SUMMARY DESCRIPTION The M59PW1282 is a 128Mbit (8Mb x16), MaskROM pinout compatible, non-volatile LightFlashTM memory, that can be read, erased and reprogrammed. Read operations can be performed using a single low voltage (2.7 to 3.6V) supply. Program and Erase operations require an additional VPP (11.4 to 12.6V) power supply. On power-up the memory defaults to its Read mode where it can be read in the same way as a ROM or EPROM. The Mask-ROM compatibility is obtained using a dual function Address/Voltage Supply pin (A22/ VPP). In Read mode the A22/VPP pin works as an address pin; in Program or Erase mode it also works as a voltage supply pin. At the beginning of any program or erase operation, a specific procedure (see Figure 4) must be performed to internally memorize the A22 value that will be used during the program or erase operation. The device is composed of two 64Mbit memories stacked in a single package. Recommended operating conditions do not allow both memories to be active at the same time. Address A22 selects the memory to be enabled. The other memory is in Standby mode. The memory is divided into 64 uniform blocks that can be erased independently so it is possible to
preserve valid data while old data is erased. Program and Erase commands are written to the Command Interface of the memory. An on-chip Program/Erase Controller (P/E.C.) simplifies the process of programming or erasing the memory by taking care of all of the special operations that are required to update the memory contents. The M59PW1282 features an innovative command, Multiple Word Program, that is used to program large streams of data. It greatly reduces the total programming time when a large number of Words are written to the memory at any one time. Using this command the entire memory can be programmed in 16s, compared to 72s using the standard Word Program. The end of a Program or Erase operation can be detected and any error conditions identified. The command set required to control the memory is consistent with JEDEC standards. Chip Enable and Output Enable signals control the bus operation of the memory. They allow simple connection to most microprocessors, often without additional logic. The memory is offered in SO44 package and is supplied with all the bits set to '1').

SIGNAL DESCRIPTIONS See Figure 2, Logic Diagram, and Table 1, Signal Names, for a brief overview of the signals connected to this device. Address Inputs (A0-A21). The Address Inputs select the cells in the memory array to access during Bus Read operations. During Bus Write operations they control the commands sent to the Command Interface of the Program/Erase Controller. Address/Voltage Supply (A22/V PP ). The A22/VPP signal has two functions. During read operations the A22/VPP signal works as an address input, which is used to select the Top (A22 = VIH) or Bottom (A22 = VIL) die. During program or erase operations it also works as a VPP voltage supply pin. At the beginning of any program or erase operation, a specific procedure (see Figure 4) must be performed to internally memorize the A22 value that will be used during the program or erase operation. When the VPP is in the VHH range (see Table 12, DC Characteristic, for the relevant values) program and erase operations are enabled. During such operations VPP must be stable in the VHH range. Program and erase operation are not allowed when VPP is below the VHH range. Data Inputs/Outputs (DQ0-DQ7). The Data Inputs/Outputs output the data stored at the selected address during a Bus Read operation. During Bus
Write operations they represent the command sent to the Command Interface of the Program/ Erase Controller. When reading the Status Register they report the status of the ongoing algorithm. Data Inputs/Outputs (DQ8-DQ15). The Data Inputs/Outputs output the data stored at the selected address during a Bus Read operation. During Bus Write operations the Command Interface does not use these bits. When reading the Status Register these bits should be ignored. Chip Enable (E). The Chip Enable, E, activates the memory, allowing Bus Read operations to be performed. It also controls the Bus Write operations, when VPP is in the VHH range. Output Enable (G). The Output Enable, G, controls the Bus Read operations of the memory. It also allows Bus Write operations, when VPP is in the VHH range. VCC Supply Voltage. The VCC Supply Voltage supplies the power for Read operations. A 0.1F capacitor should be connected between the VCC Supply Voltage pin and the VSS Ground pin to decouple the current surges from the power supply. The PCB track widths must be sufficient to carry the currents required during program operations, ICC3. Vss Ground. The VSS Ground is the reference for all voltage measurements.

BUS OPERATIONS There are six standard bus operations that control the device. These are Bus Read, Bus Write, Output Disable, Standby, Automatic Standby and Electronic Signature. See Tables 3, Bus Operations, for a summary. Typically glitches of less than 5ns on Chip Enable or Write Enable are ignored by the memory and do not affect bus operations. Bus Read. Bus Read operations read from the memory cells, or specific registers in the Command Interface. A valid Bus Read operation involves setting the desired address on the Address Inputs and applying a Low signal, VIL, to Chip Enable and Output Enable. The Data Inputs/Outputs will output the value, see Figure 12, Read AC Waveforms, and Table 12, Read AC Characteristics, for details of when the output becomes valid. During read array operations A22 selects Top (A22 = VIH) or Bottom (A22 = VIL) die. Bus Write. Bus Write operations write to the Command Interface. Bus Write is enabled only when VPP is set to VHH. A valid Bus Write operation begins by setting the desired address on the Address Inputs. The Address Inputs are latched by the Command Interface on the falling edge of Chip Enable. The Data Inputs/Outputs are latched by the Command Interface on the rising edge of Chip Enable. Output Enable must remain High, VIH, during the whole Bus Write operation. See Figure 12, Write AC Waveforms, and Table 14, Write AC Table 3. Bus Operations

Characteristics, for details of the timing requirements. Output Disable. The Data Inputs/Outputs are in the high impedance state when Output Enable is High, VIH. Standby. When Chip Enable is High, VIH, the memory enters Standby mode and the Data Inputs/Outputs pins are placed in the high-impedance state. To reduce the Supply Current to the Standby Supply Current, ICC2, Chip Enable should be held within VCC 0.2V. For the Standby current level see Table 12, DC Characteristics. During program operation the memory will continue to use the Program Supply Current, ICC3, for Program operation until the operation completes. Automatic Standby. If CMOS levels (VCC 0.2V) are used to drive the bus and the bus is inactive for 150ns or more the memory enters Automatic Standby where the internal Supply Current is reduced to the Standby Supply Current, ICC2. The Data Inputs/Outputs will still output data if a Bus Read operation is in progress. Electronic Signature. The memory has two codes, the manufacturer code and the device code, that can be read to identify the memory. These codes can be read by applying the signals listed in Tables 3, Bus Operations, once the Auto Select Command is executed. To exit Electronic Signature mode, the Read/Reset command must be issued.

COMMAND INTERFACE All Bus Write operations to the memory are interpreted by the Command Interface. Commands consist of one or more sequential Bus Write operations. Failure to observe a valid sequence of Bus Write operations will result in the memory returning to Read mode. The long command sequences are imposed to maximize data security. Refer to Tables 4 and 5, for a summary of the commands. As the device contains two internal memories care must be taken to issue the commands to the correct address. To select the Top die (A22 = VIH) or the Bottom die (A22 = VIL) the A22 latch procedure (see Figure 4) must be followed. It is not necessary to repeat the A22 latch procedure if all the commands are issued to the same die, unless the power supply VCC is switched off. Read/Reset Command. The Read/Reset command returns the memory to its Read mode where it behaves like a ROM or EPROM, unless otherwise stated. It also resets the errors in the Status Register. Either one or three Bus Write operations can be used to issue the Read/Reset command. VPP must be set to VHH during the Read/Reset command. If VPP is set to either VIL or VIH the command will be ignored. The command can be issued, between Bus Write cycles before the start of a program operation, to return the device to read mode. Once the program operation has started the Read/Reset command is no longer accepted. Auto Select Command. The Auto Select command is used to read the Manufacturer Code and the Device Code. VPP must be set to VHH during the Auto Select command. If VPP is set to either VIL or VIH the command will be ignored. Three consecutive Bus Write operations are required to issue the Auto Select command. Once the Auto Select command is issued the memory remains in Auto Select mode until a Read/Reset command is issued, all other commands are ignored. From the Auto Select mode the Manufacturer Code can be read using a Bus Read operation with A0 = VIL and A1 = VIL. The other address bits may be set to either VIL or VIH. The Device Code can be read using a Bus Read operation with A0 = VIH and A1 = VIL. The other address bits may be set to either VIL or VIH. Word Program Command. The Word Program command can be used to program a Word to the memory array. VPP must be set to VHH during Word Program. If VPP is set to either VIL or VIH the command will be ignored, the data will remain unchanged and the device will re-
vert to Read/Reset mode. The command requires four Bus Write operations, the final write operation latches the address and data in the internal state machine and starts the P/E.C. During the program operation the memory will ignore all commands. It is not possible to issue any command to abort or pause the operation. Typical program times are given in Table 6. Bus Read operations during the program operation will output the Status Register on the Data Inputs/Outputs. See the section on the Status Register for more details. After the program operation has completed the memory will return to the Read mode, unless an error has occurred. When an error occurs the memory will continue to output the Status Register. A Read/Reset command must be issued to reset the error condition and return to Read mode. Note that the Program command cannot change a bit set at '0' back to '1'. Multiple Word Program Command The Multiple Word Program command can be used to program large streams of data. It greatly reduces the total programming time when a large number of Words are written in the memory at once. VPP must be set to VHH during Multiple Word Program. If VPP is set either VIL or VIH the command will be ignored, the data will remain unchanged and the device will revert to Read mode. It has four phases: the Setup Phase to initiate the command, the Program Phase to program the data to the memory, the Verify Phase to check that the data has been correctly programmed and reprogram if necessary and the Exit Phase. Setup Phase. The Multiple Word Program command requires three Bus Write operations to initiate the command (refer to Table 4, Multiple Word Program Command and Figure 8, Multiple Word Program Flowchart). The Status Register must be read in order to check that the P/E.C. has started (see Table 8 and Figure 8). Program Phase. The Program Phase requires n+1 Bus Write operations, where n is the number of Words, to execute the programming phase (refer to Table 5, Multiple Word Program and Figure 7, Multiple Word Program Flowchart). Before any Bus Write operation of the Program Phase, the Status Register must be read in order to check that the P/E.C. is ready to accept the operation (see Table 8 and Figure 8). The Program Phase is executed in three different sub-phases: 1. The first Bus Write operation of the Program Phase (the 4th of the command) latches the
9/24
M59PW1282
Start Address and the first Word to be programmed. 2. Each subsequent Bus Write operation latches the next Word to be programmed and automatically increments the internal Address Bus. It is not necessary to provide the address of the location to be programmed but only a Continue Address, CA (A17 to A21 equal to the Start Address), that indicates to the PC that the Program Phase has to continue. A0 to A16 are `don't care'. 3. Finally, after all Words have been programmed, a Bus Write operation (the (n+1)th) with a Final Address, FA (A17 or a higher address pin different from the Start Address), ends the Program Phase. The memory is now set to enter the Verify Phase. Verify Phase. The Verify Phase is similar to the Program Phase in that all Words must be resent to the memory for them to be checked against the programmed data. Before any Bus Write Operation of the Verify Phase, the Status Register must be read in order to check that the P/E.C. is ready for the next operation or if the reprogram of the location has failed (see Table 8 and Figure 8). Three successive steps are required to execute the Verify Phase of the command: 1. The first Bus Write operation of the Verify Phase latches the Start Address and the Word to be verified. 2. Each subsequent Bus Write operation latches the next Word to be verified and automatically increments the internal Address Bus. As in the Program Phase, it is not necessary to provide the address of the location to be programmed but only a Continue Address, CA (A17 to A21 equal to the Start Address). 3. Finally, after all Words have been verified, a Bus Write cycle with a Final Address, FA (A17 or a higher address pin different from the Start Address) ends the Verify Phase. Exit Phase. After the Verify Phase ends, the Status Register must be read to check if the command has successfully completed or not (see Table 8 and Figure 8). If the Verify Phase accomplishes successfully, the memory returns to the Read mode and DQ6 stops toggling. On the contrary, if the P/E.C. fails to reprogram a given location, the Verify Phase terminates, DQ6 continues toggling and error bit DQ5 is set in the Status Register. If the error is due to a VPP failure DQ4 is also set. When the operation fails a Read/Reset command must be issued to return the device to Read mode.

During the Multiple Word Program operation the memory will ignore all commands. It is not possible to issue any command to abort or pause the operation. Typical program times are given in Table 6. Bus Read operations during the program operation will output the Status Register on the Data Inputs/Outputs. See the section on the Status Register for more details. Note that the Multiple Word Program command cannot change a bit set at '0' back to '1'. Block Erase Command. The Block Erase command can be used to erase a block. It sets all of the bits in the block to '1'. All previous data in the block is lost. VPP must be set to VHH during Block Erase. If VPP is set to either VIL or VIH the command will be ignored, the data will remain unchanged and the device will revert to Read/Reset mode. Six Bus Write operations are required to select the block . The Block Erase operation starts the P/E.C. after the last Bus Write operation. The Status Register can be read after the sixth Bus Write operation. See the Status Register for details on how to identify if the P/E.C. has started the Block Erase operation. During the Block Erase operation the memory will ignore all commands. Typical block erase times are given in Table 6. All Bus Read operations during the Block Erase operation will output the Status Register on the Data Inputs/Outputs. See the section on the Status Register for more details. After the Block Erase operation has completed the memory will return to the Read Mode, unless an error has occurred. When an error occurs the memory will continue to output the Status Register. A Read/Reset command must be issued to reset the error condition and return to Read mode. Chip Erase Command. The Chip Erase command can be used to erase the entire memory. It sets all of the bits in the memory to '1'. All previous data in the memory is lost. VPP must be set to VHH during Chip Erase. If VPP is set to either VIL or VIH the command will be ignored, the data will remain unchanged and the device will revert to Read/Reset mode. Six Bus Write operations are required to issue the Chip Erase Command and start the P/E.C. During the erase operation the memory will ignore all commands. It is not possible to issue any command to abort the operation. Typical chip erase times are given in Table 6. All Bus Read operations during the Chip Erase operation will output the Status Register on the Data Inputs/Outputs. See the section on the Status Register for more details.

STATUS REGISTER Bus Read operations from any address always read the Status Register during Program and Erase operations. The bits in the Status Register are summarized in Table 8, Status Register Bits. Data Polling Bit (DQ7). The Data Polling Bit can be used to identify whether the P/E.C. has successfully completed its operation. The Data Polling Bit is output on DQ7 when the Status Register is read. During a Word Program operation the Data Polling Bit outputs the complement of the bit being programmed to DQ7. After successful completion of the Word Program operation the memory returns to Read mode and Bus Read operations from the address just programmed output DQ7, not its complement. During Erase operations the Data Polling Bit outputs '0', the complement of the erased state of DQ7. After successful completion of the Erase operation the memory returns to Read Mode. Figure 8, Data Polling Flowchart, gives an example of how to use the Data Polling Bit. A Valid Address is the address being programmed or an address within the block being erased. Toggle Bit (DQ6). The Toggle Bit can be used to identify whether the P/E.C. has successfully completed its operation. The Toggle Bit is output on DQ6 when the Status Register is read. During Program and Erase operations the Toggle Bit changes from '0' to '1' to '0', etc., with successive Bus Read operations at any address. After successful completion of the operation the memory returns to Read mode. Figure 9, Data Toggle Flowchart, gives an example of how to use the Data Toggle Bit. Error Bit (DQ5). The Error Bit can be used to identify errors detected by the P/E.C. The Error Bit is set to '1' when a Program, Block Erase or Chip Erase operation fails to write the correct data to the memory. If the Error Bit is set a Read/Reset command must be issued before other commands are issued. The Error bit is output on DQ5 when the Status Register is read.
Note that the Program command cannot change a bit set to '0' back to '1' and attempting to do so will set DQ5 to `1'. A Bus Read operation to that address will show the bit is still `0'. One of the Erase commands must be used to set all the bits in a block or in the whole memory from '0' to '1'. VPP Status Bit (DQ4). The VPP Status Bit can be used to identify if any Program or Erase operation has failed due to a VPP error. If VPP falls below VHH during any Program or Erase operation, the operation aborts and DQ4 is set to `1'. If VPP remains at VHH throughout the Program or Erase operation, the operation completes and DQ4 is set to `0'. Erase Timer Bit (DQ3). The Erase Timer Bit can be used to identify the start of P/E.C. operation during a Block Erase command. Once the P/E.C. starts erasing the Erase Timer Bit is set to '1'. The Erase Timer Bit is output on DQ3 when the Status Register is read. Alternative Toggle Bit (DQ2). The Alternative Toggle Bit can be used to monitor the P/E.C. during Block Erase operations. The Alternative Toggle Bit is output on DQ2 when the Status Register is read. During Block Erase operations the Toggle Bit changes from '0' to '1' to '0', etc., with successive Bus Read operations from addresses within the block being erased. Once the operation completes the memory returns to Read mode. After an Erase operation that causes the Error Bit to be set, the Alternative Toggle Bit can be used to identify where the error occurred. The Alternative Toggle Bit changes from '0' to '1' to '0', etc. with successive Bus Read Operations from addresses within a block that has not erased correctly. The Alternative Toggle Bit does not change if the addressed block has erased correctly. Multiple Word Program Bit (DQ0). The Multiple Word Program Bit can be used to indicate whether the P/E.C. is active or inactive during Multiple Word Program. When the P/E.C. has written one Word and is ready to accept the next Word, the bit is set to `0'. Status Register Bit DQ1 is reserved.
