suspend during the time-out period resets that bank to the read mode. Note that the SecSi sector, autoselect, and CFI functions are unavailable when the SecSi Sector is enabled. The system must rewrite the command sequence and any additional addresses and commands. The system can monitor DQ3 to determine if the sector erase timer has timed out (See the section on DQ3: Sector Erase Timer). The time-out begins from the rising edge of the final WE# pulse in the command sequence. When the Embedded Erase algorithm is complete, the bank returns to reading array data and addresses are no longer latched. Note that while the Embedded Erase operation is in progress, the system can read data from the non-erasing bank. The system can de-

Chip Erase Command Sequence
Chip erase is a six bus cycle operation. The chip erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase command, which in turn invokes the Embedded Erase algorithm. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. Table 16 shows the address and data requirements for the chip erase command sequence. When the Embedded Erase algorithm is complete, that bank returns to the read mode and addresses are no longer latched. The system can determine the status of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. Refer to the Write Operation Status section for information on these status bits. Any commands written during the chip erase operation are ignored. However, note that a hardware reset immediately terminates the erase operation. Note that

INFORMATION period during the sector erase command sequence. The Erase Suspend command is ignored if written during the chip erase operation or Embedded Program algorithm. When the Erase Suspend command is written during the sector erase operation, the device requires a maximum of 20 s to suspend the erase operation. However, when the Erase Suspend command is written during the sector erase time-out, the device immediately terminates the time-out period and suspends the erase operation. Addresses are "don't-cares" when writing the Erase suspend command. After the erase operation has been suspended, the bank enters the erase-suspend-read mode. The system can read data from or program data to any sector not selected for erasure. (The device "erase suspends" all sectors selected for erasure.) Reading at any address within erase-suspended sectors produces status information on DQ7-DQ0. The system can use DQ7, or DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. Refer to the Write Operation Status section for information on these status bits. After an erase-suspended program operation is complete, the bank returns to the erase-suspend-read mode. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard Word Program operation. Refer to the Write Operation Status section for more information. In the erase-suspend-read mode, the system can also issue the autoselect command sequence. The device allows reading autoselect codes even at addresses within erasing sectors, since the codes are not stored in the memory array. When the device exits the autoselect mode, the device reverts to the Erase Suspend mode, and is ready for another valid operation. Refer to the Autoselect Command Sequence sections for details. To resume the sector erase operation, the system must write the Erase Resume command (address bits are don't care). The bank address of the erase-suspended bank is required when writing this command. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the chip has resumed erasing.
termine the status of the erase operation by reading DQ7, DQ6, DQ2, or RY/BY# in the erasing bank. Refer to the Write Operation Status section for information on these status bits. Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the sector erase command sequence should be reinitiated once that bank has returned to reading array data, to ensure data integrity. Figure 4 illustrates the algorithm for the erase operation.

Erase Suspend/Erase Resume Commands
The Erase Suspend command, B0h, allows the system to interrupt a sector erase operation and then read data from, or program data to, any sector not selected for erasure. The bank address is required when writing this command. This command is valid only during the sector erase operation, including the 80 s time-out
Password Program Command
The Password Program Command permits programming the password that is used as part of the hardware protection scheme. The actual password is 64-bits long. Four Password Program commands are required to program the password. The system must enter the unlock cycle, password program command (38h) and the program address/data for each portion

INFORMATION
of the password when programming. There are no provisions for entering the 2-cycle unlock cycle, the password program command, and all the password data. There is no special addressing order required for programming the password. Also, when the password is undergoing programming, Simultaneous Operation is disabled. Read operations to any memory location will return the programming status. Once programming is complete, the user must issue a Read/Reset command to return the device to normal operation. Once the Password is written and verified, the Password Mode Locking Bit must be set in order to prevent verification. The Password Program Command is only capable of programming "0"s. Programming a "1" after a cell is programmed as a "0" results in a time-out by the Embedded Program AlgorithmTM with the cell remaining as a "0". The password is all ones when shipped from the factory. All 64-bit password combinations are valid as a password.
Persistent Sector Protection Mode Locking Bit Program Command
The Persistent Sector Protection Mode Locking Bit Program Command programs the Persistent Sector Protection Mode Locking Bit, which prevents the Password Mode Locking Bit from ever being programmed. If the Persistent Sector Protection Mode Locking Bit is verified as programmed without margin, the Persistent Sector Protection Mode Locking Bit Program Command should be reissued to improve program margin. By disabling the program circuitry of the Password Mode Locking Bit, the device is forced to remain in the Persistent Sector Protection mode of operation, once this bit is set. Exiting the Persistent Protection Mode Locking Bit Program command is accomplished by writing the Read/Reset command.
SecSi Sector Protection Bit Program Command
The SecSi Sector Protection Bit Program Command programs the SecSi Sector Protection Bit, which prevents the SecSi sector memory from being cleared. If the SecSi Sector Protection Bit is verified as programmed without margin, the SecSi Sector Protection Bit Program Command should be reissued to improve program margin. Exiting the V CC -level SecSi Sector Protection Bit Program Command is accomplished by writing the Read/Reset command.
Password Verify Command
The Password Verify Command is used to verify the Password. The Password is verifiable only when the Password Mode Locking Bit is not programmed. If the Password Mode Locking Bit is programmed and the user attempts to verify the Password, the device will always drive all F's onto the DQ data bus. The Password Verify command is permitted if the SecSi sector is enabled. Also, the device will not operate in Simultaneous Operation when the Password Verify command is executed. Only the password is returned regardless of the bank address. The lower two address bits (A1-A0) are valid during the Password Verify. Writing the Read/Reset command returns the device back to normal operation.
PPB Lock Bit Set Command
The PPB Lock Bit Set command is used to set the PPB Lock bit if it is cleared either at reset or if the Password Unlock command was successfully executed. There is no PPB Lock Bit Clear command. Once the PPB Lock Bit is set, it cannot be cleared unless the device is taken through a power-on clear or the Password Unlock command is executed. Upon setting the PPB Lock Bit, the PPBs are latched into the DYBs. If the Password Mode Locking Bit is set, the PPB Lock Bit status is reflected as set, even after a power-on reset cycle. Exiting the PPB Lock Bit Set command is accomplished by writing the Read/Reset command (only in the Persistent Protection Mode).
Password Protection Mode Locking Bit Program Command
The Password Protection Mode Locking Bit Program Command programs the Password Protection Mode Locking Bit, which prevents further verifies or updates to the Password. Once programmed, the Password Protection Mode Locking Bit cannot be erased! If the Password Protection Mode Locking Bit is verified as program without margin, the Password Protection Mode Locking Bit Program command can be executed to improve the program margin. Once the Password Protection Mode Locking Bit is programmed, the Persistent Sector Protection Locking Bit program circuitry is disabled, thereby forcing the device to remain in the Password Protection mode. Exiting the Mode Locking Bit Program command is accomplished by writing the Read/Reset command.
DYB Write Command
The DYB Write command is used to set or clear a DYB for a given sector. The high order address bits A22-A12 for PDL127 and (A21-A12) for PDL129H are issued at the same time as the code 01h or 00h on DQ7-DQ0. All other DQ data bus pins are ignored during the data write cycle. The DYBs are modifiable at any time, regardless of the state of the PPB or PPB Lock Bit. The DYBs are cleared at power-up or hardware reset. Exiting the DYB Write command is accomplished by writing the Read/Reset command.

INFORMATION determine whether the PPB has been erased with margin. If the PPBs has been erased without margin, the erase command should be reissued to improve the program margin. It is the responsibility of the user to preprogram all PPBs prior to issuing the All PPB Erase command. If the user attempts to erase a cleared PPB, over-erasure may occur making it difficult to program the PPB at a later time. Also note that the total number of PPB program/erase cycles is limited to 100 cycles. Cycling the PPBs beyond 100 cycles is not guaranteed.
Password Unlock Command
The Password Unlock command is used to clear the PPB Lock Bit so that the PPBs can be unlocked for modification, thereby allowing the PPBs to become accessible for modification. The exact password must be entered in order for the unlocking function to occur. This command cannot be issued any faster than 2 s at a time to prevent a hacker from running through all 64-bit combinations in an attempt to correctly match a password. If the command is issued before the 2 s execution window for each portion of the unlock, the command will be ignored. Once the Password Unlock command is entered, the RY/BY# indicates that the device is busy. Approximately 1 s is required for each portion of the unlock. Once the first portion of the password unlock completes (RY/BY# is not low or DQ6 does not toggle when read), the next part of the password is written. The system must thus monitor RY/BY# or the status bits to confirm when to write the next portion of the password. Seven cycles are required to successfully clear the PPB Lock Bit.
DYB Write Command
The DYB Write command is used for setting the DYB, which is a volatile bit that is cleared at reset. There is one DYB per sector. If the PPB is set, the sector is protected regardless of the value of the DYB. If the PPB is cleared, setting the DYB to a 1 protects the sector from programs or erases. Since this is a volatile bit, removing power or resetting the device will clear the DYBs. The bank address is latched when the command is written.
PPB Program Command
The PPB Program command is used to program, or set, a given PPB. Each PPB is individually programmed (but is bulk erased with the other PPBs). The specific sector address (A21-A12) are written at the same time as the program command 60h with A6 = 0. If the PPB Lock Bit is set and the corresponding PPB is set for the sector, the PPB Program command will not execute and the command will time-out without programming the PPB.
PPB Lock Bit Set Command
The PPB Lock Bit set command is used for setting the DYB, which is a volatile bit that is cleared at reset. There is one DYB per sector. If the PPB is set, the sector is protected regardless of the value of the DYB. If the PPB is cleared, setting the DYB to a 1 protects the sector from programs or erases. Since this is a volatile bit, removing power or resetting the device will clear the DYBs. The bank address is latched when the command is written.
After programming a PPB, two additional cycles are needed to determine whether the PPB has been programmed with margin. If the PPB has been programmed without margin, the program command should be reissued to improve the program margin. Also note that the total number of PPB program/erase cycles is limited to 100 cycles. Cycling the PPBs beyond 100 cycles is not guaranteed.
The PPB Program command does not follow the Embedded Program algorithm.
PPB Status Command
The programming of the PPB for a given sector can be verified by writing a PPB status verify command to the device.
PPB Lock Bit Status Command
The programming of the PPB Lock Bit for a given sector can be verified by writing a PPB Lock Bit status verify command to the device.
All PPB Erase Command
The All PPB Erase command is used to erase all PPBs in bulk. There is no means for individually erasing a specific PPB. Unlike the PPB program, no specific sector address is required. However, when the PPB erase command is written all Sector PPBs are erased in parallel. If the PPB Lock Bit is set the ALL PPB Erase command will not execute and the command will time-out without erasing the PPBs. After erasing the PPBs, two additional cycles are needed to
Sector Protection Status Command
The programming of either the PPB or DYB for a given sector or sector group can be verified by writing a Sector Protection Status command to the device. Note that there is no single command to independently verify the programming of a DYB for a given sector group.

INFORMATION
WRITE OPERATION STATUS
The device provides several bits to determine the status of a program or erase operation: DQ2, DQ3, DQ5, DQ6, and DQ7. Table 18 and the following subsections describe the function of these bits. DQ7 and DQ6 each offer a method for determining whether a program or erase operation is complete or in progress. The device also provides a hardware-based output signal, RY/BY#, to determine whether an Embedded Program or Erase operation is in progress or has been completed. pleted the program or erase operation and DQ7 has valid data, the data outputs on DQ15-DQ0 may be still invalid. Valid data on DQ15-DQ0 will appear on successive read cycles. Table 18 shows the outputs for Data# Polling on DQ7. Figure 5 shows the Data# Polling algorithm. Figure 5 in the Flash AC Characteristics section shows the Data# Polling timing diagram.
DQ7: Data# Polling
The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Program or Erase algorithm is in progress or completed, or whether a bank is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the command sequence. During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When the Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program address falls within a protected sector, Data# Polling on DQ7 is active for approximately 1 s, then that bank returns to the read mode. During the Embedded Erase algorithm, Data# Polling produces a "0" on DQ7. When the Embedded Erase algorithm is complete, or if the bank enters the Erase Suspend mode, Data# Polling produces a "1" on DQ7. The system must provide an address within any of the sectors selected for erasure to read valid status information on DQ7. After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling on DQ7 is active for approximately 400 s, then the bank returns to the read mode. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. However, if the system reads DQ7 at an address within a protected sector, the status may not be valid. When the system detects DQ7 has changed from the complement to true data, it can read valid data at DQ15-DQ0 on the following read cycles. Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with DQ15-DQ0 while Output Enable (OE#) is asserted low. That is, the device may change from providing status information to valid data on DQ7. Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device has comSTART

Notes: 1. VA = Valid address for programming. During a sector erase operation, a valid address is any sector address within the sector being erased. During chip erase, a valid address is any non-protected sector address. 2. DQ7 should be rechecked even if DQ5 = "1" because DQ7 may change simultaneously with DQ5.

INFORMATION DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete. Table 18 shows the outputs for Toggle Bit I on DQ6. Figure 6 shows the toggle bit algorithm. Figure 17 in the "Flash AC Characteristics" section shows the toggle bit timing diagrams. Figure 18 shows the differences between DQ2 and DQ6 in graphical form. See also the subsection on DQ2: Toggle Bit II.
RY/BY#: Ready/Busy#
The RY/BY# is a dedicated, open-drain output pin which indicates whether an Embedded Algorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in the command sequence. Since RY/BY# is an open-drain output, several RY/BY# pins can be tied together in parallel with a pull-up resistor to VCC. If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.) If the output is high (Ready), the device is in the read mode, the standby mode, or one of the banks is in the erase-suspend-read mode. Table 18 shows the outputs for RY/BY#.
START
DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete, or whether the device has entered the Erase Suspend mode. Toggle Bit I may be read at any address, and is valid after the rising edge of the final WE# pulse in the command sequence (prior to the program or erase operation), and during the sector erase time-out. During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. The system may use either OE# or CE#f1 to control the read cycles. When the operation is complete, DQ6 stops toggling. After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for approximately 400 s, then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erase-suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6 toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use DQ7 (see the subsection on DQ7: Data# Polling). If a program address falls within a protected sector, DQ6 toggles for approximately 1 s after the program command sequence is written, then returns to reading array data.

INFORMATION The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not gone high. The system may continue to monitor the toggle bit and DQ5 through successive read cycles, determining the status as described in the previous paragraph. Alternatively, it may choose to perform other system tasks. In this case, the system must start at the beginning of the algorithm when it returns to determine the status of the operation (top of Figure 6).
DQ2: Toggle Bit II
The "Toggle Bit II" on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that is, the Embedded Erase algorithm is in progress), or whether that sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final WE# pulse in the command sequence. DQ2 toggles when the system reads at addresses within those sectors that have been selected for erasure. (The system may use either OE# or CE#f1 to control the read cycles.) But DQ2 cannot distinguish whether the sector is actively erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sector and mode information. Refer to Table 18 to compare outputs for DQ2 and DQ6. Figure 6 shows the toggle bit algorithm in flowchart form, and the section "DQ2: Toggle Bit II" explains the algorithm. See also the DQ6: Toggle Bit I subsection. Figure 17 shows the toggle bit timing diagram. Figure 18 shows the differences between DQ2 and DQ6 in graphical form.
DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under these conditions DQ5 produces a "1," indicating that the program or erase cycle was not successfully completed. The device may output a "1" on DQ5 if the system tries to program a "1" to a location that was previously programmed to "0." Only an erase operation can change a "0" back to a "1." Under this condition, the device halts the operation, and when the timing limit has been exceeded, DQ5 produces a "1." Under both these conditions, the system must write the reset command to return to the read mode (or to the erase-suspend-read mode if a bank was previously in the erase-suspend-program mode).
Reading Toggle Bits DQ6/DQ2
Refer to Figure 6 for the following discussion. Whenever the system initially begins reading toggle bit status, it must read DQ7-DQ0 at least twice in a row to determine whether a toggle bit is toggling. Typically, the system would note and store the value of the toggle bit after the first read. After the second read, the system would compare the new value of the toggle bit with the first. If the toggle bit is not toggling, the device has completed the program or erase operation. The system can read array data on DQ7-DQ0 on the following read cycle. However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note whether the value of DQ5 is high (see the section on DQ5). If it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5 went high. If the toggle bit is no longer toggling, the device has successfully completed the program or erase operation. If it is still toggling, the device did not completed the operation successfully, and the system must write the reset command to return to reading array data.
DQ3: Sector Erase Timer
After writing a sector erase command sequence, the system may read DQ3 to determine whether or not erasure has begun. (The sector erase timer does not apply to the chip erase command.) If additional sectors are selected for erasure, the entire time-out also applies after each additional sector erase command. When the time-out period is complete, DQ3 switches from a "0" to a "1." See also the Sector Erase Command Sequence section. After the sector erase command is written, the system should read the status of DQ7 (Data# Polling) or DQ6 (Toggle Bit I) to ensure that the device has accepted the command sequence, and then read DQ3. If DQ3 is "1," the Embedded Erase algorithm has begun; all further commands (except Erase Suspend) are ignored until the erase operation is complete. If DQ3 is "0," the device will accept additional sector erase commands. To ensure the command has been accepted, the system software should check the status of DQ3 prior to and following each subsequent sector erase command. If DQ3 is high on the second status check, the last command might not have been accepted. Table 18 shows the status of DQ3 relative to the other status bits.

GENERAL DESCRIPTION (LV640M)
The Am29LV640MH is a 64 Mbit, 3.0 volt single power supply flash memory device organized as 4,194,304 words. The device has an 8-bit/16-bit bus and can be programmed either in the host system or in standard EPROM programmers. An access time of 110 ns is available. Each device requires only a single 3.0 volt power supply for both read and write functions. In addition to a VCC input, a high-voltage accelerated program (ACC) feature provides shorter programming times through increased current on the WP#/ACC input. This feature is intended to facilitate factory throughput during system production, but may also be used in the field if desired. The device is entirely command set compatible with the JEDEC single-power-supply Flash standard. Commands are written to the device using standard microprocessor write timing. Write cycles also internally latch addresses and data needed for the programming and erase operations. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory. Device programming and erasure are initiated through command sequences. Once a program or erase operation has begun, the host system need only poll the DQ7 (Data# Polling) or DQ6 (toggle) status bits or monitor the Ready/Busy# (RY/BY#) output to determine whether the operation is complete. To facilitate programming, an Unlock Bypass mode reduces command sequence overhead by requiring only two write cycles to program data instead of four. The Versatile I/OTM (VIO) control allows the host system to set the voltage levels that the device generates and tolerates on the CE# control input and DQ I/Os to the same voltage level that is asserted on the VIO pin. Refer to the Ordering Information section for valid VIO options. Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of sectors of memory. This can be achieved in-system or via programming equipment. The Erase Suspend/Erase Resume feature allows the host system to pause an erase operation in a given sector to read or program any other sector and then complete the erase operation. The Program Suspend/Program Resume feature enables the host system to pause a program operation in a given sector to read any other sector and then complete the program operation. The hardware RESET# pin terminates any operation in progress and resets the device, after which it is then ready for a new operation. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the host system to read boot-up firmware from the Flash memory device. The device reduces power consumption in the standby mode when it detects specific voltage levels on CE# and RESET#, or when addresses have been stable for a specified period of time. The Write Protect (WP#) feature protects the first or last sector by asserting a logic low on the WP#/ACC pin. The protected sector will still be protected even during accelerated programming. The SecSiTM (Secured Silicon) Sector provides a 128-word area for code or data that can be permanently protected. Once this sector is protected, no further changes within the sector can occur. AMD MirrorBit flash technology combines years of Flash memory manufacturing experience to produce the highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a sector simultaneously via hot-hole assisted erase. The data is programmed using hot electron injection.

DEVICE BUS OPERATIONS
This section describes the requirements and use of the device bus operations, which are initiated through the internal command register. The command register itself does not occupy any addressable memory location. The register is a latch used to store the commands, along with the address and data information needed to execute the command. The contents of the Table 1.

Addresses are A21:A0 in word mode. 2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the "Sector Group Protection and Unprotection" section. 3. If WP# = VIL, the first or last sector remains protected. If WP# = VIH, the first or last sector will be protected or unprotected as determined by the method described in "Sector Group Protection and Unprotection". All sectors are unprotected when shipped from the factory (The SecSi Sector may be factory protected depending on version ordered.) 4. DIN or DOUT as required by command sequence, data polling, or sector protect algorithm (see Figure 2).
VersatileIOTM (VIO) Control
The VersatileIOTM (VIO) control allows the host system to set the voltage levels that the device generates and tolerates on CE# and DQ I/Os to the same voltage level that is asserted on VIO. See "Ordering Information" on page 9 for VIO options on this device. For example, a VI/O of 1.65-3.6 volts allows for I/O at the 1.8 or 3 volt levels, driving and receiving signals to and from other 1.8 or 3 V devices on the same data bus.
Requirements for Reading Array Data
To read array data from the outputs, the system must drive the CE# and OE# pins to VIL. CE# is the power control and selects the device. OE# is the output control and gates array data to the output pins. WE# should remain at VIH. The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data.

INFORMATION Write Buffer Write Buffer Programming allows the system to write a maximum of 16 words/32 bytes in one programming operation. This results in faster effective programming time than the standard programming algorithms. See "Write Buffer" for more information. Accelerated Program Operation The device offers accelerated program operations through the ACC function. This is one of two functions provided by the WP#/ACC pin. This function is primarily intended to allow faster manufacturing throughput at the factory. If the system asserts VHH on this pin, the device automatically enters the aforementioned Unlock Bypass mode, temporarily unprotects any protected sectors, and uses the higher voltage on the pin to reduce the time required for program operations. The system would use a two-cycle program command sequence as required by the Unlock Bypass mode. Removing VHH from the WP#/ACC pin returns the device to normal operation. Note that the WP#/ACC pin must not be at VHH for operations other than accelerated programming, or device damage may result. In addition, no external pullup is necessary since the WP#/ACC pin has internal pullup to VCC. Autoselect Functions If the system writes the autoselect command sequence, the device enters the autoselect mode. The system can then read autoselect codes from the internal register (which is separate from the memory array) on DQ7-DQ0. Standard read cycle timings apply in this mode. Refer to the Autoselect Mode and Autoselect Command Sequence sections for more information.
Standard microprocessor read cycles that assert valid addresses on the device address inputs produce valid data on the device data outputs. The device remains enabled for read access until the command register contents are altered. See "Reading Array Data" for more information. Refer to the AC Read-Only Operations table for timing specifications and to Figure 14 for the timing diagram. Refer to the DC Characteristics table for the active current specification on reading array data. Page Mode Read The device is capable of fast page mode read and is compatible with the page mode Mask ROM read operation. This mode provides faster read access speed for random locations within a page. The page size of the device is 4 words/8 bytes. The appropriate page is selected by the higher address bits A(max)-A2. Address bits A1-A0 in word mode (A1-A-1 in byte mode) determine the specific word within a page. This is an asynchronous operation; the microprocessor supplies the specific word location. The random or initial page access is equal to tACC or tCE and subsequent page read accesses (as long as the locations specified by the microprocessor falls within that page) is equivalent to tPACC. When CE# is deasserted and reasserted for a subsequent access, the access time is tACC or t CE . Fast page mode accesses are obtained by keeping the "read-page addresses" constant and changing the "intra-read page" addresses.
Writing Commands/Command Sequences
To write a command or command sequence (which includes programming data to the device and erasing sectors of memory), the system must drive WE# and CE# to VIL, and OE# to VIH. The device features an Unlock Bypass mode to facilitate faster programming. Once the device enters the Unlock Bypass mode, only two write cycles are required to program a word or byte, instead of four. The "Word/Byte Program Command Sequence" section has details on programming data to the device using both standard and Unlock Bypass command sequences. An erase operation can erase one sector, multiple sectors, or the entire device. Table 2 indicates the address space that each sector occupies. Refer to the DC Characteristics table for the active current specification for the write mode. The AC Characteristics section contains timing specification tables and timing diagrams for write operations.
Standby Mode
When the system is not reading or writing to the device, it can place the device in the standby mode. In this mode, current consumption is greatly reduced, and the outputs are placed in the high impedance state, independent of the OE# input. The device enters the CMOS standby mode when the CE# and RESET# pins are both held at VIO 0.3 V. (Note that this is a more restricted voltage range than VIH.) If CE# and RESET# are held at VIH, but not within VIO 0.3 V, the device will be in the standby mode, but the standby current will be greater. The device requires standard access time (t CE ) for read access when the device is in either of these standby modes, before it is ready to read data. If the device is deselected during erasure or programming, the device draws active current until the operation is completed.

INFORMATION pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data integrity. Current is reduced for the duration of the RESET# pulse. When RESET# is held at VSS0.3 V, the device draws CMOS standby current (ICC4). If RESET# is held at VIL but not within VSS0.3 V, the standby current will be greater. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the Flash memory, enabling the system to read the boot-up firmware from the Flash memory. Refer to the AC Characteristics tables for RESET# parameters and to Figure 16 for the timing diagram.
Refer to the DC Characteristics table for the standby current specification.
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when addresses remain stable for t ACC + 30 ns. The automatic sleep mode is independent of the CE#, WE#, and OE# control signals. Standard address access timings provide new data when addresses are changed. While in sleep mode, output data is latched and always available to the system. Refer to the DC Characteristics table for the automatic sleep mode current specification.
RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates all output pins, and ignores all read/write commands for the duration of the RESET#
Output Disable Mode
When the OE# input is at VIH, output from the device is disabled. The output pins are placed in the high impedance state.

Sector Group Protection and Unprotection
The hardware sector group protection feature disables both program and erase operations in any sector group. In this device, a sector group consists of four adjacent sectors that are protected or unprotected at the same time (see Table 4). The hardware sector group unprotection feature re-enables both program and erase operations in previously protected sector groups. Sector group protection/unprotection can be implemented via two methods. Sector protection/unprotection requires VID on the RESET# pin only, and can be implemented either in-system or via programming equipment. Figure 2 shows the algorithms and Figure 24 shows the timing diagram. This method uses standard microprocessor bus cycle timing. For sector group unprotect, all unprotected sector groups must first be protected prior to the first sector group unprotect write cycle. The device is shipped with all sector groups unprotected. AMD offers the option of programming and protecting sector groups at its factory prior to shipping the device through AMD's ExpressFlashTM Service. Contact an AMD representative for details. It is possible to determine whether a sector group is protected or unprotected. See the Autoselect Mode section for details. Table 3. Sector Group Protection/Unprotection Address Table

INFORMATION
Write Protect (WP#)
The Write Protect function provides a hardware method of protecting the first or last sector without using VID. Write Protect is one of two functions provided by the WP#/ACC input. If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the first or last sector independently of whether those sectors were protected or unprotected using the method described in "Sector Group Protection and Unprotection". Note that if WP#/ACC is at VIL when the device is in the standby mode, the maximum input load current is increased. See the table in "DC Characteristics". If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the first or last sector was previously set to be protected or unprotected using the method described in "Sector Group Protection and Unprotection". Note: No external pullup is necessary since the WP#/ACC pin has internal pullup to VCC.

Temporary Sector Group Unprotect
(Note: In this device, a sector group consists of four adjacent sectors that are protected or unprotected at the same time (see Table 4).
This feature allows temporary unprotection of previously protected sector groups to change data in-system. The Sector Group Unprotect mode is activated by setting the RESET# pin to VID. During this mode, formerly protected sector groups can be programmed or erased by selecting the sector group addresses. Once VID is removed from the RESET# pin, all the previously protected sector groups are protected again. Figure 1 shows the algorithm, and Figure 23 shows the timing diagrams, for this feature.
Notes: 1. All protected sector groups unprotected (If WP# = VIL, the first or last sector will remain protected). 2. All previously protected sector groups are protected once again.

INFORMATION The system may program the SecSi Sector using the write-buffer, accelerated and/or unlock bypass methods, in addition to the standard programming command sequence. See Command Definitions. Programming and protecting the SecSi Sector must be used with caution since, once protected, there is no procedure available for unprotecting the SecSi Sector area and none of the bits in the SecSi Sector memory space can be modified in any way. The SecSi Sector area can be protected using one of the following procedures: Write the three-cycle Enter SecSi Sector Regioncommand sequence, and then follow the in-system sector protect algorithm as shown in Figure 2, except that RESET# may be at either VIH or VID. This allows in-system protection of the SecSi Sector without raising any device pin to a high voltage. Note that this method is only applicable to the SecSi Sector. To verify the protect/unprotect status of the SecSi Sector, follow the algorithm shown in Figure 3. Once the SecSi Sector is programmed, locked and verified, the system must write the Exit SecSi Sector Region command sequence to return to reading and writing within the remainder of the array.
SecSi (Secured Silicon) Sector Flash Memory Region
The SecSi (Secured Silicon) Sector feature provides a Flash memory region that enables permanent part identification through an Electronic Serial Number (ESN). The SecSi Sector is 128 words in length, and uses a SecSi Sector Indicator Bit (DQ7) to indicate whether or not the SecSi Sector is locked when shipped from the factory. This bit is permanently set at the factory and cannot be changed, which prevents cloning of a factory locked part. This ensures the security of the ESN once the product is shipped to the field. AMD offers the device with the SecSi Sector either factor y locked or cust omer lockable. The factory-locked version is always protected when shipped from the factory, and has the SecSi (Secured Silicon) Sector Indicator Bit permanently set to a "1." The customer-lockable version is shipped with the SecSi Sector unprotected, allowing customers to program the sector after receiving the device. The customer-lockable version also has the SecSi Sector Indicator Bit permanently set to a "0." Thus, the SecSi Sector Indicator Bit prevents customer-lockable devices from being used to replace devices that are factory locked. The SecSi sector address space in this device is allocated as follows: Table 4.

The system accesses the SecSi Sector through a command sequence (see "Enter SecSi Sector/Exit SecSi Sector Command Sequence"). After the system has written the Enter SecSi Sector command sequence, it may read the SecSi Sector by using the addresses normally occupied by the first sector (SA0). This mode of operation continues until the system issues the Exit SecSi Sector command sequence, or until power is removed from the device. On power-up, or following a hardware reset, the device reverts to sending commands to sector SA0. Customer Lockable: SecSi Sector NOT Programmed or Protected At the Factory As an alternative to the factory-locked version, the device may be ordered such that the customer may program and protect the 128-word SecSi sector. See Table 5 for SecSi Sector addressing.
If data = 00h, SecSi Sector is unprotected. If data = 01h, SecSi Sector is protected.

INFORMATION pins to prevent unintentional writes when V CC is greater than VLKO. Write Pulse "Glitch" Protection Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle. Logical Inhibit Write cycles are inhibited by holding any one of OE# = VIL, CE# = VIH or WE# = VIH. To initiate a write cycle, CE# and WE# must be a logical zero while OE# is a logical one. Power-Up Write Inhibit If WE# = CE# = VIL and OE# = VIH during power up, the device does not accept commands on the rising edge of WE#. The internal state machine is automatically reset to the read mode on power-up.
Hardware Data Protection
The command sequence requirement of unlock cycles for programming or erasing provides data protection against inadvertent writes (refer to Tables 10 and 11 for command definitions). In addition, the following hardware data protection measures prevent accidental erasure or programming, which might otherwise be caused by spurious system level signals during VCC power-up and power-down transitions, or from system noise. Low VCC Write Inhibit When VCC is less than V LKO, the device does not accept any write cycles. This protects data during VCC power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets to the read mode. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the proper signals to the control
COMMON FLASH MEMORY INTERFACE (CFI)
The Common Flash Interface (CFI) specification outlines device and host system software interrogation handshake, which allows specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and backward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility. This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address 55h, any time the device is ready to read array data. The system can read CFI information at the addresses given in Tables 6-9. To terminate reading CFI data, the system must write the reset command. Table 5.

COMMAND DEFINITIONS
Writing specific address and data commands or sequences into the command register initiates device operations. Tables 10 and 11 define the valid register command sequences. Writing incorrect address and data values or writing them in the improper sequence may place the device in an unknown state. A reset command is then required to return the device to reading array data. All addresses are latched on the falling edge of WE# or CE#, whichever happens later. All data is latched on the rising edge of WE# or CE#, whichever happens first. Refer to the AC Characteristics section for timing diagrams.
Reading Array Data
The device is automatically set to reading array data after device power-up. No commands are required to retrieve data. The device is ready to read array data after completing an Embedded Program or Embedded Erase algorithm. After the device accepts an Erase Suspend command, the device enters the erase-suspend-read mode, after which the system can read data from any 93

INFORMATION
non-erase-suspended sector. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See the Erase Suspend/Erase Resume Commands section for more information. The system must issue the reset command to return the device to the read (or erase-suspend-read) mode if DQ5 goes high during an active program or erase operation, or if the device is in the autoselect mode. See the next section, Reset Command, for more information. See also Requirements for Reading Array Data in the Device Bus Operations section for more information. The Read-Only Operations table provides the read parameters, and Figure 14 shows the timing diagram.
Autoselect Command Sequence
The autoselect command sequence allows the host system to read several identifier codes at specific addresses:
Identifier Code Manufacturer ID Device ID, Cycle 1 Device ID, Cycle 2 Device ID, Cycle 3 SecSi Sector Factory Protect Sector Protect Verify A7:A0 (x16) 00h 01h 0Eh 0Fh 03h (SA)02h
Note: The device ID is read over three cycles. SA = Sector Address
Reset Command
Writing the reset command resets the device to the read or erase-suspend-read mode. Address bits are don't cares for this command. The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This resets the device to the read mode. Once erasure begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in a program command sequence before programming begins. This resets the device to the read mode. If the program command sequence is written while the device is in the Erase Suspend mode, writing the reset command returns the device to the erase-suspend-read mode. Once programming begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in an autoselect command sequence. Once in the autoselect mode, the reset command must be written to return to the read mode. If the device entered the autoselect mode while in the Erase Suspend mode, writing the reset command returns the device to the erase-suspend-read mode. If DQ5 goes high during a program or erase operation, writing the reset command returns the device to the read mode (or erase-suspend-read mode if the device was in Erase Suspend). Note that if DQ1 goes high during a Write Buffer Programming operation, the system must write the Write-to-Buffer-Abort Reset command sequence to reset the device for the next operation.
Tables 10 and 11 show the address requirements and codes. The autoselect command sequence may be written to an address that is either in the read or erase-suspend-read mode. The autoselect command may not be written while the device is actively programming or erasing. The autoselect command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle that contains the autoselect command. The device then enters the autoselect mode. The system may read at any address any number of times without initiating another autoselect command sequence: The system must write the reset command to return to the read mode (or erase-suspend-read mode if the device was previously in Erase Suspend).
Enter SecSi Sector/Exit SecSi Sector Command Sequence
The SecSi Sector region provides a secured data area containing an 8-word/16-byte random Electronic Serial Number (ESN). The system can access the SecSi Sector region by issuing the three-cycle Enter SecSi Sector command sequence. The device continues to access the SecSi Sector region until the system issues the four-cycle Exit SecSi Sector command sequence. The Exit SecSi Sector command sequence returns the device to normal operation. Tables 10 and 11 show the address and data requirements for both command sequences. See also "SecSi (Secured Silicon) Sector Flash Memory Region" for further information. Note that the ACC function and unlock bypass modes are not available when the SecSi Sector is enabled.
Word Program Command Sequence
Programming is a four-bus-cycle operation. The program command sequence is initiated by writing two unlock write cycles, followed by the program set-up command. The program address and data are written next, which in turn initiate the Embedded Program algorithm. The system is not required to provide further

INFORMATION Write Buffer Programming Write Buffer Programming allows the system write to a maximum of 16 words/32 bytes in one programming operation. This results in faster effective programming time than the standard programming algorithms. The Write Buffer Programming command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the Write Buffer Load command written at the Sector Address in which programming will occur. The fourth cycle writes the sector address and the number of word locations, minus one, to be programmed. For example, if the system will program 6 unique address locations, then 05h should be written to the device. This tells the device how many write buffer addresses will be loaded with data and therefore when to expect the Program Buffer to Flash command. The number of locations to program cannot exceed the size of the write buffer or the operation will abort. The fifth cycle writes the first address location and data to be programmed. The write-buffer-page is selected by address bits AMAX -A 4 . All subsequent add r e s s / d a t a p a i r s m u s t fa l l w i t h i n t h e selected-write-buffer-page. The system then writes the remaining address/data pairs into the write buffer. Write buffer locations may be loaded in any order. The write-buffer-page address must be the same for all address/data pairs loaded into the write buffer. (This means Write Buffer Programming cannot be performed across multiple write-buffer pages. This also means that Write Buffer Programming cannot be performed across multiple sectors. If the system attempts to load programming data outside of the selected write-buffer page, the operation will abort. Note that if a Write Buffer address location is loaded multiple times, the address/data pair counter will be decremented for every data load operation. The host s y s t e m mu s t t h e r e fo r e a c c o u n t for l o a di n g a write-buffer location more than once. The counter decrements for each data load operation, not for each unique write-buffer-address location. Note also that if an address location is loaded more than once into the buffer, the final data loaded for that address will be programmed. Once the specified number of write buffer locations have been loaded, the system must then write the Program Buffer to Flash command at the sector address. Any other address and data combination aborts the Write Buffer Programming operation. The device then begins programming. Data polling should be used while monitoring the last address location loaded into the write buffer. DQ7, DQ6, DQ5, and DQ1 should be monitored to determine the device status during Write Buffer Programming.
controls or timings. The device automatically provides internally generated program pulses and verifies the programmed cell margin. Tables 10 and 11 show the address and data requirements for the word/byte program command sequence, respectively. When the Embedded Program algorithm is complete, the device then returns to the read mode and addresses are no longer latched. The system can determine the status of the program operation by using DQ7 or DQ6. Refer to the Write Operation Status section for information on these status bits. Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a hardware reset immediately terminates the program operation. The program command sequence should be reinitiated once the device has returned to the read mode, to ensure data integrity. Note that the ACC function and unlock bypass modes are not available when the SecSi Sector is enabled. Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from "0" back to a "1." Attempting to do so may cause the device to set DQ5 = 1, or cause the DQ7 and DQ6 status bits to indicate the operation was successful. However, a succeeding read will show that the data is still "0." Only erase operations can convert a "0" to a "1." Unlock Bypass Command Sequence The unlock bypass feature allows the system to program words to the device faster than using the standard program command sequence. The unlock bypass command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. The device then enters the unlock bypass mode. A two-cycle unlock bypass program command sequence is all that is required to program in this mode. The first cycle in this sequence contains the unlock bypass program command, A0h; the second cycle contains the program address and data. Additional data is programmed in the same manner. This mode dispenses with the initial two unlock cycles required in the standard program command sequence, resulting in faster total programming time. Tables 10 and 11 show the requirements for the command sequence. During the unlock bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands are valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock bypass reset command sequence. The first cycle must contain the data 90h. The second cycle must contain the data 00h. The device then returns to the read mode.

INFORMATION command sequence must be written to reset the device for the next operation. Note that the full 3-cycle Write-to-Buffer-Abort Reset command sequence is required when using Write-Buffer-Programming features in Unlock Bypass mode. Accelerated Program The device offers accelerated program operations through the WP#/ACC pin. When the system asserts VHH on the WP#/ACC pin, the device automatically enters the Unlock Bypass mode. The system may then write the two-cycle Unlock Bypass program command sequence. The device uses the higher voltage on the WP#/ACC pin to accelerate the operation. Note that the WP#/ACC pin must not be at VHH for operations other than accelerated programming, or device damage may result. In addition, no external pullup is necessary since the WP#/ACC pin has internal pullup to VCC. Figure 5 illustrates the algorithm for the program operation. Refer to the Erase and Program Operations table in the AC Characteristics section for parameters, and Figure 17 for timing diagrams.
The write-buffer programming operation can be suspended using the standard program suspend/resume commands. Upon successful completion of the Write Buffer Programming operation, the device is ready to execute the next command. The Write Buffer Programming Sequence can be aborted in the following ways: Load a value that is greater than the page buffer size during the Number of Locations to Program step. Write to an address in a sector different than the one specified during the Write-Buffer-Load command. Write an Address/Data pair to a different write-buffer-page than the one selected by the Starting Address during the write buffer data loading stage of the operation. Write data other than the Confirm Command after the specified number of data load cycles.

Data Poll from System
The Program Suspend command allows the system to interrupt a programming operation or a Write to Buffer programming operation so that data can be read from any non-suspended sector. When the Program Suspend command is written during a programming process, the device halts the program operation within 15 s maximum (5 s typical) and updates the status bits. Addresses are not required when writing the Program Suspend command. After the programming operation has been suspended, the system can read array data from any non-suspended sector. The Program Suspend command may also be issued during a programming operation while an erase is suspended. In this case, data may be read from any addresses not in Erase Suspend or Program Suspend. If a read is needed from the SecSi Sector area (One-time Program area), then user must use the proper command sequences to enter and exit this region. Note that the SecSi Sector, autoselect, and CFI functions are unavailable when an program operation is in progress. The system may also write the autoselect command sequence when the device is in the Program Suspend mode. The system can read as many autoselect codes as required. When the device exits the autoselect mode, the device reverts to the Program Suspend mode, and is ready for another valid operation. See Autoselect Command Sequence for more information. After the Program Resume command is written, the device reverts to programming. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard program operation. See Write Operation Status for more information. The system must write the Program Resume command (address bits are don't care) to exit the Program Suspend mode and continue the programming operation. Further writes of the Resume command are ignored. Another Program Suspend command can be written after the device has resume programming.

Sector Erase Command Sequence
Sector erase is a six bus cycle operation. The sector erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock cycles are written, and are then followed by the address of the sector to be erased, and the sector erase command. Tables 10 and 11 show the address and data requirements for the sector erase command sequence. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically programs and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. After the command sequence is written, a sector erase time-out of 50 s occurs. During the time-out period, additional sector addresses and sector erase commands may be written. Loading the sector erase buffer may be done in any sequence, and the number of sectors may be from one sector to all sectors. The time between these additional cycles must be less than 50 s, otherwise erasure may begin. Any sector erase address and command following the exceeded time-out may or may not be accepted. It is recommended that processor interrupts be disabled during this time to ensure all commands are accepted. The interrupts can be re-enabled after the last Sector Erase command is written. Any command other than Sector Erase or Erase Suspend during the time-out period resets the device to the read mode. The system must rewrite the command sequence and any additional addresses and commands. Note that the SecSi Sector, autoselect, and CFI functions are unavailable when an erase operation is in progress.

INFORMATION
The system can monitor DQ3 to determine if the sector erase timer has timed out (See the section on DQ3: Sector Erase Timer.). The time-out begins from the rising edge of the final WE# pulse in the command sequence. When the Embedded Erase algorithm is complete, the device returns to reading array data and addresses are no longer latched. The system can determine the status of the erase operation by reading DQ7, DQ6, or DQ2 in the erasing sector. Refer to the Write Operation Status section for information on these status bits. Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the sector erase command sequence should be reinitiated once the device has returned to reading array data, to ensure data integrity. Figure 7 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters, and Figure 19 section for timing diagrams.
Erase Suspend/Erase Resume Commands
The Erase Suspend command, B0h, allows the system to interrupt a sector erase operation and then read data from, or program data to, any sector not selected for erasure. This command is valid only during the sector erase operation, including the 50 s time-out period during the sector erase command sequence. The Erase Suspend command is ignored if written during the chip erase operation or Embedded Program algorithm. When the Erase Suspend command is written during the sector erase operation, the device requires a maximum of 20 (typical 5 s) to suspend the erase operation. However, when the Erase Suspend command is written during the sector erase time-out, the device immediately terminates the time-out period and suspends the erase operation. After the erase operation has been suspended, the device enters the erase-suspend-read mode. The system can read data from or program data to any sector not selected for erasure. (The device "erase suspends" all sectors selected for erasure.) Reading at any address within erase-suspended sectors produces status information on DQ7-DQ0. The system can use DQ7, or DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. Refer to the Write Operation Status section for information on these status bits. After an erase-suspended program operation is complete, the device returns to the erase-suspend-read mode. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard word program operation. Refer to the Write Operation Status section for more information. In the erase-suspend-read mode, the system can also issue the autoselect command sequence. Refer to the Autoselect Mode and Autoselect Command Sequence sections for details. To resume the sector erase operation, the system must write the Erase Resume command. The address of the erase-suspended sector is required when writing this command. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the chip has resumed erasing.

Valid data on DQ0-DQ7 will appear on successive read cycles. Table 12 shows the outputs for Data# Polling on DQ7. Figure 8 shows the Data# Polling algorithm. Figure 20 in the AC Characteristics section shows the Data# Polling timing diagram.
DQ7: Data# Polling
The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Program or Erase algorithm is in progress or completed, or whether the device is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the command sequence. During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When the Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program address falls within a protected sector, Data# Polling on DQ7 is active for approximately 1 s, then the device returns to the read mode. During the Embedded Erase algorithm, Data# Polling produces a "0" on DQ7. When the Embedded Erase algorithm is complete, or if the device enters the Erase Suspend mode, Data# Polling produces a "1" on DQ7. The system must provide an address within any of the sectors selected for erasure to read valid status information on DQ7. After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling on DQ7 is active for approximately 100 s, then the device returns to the read mode. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. However, if the system reads DQ7 at an address within a protected sector, the status may not be valid. Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with DQ0-DQ6 while Output Enable (OE#) is asserted low. That is, the device may change from providing status information to valid data on DQ7. Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device has completed the program or erase operation and DQ7 has

Notes: 1. VA = Valid address for programming. During a sector erase operation, a valid address is any sector address within the sector being erased. During chip erase, a valid address is any non-protected sector address. 2. DQ7 should be rechecked even if DQ5 = "1" because DQ7 may change simultaneously with DQ5.

INFORMATION After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for approximately 100 s, then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erase-suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6 toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use DQ7 (see the subsection on DQ7: Data# Polling). If a program address falls within a protected sector, DQ6 toggles for approximately 1 s after the program command sequence is written, then returns to reading array data. DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete. Table 12 shows the outputs for Toggle Bit I on DQ6. Figure 9 shows the toggle bit algorithm. Figure 21 in the "AC Characteristics" section shows the toggle bit timing diagrams. Figure 22 shows the differences between DQ2 and DQ6 in graphical form. See also the subsection on DQ2: Toggle Bit II.
RY/BY#: Ready/Busy#
The RY/BY# is a dedicated, open-drain output pin which indicates whether an Embedded Algorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in the command sequence. Since RY/BY# is an open-drain output, several RY/BY# pins can be tied together in parallel with a pull-up resistor to VCC. If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.) If the output is high (Ready), the device is in the read mode, the standby mode, or in the erase-suspend-read mode. Table 12 shows the outputs for RY/BY#.
DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete, or whether the device has entered the Erase Suspend mode. Toggle Bit I may be read at any address, and is valid after the rising edge of the final WE# pulse in the command sequence (prior to the program or erase operation), and during the sector erase time-out. During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. The system may use either OE# or CE# to control the read cycles. When the operation is complete, DQ6 stops toggling.

DQ2: Toggle Bit II
START
Read Byte (DQ7-DQ0) Address =VA Read Byte (DQ7-DQ0) Address =VA
The "Toggle Bit II" on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that is, the Embedded Erase algorithm is in progress), or whether that sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final WE# pulse in the command sequence. DQ2 toggles when the system reads at addresses within those sectors that have been selected for erasure. (The system may use either OE# or CE# to control the read cycles.) But DQ2 cannot distinguish whether the sector is actively erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sector and mode information. Refer to Table 12 to compare outputs for DQ2 and DQ6. Figure 9 shows the toggle bit algorithm in flowchart form, and the section "DQ2: Toggle Bit II" explains the algorithm. See also the RY/BY#: Ready/Busy# subsection. Figure 21 shows the toggle bit timing diagram. Figure 22 shows the differences between DQ2 and DQ6 in graphical form.

Reading Toggle Bits DQ6/DQ2
Refer to Figure 9 for the following discussion. Whenever the system initially begins reading toggle bit status, it must read DQ7-DQ0 at least twice in a row to determine whether a toggle bit is toggling. Typically, the system would note and store the value of the toggle bit after the first read. After the second read, the system would compare the new value of the toggle bit with the first. If the toggle bit is not toggling, the device has completed the program or erase operation. The system can read array data on DQ7-DQ0 on the following read cycle. However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note whether the value of DQ5 is high (see the section on DQ5). If it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5 went high. If the toggle bit is no longer toggling, the device has successfully completed the program or erase operation. If it is still toggling, the device did not completed the operation successfully, and the system must write the reset command to return to reading array data. The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not gone high. The system may continue to monitor the toggle bit and DQ5 through successive read cycles, determining the status as described in the previous paragraph. Alternatively, it may choose to perform
Toggle Bit = Toggle?
No
Yes Program/Erase Operation Not Complete, Write Reset Command Program/Erase Operation Complete
Note: The system should recheck the toggle bit even if DQ5 = "1" because the toggle bit may stop toggling as DQ5 changes to "1." See the subsections on DQ6 and DQ2 for more information.

INFORMATION mand. When the time-out period is complete, DQ3 switches from a "0" to a "1." If the time between additional sector erase commands from the system can be assumed to be less than 50 s, the system need not monitor DQ3. See also the Sector Erase Command Sequence section. After the sector erase command is written, the system should read the status of DQ7 (Data# Polling) or DQ6 (Toggle Bit I) to ensure that the device has accepted the command sequence, and then read DQ3. If DQ3 is "1," the Embedded Erase algorithm has begun; all further commands (except Erase Suspend) are ignored until the erase operation is complete. If DQ3 is "0," the device will accept additional sector erase commands. To ensure the command has been accepted, the system software should check the status of DQ3 prior to and following each subsequent sector erase command. If DQ3 is high on the second status check, the last command might not have been accepted. Table 12 shows the status of DQ3 relative to the other status bits.
other system tasks. In this case, the system must start at the beginning of the algorithm when it returns to determine the status of the operation (top of Figure 9).
DQ5: Exceeded Timing Limits
DQ5 indicates whether the program, erase, or write-to-buffer time has exceeded a specified internal pulse count limit. Under these conditions DQ5 produces a "1," indicating that the program or erase cycle was not successfully completed. The device may output a "1" on DQ5 if the system tries to program a "1" to a location that was previously programmed to "0." Only an erase operation can change a "0" back to a "1." Under this condition, the device halts the operation, and when the timing limit has been exceeded, DQ5 produces a "1." In all these cases, the system must write the reset command to return the device to the reading the array (or to erase-suspend-read if the device was previously in the erase-suspend-program mode).
DQ3: Sector Erase Timer
After writing a sector erase command sequence, the system may read DQ3 to determine whether or not erasure has begun. (The sector erase timer does not apply to the chip erase command.) If additional sectors are selected for erasure, the entire time-out also applies after each additional sector erase com-
DQ1: Write-to-Buffer Abort
DQ1 indicates whether a Write-to-Buffer operation was aborted. Under these conditions DQ1 produces a "1". The system must issue the Write-to-Buffer-Abort-Reset command sequence to return the device to reading array data. See Write Buffer

Notes: 1. Typical program and erase times assume the following conditions: 25C, 3.0 V VCC. Programming specifications assume that all bits are programmed to 00h. 2. Maximum values are measured at VCC = 3.0 V, worst case temperature. Maximum values are valid up to and including 100,000 program/erase cycles. 3. Word programming specification is based upon a single word programming operation not utilizing the write buffer. 4. For 1-16 words programmed in a single write buffer programming operation. 5. Effective write buffer specification is calculated on a per-word basis for a 16-word write buffer operation. 6. In the pre-programming step of the Embedded Erase algorithm, all bits are programmed to 00h before erasure. 7. System-level overhead is the time required to execute the command sequence(s) for the program command. See Tables 12 and 11 for further information on command definitions. 8. The device has a minimum erase and program cycle endurance of 100,000 cycles.
