The device powers on in the read mode. Command sequences are used to place the device in other operation modes such as program and erase. The device has the capability to protect the data in any sector. Once the data protection for a given sector is enabled, the data in that sector cannot be changed using input levels between ground and VCC. The device is segmented into two memory planes. Reads from memory plane B may be performed even while program or erase functions are being executed in memory plane A and vice versa. This operation allows improved system performance by not requiring the system to wait for a program or erase operation to complete before a read is performed. To further increase the flexibility of the device, it
contains an Erase Suspend feature. This feature will put the Erase on hold for any amount of time and let the user read data from or program data to any of the remaining sectors within the same memory plane. There is no reason to suspend the erase operation if the data to be read is in the other memory plane. The end of a program or an Erase cycle is detected by the Ready/Busy pin, Data polling, or by the toggle bit. A V PP pin is provided to improve program/erase times at lower supply voltages. This pin does not need to be utilized. If it is not used the pin should be connected to ground or VCC. To take advantage of faster programming, the pin should supply 5.0 volts during program and erase operations.

AT49BV16X4(T)
A six byte command (bypass unlock) sequence to remove the requirement of entering the three byte program sequence is offered to further improve programming time. After entering the six byte code, only single pulses on the write control lines are required for writing into the device. This mode (single pulse byte/word program) is exited by powering down the device, or by pulsing the RESET pin low and then bringing it back to VCC. Erase and Erase Suspend/Resume commands will not work while in this mode; if entered they will result in data being programmed into the device. It is not recommended that the six byte code reside in the software of the final product but only exist in external programming code. The BYTE pin controls whether the device data I/O pins operate in the byte or word configuration. If the BYTE pin is set at logic "1", the device is in word configuration, I/O0I/O15 are active and controlled by CE and OE. If the BYTE pin is set at logic "0", the device is in byte configuration, and only data I/O pins I/O0-I/O7 are active and controlled by CE and OE. The data I/O pins I/O8-I/O14 are tri-stated, and the I/O15 pin is used as an input for the LSB (A-1) address function.

Device Operation
READ: The AT49BV16X4(T) is accessed like an EPROM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins are asserted on the outputs. The outputs are put in the high impedance state whenever CE or OE is high. This dual-line control gives designers flexibility in preventing bus contention. COMMAND SEQUENCES: When the device is first powered on it will be reset to the read or standby mode depending upon the state of the control line inputs. In order to perform other device functions, a series of command sequences are entered into the device. The command sequences are shown in the Command Definitions table (I/O8 - I/O15 are don't care inputs for the command codes). The command sequences are written by applying a low pulse on the WE or CE input with CE or WE low (respectively) and OE high. The address is latched on the falling edge of CE or WE, whichever occurs last. The data is latched by the first rising edge of CE or WE. Standard microprocessor write timings are used. The address locations used in the command sequences are not affected by entering the command sequences.

RESET: A RESET input pin is provided to ease some system applications. When RESET is at a logic high level, the device is in its standard operating mode. A low level on the RESET input halts the present device operation and puts the outputs of the device in a high impedance state. When a high level is reasserted on the RESET pin, the device returns to the Read or Standby mode, depending upon the state of the control inputs. By applying a 12V 0.5V input signal to the RESET pin any sector can be reprogrammed even if the sector lockout feature has been enabled (see Sector Programming Lockout Override section). ERASURE: Before a byte/word can be reprogrammed, it must be erased. The erased state of memory bits is a logical "1". The entire device can be erased by using the Chip Erase command or individual sectors can be erased by using the Sector Erase commands. CHIP ERASE: The entire device can be erased at one time by using the 6-byte chip erase software code. After the chip erase has been initiated, the device will internally time the erase operation so that no external clocks are required. The maximum time to erase the chip is tEC. If the sector lockout has been enabled, the Chip Erase will not erase the data in the sector that has been locked; it will erase only the unprotected sectors. After the chip erase, the device will return to the read or standby mode. SECTOR ERASE: As an alternative to a full chip erase, the device is organized into forty sectors (SA0 - SA39) that can be individually erased. The Sector Erase command is a six bus cycle operation. The sector address is latched on the falling WE edge of the sixth cycle while the 30H data input command is latched on the rising edge of WE. The sector erase starts after the rising edge of WE of the sixth cycle. The erase operation is internally controlled; it will automatically time to completion. The maximum time to erase a section is tSEC. When the sector programming lockout feature is not enabled, the sector will erase (from the same sector erase command). Once a sector has been protected, data in the protected sectors cannot be changed unless the RESET pin is taken to 12V 0.5V. An attempt to erase a sector that has been protected will result in the operation terminating in 2 s. BYTE/WORD PROGRAMMING: Once a memory block is erased, it is programmed (to a logical "0") on a byte-by-byte or on a word-by-word basis. Programming is accomplished via the internal device command register and is a 4-bus cycle operation. The device will automatically generate the required internal program pulses. Any commands written to the chip during the embedded programming cycle will be ignored. If a hardware reset happens during programming, the data at the location being programmed will be corrupted. Please note that a data "0" cannot be programmed back to a "1"; only erase operations can convert "0"s to "1"s. Programming is completed after
the specified tBP cycle time. The DATA polling feature or the toggle bit feature may be used to indicate the end of a program cycle. SECTOR PROGRAMMING LOCKOUT: Each sector has a programming lockout feature. This feature prevents programming of data in the designated sectors once the feature has been enabled. These sectors can contain secure code that is used to bring up the system. Enabling the lockout feature will allow the boot code to stay in the device while data in the rest of the device is updated. This feature does not have to be activated; any sector's usage as a write protected region is optional to the user. Once the feature is enabled, the data in the protected sectors can no longer be erased or programmed when input levels of 5.5V or less are used. Data in the remaining sectors can still be changed through the regular programming method. To activate the lockout feature, a series of six program commands to specific addresses with specific data must be performed. Please refer to the Command Definitions table. SECTOR PROGRAMMING LOCKOUT OVERRIDE: The user can override the sector programming lockout by taking the RESET pin to 12V 0.5V. By doing this protected data can be altered through a chip erase, sector erase or byte/word programming. When the RESET pin is brought back to TTL levels the sector programming lockout feature is again active. ERASE SUSPEND/ERASE RESUME: The erase suspend command allows the system to interrupt a sector erase operation and then program or read data from a different sector within the same plane. Since this device has a dual plane architecture, there is no need to use the erase suspend feature while erasing a sector when you want to read data from a sector in the other plane. After the erase suspend command is given, the device requires a maximum time of 15 s to suspend the erase operation. After the erase operation has been suspended, the plane which contains the suspended sector enters the erase-suspend-read mode. The system can then read data or program data to any other sector within the device. An address is not required during the erase suspend command. During a sector erase suspend, another sector cannot be erased. To resume the sector erase operation, the system must write the erase resume command. The erase resume command is a one bus cycle command, which does require the plane address (determined by A18 and A19). The device also supports an erase suspend during a complete chip erase. While the chip erase is suspended, the user can read from any sector within the memory that is protected. The command sequence for a chip erase suspend and a sector erase suspend are the same. PRODUCT IDENTIFICATION: The product identification mode identifies the device and manufacturer as Atmel. It

may be accessed by hardware or software operation. The hardware operation mode can be used by an external programmer to identify the correct programming algorithm for the Atmel product. For details, see Operating Modes (for hardware operation) or Software Product Identification. The manufacturer and device code is the same for both modes. DATA POLLING: The AT49BV16X4(T) features DATA polling to indicate the end of a program cycle. During a program cycle an attempted read of the last byte/word loaded will result in the complement of the loaded data on I/O7. Once the program cycle has been completed, true data is valid on all outputs and the next cycle may begin. During a chip or sector erase operation, an attempt to read the device will give a "0" on I/O7. Once the program or erase cycle has completed, true data will be read from the device. DATA polling may begin at any time during the program cycle. Please see "Status Bit Table" for more details. TOGGLE BIT: In addition to DATA polling the AT49BV16X4(T) provides another method for determining the end of a program or erase cycle. During a program or erase operation, successive attempts to read data from the same memory plane will result in I/O6 toggling between one and zero. Once the program cycle has completed, I/O6 will stop toggling and valid data will be read. Examining the toggle bit may begin at any time during a program cycle. An additional toggle bit is available on I/O2 which can be used in conjunction with the toggle bit which is available on I/O6. While a sector is erase suspended, a read or a program operation from the suspended sector will result in the I/O2 bit toggling. Please see status bit table for more details. RDY/BUSY: An open drain READY/BUSY output pin provides another method of detecting the end of a program or erase operation. RDY/BUSY is actively pulled low during the internal program and erase cycles and is released at the completion of the cycle. The open drain connection allows for OR-tying of several devices to the same RDY/BUSY line. HARDWARE DATA PROTECTION: Hardware features protect against inadvertent programs to the AT49BV16X4(T) in the following ways: (a) V CC sense: if VCC is below 1.8V (typical), the program function is inhibited. (b) VCC power on delay: once VCC has reached the VCC sense level, the device will automatically time out 10 ms (typical) before programming. (c) Program inhibit: holding any one of OE low, CE high or WE high inhibits program cycles. (d) Noise filter: pulses of less than 15 ns (typical) on the WE or CE inputs will not initiate a program cycle. INPUT LEVELS: While operating with a 2.7V to 3.6V power supply, the address inputs and control inputs (OE, CE, and WE) may be driven from 0 to 5.5V without adversely affecting the operation of the device. The I/O lines can only be driven from 0 to VCC + 0.6V. OUTPUT LEVELS: Output High Levels (VOH) are equal to VCCQ - 0.2V (not VCC). For 2.7V - 3.6V output levels, VCCQ must be tied to V CC. For 1.8V - 2.2V output levels, V CCQ must be regulated to 2.0V 10% while VCC must be regulated to 2.7V - 3.0V (for minimum power).

CE may be delayed up to tACC - tCE after the address transition without impact on tACC. OE may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE or by tACC - tOE after an address change without impact on tACC. tDF is specified from OE or CE whichever occurs first (CL = 5 pF). This parameter is characterized and is not 100% tested.
