Description
The M58PR256J and M58PR512J are 256 Mbit (16 Mbit x16) and 512 Mbit (32 Mbit x16) non-volatile Flash memories, respectively. They are referred to as M58PRxxxJ in the rest of the document unless otherwise specified. The M58PRxxxJ may be erased electrically at Block level and programmed in-system on a Word-by-Word basis using a 1.7 V to 2.0 V VDD supply for the circuitry and a 1.7 V to 2.0 V VDDQ supply for the Input/Output pins. An optional 9 V VPP power supply is provided to speed up factory programming. The M58PRxxxJ has a uniform Block architecture and is based on a Multi-Level cell technology. The M58PR256J has an array of 128 Blocks, and is divided into 32 Mbit banks. There are 8 banks each containing 16 Blocks of 128 KWords. The M58PR512J has an array of 256 Blocks, and is divided into 64 Mbit banks. There are 8 Banks each containing 32 Blocks of 128 KWords. Each Block contains 256 Program Regions of 1 KByte each, that are divided into 32 Segments of 16 Words. Each Segment is split into two halves (A and B), according by the value on Address Input A3. The memory map is illustrated in Figure 2, and the Main Array architecture in Figure 3. The Multiple Bank Architecture allows Dual Operations, while programming or erasing in one bank, read operations are possible in other banks. Only one bank at a time is allowed to be in program or erase mode. It is possible to perform burst reads that cross bank boundaries. The bank architecture is summarized in Table 2, and the memory maps are shown in Figure 2. Each Block can be erased separately. Erase can be suspended, in order to perform a program or read operation in any other Block, and then resumed. Program can be suspended to read data at any memory location except for the one being programmed, and then resumed. Each Block can be programmed and erased over 100,000 cycles using the supply voltage VDD. There is a Buffer Enhanced Factory programming command available to speed up programming. Program and erase commands are written to the Command Interface of the memory. An internal Program/Erase Controller takes care of the timings necessary for program and erase operations. The end of a program or erase operation can be detected and any error conditions identified in the Status Register. The command set required to control the memory is consistent with JEDEC standards. The device supports Synchronous Burst Read and Asynchronous Read from all Blocks of the memory array; at power-up the device is configured for Asynchronous Read. In Synchronous Burst Read mode, data is output on each clock cycle at frequencies of up to 108 MHz. The Synchronous Burst Read operation can be suspended and resumed. The device features an Automatic Standby mode and Deep Power-Down mode. When the bus is inactive during Asynchronous Read operations, the device automatically switches to the Automatic Standby mode. In this condition the power consumption is reduced to the standby value and the outputs are still driven.

Description
M58PR256J, M58PR512J The Deep Power Down (DPD) mode starts when the device is properly configured (ECR bit 15 is set) and the DPD signal is asserted. In DPD mode the device has the lowest power consumption. The M58PRxxxJ features an instant, individual block locking scheme that allows any Block to be locked or unlocked with no latency, enabling instant code and data protection. All Blocks have three levels of protection. They can be locked and locked-down individually preventing any accidental programming or erasure. There is an additional hardware protection against program and erase. When VPP VPPLK all Blocks are protected against program or erase. All Blocks are locked at power-up. In addition to the main memory array, the M58PRxxxJ features an Extended Flash Array (EFA) divided into 4 Blocks of 64 Kbits each. The EFA Blocks are accessed through a separate set of commands. The operations available in the EFA Blocks are Asynchronous Read (in Non-Page mode), Single Word Program, erase and block locking. See Section 4: Command interface for details of the EFA commands set. See Table 4 for an Extended Flash Array memory map. Table 18 and Table 19 describe the simultaneous operations allowed in the EFA Blocks and the Main Memory array. The device includes 17 Protection Registers and 2 Protection Register locks, one for the first Protection Register and the other for the 16 One-Time-Programmable (OTP) Protection Registers of 128 bits each. The first Protection Register is divided into two areas: a 64 bit area containing a unique device number written by ST, and a 64 bit area One-TimeProgrammable (OTP) by the user. The user programmable area can be permanently protected. Figure 4, shows the Protection Register memory map. The memory is supplied with all the bits erased (set to '1'). Note that the M58PRxxxJ memories are only available as part of a multi-chip package device.

Signal descriptions
See Figure 1: Logic diagram and Table 1: Signal names, for a brief overview of the signals connected to this device.
2.1
Address Inputs (A0-Amax)
Amax is the highest order Address Input. Amax is A23 in the M58PR256J, and A24 in the M58PR512J. 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.
2.2
Data Input/Output (DQ0-DQ15)
The Data I/O output the data stored at the selected address during a Bus Read operation or input a command or the data to be programmed during a Bus Write operation.
2.3
Chip Enable (E)
The Chip Enable input activates the memory control logic, input buffers, decoders and sense amplifiers. When Chip Enable is at VILand Reset is at VIH the device is in active mode. When Chip Enable is at VIH the memory is deselected, the outputs are high impedance and the power consumption is reduced to the stand-by level.
2.4
Output Enable (G)
The Output Enable input controls data outputs during the Bus Read operation of the memory.
2.5
Write Enable (W)
The Write Enable input controls the Bus Write operation of the memory's Command Interface. The data and address inputs are latched on the rising edge of Chip Enable or Write Enable whichever occurs first.
2.6
Write Protect (WP)
Write Protect is an input that gives an additional hardware protection for each Block. When Write Protect is at VIL, the Lock-Down is enabled and the protection status of the LockedDown Blocks cannot be changed. When Write Protect is at VIH, the Lock-Down is disabled and the Locked-Down Blocks can be locked or unlocked. (refer to Table 21: Lock status).
14/114
M58PR256J, M58PR512J
Signal descriptions
2.7
Reset (RP)
The Reset input provides a hardware reset of the memory. When Reset is at VIL, the memory is in reset mode: the outputs are high impedance and the current consumption is reduced to the Reset Supply Current IDD2. Refer to Table 26: DC characteristics - currents, for the value of IDD2. After Reset all Blocks are in the Locked state and the Configuration Register is reset. When Reset is at VIH, the device is in normal operation. Exiting reset mode the device enters asynchronous read mode, but a negative transition of Chip Enable or Latch Enable is required to ensure valid data outputs. The Reset pin can be interfaced with 3V logic without any additional circuitry. It can be tied to VRPH (refer to Table 27: DC characteristics - voltages).
2.8
Deep Power-Down (DPD)
The Deep Power-Down input is used to put the device in Deep Power-Down mode. When the device is in Standby mode and the Enhanced Configuration Register bit ECR15 is set, asserting the Deep Power-Down input will cause the memory to enter the Deep PowerDown mode. When the device is in the Deep Power-Down mode, the memory cannot be modified and the data is protected. The polarity of the DPD pin is determined by ECR14. The Deep Power-Down input is active Low by default.
2.9
Latch Enable (L)
Latch Enable latches the address bits on its rising edge. The address latch is transparent when Latch Enable is at VIL and it is inhibited when Latch Enable is at VIH. Latch Enable can be kept Low (also at board level) when the Latch Enable function is not required or supported.
2.10
Clock (K)
The clock input synchronizes the memory to the microcontroller during synchronous read operations; the address is latched on a Clock edge when Latch Enable is at VIL. Clock is ignored during asynchronous read and in write operations.
2.11
Wait (WAIT)
Wait is an output signal used during synchronous read to indicate whether the data on the output bus are valid. This output is high impedance when Chip Enable is at VIH, Output Enable is at VIH, or Reset is at VIL. It can be configured to be active during the wait cycle or one data cycle in advance.

Signal descriptions
M58PR256J, M58PR512J
2.12
VDD supply voltage
VDD provides the power supply to the internal core of the memory device. It is the main power supply for all operations (Read, Program and Erase).
2.13
VDDQ supply voltage
VDDQ provides the power supply to the I/O pins and enables all Outputs to be powered independently of VDD. VDDQ can be tied to VDD or can use a separate supply. VDDQ is sampled at the beginning of program/erase operations. If VDDQ is lower than VLKOQ, the device is reset.
2.14
VPP Program supply voltage
VPP is both a control input and a power supply pin. The two functions are selected by the voltage range applied to the pin. If VPP is kept in a low voltage range (0V to VDDQ) VPP is seen as a control input. In this case a voltage lower than VPPLK gives an absolute protection against program or erase, while VPP > VPP1 enables these functions (see Tables 26 and 27, DC Characteristics for the relevant values). VPP is only sampled at the beginning of a program or erase; a change in its value after the operation has started does not have any effect and program or erase operations continue. If VPP is in the range of VPPH it acts as a power supply pin. In this condition VPP must be stable until the Program/Erase algorithm is completed.
2.15
VSS ground
VSS ground is the reference for the core supply. It must be connected to the system ground.
2.16
VSSQ ground
VSSQ ground is the reference for the input/output circuitry driven by VDDQ. VSSQ must be connected to VSS
Note:
Each device in a system should have VDD, VDDQ and VPP decoupled with a 0.1 F ceramic capacitor close to the pin (high frequency, inherently low inductance capacitors should be as close as possible to the package). See Figure 9: AC measurement load circuit. The PCB track widths should be sufficient to carry the required VPP program and erase currents.

Bus operations
3
Bus operations
There are seven standard bus operations that control the device. These are Bus Read, Bus Write, Address Latch, Output Disable, Standby, Reset and Deep Power-Down. See Table 5: 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 Write operations.
3.1
Bus Read
Bus Read operations are used to output the contents of the Memory Array, the Electronic Signature, the Status Register and the Common Flash Interface. Both Chip Enable and Output Enable must be at VIL in order to perform a read operation. The Chip Enable input should be used to enable the device. Output Enable should be used to gate data onto the output. The data read depends on the previous command written to the memory (see Command Interface section). See Figures 10, 11, 12 and 13 Read AC Waveforms, and Tables 28 and 29 Read AC Characteristics, for details of when the output becomes valid.
3.2
Bus Write
Bus Write operations write Commands to the memory or latch Input Data to be programmed. A bus write operation is initiated when Chip Enable and Write Enable are at VIL with Output Enable at VIH. Commands, Input Data and Addresses are latched on the rising edge of Write Enable or Chip Enable, whichever occurs first. The addresses can also be latched prior to the write operation by toggling Latch Enable. In this case the Latch Enable should be tied to VIH during the bus write operation. See Figures 15 and 16, Write AC Waveforms, and Tables 30 and 31, Write AC Characteristics, for details of the timing requirements.
3.3
Address Latch
Address latch operations input valid addresses. Both Chip enable and Latch Enable must be at VIL during address latch operations. The addresses are latched on the rising edge of Latch Enable.
3.4
Output Disable
The outputs are high impedance when the Output Enable is at VIH.
17/114
Bus operations
M58PR256J, M58PR512J
3.5
Standby
Standby disables most of the internal circuitry allowing a substantial reduction of the current consumption. The memory is in standby when Chip Enable and Reset are at VIH. The power consumption is reduced to the standby level IDD3 and the outputs are set to high impedance, independently from the Output Enable or Write Enable inputs. If Chip Enable switches to VIH during a program or erase operation, the device enters Standby mode when finished.
3.6
Reset
During Reset mode the memory is deselected and the outputs are high impedance. The memory is in Reset mode when Reset is at VIL. The power consumption is reduced to the Reset level, independently from the Chip Enable, Output Enable or Write Enable inputs. If Reset is pulled to VSS during a Program or Erase, this operation is aborted and the memory content is no longer valid.
3.7
Deep Power-Down (DPD)
The memory enters the Deep Power-Down mode from the Standby mode (RP and E are deasserted, VIH) by setting ECR15 High (set to `1') and asserting the DPD pin, whatever the order of the last two events. The DPD pin polarity is determined by the value of ECR14:

when ECR14 is cleared (`0') the DPD pin is active Low. The DPD pin is active Low by default. when ECR14 is set (`1'), the DPD pin is active High. the values of Configuration Register, Enhanced Configuration Register, Block Lock bits and Bank states are preserved. the Status Register is reset to 80h.
While in DPD mode:

If the Status Register contains errors before entering the DPD mode, the error bits will be lost after exiting DPD mode. The device should not be put in Deep Power-Down mode while a program, erase or suspend operation is in progress. If the device is put in Deep Power-Down mode during a program, erase or suspend operation, the operation will abort, and the memory contents will no longer be valid. The Deep Power-Down mode is exited tDPHEL after de-asserting the DPD pin. On exiting the Deep Power-Down mode, the memory reverts to the Standby mode. If the RP pin is asserted while in DPD mode, the device exits DPD mode after tPHEL and ECR15 is reset to 0.

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. An internal Program/Erase Controller handles all timings and verifies the correct execution of the program and erase commands. The Program/Erase Controller provides a Status Register whose output may be read at any time to monitor the progress or the result of the operation. The Command Interface is reset to read mode when power is first applied, when exiting from Reset or whenever VDD is lower than VLKO. Command sequences must be followed exactly. Any invalid combination of commands will be ignored. Refer to Table 6: Command codes, Table 7: Standard commands, Table 8: Factory Program command, for a summary of the Command Interface. Table 6.

Read Array command
The Read Array command returns the addressed bank to Read Array mode. One Bus Write cycle is required to issue the Read Array command. Once a bank is in Read Array mode, subsequent read operations will output the data from the memory array. A Read Array command can be issued to any banks while programming or erasing in another bank. If the Read Array command is issued to a bank currently executing a program or erase operation, the bank will return to Read Array mode but the program or erase operation will continue, however the data output from the bank is not guaranteed until the program or erase operation has finished. The read modes of other banks are not affected.
4.2
Read Status Register command
The device contains a Status Register that is used to monitor program or erase operations. The Read Status Register command is used to read the contents of the Status Register for the addressed bank. One Bus Write cycle is required to issue the Read Status Register command. Once a bank is in Read Status Register mode, subsequent read operations will output the contents of the Status Register. The Status Register data is latched on the falling edge of the Chip Enable or Output Enable signals. Either Chip Enable or Output Enable must be toggled to update the Status Register data The Read Status Register command can be issued at any time, even during program or erase operations. The Read Status Register command will only change the read mode of the addressed bank. The read modes of other banks are not affected. Only Asynchronous Read and Single Synchronous Read operations should be used to read the Status Register. A Read Array command is required to return the bank to Read Array mode. See Table 13 for the description of the Status Register Bits.

4.3
Read Electronic Signature command
The Read Electronic Signature command is used to read the Manufacturer and Device Codes, the Lock Status of the addressed bank, the Protection Register, the Configuration Register and the Enhanced Configuration Register. One Bus Write cycle is required to issue the Read Electronic Signature command. Once a bank is in Read Electronic Signature mode, subsequent read operations in the same bank will output the Manufacturer Code, the Device Code, the Lock Status of the addressed bank, the Protection Register, the Configuration Register or the Enhanced Configuration Register (see Table 9). The Read Electronic Signature command can be issued at any time, even during program or erase operations, except during Protection Register Program operations. Dual operations between the Extended Flash Array (EFA) and the Electronic Signature locations are not allowed (see Table 20: Dual operation limitations for details). If a Read Electronic Signature command is issued to a bank that is executing a program or erase operation the bank will go into Read Electronic Signature mode. Subsequent Bus Read cycles will output the Electronic Signature data and the Program/Erase controller will continue to program or erase in the background. The Read Electronic Signature command will only change the read mode of the addressed bank. The read modes of other banks are not affected. Only Asynchronous Read and Single Synchronous Read operations should be used to read the Electronic Signature. A Read Array command is required to return the bank to Read Array mode.
4.4
Read CFI Query command
The Read CFI Query command is used to read data from the Common Flash Interface (CFI). One Bus Write cycle is required to issue the Read CFI Query command. Once a bank is in Read CFI Query mode, subsequent Bus Read operations in the same bank will output the contents of the Common Flash Interface. The Read CFI Query command can be issued at any time, even during program or erase operations. If a Read CFI Query command is issued to a bank that is executing a program or erase operation the bank will go into Read CFI Query mode. Subsequent Bus Read cycles will output the CFI data and the Program/Erase controller will continue to program or erase in the background. The Read CFI Query command will only change the read mode of the addressed bank. The read modes of other banks are not affected. Only Asynchronous Read and Single Synchronous Read operations should be used to read from the CFI. A Read Array command is required to return the bank to Read Array mode. Dual operations between the Extended Flash Array (EFA) and the CFI memory space are not allowed (see Table 20: Dual operation limitations for details).

Clear Status Register command
The Clear Status Register command can be used to reset (set to `0') all error bits (SR1, SR3, SR4, SR5, SR8 and SR9) in the Status Register. One Bus Write cycle is required to issue the Clear Status Register command. The Clear Status Register command does not affect the read mode of the bank. The error bits in the Status Register do not automatically return to `0' when a new command is issued. The error bits in the Status Register should be cleared before attempting a new program or erase command.
4.6
Block Erase command
The Block Erase command is used to erase a Block. It sets all the bits within the selected Block to '1'. All previous data in the Block is lost. If the Block is protected then the erase operation will abort, the data in the Block will not be changed and the Status Register will output the error. Two Bus Write cycles are required to issue the command.

The first bus cycle sets up the Block Erase command. The second latches the Block address and starts the Program/Erase Controller.
If the second bus cycle is not the Block Erase Confirm code, Status Register bits SR4 and SR5 are set and the command is aborted. Once the command is issued the bank enters Read Status Register mode and any read operation within the addressed bank will output the contents of the Status Register. A Read Array command is required to return the bank to Read Array mode. During Block Erase operations the bank containing the Block being erased will only accept the Read Array, Read Status Register, Read Electronic Signature, Read CFI Query and the Program/Erase Suspend command, all other commands will be ignored. The Block Erase operation aborts if Reset, RP, goes to VIL. As data integrity cannot be guaranteed when the Block Erase operation is aborted, the Block must be erased again. Refer to Dual Operations section for detailed information about simultaneous operations allowed in banks not being erased. Typical Erase times are given in Table 22: Program/Erase times and endurance cycles. See Appendix C, Figure 23: Block Erase and EFA Block Erase flowchart and pseudo code, for a suggested flowchart for using the Block Erase command.

4.7
Program command
The Program command is used to program a single Word to the memory array. It is supported only by Program Regions configured in the Control Program mode. If a Program command is issued to a Program Region configured in the Object Program mode, the Program operation is aborted and the SR4 and SR8 Status Register bits are set (see Section 5: Program operations). Two Bus Write cycles are required to issue the Program Command.

The first bus cycle sets up the Program command. The second latches the address and data to be programmed and starts the Program/Erase Controller.
The Program command has to be written to the 'A' Segment halves (address bit A3 = 0) in the 1 KByte Program Region, whereas the data to be programmed is written to the specific address of the bank to be programmed. Once the programming has started, read operations in the bank being programmed output the Status Register contents. Programming can be performed in one bank at a time, meanwhile the other banks must be in Read or Erase Suspend mode. The Status Register P/E.C. bit, SR7, indicates the progress of the Program operation. It should be read to check whether the operation has completed or not. After completion of the Program operation (SR7 = 1), one of the error bits (SR4, SR3 and SR1) going High means that an error was detected: either a failure occurred during programming, VPP is outside the allowed voltage range or an attempt to program a locked Block was made. See Section 6: Status Register for detailed information. During a Program operation, the bank containing the Word being programmed will only accept the Read Array, Read Status Register, Read Electronic Signature, Read CFI Query and the Program/Erase Suspend command, all other commands will be ignored. A Read Array command is required to return the bank to Read Array mode. Refer to Dual Operations section for detailed information about simultaneous operations allowed in banks not being programmed. Typical Program times are given in Table 22: Program/Erase times and endurance cycles. The Program operation aborts if Reset, RP, goes to VIL. As data integrity cannot be guaranteed when the Program operation is aborted, the Word must be reprogrammed. See Appendix C, Figure 20: Program and EFA Block Program flowchart and pseudo code, for the flowchart for using the Program command.

Buffer Program command
The Buffer Program Command makes use of the device's 1 KByte Write Buffer to speed up programming. Up to 1 KByte can be loaded into the Write Buffer and programmed into the specified 1KB aligned location in the main array. The Buffer Program command dramatically reduces in-system programming time compared to the standard non-buffered Program command. The Buffer Program command is supported in both the Object Program mode and the Control Program mode. When using the Buffer Program command in a region configured in Object mode, the start programming address must be aligned to the 1KB buffer. When using the Buffer Program command in a region configured in the Control Program mode, the programmed address must be within the 'A' Segment halves of the Program Region (addresses with A3 = 0) and the 'B' Segment halves of the Program Region (addresses with A3 = 1) must be filled only with FFFFh data. Before issuing the Buffer Program Setup command, the status register bit SR7 at bank address should be read to ensure that the buffer is available (SR7=1). Four successive steps are required to issue the Buffer Program command: 1. 2. The first Bus Write cycle sets up the Buffer Program command. The setup code can be addressed to any location within the targeted Block. The second Bus Write cycle sets up the number of Words to be programmed. Value n is written to the same Block address, where n+1 is the number of Words to be programmed. The maximum buffer count is 1FF (512 Words). Use n+1 Bus Write cycles to load the address and data for each Word into the Write Buffer. Addresses must lie within the range from the start address to the start address + n, where the start address is the location of the first data to be programmed. The start address must be aligned to a 1 KB boundary. The final Bus Write cycle confirms the Buffer Program command and starts the program operation.
3.
4.
All the addresses used in the Buffer Program operation must lie within the same Block. The Buffer Program operation does not change the Read Status of the banks until the Buffer Program Confirm Command is issued. The Buffer Program Confirm Command change the Read Status of the Bank to Read Status Register so after Buffer Program Confirm Command, read operations in the bank will output the contents of the Status Register. Invalid address combinations or failing to follow the correct sequence of Bus Write cycles will set an error in the Status Register and abort the operation without affecting the data in the memory array. If the Block being programmed is protected an error will be set in the Status Register and the operation will abort without affecting the data in the memory array. During Buffer Program operations the bank being programmed will only accept the Read Array, Read Status Register, Read Electronic Signature, Read CFI Query and the Program/Erase Suspend command, all other commands will be ignored. Refer to Dual Operations section for detailed information about simultaneous operations allowed in banks not being programmed. See Appendix C, Figure 21: Buffer Program flowchart and pseudo code, for a suggested flowchart on using the Buffer Program command.

Buffer Enhanced Factory Program command
The Buffer Enhanced Factory Program command has been specially developed to speed up programming in manufacturing environments where the programming time is critical. It is used to program one or more Write Buffer(s) of 1KB to an aligned 1KB Program Region. Once the device enters Buffer Enhanced Factory Program mode, the Write Buffer can be reloaded any number of times as long as the address remains within the same main array Block. Only one Block can be programmed at a time. When programming a Program Region configured in Control Program mode with the Buffer Enhanced Factory Program command, 'B' half Segment addresses (A3 = 1) should not contain '0' values. When writing to a Program Region configured in Object Program mode the B half may contain some '0' values. If the number of Bytes to program is less than 1 KByte, the remaining addresses must be filled with FFFFh. The use of the Buffer Enhanced Factory Program command requires certain operating conditions:

VPP must be set to VPPH VDD must be within operating range Ambient temperature TA must be 30C 10C The targeted Block must be unlocked The start address must be aligned with the start of a 1KB buffer boundary The address must remain the Start Address throughout programming.
Dual operations are not supported during the Buffer Enhanced Factory Program operation and the command cannot be suspended. The Buffer Enhanced Factory command programs one Block at a time. All data to be programmed must be contained in a single Block. If the internal address counter is incremented beyond the highest Block address, addressing wraps around to the beginning of the Block. The Buffer Enhanced Factory Program Command consists of three phases: the Setup Phase, the Program and Verify Phase, and the Exit Phase, Please refer to Table 8: Factory Program command for detail information.
4.10
Setup phase
The Buffer Enhanced Factory Program command requires two Bus Write cycles to initiate the command.

The first Bus Write cycle sets up the Buffer Enhanced Factory Program command. The second Bus Write cycle confirms the command.
After the confirm command is issued, read operations output the contents of the Status Register. The read Status Register command must not be issued as it will be interpreted as data to program. The Status Register P/E.C. Bit SR7 should be read to check that the P/E.C. is ready to proceed to the next phase. If an error is detected, SR4 goes high (set to `1') and the Buffer Enhanced Factory Program operation is terminated. See Status Register section for details on the error.

4.11
Program and Verify phase
The Program and Verify Phase requires 512 cycles to program the 512 Words to the Write Buffer. The data is stored sequentially, starting at the first address of the Write Buffer, until the Write Buffer is full (512 Words). To program less than 512 Words, the remaining Words should be programmed with FFFFh. Three successive steps are required to issue and execute the Program and Verify Phase of the command. 1. Use one Bus Write operation to latch the Start Address and the first Word to be programmed. The Status Register Bank Write Status bit SR0 should be read to check that the P/E.C. is ready for the next Word. Each subsequent Word to be programmed is latched with a new Bus Write operation. The address must remain the Start Address as the P/E.C. increments the address location.If any address that is not in the same Block as the Start Address is given, the Program and Verify Phase terminates. Status Register bit SR0 should be read between each Bus Write cycle to check that the P/E.C. is ready for the next Word. Once the Write Buffer is full, the data is programmed sequentially to the memory array. After the program operation the device automatically verifies the data and reprograms if necessary.
2.
3.
The Program and Verify phase can be repeated, without re-issuing the command, to program additional 512 Word locations as long as the address remains in the same Block. 4. Finally, after all Words, or the entire Block have been programmed, write FFFFh to any address outside the Block containing the Start Address, to terminate the Program and Verify Phase.
Status Register bit SR0 must be checked to determine whether the program operation is finished. The Status Register may be checked for errors at any time but it must be checked after the entire Block has been programmed.
4.12
Exit phase
Status Register P/E.C. bit SR7 set to `1' indicates that the device has exited the Buffer Enhanced Factory Program operation. On exiting the Buffered Enhanced Factory Program algorithm by writing FFFFh to an address outside the Block containing the start address, the read mode of the programmed and addressed banks remains unchanged. A full Status Register check should be done to ensure that the Block has been successfully programmed. See the section on the Status Register for more details. For optimum performance the Buffer Enhanced Factory Program command should be limited to a maximum of 100 program/erase cycles per Block. If this limit is exceeded the internal algorithm will continue to work properly but some degradation in performance is possible. Typical program times are given in Table 22. See Appendix C, Figure 28: Buffer Enhanced Factory Program flowchart and pseudo code, for a suggested flowchart on using the Buffer Enhanced Factory Program command.

4.13
Program/Erase Suspend command
The Program/Erase Suspend command is used to pause a Program or Block Erase operation. The command can be addressed to any bank. The Program/Erase Resume command is required to restart the suspended operation. One bus write cycle is required to issue the Program/Erase Suspend command. Once the Program/Erase Controller has paused bits SR7, SR6 and/ or SR2 of the Status Register will be set to `1'. The following commands are accepted during Program/Erase Suspend: - - - - - - Program/Erase Resume Read Array (data from erase-suspended Block or program-suspended Word is not valid) Read Status Register Read Electronic Signature Read CFI Query Read EFA
Additionally, if the suspended operation was a Block Erase then the following commands are also accepted: - - - - - - - Clear Status Register Program (except in erase-suspended Block) Buffer Program (except in erase suspended Blocks) Block Lock Block Lock-Down Block Unlock Program EFA
During an erase suspend the Block being erased can be protected by issuing the Block Lock or Block Lock-Down commands. When the Program/Erase Resume command is issued the operation will complete. It is possible to accumulate multiple suspend operations. For example: suspend an erase operation, start a program operation, suspend the program operation, then read the array. If a Program command is issued during a Block Erase Suspend, the erase operation cannot be resumed until the program operation has completed. The Program/Erase Suspend command does not change the read mode of the banks. If the suspended bank was in Read EFA, Read Status Register, Read Electronic signature or Read CFI Query mode the bank remains in that mode and outputs the corresponding data. Refer to Dual Operations section for detailed information about simultaneous operations allowed during Program/Erase Suspend. During a Program/Erase Suspend, the device can be placed in standby mode by taking Chip Enable to VIH. Program/erase is aborted if Reset, RP, goes to VIL. See Appendix C, Figure 22: Program Suspend & Resume flowchart and pseudo code, for flowcharts for using the Program/Erase Suspend command.

Program/Erase Resume command
The Program/Erase Resume command is used to restart the program or erase operation suspended by the Program/Erase Suspend command. One Bus Write cycle is required to issue the command. The command can be issued to any address. The Program/Erase Resume command does not change the read mode of the banks. If the suspended bank was in Read Status Register, Read Electronic signature or Read CFI Query mode the bank remains in that mode and outputs the corresponding data. If a Program command is issued during a Block Erase Suspend, then the erase cannot be resumed until the program operation has completed. See Appendix C, Figure 22: Program Suspend & Resume flowchart and pseudo code and Figure 24: Erase Suspend & Resume flowchart and pseudo code, for flowcharts for using the Program/Erase Resume command.
4.15
Protection Register Program command
The Protection Register Program command is used to program the user One-TimeProgrammable (OTP) area of the Protection Register and the two Protection Register Locks. The device features 16 OTP areas of 128 bits and one OTP area of 64 bits, as shown in Figure 4: Protection Register memory map. The areas are programmed one Word at a time. When shipped all bits in the area are set to `1'. The user can only program the bits to `0'. Two Bus Write cycles are required to issue the Protection Register Program command.

The first bus cycle sets up the Protection Register Program command. The second latches the address and data to be programmed to the Protection Register and starts the Program/Erase Controller.
Read operations to the bank being programmed output the Status Register content after the program operation has started. Attempting to program a previously protected Protection Register will result in a Status Register error. The Protection Register Program cannot be suspended. Dual operations between the Extended Flash Array (EFA) and the Protection Register memory space are not allowed (see Table 20: Dual operation limitations for details). The two Protection Register Locks are used to protect the OTP areas from further modification. The protection of the OTP areas is not reversible. Refer to Figure 4: Protection Register memory map, for details on the Lock bits. See Appendix C, Figure 27: Protection Register Program flowchart and pseudo code, for a flowchart for using the Protection Register Program command.

Set Configuration Register command
The Set Configuration Register command is used to write a new value to the Configuration Register. Two Bus Write cycles are required to issue the Set Configuration Register command.

The first cycle sets up the Set Configuration Register command and the address corresponding to the Configuration Register content. The second cycle writes the Configuration Register data and the confirm command.
The Configuration Register data must be written as an address during the bus write cycles, that is A0 = CR0, A1 = CR1, ..., A15 = CR15. Addresses A16-Amax are ignored. Read operations output the array content after the Set Configuration Register command is issued. The Read Electronic Signature command is required to read the updated contents of the Configuration Register.
4.17
Block Lock command
The Block Lock command is used to lock a Block and prevent program or erase operations from changing the data in it. All Blocks are locked after power-up or reset. Two Bus Write cycles are required to issue the Block Lock command.

The first bus cycle sets up the Block Lock command. The second Bus Write cycle latches the Block address and locks the Block.
The lock status can be monitored for each Block using the Read Electronic Signature command. Table 21 shows the Lock Status after issuing a Block Lock command. Once set, the Block Lock bits remain set even after a hardware reset or power-down/powerup. They are cleared by a Block Unlock command. Refer to the section, Block Locking, for a detailed explanation. See Appendix C, Figure 25: Main Array and EFA locking operations flowchart and pseudo code, for a flowchart for using the Lock command.
4.18
Block Unlock command
The Block Unlock command is used to unlock a Block, allowing the Block to be programmed or erased. Two Bus Write cycles are required to issue the Block Unlock command.

The first bus cycle sets up the Block Unlock command. The second Bus Write cycle latches the Block address and unlocks the Block.
The lock status can be monitored for each Block using the Read Electronic Signature command. Table 21 shows the protection status after issuing a Block Unlock command. Refer to the section, Block Locking, for a detailed explanation and Appendix C, Figure 25: Main Array and EFA locking operations flowchart and pseudo code, for a flowchart for using the Block Unlock command.

Block Lock-Down command
The Block Lock-Down command is used to lock-down a locked or unlocked Block. A locked-down Block cannot be programmed or erased. The lock status of a locked-down Block cannot be changed when WP is low, VIL. When WP is high, VIH, the lock-down function is disabled and the locked Blocks can be individually unlocked by the Block Unlock command. Two Bus Write cycles are required to issue the Block Lock-Down command.

The first bus cycle sets up the Block Lock-Down command. The second Bus Write cycle latches the Block address and locks-down the Block.
The lock status can be monitored for each Block using the Read Electronic Signature command. Locked-Down Blocks revert to the locked (and not locked-down) state when the device is reset on power-down. Table 21 shows the Lock Status after issuing a Block Lock-Down command. Refer to Section 12: Block locking, for a detailed explanation and Appendix C, Figure 25: Main Array and EFA locking operations flowchart and pseudo code, for a flowchart for using the Lock-Down command.
4.20
Blank Check command
The Blank Check command is used to check whether a Main Array Block has been completely erased. Only one Block at a time can be checked. Two bus cycles are required to issue the Blank Check command: The first bus cycle writes the Blank Check command to any address in the Block to be checked. The second bus cycle writes the Blank Check Confirm command (D0h) to any address in the Block to be checked and starts the Blank Check operation. If the second bus cycle is not Blank Check Confirm, Status Register bits SR4 and SR5 are set to `1' and the command aborts. Once the command is issued the addressed bank automatically enters the Status Register mode and further reads within the bank output the Status Register contents. The only operation permitted during Blank Check is Read Status Register. Dual Operations are not supported while a Blank Check operation is in progress. Blank Check operations cannot be suspended and are not allowed while the device is in Program/Erase Suspend. The SR7 Status Register bit indicates the status of the Blank Check operation in progress: SR7 = `0' means that the Blank Check operation is still ongoing. SR7 = `1' means that the operation is complete. The SR5 Status Register bit goes High (SR5 = `1') to indicate that the Blank Check operation has failed. At the end of the operation the bank remains in the Read Status Register mode until another command is written to the Command Interface. See Appendix C, Figure 26: Blank Check flowchart and pseudo code, for a suggested flowchart for using the Blank Check command. Typical Blank Check times are given in Figure 22: Program/Erase times and endurance cycles.

Set Enhanced Configuration Register command
The Set Enhanced Configuration Register command is used to write a new value to the Enhanced Configuration Register. Two Bus Write cycles are required to issue the Set Enhanced Configuration Register command.

The first cycle sets up the Set Enhanced Configuration Register command and the address corresponding to the Enhanced Configuration Register contents. The second cycle writes the Enhanced Configuration Register data and the Confirm command.
The Enhanced Configuration Register data must be written as an address during the bus write cycle, that is A0 = ECR0, A1 = ECR1, ..., A15 = ECR15. If the Set Enhanced Configuration Register setup write cycle is not followed by the Set Enhanced Configuration Register Confirm command (04h), Status Register bits SR4 and SR5 are set. After executing successfully this command, the bank addressed returns to Read Array state.
4.22
Read EFA Block command
The Read EFA Block command places the addressed bank in the Read EFA mode, where all addresses in the addressed bank are remapped to EFA Block addresses. When the device is in the Read EFA mode, the Main Array Blocks in the addressed bank can no longer be accessed until a Read Array Command is issued to the bank. One Bus Write cycle is required to issue the Read EFA Block command. Once a bank is in Read EFA mode, subsequent read operations from any address within the EFA Block will output the EFA data from the EFA Block. See Table 4: EFA memory map for details. EFA Blocks can be read through Asynchronous or Single Synchronous read operations only. The Asynchronous Page Read mode cannot be used to read the EFA Blocks. If a Read EFA command is issued in a bank that is programming or erasing, the read mode of the bank will change to Read EFA mode.

Program EFA Block command
The Program EFA Block command is used to program a single Word to an EFA Block. Two Bus Write cycles are required to issue the Program EFA Block command. The first bus cycle sets up the Program EFA Block command. The second cycle latches the address and data to be programmed and starts the Program/Erase Controller. Once the programming has started, read operations in the bank being programmed output the Status Register contents. Issuing the Program EFA Block command to an address outside the EFA Block address range generates a Program Error in the Status Register (SR4=1) A Read EFA Block command is required to return the bank to Read EFA mode. Refer to Section 11: Dual operations and multiple bank architecture for detailed information about simultaneous operations allowed in the banks not being programmed. Typical EFA Program times are given in Table 22: Program/Erase times and endurance cycles. The Program operation aborts if Reset, RP, is at VIL. As data integrity cannot be guaranteed when a Program EFA Block operation is aborted, the Word must be reprogrammed. See Appendix C, Figure 20: Program and EFA Block Program flowchart and pseudo code, for the flowchart for using the Program EFA Block command.
4.24
Erase EFA Block command
The Erase EFA Block command is used to erase an EFA Block. It sets all the bits within the selected Block to '1'. All previous data in the Block is lost. If the EFA Block is protected then the erase operation will abort, the data in the EFA Block will not be changed and the Status Register will output the error. Two Bus Write cycles are required to issue the command.

The first bus cycle sets up the Erase EFA Block command. The second latches the EFA Block address and starts the Program/Erase Controller.
The first cycle brings the EFA plane to the foreground and latches the address of the EFA Block to be erased. Reading from the bank when the EFA plane is in the foreground returns the Status Register. Once the erase operation has started, read operations in the bank being erased output the Status Register contents. If the Erase EFA Block Confirm command code is not issued in the second bus cycle, Status Register bits SR4 and SR5 are set, the command is aborted and the addressed bank remains in the Read Status Register mode. Issuing the Erase EFA Block command outside the EFA Block address range generates an error in the Status Register (SR5=1). The Erase EFA Block operation will abort if Reset, RP, is at VIL. As data integrity cannot be guaranteed when the Erase EFA Block operation is aborted, the Block must be erased again. Refer to Section 11: Dual operations and multiple bank architecture section for detailed information about simultaneous operations allowed with array and non-array Blocks. Typical Erase times are given in Table 22: Program/Erase times and endurance cycles.

The Resume EFA Block command is required to restart the suspended operation. One bus write cycle is required to issue the Suspend EFA Block command. Once the Program/Erase Controller has paused bits SR7, SR6 and/ or SR2 of the Status Register will be set to '1'. The following commands are accepted during Suspend EFA Block: - - - - - - Resume EFA Block Read Array Read EFA Block (data from Erase-Suspended Blocks or Program-Suspended Words is not valid) Read Status Register Read Electronic Signature Read CFI Query.
Additionally, if the suspended operation was an Erase EFA Block operation then the following commands are also accepted: - - - - - - - - - Clear Status Register Program EFA Block (except in the Erase-Suspended Block) Program and Buffer Program in the main array Block Lock Block Lock-Down Block Unlock EFA Block Lock EFA Block Lock-Down EFA Block Unlock
During Suspend EFA Block the EFA Block being erased can be protected by issuing the EFA Block Lock or EFA Block Lock-Down commands. When the Resume EFA Block command is issued the operation is resumed and completes. The Suspend EFA Block operation can be repeated. For example, it is possible to suspend an Erase EFA Block operation, to start a Program EFA Block operation, to suspend the program operation, then read EFA locations... If a Program EFA Block command is issued during a Suspend EFA Block operation, the Erase EFA Block operation cannot be resumed until the program operation has completed. The state of the bank where the command was issued will not change. Refer to Section 11: Dual operations and multiple bank architecture for detailed information about simultaneous operations allowed during a Suspend EFA Block operation. During a Suspend EFA Block operation, the device can be placed in standby mode by taking Chip Enable to VIH. Program/Erase is aborted if Reset, RP, is VIL. See Appendix C, Figure 22: Program Suspend & Resume flowchart and pseudo code and Figure 24: Erase Suspend & Resume flowchart and pseudo code, for flowcharts for using the Suspend EFA Block command.

Resume EFA Block command
The Resume EFA Block command is used to restart the Program or Erase EFA Block operation suspended by the Suspend EFA Block command. One Bus Write cycle is required to issue the command. The command can be issued to any address. The Resume EFA Block command does not change the read mode of the banks. If a Program EFA Block command is issued while an Erase EFA Block operation has been suspended, then the erase operation cannot be resumed until the program operation has completed. See Appendix C, Figure 22: Program Suspend & Resume flowchart and pseudo code and Figure 24: Erase Suspend & Resume flowchart and pseudo code, for flowcharts for using the Resume EFA Block command.
4.27
Lock EFA Block command
The Lock EFA Block command is used to lock an EFA Block and prevent program or erase operations from changing the data in it. All EFA Blocks are locked after power-up or reset. Two Bus Write cycles are required to issue the Lock EFA Block command.

The first bus cycle sets up the Lock EFA Block command. The second bus cycle latches the Block address and locks the Block.
The lock status can be monitored for each EFA Block using the Read Electronic Signature command. Once set, the Block Lock bits remain set even after a hardware reset or a powerdown/power-up sequence. They are cleared by an Unlock EFA Block command. Program or Erase operations to a locked EFA Block generates an error in the Status Register (SR1=1). Refer to Section 12: Block locking for a detailed explanation. See Appendix C, Figure 25: Main Array and EFA locking operations flowchart and pseudo code, for a flowchart for using the Lock EFA Block command.
4.28
Unlock EFA Block command
The Unlock EFA Block command is used to unlock an EFA Block, allowing the EFA Block to be programmed or erased. Two Bus Write cycles are required to issue the Unlock EFA Block command.

The first bus cycle sets up the Unlock EFA Block command. The second Bus Write cycle latches the Block address and unlocks the Block.
The lock status can be monitored for each EFA Block using the Read Electronic Signature command. Refer to Section 12: Block locking for a detailed explanation and to Appendix C, Figure 25: Main Array and EFA locking operations flowchart and pseudo code, for a flowchart for using the Unlock EFA Block command.

Lock-Down EFA Block command
The Lock-Down EFA Block command is used to lock down a locked or unlocked EFA Block. A locked-down EFA Block cannot be programmed or erased. The lock status of a lockeddown EFA Block cannot be changed when WP is low, VIL. When WP is High, VIH, the lockdown function is disabled and the locked EFA Blocks can be individually unlocked by issuing the Unlock EFA Block command. Two Bus Write cycles are required to issue the Lock-Down EFA Block command.

The first bus cycle sets up the Lock-Down EFA Block command. The second Bus Write cycle latches the Block address and locks down the Block.
The lock status can be monitored for each EFA Block using the Read Electronic Signature command. Locked-Down EFA Blocks revert to the locked (and not locked-down) state when the device is reset on power-down. Table 21 shows the Lock Status after issuing a Lock-Down EFA Block command. Refer to Section 12: Block locking for a detailed explanation and to Appendix C, Figure 25: Main Array and EFA locking operations flowchart and pseudo code, for a flowchart for using the Lock-Down EFA Block command.

Program operations
The M58PR256J and M58PR512J have innovative features specially developed to improve the storage flexibility and efficiency of NOR Flash memory arrays. Data and code can be stored more efficiently by using the right combination of program methods and program modes. There are two types of program methods, which use commands that consist of one or more sequential Bus Write operations interpreted by the Command Interface:

Single Word Program method, which uses the Program command. Buffered Program method, which uses either the Buffer Program command or the Buffer Enhanced Factory Program command. Control Program mode Object Program mode.
There are two program modes:

The Control Program mode supports the two program methods, whereas the Object Program mode only supports the Buffered Program method. This new logical organization of program operations is made possible by the device architecture, and in particular by the new concept of Program Regions.
5.1
Program Regions
Each Flash memory Block is divided into 256 Program Regions (see Figure 5: Program Regions configured in Control or Object Program mode). Erase operations have a Block granularity, whereas program operations have a Program Region granularity. The user can configure each Program Region to be programmed either in the Control Program mode or in the Object Program mode. A given Block can contain Program Regions configured in the Control Program mode and others configured in the Object Program mode. Special care should be taken when selecting the programming mode for the Program Regions because once the Program Regions are configured their program mode cannot be changed until the entire Block is erased. Each Program Region is split into 32 Segments of 32 Bytes and each Segment is subdivided into two halves, 'A' and 'B'. Address bit A3 determines whether a bit belongs to the 'A' half (A3 = 0) or to the 'B' half (A3 = 1).
5.2
Program modes
There are two program modes, which allow the Flash memory to store different types of data.
40/114
M58PR256J, M58PR512J
Program operations
5.3
Control Program mode
The Control Program mode is best suited to the storage of small, dynamic information. Typically such data is contained within one Program Region and it will be frequently updated and/or new data will be added to it. Program Regions are configured in the Control Program mode by programming data only to the 'A' halves (bit A3= 0) of the Segments they contain. The 'B' halves of the Segments must remain erased, that is they should not contain any zero's (see Figure 5: Program Regions configured in Control or Object Program mode). In a Program Region of 1KB configured in the Control Program mode, only 512B of data can be stored. When the Program Regions are configured in the Control Program mode, any program method can be used: the Single Word or the Buffered Program methods. Once a Program Region has been configured in the Control Program mode, if a zero is written to a 'B' half of one of its Segments, the program operation is terminated and an error is generated. The Status Register Bits SR4 and SR9 are set to `1'. (Refer to Status Register and to Table 12: Relationships between Program methods and Program modes, for details.) The program mode of a Program Region configured in the Control Program mode can only be changed by first erasing the Block that contains the Program Region.
5.4
Object Program mode
The Object Program mode is best suited to the storage of large, static information. In a Program Region of 1KB configured in the Object Program mode, 1KB of data can be stored. When a Program Region is configured in the Object Program mode, it cannot be reprogrammed or have new data added without first erasing the entire Block that contains the Program Region. Program Regions are configured in the Object Program mode simply by programming at least one bit in the 'B' half (A3 = 1) of one of the Segments they contain. If the programmed data is smaller than 1KB, the unused space remains in the erased state (all the bits set to FFFFh), but can no longer be used to program data. See Figure 5: Program Regions configured in Control or Object Program mode. When the Program Regions are configured in the Object Program mode, only the Buffered Program methods can be used. If an attempt is made to use the Single Word Program method, the program operation is aborted and Status Register error bits SR4 and SR8 are set to `1'. (Refer to Status Register and to Table 12: Relationships between Program methods and Program modes, for details.)

Program methods
The device supports two types of program methods:

Single Word Program method, which is used to program a single Word to a specific address of the memory array. Buffered Program methods, which can be split into two different methods: - a Buffer Program method that uses the device's Write Buffer to speed up programming. The data is written into the Write Buffer and then programmed to the specified Block address. a Buffer Enhanced Factory Program method, developed to speed up programming in manufacturing environments where the programming time is critical. The data is written in the Write Buffer and then programmed to the specified Block.
-
The following sections describe the relationship between program commands and Program methods in detail. See Table 12: Relationships between Program methods and Program modes and Table 11: Program methods available with each Program mode.
42/114
M58PR256J, M58PR512J
Program operations
5.6
Single Word Program method
The Single Word Program method is based on the Program command. It is supported only by Program Regions configured in the Control Program mode. If the Single Word Program method is attempted in a Program Region configured in the Object Program mode, the program operation is aborted and Status Register bits SR4 and SR8 are set. See Section 4: Command interface for a detailed description of the Program command. In Program Regions configured in the Control Program mode, the Program command can be issued several times. Using the Single Word Program method to program one or more bits to '0' in the 'B' halves of the Segments (A3 = 1), of an erased or already programmed Program Region, will generate an error:

in the case of an erased Program Region, it is considered an illegal operation that will set Status Register bits SR4 and SR9. in the case of an already programmed Program Region, an error is always generated because: - - to be able to write to a Program Region configured in the Object Program mode, the entire Block that contains the Program Region must be erased first. it is not allowed to write to the 'B' halves of the Segments of a Program Region configured in the Control Program mode.
5.7
Buffer Program method
The Buffer Program method is based on the Buffer Program command. It makes use of a 1KByte Write Buffer to speed up programming. The data is written to the Write Buffer and then programmed to the specified main array location. The Buffer Program method is supported whatever the program mode of the Program Regions. When using the Buffer Program method in a Program Region configured in the Object Program mode, the start address must be aligned to the 1KB Write Buffer. When using the Buffer Program method in a Program Region configured in the Control Program mode, the address to be programmed must be located inside the 'A' halves of the Program Region's Segments (addresses with A3 = 0) and the 'B' halves of the Segments (addresses with A3= 1) must be filled only with FFFFh data. The Buffer Program command can be issued several times to Program Regions configured in the Control Program mode. The Buffer Program command can be issued only once in Program Regions configured in the Object Program mode. Attempts to program the same Program Regions by re-issuing the Buffer Program command will lead to data corruption. See Section 4: Command interface for a detailed description of the Buffer Program command.

Program operations
M58PR256J, M58PR512J
5.8
Buffer Enhanced Factory Program method
The Buffer Enhanced Factory Program method is based on the Buffer Enhanced Factory Program command. The Buffer Enhanced Factory Program method is supported by the Program Regions regardless of the program mode they are configured in. In this program method, the Program Region (1KB) must be filled entirely, regardless of the Program mode used. If the size of the data to be written is less than 1KB, the remaining addresses in the Program Region must be filled with FFFFh. When using the Buffer Enhanced Factory Program method in a Program Region configured in the Control Program mode, the addresses to be programmed must be located in the 'A' half of the Program Regions' Segments (A3 = 0) and the 'B' half of the Segments (A3 = 1) must be filled only with FFFFh. See Section 4: Command interface for a detailed description of the Buffer Enhanced Factory Program command. Table 11. Program methods available with each Program mode

Status Register

Status Register
The Status Register provides information on the current or previous program or erase operations. Issue a Read Status Register command to read the contents of the Status Register, refer to Read Status Register Command section for more details. To output the contents, the Status Register is latched and updated on the falling edge of the Chip Enable or Output Enable signals and can be read until Chip Enable or Output Enable returns to VIH. The Status Register can only be read using single Asynchronous or Single Synchronous reads. Bus Read operations from any address within the bank, always read the Status Register during program and erase operations, if no Read Array command has been issued. The various bits convey information about the status and any errors of the operation. Bits SR7, SR6, SR2 and SR0 give information on the status of the device and are set and reset by the device. Bits SR9, SR8, SR5, SR4, SR3 and SR1 give information on errors, they are set by the device but must be reset by issuing a Clear Status Register command or a hardware reset. If an error bit is set to `1' the Status Register should be reset before issuing another command. The bits in the Status Register are summarized in Table 13: Status Register bits. Refer to Table 13 in conjunction with the following text descriptions.
6.1
Control Program Mode status bit (SR9)
The Control Program Mode Status Bit, SR9, is used to indicate whether an error occurred when writing to a Program Region configured in the Control Program mode. The SR9 bit should be read once the Program/Erase Controller Status bit SR7 is set to `1' (Program/Erase Controller inactive). SR9 is set to 1 when the user attempts to program Object data in a Control Mode region. When:

SR9 = 0, the program operation has completed successfully, SR9 = 1, the program operation failed.
Once set to `1', SR9 can only be cleared by issuing a Clear Status Register command or through a hardware reset. SR9 should be cleared before a new program command is issued, otherwise the new command will appear to fail.
45/114
Status Register
M58PR256J, M58PR512J
6.2
Object Program Mode status bit (SR8)
The Object Program Mode Status Bit, SR8, is used to indicate whether an error occurred when writing to a Program Region configured in the Object Program mode. The SR8 bit should be read once the Program/Erase Controller Status bit SR7 is set to `1' (Program/Erase Controller inactive). SR8 is set to 1 when the user attempts to rewrite an Object Mode region. When:

SR8 = 0, the program operation has completed successfully, SR8 = 1, the program operation failed.
Once set, SR8 can only be cleared by issuing a Clear Status Register command or through a hardware reset. SR8 should be cleared before a new program command is issued, otherwise the new command will appear to fail.
6.3
Program/Erase Controller status bit (SR7)
The Program/Erase Controller Status bit indicates whether the Program/Erase Controller is active or inactive in any bank. When:

SR7 = 0, the Program/Erase Controller is active, SR7 = 1, the Program/Erase Controller is inactive, and the device is ready to process a new command.
The Program/Erase Controller Status bit is set to '0' from immediately after a Program/Erase Suspend command is issued until the Program/Erase Controller pauses. After the Program/Erase Controller pauses the bit is set to '1'.
6.4
Erase Suspend status bit (SR6)
The Erase Suspend Status bit indicates that an erase operation has been suspended in the addressed Block. When:

SR6 = 0 no Program/Erase Suspend command has been issued, SR6 = 1 a Program/Erase Suspend command has been issued and the memory is waiting for a Program/Erase Resume command.
The Erase Suspend Status bit should only be considered valid when the Program/Erase Controller Status bit is set to '1' (Program/Erase Controller inactive). SR6 is set within the Erase Suspend Latency time of the Program/Erase Suspend command being issued, therefore the memory may still complete the operation rather than entering the Suspend mode. When a Program/Erase Resume command is issued the Erase Suspend Status bit is reset to '0'.
46/114
M58PR256J, M58PR512J
Status Register
6.5
Erase status bit (SR5)
The Erase Status bit is used to identify if there was an error during a Block Erase operation. When:

SR5 = 0 no error has occurred, SR5 = 1 the Program/Erase Controller has applied the maximum number of pulses to the Block or bank and still failed to verify that it has erased correctly.
The Erase Status bit should be read once the Program/Erase Controller Status bit is set to '1' (Program/Erase Controller inactive). Once set, the Erase Status bit must be cleared, by a Clear Status Register command or a hardware reset, before a new erase command is issued, otherwise the new command will appear to fail.
6.6
Program status bit (SR4)
The Program Status bit is used to identify if there was an error during a program operation. The Program Status bit should be read once the Program/Erase Controller Status bit is set to `1' (Program/Erase Controller inactive). When:

SR4 = 0, no error has occurred, SR4 = 1, the Program/Erase Controller has applied the maximum number of pulses to the Word and still failed to verify that it has programmed correctly.
Attempting to program a '1' to an already programmed bit while VPP = VPPH will also set the Program Status bit to '1'. If VPP is different from VPPH, SR4 remains set to '0' and the attempt is not shown. Once set to '1', the Program Status bit must be cleared, by a Clear Status Register command or a hardware reset, before a new program command is issued, otherwise the new command will appear to fail.
6.7
VPP status bit (SR3)
The VPP Status bit is used to identify an invalid voltage on the VPP pin during program and erase operations. The VPP pin is only sampled at the beginning of a program or erase operation. Program and erase operations are not guaranteed if VPP becomes invalid during an operation. When:

SR3 = 0, the voltage on the VPP pin was sampled at a valid voltage, SR3 = 1, the VPP pin has a voltage that is below the VPP Lockout Voltage, VPPLK, the memory is protected and program and erase operations cannot be performed.
Once set to `1', the VPP Status bit must be cleared by a Clear Status Register command or a hardware reset, before a new program or erase command is issued, otherwise the new command will appear to fail.

Status Register
M58PR256J, M58PR512J
6.8
Program Suspend status bit (SR2)
The Program Suspend Status bit indicates that a program operation has been suspended in the addressed Block. The Program Suspend Status bit should only be considered valid when the Program/Erase Controller Status bit is set to `1' (Program/Erase Controller inactive). When:

SR2 = 0, no Program/Erase Suspend command has been issued, SR2 = 1, a Program/Erase Suspend command has been issued and the memory is waiting for a Program/Erase Resume command.
SR2 is set within the Program Suspend Latency time of the Program/Erase Suspend command being issued, therefore the memory may still complete the operation rather than entering the Suspend mode. When a Program/Erase Resume command is issued the Program Suspend Status bit is reset to `0'.
6.9
Block Protection status bit (SR1)
The Block Protection Status bit is used to identify if a Program or Block Erase operation has tried to modify the contents of a locked Block. When:

SR1 = 0, no program or erase operation has been attempted on a locked Block, SR1 = 1, a program or erase operation has been attempted on a locked Block.
Once set to `1', the Block Protection Status bit must be cleared by a Clear Status Register command or a hardware reset, before a new program or erase command is issued, otherwise the new command will appear to fail.
6.10
Bank Write/Multiple Word Program status bit (SR0)
The Bank Write Status bit indicates if the addressed bank is programming or erasing. The Bank Write Status bit should only be considered valid when the Program/Erase Controller Status SR7 is set to `0'. When:

SR0 = 0 and SR7 = 0, the addressed bank is executing a program or erase operation. SR0 = 1 and SR7 = 0, a program or erase operation is being executed in a bank other than the one being addressed.
During Buffer Enhanced Factory Program operations the Multiple Word Program bit, SR0, shows if the device is ready to accept a new Word to be programmed to the memory array. When:

SR0 = 0, the device is ready for the next Word, SR0 = 1, the device is not ready for the next Word.

Configuration Register
The Configuration Register is used to configure the type of bus access that the memory will perform. Refer to Section 10: Read modes for details on read operations. The Configuration Register is set through the Command Interface using the Set Configuration Register command. The Configuration Register is volatile: after a reset or a power-down/power-up sequence, the register is set for Asynchronous Read (CR15=1) and all bits return to their default value. The Configuration Register bits are described in Table 15 They specify the selection of the burst length, burst X latency and the read operation. Refer to Figure 6 and Figure 7 for examples of synchronous burst configurations.
7.1
Read Select bit (CR15)
The Read Select bit, CR15, is used to switch between Asynchronous and Synchronous Read operations. When:
CR15 = 0: - - read operations in the Main Array are performed in Synchronous Burst mode; operations to read the Status Register, Electronic Signature, CFI and EFA are performed in Single Synchronous mode (See Section 10.3: Single Synchronous Read mode for details). read operations in the Main Array are performed in Asynchronous Page mode, operations to read the Status Register, Electronic Signature, CFI and EFA are performed in Asynchronous Random Access mode.
CR15 = 1: - -
Synchronous Burst Read can be performed across banks. On reset or power-up the Read Select bit is set to '1' for asynchronous access.
7.2
X-Latency bits (CR14-CR11)
The X-Latency bits are used during Synchronous Read operations to set the number of clock cycles between the address being latched and the first data becoming available. For correct operation the X-Latency bits can only assume the values in Table 15: Configuration Register. Table 14 shows how to set the X-Latency parameter, taking into account the frequency used to read the Flash memory in Synchronous mode. Refer to Figure 6: X-latency and data output configuration example, for an example waveform.

7.3
Wait Polarity bit (CR10)
The Wait Polarity bit is used to set the polarity of the Wait signal used in Synchronous Burst Read mode. When:

CR10 = 0, the Wait signal is active Low, CR10 = 1, the Wait signal is active High.
During Synchronous Burst Read mode the Wait signal indicates whether the data output are valid or a WAIT state must be inserted.
7.4
Wait Configuration bit (CR8)
The Wait Configuration bit is used to control the timing of the Wait output pin, WAIT, in Synchronous Burst Read mode. When:

CR8 = 0, the Wait output pin is asserted during the WAIT state, CR8 = 1, the Wait output pin is asserted one data cycle before the WAIT state.
When WAIT is asserted, Data is Not Valid and when WAIT is de-asserted, Data is Valid.
7.5
Burst length bits (CR2-CR0)
The Burst Length bits are used to set the number of Words to be output during a Synchronous Burst Read operation as result of a single address latch cycle. They can be set for 8 Words, 16 Words or continuous burst, where all the Words are read sequentially. In Continuous Burst mode the burst sequence can cross bank boundaries. In Continuous Burst mode, the device asserts the WAIT signal to indicate that a delay is necessary before the data is output. In Continuous Burst mode, if the starting address is not aligned to the 16 Word boundary, WAIT will be asserted when the burst sequence crosses the first 16 Word boundary to indicate that the device needs an internal delay to read the successive Words in the array. In the worst case, the number of WAIT states is one clock cycle less than the latency setting. WAIT will be asserted only once during a continuous burst access. See also Table 16: Burst type definition. CR9, CR7, CR6, CR5, CR4 and CR3 are reserved for future use.

Enhanced Configuration Register

Enhanced Configuration Register
The Enhanced Configuration Register (ECR) is used to enable the Deep Power Down mode and to configure the output driver strength. The Enhanced Configuration Register is set through the Command Interface using the Set Enhanced Configuration Register command. Its contents can be read by issuing the Read Electronic Signature command and then by reading from the Bank Base Address + 06h. The ECR is volatile: after a reset or a power-down/power-up sequence the register is set to the default value. The Configuration Register bits are described in Table 17
8.1
Deep Power-Down Mode bit (ECR15)
The Deep Power-Down Mode Bit, ECR15, is used to enable the Deep Power-Down mode. The device can only enter the Deep Power-Down mode from standby, by asserting the DPD pin and setting ECR15 to `1', whatever the order of the last two operations. When the device is in the Deep Power-Down mode, de-asserting the DPD pin and/or resetting ECR15 causes the device to revert to the Standby mode.
8.2
Deep Power-Down Polarity bit (ECR14)
The Deep Power-Down Polarity bit is used to set the polarity of the DPD signal. When:

ECR14 = 0, the DPD signal is active Low (default), ECR14 = 1, the DPD signal is active High.
8.3
Output Driver Control bits (ECR2-ECR0)
The Output Driver Control bits, ECR0, ECR1 and ECR2, are used to select the best suited output driver impedance to the system requirements. After reset or power-up the Output Driver Control bits are set to the Enhanced Configuration Register default value (ECR2-ECR0 = 100, that is 30W (30pF) (Default)). Optimum performance will be obtained only if the output driver impedance is configured properly. Once a configuration has been selected, all data and WAIT output drivers are set to the same setting. Table 17 gives the output driver impedances at VDDQ/2 and the loads that correspond for each ECR2-ECR0 bit configuration.

Extended Flash Array (EFA)

Extended Flash Array (EFA)
In addition to its Main Array, the M58PRxxxJ features an Extended Flash Array (EFA) divided into 4 Blocks of 4 KWords each. See Table 4: EFA memory map. The EFA Blocks are accessed through a separate set of commands (see Section 4: Command interface for details). The operations available on the EFA Blocks are Asynchronous Random Access Read, Single Synchronous Read, (Single Word) Program, Erase, Block Lock, Block Unlock, Block Lock-down. The EFA Blocks support Program/Erase Suspend and Dual Operations with Main Array. Dual Operations between the EFA and the OTP area are not supported. See Table 20: Dual operation limitations for details.
57/114
Read modes
M58PR256J, M58PR512J
10
Read modes
Read operations can be performed in two different ways depending on the settings in the Configuration Register. If the clock signal is `don't care' for the data output, the read operation is asynchronous; if the data output is synchronized with clock, the read operation is synchronous. The read mode and format of the data output are determined by the Configuration Register. (See Configuration Register section for details). All banks support both asynchronous and synchronous read operations.
10.1
Asynchronous Read mode
In Asynchronous Read operations the clock signal is `Don't Care'. The device outputs the data corresponding to the address latched, that is the memory array, Status Register, Common Flash Interface or Electronic Signature depending on the command issued. CR15 in the Configuration Register must be set to `1' for asynchronous operations. Asynchronous Read operations can be performed in two different ways, Asynchronous Random Access Read and Asynchronous Page Read. Only Asynchronous Page Read takes full advantage of the internal page storage so different timings are applied. In Asynchronous Read mode a Page of data is internally read and stored in a Page Buffer. The Page has a size of 16 Words and is addressed by address inputs A0, A1, A2 and A3. During the Page access, Amax-A4 and L must remain stable. The first Read operation within the Page has a longer access time (tAVQV, Random access time), subsequent reads within the same Page have much shorter access times (tAVQV1, Page access time). If the Page changes then the normal, longer timings apply again. Read operations to read Non-Array data (Status Register, Electronic Signature, CFI) should be performed in Asynchronous Single Word mode. If the Asynchronous Page mode is used to read Non-Array data, only the first output data will be valid, all subsequent data will be indeterminate. The Asynchronous Page Read mode is not available in the EFA. The device features an Automatic Standby mode. During Asynchronous Read operations, after a bus inactivity of 150ns, the device automatically switches to the Automatic Standby mode. In this condition the power consumption is reduced to the standby value and the outputs are still driven. In Asynchronous Read mode, the WAIT signal is always de-asserted. See Table 28: Asynchronous Read ac characteristics, Figure 10: Asynchronous random access Read ac waveforms, and Figure 11: Asynchronous Page Read ac waveforms, for details.
58/114
M58PR256J, M58PR512J
Read modes
10.2
Synchronous Burst Read mode
In Synchronous Burst Read mode the data is output in bursts synchronized with the clock. It is possible to perform burst reads across bank boundaries. Synchronous Burst Read mode can only be used to read the memory array. For other read operations, such as Read Status Register, Read CFI, Read Electronic Signature and Read EFA, Single Synchronous Read or Asynchronous Random Access Read must be used. In Synchronous Burst Read mode, the flow of the data output depends on parameters that are configured in the Configuration Register. A burst sequence starts at the first clock edge after the falling edge of Latch Enable or Chip Enable, whichever occurs last. Addresses are internally incremented and data is output on each data cycle after a delay which depends on the X latency bits CR14-CR11 of the Configuration Register. The number of Words to be output during a Synchronous Burst Read operation can be configured as 8 Words, 16 Words or Continuous (Burst Length bits CR2-CR0). The WAIT signal may be asserted to indicate to the system that an output delay will occur. This delay will depend on the starting address of the burst sequence and on the burst configuration. WAIT is asserted during the X latency, the WAIT state and at the end of a 8 and 16 Word burst. It is only de-asserted when output data are valid. In Continuous Burst Read mode, a WAIT state will occur when crossing the first 16 Word boundary if the start address is not 16 Word aligned. The WAIT signal can be configured to be active Low or active High by setting CR10 in the Configuration Register. See Table 29: Synchronous Read ac characteristics, and Figure 12: Synchronous Burst Read ac waveforms, for details.
10.3
Single Synchronous Read mode
Single Synchronous Read operations are similar to Synchronous Burst Read operations except that the memory outputs the same data until the burst length requirements are satisfied (according to Configuration Register bits CR2-CR0). Single Synchronous Read operations are used to read the EFA, Electronic Signature, Status Register, CFI, Block Protection Status, Configuration Register Status or Protection Register. When the addressed bank is in Read CFI, Read Status Register or Read Electronic Signature mode, the WAIT signal is asserted during the X latency, the WAIT state and at the end of a 4, 8 and 16 Word burst. It is only de-asserted when output data are valid. See Table 29: Synchronous Read ac characteristics, and Figure 12: Synchronous Burst Read ac waveforms, for details.

Dual operations and multiple bank architecture
M58PR256J, M58PR512J
11
Dual operations and multiple bank architecture
The Multiple Bank Architecture of the M58PRxxxJ gives greater flexibility for software developers to split the code and data spaces within the memory array. The Dual Operations feature simplifies the software management of the device by allowing code to be executed from one bank while another bank is being programmed or erased. The Dual Operations feature means that while programming or erasing in one bank, read operations are possible in another bank with zero latency (only one bank at a time is allowed to be in Program or Erase mode). If a Read operation is required in a bank, which is programming or erasing, the Program or Erase operation can be suspended. Also if the suspended operation was erase then a Program command can be issued to another Block, so the device can have one Block in Erase Suspend mode, one programming and other banks in Read mode. Bus Read operations are allowed in another bank between setup and confirm cycles of Program or Erase operations. By using a combination of these features, Read operations are possible at any moment in the M58PRxxxJ device. Dual operations between the Extended Flash Array (EFA) and either of the CFI, the OTP or the Electronic Signature memory space are not allowed. Table 20 shows which dual operations are allowed or not between the CFI, the OTP, the Electronic Signature locations and the memory array. Table 18 and Table 19 show the dual operations possible in other banks and in the same bank. Table 18. Dual operations allowed in other banks

Block locking
M58PR256J, M58PR512J
12
Block locking
The M58PRxxxJ features an instant, individual block locking scheme that allows any Block to be locked or unlocked with no latency. This locking scheme has three levels of protection.

Lock/Unlock - this first level allows software only control of block locking. Lock-Down - this second level requires hardware interaction before locking can be changed. VPP VPPLK - the third level offers a complete hardware protection against program and erase on all Blocks.
The protection status of each Block can be set to Locked, Unlocked, and Locked-Down. Table 21, defines all of the possible protection states (WP, DQ1, DQ0), and Appendix C, Figure 25, shows a flowchart for the locking operations.
12.1
Reading a block's lock status
The lock status of every Block can be read in the Read Electronic Signature mode of the device. To enter this mode issue the Read Electronic Signature command. Subsequent reads at the address specified in Table 9, will output the protection status of that Block. The lock status is represented by DQ0 and DQ1. DQ0 indicates the Block Lock/Unlock status and is set by the Lock command and cleared by the Unlock command. DQ0 is automatically set when entering Lock-Down. DQ1 indicates the Lock-Down status and is set by the Lock-Down command. DQ1 cannot be cleared by software, only by a hardware reset or power-down. The following sections explain the operation of the locking system.
12.2
Locked state
The default status of all Blocks on power-up or after a hardware reset is Locked (states (0,0,1) or (1,0,1)). Locked Blocks are fully protected from program or erase operations. Any program or erase operations attempted on a Locked Block will return an error in the Status Register. The Status of a Locked Block can be changed to Unlocked or Locked-Down using the appropriate software commands. An Unlocked Block can be Locked by issuing the Lock command.
12.3
Unlocked state
Unlocked Blocks (states (0,0,0), (1,0,0) (1,1,0)), can be programmed or erased. All unlocked Blocks return to the Locked state after a hardware reset or when the device is powereddown. The status of an unlocked Block can be changed to Locked or Locked-Down using the appropriate software commands. A locked Block can be unlocked by issuing the Unlock command.
62/114
M58PR256J, M58PR512J
Block locking
12.4
Lock-Down state
Blocks that are Locked-Down (state (0,1,x))are protected from program and erase operations (as for Locked Blocks) but their protection status cannot be changed using software commands alone. A Locked or Unlocked Block can be Locked-Down by issuing the Lock-Down command. Locked-Down Blocks revert to the Locked state when the device is reset or powered-down. The Lock-Down function is dependent on the Write Protect, WP, input pin. When WP=0 (VIL), the Blocks in the Lock-Down state (0,1,x) are protected from program, erase and protection status changes. When WP=1 (VIH) the Lock-Down function is disabled (1,1,x) and Locked-Down Blocks can be individually unlocked to the (1,1,0) state by issuing the software command, where they can be erased and programmed. When the Lock-Down function is disabled (WP=1) Blocks can be locked (1,1,1) and unlocked (1,1,0) as desired. When WP=0 Blocks that were previously Locked-Down return to the Lock-Down state (0,1,x) regardless of any changes that were made while WP=1. Device reset or power-down resets all Blocks, including those in Lock-Down, to the Locked state.
12.5
Locking operations during Erase Suspend
Changes to block lock status can be performed during an erase suspend by using the standard locking command sequences to unlock, lock or lock-down a Block. This is useful in the case when another Block needs to be updated while an erase operation is in progress. To change block locking during an erase operation, first write the Erase Suspend command, then check the Status Register until it indicates that the erase operation has been suspended. Next write the desired Lock command sequence to a Block and the lock status will be changed. After completing any desired lock, read, or program operations, resume the erase operation with the Erase Resume command. If a Block is locked or locked-down during an erase suspend of the same Block, the locking status bits will be changed immediately, but when the erase is resumed, the erase operation will complete. Locking operations cannot be performed during a program suspend.

1. The lock status is defined by the write protect pin and by DQ1 (`1' for a locked-down Block) and DQ0 (`1' for a locked Block) as read in the Read Electronic Signature command with A1 = VIH and A0 = VIL. 2. All Blocks are locked at power-up, so the default configuration is 001 or 101 according to WP status. 3. A WP transition to VIH on a locked Block will restore the previous DQ0 value, giving a 111 or 110.

Program and erase times and endurance cycles

Program and erase times and endurance cycles
The Program and Erase times and the number of Program/ Erase cycles per Block are shown in Table 22 Exact erase times may change depending on the memory array condition. The best case is when all the bits in the Block are at `0' (pre-programmed). The worst case is when all the bits in the Block are at `1' (not preprogrammed). Usually, the system overhead is negligible with respect to the erase time. In the M58PRxxxJ the maximum number of Program/Erase cycles depends on the VPP voltage supply used. Table 22.

Block address tables
The following set of equations can be used to calculate a complete set of Block addresses using the information contained in Tables 35, 36, 37 and 38. To calculate the Block Base Address from the Block Number: First it is necessary to calculate the Bank Number and the Block Number Offset. This can be achieved using the following formulas: For the M58PR256J: Bank_Number = Block_Number / 16 Block_Number_Offset = Block_Number - (Bank_Number x 16) For the M58PR512J: Bank_Number = Block_Number / 32 Block_Number_Offset = Block_Number - (Bank_Number x 32) The Block Base Address is calculated using the formula below: Block_Base_Address = Bank_Base_Address + Block_Base_Address_Offset To calculate the Bank Number and the Block Number from the Block Base Address: The Block Number, Bank Number and Block Number Offset can be calculated using the formulas below: For the M58PR256J: Block_Number = address / 216 Bank_Number = Block_Number / 16 Block_Number_Offset = Block_Number -(Bank_Number x 16) For the M58PR512J: Block_Number = address / 232 Bank_Number = Block_Number / 32 Block_Number_Offset = Block_Number -(Bank_Number x 32)

The Common Flash Interface is a JEDEC approved, standardized data structure that can be read from the Flash memory device. It allows a system software to query the device to determine various electrical and timing parameters, density information and functions supported by the memory. The system can interface easily with the device, enabling the software to upgrade itself when necessary. When the Read CFI Query Command is issued the device enters CFI Query mode and the data structure is read from the memory. Tables 39, 40, 41, 42, 43, 44, 45, 46, 47, 48 and 49 show the addresses used to retrieve the data. The Query data is always presented on the lowest order data outputs (DQ0-DQ7), the other outputs (DQ8-DQ15) are set to 0. The CFI data structure also contains a security area where a 64 bit unique security number is written (see Figure 4: Protection Register memory map). This area can be accessed only in Read mode by the final user. It is impossible to change the security number after it has been written by ST. Issue a Read Array command to return to Read mode.

WP = Word Program, BP = Buffer program, cmd = command, SR = Status Register, pgrm = program, IS = Illegal state, PS = Program suspend, ES = Erase suspend, CI = Command Interface, CR = Configuration Register, BEFP = Buffer Enhanced Factory Program, P/E. C. = Program/Erase Controller, WA0 = Address in a block different from first BEFP address, ECR = Enhanced Configuration Register. The output state shows the type of data that appears at the outputs if the bank address is the same as the command address. A bank can be placed in Read Array, Read Status Register, Read Electronic Signature or Read CFI mode, depending on the command issued. Each bank remains in its last output state until a new command is issued to that bank. The next state does not depend on the bank output state. At Power-Up, all banks are in Read Array mode. Issuing a Read Array command to a busy bank results in undetermined data output. The Clear Status Register command clears the Status Register error bits except when the P/E.C. is busy or suspended. BEFP is allowed only when Status Register bit SR0 is reset to `0'. BEFP is busy if the Block Address is the first BEFP Address. Any other commands are treated as data.

BEFP aborts when the Block Address is different from the first Block Address and data are FFFFh. BEFP Exit when Block Address is different from first Block Address and data are FFFFh. During BP setup, while entering the number of Words to be programmed and filling the buffer, the read status of the partition does not change. The BP confirm command changes the read status of the partition to Status Read. Illegal commands are commands not defined in the command set.
