GENERAL DESCRIPTION
The K5A3x80YT(B)C featuring single 3.0V power supply is a Multi Chip Package Memory which combines 32Mbit Dual Bank Flash and 8Mbit fCMOS SRAM. The 32Mbit Flash memory is organized as 4M x8 or 2M x16 bit and 8Mbit SRAM is organized as 1M x8 or 512K x16 bit. The memory architecture of flash memory is designed to divide its memory arrays into 71 blocks and this provides highly flexible erase and program capability. This device is capable of reading data from one bank while programming or erasing in the other bank with dual bank organization. The Flash memory performs a program operation in units of 8 bits (Byte) or 16 bits (Word) and erases in units of a block. Single or multiple blocks can be erased. The block erase operation is completed for typically 0.7sec. The 8Mbit SRAM supports low data retention voltage for battery backup operation with low data retention current. The K5A3x80YT(B)C is suitable for the memory of mobile communication system to reduce mount area. This device is available in 69-ball TBGA Type package.

Flash MEMORY COMMAND DEFINITIONS
Preliminary MCP MEMORY
Flash memory operates by selecting and executing its operational modes. Each operational mode has its own command set. In order to select a certain mode, a proper command with specific address and data sequences must be written into the command register. Writing incorrect information which include address and data or writing an improper command will reset the device to the read mode. The defined valid register command sequences are stated in Table 5. Note that Erase Suspend (B0H) and Erase Resume (30H) commands are valid only while the Block Erase Operation is in progress.

Flash DEVICE OPERATION Byte/Word Mode
Preliminary MCP MEMORY
If the BYTEF ball is set at logical "1" , the device is in word mode, DQ0-DQ15 are active. Otherwise the BYTEF ball is set at logical "0" , the device is in byte mode, DQ0-DQ7 are active. DQ8-DQ14 are in the High-Z state and DQ15 ball is used as an input for the LSB (A-1) address ball.
Read Mode
Flash memory is controlled by Chip Enable (CEF), Output Enable (OE) and Write Enable (WE). When CEF and OE are low and WE is high, the data stored at the specified address location,will be the output of the device. The outputs are in high impedance state whenever CEF or OE is high.
Standby Mode
Flash memory features Stand-by Mode to reduce power consumption. This mode puts the device on hold when the device is deselected by making CEF high (CEF = VIH). Refer to the DC characteristics for more details on stand-by modes.
Output Disable
The device outputs are disabled when OE is High (OE = VIH). The output balls are in high impedance state.
Automatic Sleep Mode
Flash memory features Automatic Sleep Mode to minimize the device power consumption. Since the device typically draws 5A of current in Automatic Sleep Mode, this feature plays an extremely important role in battery-powered applications. When addresses remain steady for tAA+50ns, the device automatically activates the Automatic Sleep Mode. In the sleep mode, output data is latched and always available to the system. When addresses are changed, the device provides new data without wait time.

Figure 2. Auto Sleep Mode Operation Autoselect Mode
Flash memory offers the Autoselect Mode to identify manufacturer and device type by reading a binary code. The Autoselect Mode allows programming equipment to automatically match the device to be programmed with its corresponding programming algorithm. In addition, this mode allows the verification of the status of write protected blocks. The manufacturer and device code can be read via the command register. The Command Sequence is shown in Table 5 and Figure 3. The autoselect operation of block protect verification is initiated by first writing two unlock cycle. The third cycle must contain the bank address and autoselect command (90H). If Block address while (A6, A1, A0) = (0,1,0) is finally asserted on the address ball, it will produce a logical "1" at the device output DQ0 to indicate a write protected block or a logical "0" at the device output DQ0 to indicate a write unprotected block. To terminate the autoselect operation, write Reset command (F0H) into the command register.

Figure 3. Autoselect Operation Write (Program/Erase) Mode
Flash memory executes its program/erase operations by writing commands into the command register. In order to write the commands to the register, CEF and WE must be low and OE must be high. Addresses are latched on the falling edge of CEF or WE (whichever occurs last) and the data are latched on the rising edge of CEF or WE (whichever occurs first). The device uses standard microprocessor write timing.
Program
Flash memory can be programmed in units of a word or a byte. Programming is writing 0's into the memory array by executing the Internal Program Routine. In order to perform the Internal Program Routine, a four-cycle command sequence is necessary. The first two cycles are unlock cycles. The third cycle is assigned for the program setup command. In the last cycle, the address of the memory location and the data to be programmed at that location are written. The device automatically generates adequate program pulses and verifies the programmed cell margin by the Internal Program Routine. During the execution of the Routine, the system is not required to provide further controls or timings. During the Internal Program Routine, commands written to the device will be ignored. Note that a hardware reset during a program operation will cause data corruption at the corresponding location.

Unlock Bypass
Preliminary MCP MEMORY
Flash memory provides the unlock bypass mode to save its program time. The mode is invoked by the unlock bypass command sequence. Unlike the standard program command sequence that contains four bus cycles, the unlock bypass program command sequence comprises only two bus cycles. The unlock bypass mode is engaged by issuing the unlock bypass command sequence which is comprised of three bus cycles. Writing first two unlock cycles is followed by a third cycle containing the unlock bypass command (20H). Once the device is in the unlock bypass mode, the unlock bypass program command sequence is necessary to program in this mode. The unlock bypass program command sequence is comprised of only two bus cycles; writing the unlock bypass program command (A0H) is followed by the program address and data. This command sequence is the only valid one for programming the device in the unlock bypass mode. The unlock bypass reset command sequence is the only valid command sequence to exit the unlock bypass mode. The unlock bypass reset command sequence consists of two bus cycles. The first cycle must contain the data (90H). The second cycle contains only the data (00H). Then, the device returns to the read mode
Chip Erase
To erase a chip is to write 1s into the entire memory array by executing the Internal Erase Routine. The Chip Erase requires six bus cycles to write the command sequence. The erase set-up command is written after first two "unlock" cycles. Then, there are two more write cycles prior to writing the chip erase command. The Internal Erase Routine automatically pre-programs and verifies the entire memory for an all zero data pattern prior to erasing. The automatic erase begins on the rising edge of the last WE or CEF pulse in the command sequence and terminates when DQ7 is "1". After that the device returns to the read mode.

Block Erase
To erase a block is to write 1s into the desired memory block by executing the Internal Erase Routine. The Block Erase requires six bus cycles to write the command sequence shown in Table 5. After the first two "unlock" cycles, the erase setup command (80H) is written at the third cycle. Then there are two more "unlock" cycles followed by the Block Erase command. The Internal Erase Routine automatically pre-programs and verifies the entire memory prior to erasing it. The block address is latched on the falling edge of WE or CEF, while the Block Erase command is latched on the rising edge of WE or CEF. Multiple blocks can be erased sequentially by writing the six bus-cycle operation in Fig 6. Upon completion of the last cycle for the Block Erase, additional block address and the Block Erase command (30H) can be written to perform the Multi-Block Erase. An 50us (typical) "time window" is required between the Block Erase command writes. The Block Erase command must be written within the 50us "time window", otherwise the Block Erase command will be ignored. The 50us "time window" is reset when the falling edge of the WE occurs within the 50us of "time window" to latch the Block Erase command. During the 50us of "time window", any command other than the Block Erase or the Erase Suspend command written to the device will reset the device to read mode. After the 50 us of "time window", the Block Erase command will initiate the Internal Erase Routine to erase the selected blocks. Any Block Erase address and command following the exceeded "time window" may or may not be accepted. No other commands will be recognized except the Erase Suspend command.

The Erase Suspend command interrupts the Block Erase to read or program data in a block that is not being erased. The Erase Suspend command is only valid during the Block Erase operation including the time window of 50 us. The Erase Suspend command is not valid while the Chip Erase or the Internal Program Routine sequence is running. When the Erase Suspend command is written during a Block Erase operation, the device requires a maximum of 20 us to suspend the erase operation. But, when the Erase Suspend command is written during the block erase time window (50 us) , the device immediately terminates the block erase time window and suspends the erase operation. After the erase operation has been suspended, the device is availble for reading or programming data in a block that is not being erased. The system may also write the autoselect command sequence when the device is in the Erase Suspend mode. When the Erase Resume command is executed, the Block Erase operation will resume. When the Erase Suspend or Erase Resume command is executed, the addresses are in Don't Care state.

Read While Write
Preliminary MCP MEMORY
Flash memory provides dual bank memory architecture that divides the memory array into two banks. The device is capable of reading data from one bank and writing data to the other bank simultaneously. This is so called the Read While Write operation with dual bank architecture; this feature provides the capability of executing the read operation during Program/Erase or Erase-Suspend-Program operation. The Read While Write operation is prohibited during the chip erase operation. It is also allowed during erase operation when either single block or multiple blocks from same bank are loaded to be erased. It means that the Read While Write operation is prohibited when blocks from Bank1 and another blocks from Bank2 are loaded all together for the multi-block erase operation.
Block Group Protection & Unprotection
Flash memory feature hardware block group protection. This feature will disable both program and erase operations in any combination of twenty five block groups of memory. Please refer to Tables 10 and 11. The block group protection feature is enabled using programming equipment at the user' site. The device is shipped with all block groups unprotected. s This feature can be hardware protected or unprotected. If a block is protected, program or erase command in the protected block will be ignored by the device. The protected block can only be read. This is useful method to preserve an important program data. The block group unprotection allows the protected blocks to be erased or programed. All blocks must be protected before unprotect operation is executing. The block protection and unprotection can be implemented by the following method.

Address must be inputted to the block group address (A12~A20) during block group protection operation. Please refer to Figure 9 (Algorithm) and Switching Waveforms of Block Group Protect & Unprotect Operations.
Temporary Block Group Unprotect
The protected blocks of the Flash memory can be temporarily unprotected by applying high voltage (VID = 8.5V~12.5V) to the RESET ball. In this mode, previously protected blocks can be programmed or erased with the program or erase command routines. When the RESET ball goes high (RESET = VIH), all the previously protected blocks will be protected again. If the WP/ACC ball is asserted at VIL , the two outermost boot blocks remain protected.

Write Protect (WP)
Preliminary MCP MEMORY
The WP/ACC ball has two useful functions. The one is that certain boot block is protected by the hardware method not to use VID. The other is that program operation is accelerated to reduce the program time (Refer to Accelerated program Operation Paragraph). When the WP/ACC ball is asserted at VIL, the device can not perform program and erase operation in the two "outermost" 8K byte boot blocks independently of whether those blocks were protected or unprotected using the method described in "Block Group protection/Unprotection". The write protected blocks can only be read. This is useful method to preserve an important program data. The two outermost 8K byte boot blocks are the two blocks containing the lowest addresses in a bottom-boot-configured device, or the two blocks containing the highest addresses in a top-boot-congfigured device. (K5A3280YT/K5A3380YT : BA69 and BA70, K5A3280YB/K5A3380YB : BA0 and BA1) When the WP/ACC ball is asserted at VIH, the device reverts to whether the two outermost 8K byte boot blocks were last set to be protected or unprotected. That is, block protection or unprotection for these two blocks depends on whether they were last protected or unprotected using the method described in "Block Group protection/unprotection". Recommend that the WP/ACC ball must not be in the state of floating or unconnected, or the device may be led to malfunction.
Secode(Security Code) Block Region
The Secode Block feature provides a Flash memory region to be stored unique and permanent identification code, that is, Electronic Serial Number (ESN), customer code and so on. This is primarily intended for customers who wish to use an Electronic Serial Number (ESN) in the device with the ESN protected against modification. Once the Secode Block region is protected, any further modification of that region is impossible. This ensures the security of the ESN once the product is shipped to the field. The Secode Block is factory locked or customer lockable. Before the device is shipped, the factory locked Secode Block is written on the special code and it is protected. The Secode Indicator bit (DQ7) is permanently fixed at "1" and it is not changed. The customer lockable Secode Block is unprotected, therefore it is programmed and erased. The Secode Indicator bit (DQ7) of it is permanently fixed at "0" and it is not changed. But once it is protected, there is no procedure to unprotect and modify the Secode Block. The Secode Block region is 64K bytes in length and is accessed through a new command sequence (see Table 5). After the system has written the Enter Secode Block command sequence, the system may read the Secode Block region by using the same addresses of the boot blocks (8KBx8). The K5A3280YT/K5A3380YT occupies the address of the byte mode 3F0000H to 3FFFFFH (word mode 1F8000H to 1FFFFFH) and the K5A3280YB/K5A3380YB type occupies the address of the byte mode 000000H to 00FFFFH (word mode 000000H to 007FFFH). This mode of operation continues until the system issues the Exit Secode Block command sequence, or until power is removed from the device. On power-up, or following a hardware reset, the device reverts to read mode.
Accelerated Program Operation
Accelerated program operation reduces the program time. This is one of two functions provided by the WP/ACC ball. When the WP/ ACC ball is asserted as VHH, the device automatically enters the aforementioned Unlock Bypass mode, temporarily unprotecting any protected blocks, and reduces the program operation time. The system would use a two-cycle program command sequence as required by the Unlock Bypass mode. Removing VHH from the WP/ACC ball returns the device to normal operation. Recommend that the WP/ACC ball must not be asserted at VHH except accelerated program operation, or the device may be damaged. In addition, the WP/ACC ball must not be in the state of floating or unconnected, otherwise the device may be led to malfunction.
Software Reset
The reset command provides that the device is reseted to read mode or erase-suspend-read mode. The addresses are in Don't Care state. The reset command is vaild between the sequence cycles in an erase command sequence before erasing begins, or in a program command sequence before programming begins. This resets the bank in which was operating to read mode. if the device is be erasing or programming, the reset command is invalid until the operation is completed. Also, the reset command is valid between the sequence cycles in an autoselect command sequence. In the autoselect mode, the reset command returns the bank to read mode. If a bank entered the autoselect mode in the Erase Suspend mode, the reset command returns the bank to erase-suspend-read mode. If DQ5 is high on erase or program operation, the reset command return the bank to read mode or erase-suspend-read mode if the bank was in the Erase Suspend state.

Hardware Reset
Preliminary MCP MEMORY
Flash memory offers a reset feature by driving the RESET ball to VIL. The RESET ball must be kept low (VIL) for at least 500ns. When the RESET ball is driven low, any operation in progress will be terminated and the internal state machine will be reset to the standby mode after 20us. If a hardware reset occurs during a program operation, the data at that particular location will be lost. Once the RESET ball is taken high, the device requires 200ns of wake-up time until outputs are valid for read access. Also, note that all the data output balls are tri-stated for the duration of the RESET pulse. The RESET ball may be tied to the system reset ball. If a system reset occurs during the Internal Program and Erase Routine, the device will be automatically reset to the read mode ; this will enable the systems microprocessor to read the boot-up firmware from the Flash memory.
Power-up Protection
To avoid initiation of a write cycle during VccF Power-up, RESET low must be asserted during power-up. After RESET goes high, the device is reset to the read mode.
Low VccF Write Inhibit
To avoid initiation of a write cycle during VccF power-up and power-down, a write cycle is locked out for VccF less than 1.8V. If VccF < VLKO (Lock-Out Voltage), the command register and all internal program/erase circuits are disabled. Under this condition the device will reset itself to the read mode. Subsequent writes will be ignored until the VccF level is greater than VLKO. It is the users responsibility to ensure that the control balls are logically correct to prevent unintentional writes when VccF is above 1.8V.
Write Pulse Glitch Protection
Noise pulses of less than 5ns(typical) on CEF, OE, or WE will not initiate a write cycle.
Logical Inhibit
Writing is inhibited under any one of the following conditions : OE = VIL, CEF = VIH or WE = VIH. To initiate a write, CEF and WE must be "0", while OE is "1".
Commom Flash Memory Interface
Common Flash Momory Interface is contrived to increase the compatibility of host system software. It provides the specific information of the device, such as memory size, byte/word configuration, and electrical features. Once this information has been obtained, the system software will know which command sets to use to enable flash writes, block erases, and control the flash component. When the system writes the CFI command(98H) to address 55H in word mode(or address AAH in byte mode), the device enters the CFI mode. And then if the system writes the address shown in Table 12, the system can read the CFI data. Query data are always presented on the lowest-order data outputs(DQ0-7) only. In word(x16) mode, the upper data outputs(DQ8-15) is 00h. To terminate this operation, the system must write the reset command.

DEVICE STATUS FLAGS
Preliminary MCP MEMORY
Flash memory has means to indicate its status of operation in the bank where a program or erase operation is in processes. Address must include bank address being excuted internal routine operation. The status is indicated by raising the device status flag via corresponding DQ balls or the RY/ BY ball. The corresponding DQ balls are DQ7, DQ6, DQ5, DQ3 and DQ2. The status is as follows :
Table 13. Hardware Sequence Flags

DQ2

RY/BY

NOTES: 1. DQ2 will toggle when the device performs successive read operations from the erase suspended block. 2. If DQ5 is High (exceeded timing limits), successive reads from a problem block will cause DQ2 to toggle.
DQ7 : Data Polling
When an attempt to read the device is made while executing the Internal Program, the complement of the data is written to DQ7 as an indication of the Routine in progress. When the Routine is completed an attempt to access to the device will produce the true data written to DQ7. When a user attempts to read the device during the Erase operation, DQ7 will be low. If the device is placed in the Erase Suspend Mode, the status can be detected via the DQ7 ball. If the system tries to read an address which belongs to a block that is being erased, DQ7 will be high. If a non-erased block address is read, the device will produce the true data to DQ7. If an attempt is made to program a protected block, DQ7 outputs complements the data for approximately 1s and the device then returns to the Read Mode without changing data in the block. If an attempt is made to erase a protected block, DQ7 outputs complement data in approximately 100us and the device then returns to the Read Mode without erasing the data in the block.
DQ6 : Toggle Bit
Toggle bit is another option to detect whether an Internal Routine is in progress or completed. Once the device is at a busy state, DQ6 will toggle. Toggling DQ6 will stop after the device completes its Internal Routine. If the device is in the Erase Suspend Mode, an attempt to read an address that belongs to a block that is being erased will produce a high output of DQ6. If an address belongs to a block that is not being erased, toggling is halted and valid data is produced at DQ6. If an attempt is made to program a protected block, DQ6 toggles for approximately 1us and the device then returns to the Read Mode without changing the data in the block. If an attempt is made to erase a protected block, DQ6 toggles for approximately 100s and the device then returns to the Read Mode without erasing the data in the block.
DQ5 : Exceed Timing Limits
If the Internal Program/Erase Routine extends beyond the timing limits, DQ5 will go High, indicating program/erase failure.

K5A3x80YT(B)C
DQ3 : Block Erase Timer
Preliminary MCP MEMORY
The status of the multi-block erase operation can be detected via the DQ3 ball. DQ3 will go High if 50s of the block erase time window expires. In this case, the Internal Erase Routine will initiate the erase operation.Therefore, the device will not accept further write commands until the erase operation is completed. DQ3 is Low if the block erase time window is not expired. Within the block erase time window, an additional block erase command (30H) can be accepted. To confirm that the block erase command has been accepted, the software may check the status of DQ3 following each block erase command.
DQ2 : Toggle Bit 2
The device generates a toggling pulse in DQ2 only if an Internal Erase Routine or an Erase Suspend is in progress. When the device executes the Internal Erase Routine, DQ2 toggles only if an erasing block is read. Although the Internal Erase Routine is in the Exceeded Time Limits, DQ2 toggles only if an erasing block in the Exceeded Time Limits is read. When the device is in the Erase Suspend mode, DQ2 toggles only if an address in the erasing block is read. If a non-erasing block address is read during the Erase Suspend mode, then DQ2 will produce valid data. DQ2 will go High if the user tries to program a non-erase suspend block while the device is in the Erase Suspend mode. Combination of the status in DQ6 and DQ2 can be used to distinguish the erase operation from the program operation.
RY/BY : Ready/Busy
Flash memory has a Ready / Busy output that indicates either the completion of an operation or the status of Internal Algorithms. If the output is Low, the device is busy with either a program or an erase operation. If the output is High, the device is ready to accept any read/write or erase operation. When the RY/ BY ball is low, the device will not accept any additional program or erase commands with the exception of the Erase Suspend command. If Flash memory is placed in an Erase Suspend mode, the RY/ BY output will be High. For programming, the RY/ BY is valid (RY/ BY = 0) after the rising edge of the fourth WE pulse in the four write pulse sequence. For Chip Erase, RY/ BY is also valid after the rising edge of WE pulse in the six write pulse sequence. For Block Erase, RY/ BY is also valid after the rising edge of the sixth WE pulse. The ball is an open drain output, allowing two or more Ready/ Busy outputs to be OR-tied. An appropriate pull-up resistor is required for proper operation.

High-Z
1. A write occurs during the overlap(tWP) of low CS1S and low WE. A write begins when CS1S goes low and WE goes low with asserting UB or LB for single byte operation or simultaneously asserting UB and LB for double byte operation. A write ends at the earliest transition when CS1S goes high and WE goes high. The tWP is measured from the beginning of write to the end of write. 2. tCW is measured from the CS1S going low to the end of write. 3. tAS is measured from the address valid to the beginning of write. 4. tWR is measured from the end of write to the address change. tWR applied in case a write ends as CS1S or WE going high.
