M58LR128FT, M58LR128FB SUMMARY DESCRIPTION The M58LR128FT/B is a 128 Mbit (8Mbit x16) non-volatile Flash memory that may be erased electrically at block level and programmed in-sys- tem on a Word-by-Word basis using a 1.7V to 2.0V VDD supply for the circuitry and a 1.7V to 2.0V VDDQ supply for the Input/Output pins. An optional 9V VPP power supply is provided to speed up fac- tory programming. The device features an asymmetrical block archi- tecture and is based on a multi-level cell technolo- gy. M58LR128FT/B has an array of 131 blocks, and is divided into 8 Mbit banks. There are 15 banks each containing 8 main blocks of 64 KWords, and one parameter bank containing 4 pa- rameter blocks of 16 KWords and 7 main blocks of 64 KWords. 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 4. The Param- eter Blocks are located at the top of the memory address space for the M58LR128FT, and at the bottom for the M58LR128FB. Each block can be erased separately. Erase can be suspended, in order to perform program in any other block, and then resumed. Program can be suspended to read data in any other block and then resumed. Each block can be programmed and erased over 100,000 cycles using the supply voltage V DD . There is a Buffer Enhanced Factory programming command available to speed up pro- gramming. Program and erase commands are written to the Command Interface of the memory. An internal Program/Erase Controller takes care of the tim- ings 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 stan- dards. 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 fre- quencies of up to 54MHz. The Synchronous Burst Read operation can be suspended and resumed. The device features an Automatic Standby mode. When the bus is inactive during Asynchronous Read operations, the device automatically switch- es to the Automatic Standby mode. In this condi- tion the power consumption is reduced to the standby value and the outputs are still driven. The M58LR128FT/B features an instant, individual block locking scheme that allows any block to be locked or unlocked with no latency, enabling in- stant code and data protection. All blocks have three levels of protection. They can be locked and locked-down individually preventing any acciden- tal programming or erasure. There is an additional hardware protection against program and erase. When V PP ≤ VPPLK all blocks are protected against program or erase. All blocks are locked at power- up. The device includes 17 Protection Registers and 2 Protection Register locks, one for the first Protec- tion 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 segments: a 64 bit segment containing a unique device number written by ST, and a 64 bit segment One-Time-Programmable (OTP) by the user. The user programmable segment can be permanently protected. Figure 5., shows the Pro- tection Register Memory Map. The memory is available in a VFBGA56, 7.7x9mm, 0.75 pitch package and is supplied with all the bits erased (set to ’1’).

M58LR128FT, M58LR128FB SIGNAL DESCRIPTIONS See Figure 2., Logic Diagram and Table 1., Signal Names , for a brief overview of the signals connect- ed to this device. Address Inputs (A0-A22). The Address Inputs select the cells in the memory array to access dur- ing Bus Read operations. During Bus Write opera- tions they control the commands sent to the Command Interface of the internal state machine. Data Input/Output (DQ0-DQ15). The Data I/O outputs the data stored at the selected address during a Bus Read operation or inputs a command or the data to be programmed during a Bus Write operation. Chip Enable (E ). The Chip Enable input acti- vates the memory control logic, input buffers, de- coders 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. Output Enable (G ).The Output Enable controls data outputs during the Bus Read operation of the memory. Write Enable (W).The Write Enable 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. 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 Locked-Down blocks cannot be changed. When Write Protect is at VIH, the Lock-Down is disabled and the Locked-Down blocks can be locked or un- locked. (refer to Table 14., Lock Status). Reset (RP). The Reset input provides a hard- ware 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 re- duced to the Reset Supply Current IDD2 . Refer to Table 19., DC Characteristics - Currents, for the value of IDD2. After Reset all blocks are in the Locked state and the Configuration Register is re- set. When Reset is at VIH, the device is in normal operation. Exiting reset mode the device enters asynchronous read mode, but a negative transi- tion of Chip Enable or Latch Enable is required to ensure valid data outputs. The Reset pin can be interfaced with 3V logic with- out any additional circuitry. It can be tied to VRPH (refer to Table 20., DC Characteristics - Voltages). Latch Enable (L).Latch Enable latches the ad- dress bits on its rising edge. The address latch is transparent when Latch Enable is at V IL and it is inhibited when Latch Enable is at V IH. Latch Enable can be kept Low (also at board level) when the Latch Enable function is not required or supported. Clock (K).The clock input synchronizes the memory to the microcontroller during synchronous read operations; the address is latched on a Clock edge (rising or falling, according to the configura- tion settings) when Latch Enable is at VIL. Clock is ignored during asynchronous read and in write op- erations. 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 imped- ance 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 clock cycle in advance. 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). VDDQ Supply Voltage.VDDQ provides the power supply to the I/O pins and enables all Outputs to be powered independently from VDD . VDDQ can be tied to VDD or can use a separate supply. VPP Program Supply Voltage.VPP is both a control input and a power supply pin. The two functions are selected by the voltage range ap- plied 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 volt- age lower than VPPLK gives an absolute protection against program or erase, while VPP > VPP1 en- ables these functions (see Tables 19 and 20, 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 op- erations continue. If VPP is in the range of VPPH it acts as a power supply pin. In this condition VPP must be stable un- til the Program/Erase algorithm is completed. VSS Ground. VSS ground is the reference for the core supply. It must be connected to the system ground. 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 V DD , VDDQ and VPP decoupled with a 0.1µF ce- ramic capacitor close to the pin (high frequen- cy, inherently low inductance capacitors

Register, and the Configuration Register.

M58LR128FT, M58LR128FB Status of the addressed bank, the Protection Reg- ister, or the Configuration Register (see Table 7.). The Read Electronic Signature command can be issued at any time, even during program or erase operations, except during Protection Register Pro- gram operations. If a Read Electronic Signature command is issued to a bank that is executing a program or erase op- eration the bank will go into Read Electronic Sig- nature mode. Subsequent Bus Read cycles will output the Electronic Signature data and the Pro- gram/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 Elec- tronic Signature. A Read Array command is re- quired to return the bank to Read Array mode. 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 read from the Common Flash Inter- face. The Read CFI Query command can be issued at any time, even during program or erase opera- tions. 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. Subse- quent 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 Asyn- chronous Read and Single Synchronous Read op- erations should be used to read from the CFI. A Read Array command is required to return the bank to Read Array mode. See APPENDIX B., COMMON FLASH INTER- FACE , Tables 31, 32, 33, 34, 35, 37, 38, 39 and 40 for details on the information contained in the Common Flash Interface memory area. Clear Status Register Command The Clear Status Register command can be used to reset (set to ‘0’) all error bits (SR1, 3, 4 and 5) in the Status Register. One Bus Write cycle is required to issue the Clear Status Register command. The Clear Status Reg- ister command does not change the read mode of the addressed bank. The error bits in the Status Register do not auto- matically return to ‘0’ when a new command is is- sued. The error bits in the Status Register should be cleared before attempting a new program or erase command. 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 Con- firm 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 opera- tion within the addressed bank will output the con- tents of the Status Register. A Read Array command is required to return the bank to Read Array mode. During Block Erase operations the bank contain- ing the block being erased will only accept the Read Array, Read Status Register, Read Electron- ic 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 guaran- teed when the Block Erase operation is aborted, the block must be erased again. Refer to Dual Operations section for detailed infor- mation about simultaneous operations allowed in banks not being erased. Typical Erase times are given in Table 15., Program, Erase Times and Endurance Cy- cles. See APPENDIX C. , Figure 25., Block Erase Flow- chart and Pseudo Code, for a suggested flowchart for using the Block Erase command. Program Command The program command is used to program a sin- gle Word to the memory array. Two Bus Write cycles are required to issue the Program Command. ■ The first bus cycle sets up the Program command.

M58LR128FT, M58LR128FB ■ The second latches the address and data to be programmed and starts the Program/Erase Controller. Once the programming has started, read opera- tions in the bank being programmed output the Status Register content. During a Program operation, the bank containing the Word being programmed will only accept the Read Array, Read Status Register, Read Electron- ic Signature, Read CFI Query and the Program/ Erase Suspend command, all other commands will be ignored. A Read Array command is re- quired to return the bank to Read Array mode. Refer to Dual Operations section for detailed infor- mation about simultaneous operations allowed in banks not being programmed. Typical Program times are given in Table 15., Program, Erase Times and Endurance Cy- cles. 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 22., Program Flow- chart and Pseudo Code, for the flowchart for using the Program command. Buffer Program Command The Buffer Program Command makes use of the device’s 32-Word Write Buffer to speed up pro- gramming. Up to 32 Words can be loaded into the Write Buffer. The Buffer Program command dra- matically reduces in-system programming time compared to the standard non-buffered Program command. Four successive steps are required to issue the Buffer Program command. 1. The first Bus Write cycle sets up the Buffer Program command. The setup code can be addressed to any location within the targeted block. After the first Bus Write cycle, read operations in the bank will output the contents of the Status Register. Status Register bit SR7 should be read to check that the buffer is available (SR7 = 1). If the buffer is not available (SR7 = 0), re-issue the Buffer Program command to update the Status Register contents. 2. 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. 3. 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. Optimum performance is obtained when the start address corresponds to a 32 Word boundary. If the start address is not aligned to a 32 word boundary, the total programming time is doubled 4. The final Bus Write cycle confirms the Buffer Program command and starts the program operation. All the addresses used in the Buffer Program op- eration must lie within the same block. 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 oper- ation without affecting the data in the memory ar- ray. If the Status Register bits SR4 and SR5 are set to '1', the Buffer Program Command is not accepted. Clear the Status Register before re-issuing the command. If the block being programmed is protected an er- ror will be set in the Status Register and the oper- ation 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 infor- mation about simultaneous operations allowed in banks not being programmed. See Appendix C, figure 27, Buffer Program Flow- chart 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 pro- gramming in manufacturing environments where the programming time is critical. It is used to program one or more Write Buffer(s) of 32 Words to a block. 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 block. Only one block can be programmed at a time. 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 25°C ± 5°C ■ The targeted block must be unlocked ■ The start address must be aligned with the start of a 32 Word buffer boundary

M58LR128FT, M58LR128FB ■ The address must remain the Start Address throughout programming. Dual operations are not supported during the Buff- er Enhanced Factory Program operation and the command cannot be suspended. 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 7. Factory Program Com- mands for detail information. Refer to Table 6., Factory Program Command, and Figure 29., Buffer Enhanced Factory Program Flowchart and Pseudo Code. Setup Phase.The Buffer Enhanced Factory Pro- gram 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 opera- tions 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 opera- tion is terminated. See Status Register section for details on the error. Program and Verify Phase.The Program and Verify Phase requires 32 cycles to program the 32 Words to the Write Buffer. The data is stored se- quentially, starting at the first address of the Write Buffer, until the Write Buffer is full (32 Words). To program less than 32 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 com- mand. 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. 2. 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. 3. Once the Write Buffer is full, the data is pro- grammed sequentially to the memory array. After the program operation the device auto- matically verifies the data and reprograms if necessary. The Program and Verify phase can be repeated, without re-issuing the command, to program addi- tional 32 Word locations as long as the address re- mains in the same block. 4. Finally, after all Words, or the entire block have been programmed, write one Bus Write operation to any address outside the block containing the Start Address, to terminate Program and Verify Phase. Status Register bit SR0 must be checked to deter- mine 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. Exit Phase.Status Register P/E.C. bit SR7 set to ‘1’ indicates that the device has exited the Buffer Enhanced Factory Program operation and re- turned to Read Status Register mode. 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 15.. See APPENDIX C. , Figure 29., Buffer Enhanced Factory Program Flowchart and Pseudo Code, for a suggested flowchart on using the Buffer En- hanced Factory Program command. 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 re- quired to restart the suspended operation. One bus write cycle is required to issue the Pro- gram/Erase Suspend command. Once the Pro- gram/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 Pro- gram/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

M58LR128FT, M58LR128FB – Read CFI Query. Additionally, if the suspended operation was erase then the following commands are also accepted: – Clear Status Register – Program (except in erase-suspended block) – Block Lock – Block Lock-Down – Block Unlock. 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 oper- ations. 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 re- sumed until the program operation has completed. The Program/Erase Suspend command does not change the read mode of the banks. If the sus- pended bank was in Read Status Register, Read Electronic signature or Read CFI Query mode the bank remains in that mode and outputs the corre- sponding data. Refer to Dual Operations section for detailed infor- mation 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 V IH. Program/erase is aborted if Reset, RP, goes to VIL. See APPENDIX C. , Figure 24., Program Suspend & Resume Flowchart and Pseudo Code, and Fig- ure 26., Erase Suspend & Resume Flowchart and Pseudo Code , for flowcharts for using the Pro- gram/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 sus- pended bank was in Read Status Register, Read Electronic signature or Read CFI Query mode the bank remains in that mode and outputs the corre- sponding data. If a Program command is issued during a Block Erase Suspend, then the erase cannot be re- sumed until the program operation has completed. See APPENDIX C. , Figure 24., Program Suspend & Resume Flowchart and Pseudo Code, and Fig- ure 26., Erase Suspend & Resume Flowchart and Pseudo Code , for flowcharts for using the Pro- gram/Erase Resume command. Protection Register Program Command The Protection Register Program command is used to program the user One-Time-Programma- ble (OTP) segments of the Protection Register and the two Protection Register Locks. The device features 16 OTP segments of 128 bits and one OTP segment of 64 bits, as shown in Fig- ure 5., Protection Register Memory Map. The segments are programmed one Word at a time. When shipped all bits in the segment 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 pro- gram operation has started. Attempting to program a previously protected Pro- tection Register will result in a Status Register er- ror. The Protection Register Program cannot be sus- pended. The two Protection Register Locks are used to protect the OTP segments from further modifica- tion. The protection of the OTP segments is not re- versible. Refer to Figure 5., Protection Register Memory Map , and Table 8., Protection Register Locks, for details on the Lock bits. See APPENDIX C. , Figure 28., Protection Regis- ter Program Flowchart and Pseudo Code, for a flowchart for using the Protection Register Pro- gram 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

M58LR128FT, M58LR128FB 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 de- tails. 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 V IH. 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. The various bits convey information about the sta- tus 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 SR5, SR4, SR3 and SR1 give information on er- rors, 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 9., Status Register Bits. Refer to Table 9. in conjunction with the following text descriptions. 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 the Program/Erase Controller Status bit is Low (set to ‘0’), the Program/Erase Controller is active; when the bit is High (set to ‘1’), the Pro- gram/Erase Controller is inactive, and the device is ready to process a new command. The Program/Erase Controller Status bit is Low immediately after a Program/Erase Suspend com- mand is issued until the Program/Erase Controller pauses. After the Program/Erase Controller paus- es the bit is High. Erase Suspend Status Bit (SR6).The Erase Suspend Status bit indicates that an erase opera- tion has been suspended in the addressed block. When the Erase Suspend Status bit is High (set to ‘1’), a Program/Erase Suspend command has been issued and the memory is waiting for a Pro- gram/Erase Resume command. The Erase Suspend Status bit should only be con- sidered valid when the Program/Erase Controller Status bit is High (Program/Erase Controller inac- tive). SR6 is set within the Erase Suspend Latency time of the Program/Erase Suspend command be- ing issued therefore the memory may still com- plete the operation rather than entering the Suspend mode. When a Program/Erase Resume command is is- sued the Erase Suspend Status bit returns Low. Erase Status Bit (SR5).The Erase Status bit is used to identify if there was an error during a block or bank erase operation. When the Erase Status bit is High (set to ‘1’), the Program/Erase Control- ler 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 Pro- gram/Erase Controller Status bit is High (Program/ Erase Controller inactive). Once set High, the Erase Status bit must be set Low by a Clear Status Register command or a hardware reset before a new erase command is is- sued, otherwise the new command will appear to fail. 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 High (Pro- gram/Erase Controller inactive). When the Program Status bit is High (set to ‘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 pro- grammed bit while V PP = VPPH will also set the Program Status bit High. If VPP is different from VPPH , SR4 remains Low (set to '0') and the attempt is not shown. Once set High, the Program Status bit must be set Low 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. 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 oper- ation. When the VPP Status bit is Low (set to ‘0’), the volt- age on the VPP pin was sampled at a valid voltage. when the VPP Status bit is High (set to ‘1’), the VPP pin has a voltage that is below the VPP Lockout Voltage, VPPLK , the memory is protected and pro- gram and erase operations cannot be performed. Once set High, the VPP Status bit must be set Low by a Clear Status Register command or a hard- ware reset before a new program or erase com- mand is issued, otherwise the new command will appear to fail.

M58LR128FT, M58LR128FB Program Suspend Status Bit (SR2).The Pro- gram 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 High (Program/Erase Con- troller inactive). When the Program Suspend Status bit is High (set to ‘1’), a Program/Erase Suspend command has been issued and the memory is waiting for a Pro- gram/Erase Resume command. SR2 is set within the Program Suspend Latency time of the Program/Erase Suspend command be- ing issued therefore the memory may still com- plete the operation rather than entering the Suspend mode. When a Program/Erase Resume command is is- sued the Program Suspend Status bit returns Low. Block Protection Status Bit (SR1).The Block Protection Status bit is used to identify if a Pro- gram or Block Erase operation has tried to modify the contents of a locked block. When the Block Protection Status bit is High (set to ‘1’), a program or erase operation has been at- tempted on a locked block. Once set High, the Block Protection Status bit must be set Low by a Clear Status Register com- mand or a hardware reset before a new program or erase command is issued, otherwise the new command will appear to fail. Bank Write/Multiple Word Program Status Bit (SR0).The Bank Write Status bit indicates wheth- er the addressed bank is programming or erasing. In Buffer Enhanced Factory Program mode the Multiple Word Program bit shows if the device is ready to accept a new Word to be programmed to the memory array. The Bank Write Status bit should only be consid- ered valid when the Program/Erase Controller Sta- tus SR7 is Low (set to ‘0’). When both the Program/Erase Controller Status bit and the Bank Write Status bit are Low (set to ‘0’), the addressed bank is executing a program or erase operation. When the Program/Erase Con- troller Status bit is Low (set to ‘0’) and the Bank Write Status bit is High (set to ‘1’), a program or erase operation is being executed in a bank other than the one being addressed. In Buffer Enhanced Factory Program mode if Mul- tiple Word Program Status bit is Low (set to ‘0’), the device is ready for the next Word, if the Multi- ple Word Program Status bit is High (set to ‘1’) the device is not ready for the next Word. For further details on how to use the Status Regis- ter, see the Flowcharts and Pseudocodes provid- ed in APPENDIX C.

Table 9. Status Register Bits Note: Logic level '1' is High, '0' is Low.

M58LR128FT, M58LR128FB CONFIGURATION REGISTER The Configuration Register is used to configure the type of bus access that the memory will per- form. Refer to Read Modes section for details on read operations. The Configuration Register is set through the Command Interface using the Set Configuration Register command. After a reset or power-up the device is configured for asynchronous read (CR15 = 1). The Configuration Register bits are described in Table 10. They specify the selection of the burst length, burst type, burst X latency and the read op- eration. Refer to Figures 6 and 7 for examples of synchronous burst configurations. Read Select Bit (CR15) The Read Select bit, CR15, is used to switch be- tween Asynchronous and Synchronous Read op- erations. When the Read Select bit is set to ’1’, read opera- tions are asynchronous; when the Read Select bit is set to ’0’, read operations are synchronous. Synchronous Burst Read is supported in both pa- rameter and main blocks and can be performed across banks. On reset or power-up the Read Select bit is set to ’1’ for asynchronous access (default). X-Latency Bits (CR13-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 10., Configuration Register. The correspondence between X-Latency settings and the maximum sustainable frequency must be calculated taking into account some system pa- rameters. Two conditions must be satisfied: 1. Depending on whether t AVK_CPU or tDELAY is supplied either one of the following two equations must be satisfied: (n + 1) tK ≥ tAVQV - tAVK_CPU + tQVK_CPU (n + 2) tK ≥ tAVQV + tDELAY + tQVK_CPU 2. and also tK > tKQV + tQVK_CPU where ■ n is the chosen X-Latency configuration code ■ tK is the clock period ■ tAVK_CPU is clock to address valid, L Low, or E Low, whichever occurs last ■ tDELAY is address valid, L Low, or E Low to clock, whichever occurs last ■ tQVK_CPU is the data setup time required by the system CPU, ■ tKQV is the clock to data valid time ■ tAVQV is the random access time of the device. Refer to Figure 6., X-Latency and Data Output Configuration Example. Wait Polarity Bit (CR10) The Wait Polarity bit is used to set the polarity of the Wait signal used in Synchronous Burst Read mode. During Synchronous Burst Read mode the Wait signal indicates whether the data output are valid or a WAIT state must be inserted. When the Wait Polarity bit is set to ‘0’ the Wait sig- nal is active Low. When the Wait Polarity bit is set to ‘1’ the Wait signal is active High (default). Data Output Configuration Bit (CR9) The Data Output Configuration bit is used to con- figure the output to remain valid for either one or two clock cycles during synchronous mode. When the Data Output Configuration Bit is ’0’ the output data is valid for one clock cycle, when the Data Output Configuration Bit is ’1’ the output data is valid for two clock cycles. The Data Output Configuration must be config- ured using the following condition: ■ tK > tKQV + tQVK_CPU where ■ tK is the clock period ■ tQVK_CPU is the data setup time required by the system CPU ■ tKQV is the clock to data valid time. If this condition is not satisfied, the Data Output Configuration bit should be set to ‘1’ (two clock cy- cles). Refer to Figure 6., X-Latency and Data Out- put Configuration Example. Wait Configuration Bit (CR8) The Wait Configuration bit is used to control the timing of the Wait output pin, WAIT, in Synchro- nous Burst Read mode. When WAIT is asserted, Data is Not Valid and when WAIT is deasserted, Data is Valid. When the Wait Configuration bit is Low (set to ’0’) the Wait output pin is asserted during the wait state. When the Wait Configuration bit is High (set to ’1’) (default) the Wait output pin is asserted one clock cycle before the wait state. Burst Type Bit (CR7) The Burst Type bit determines the sequence of ad- dresses read during Synchronous Burst Reads. The Burst Type bit is High (set to ’1’), as the mem- ory outputs from sequential addresses only.

M58LR128FT, M58LR128FB See Table 11., Burst Type Definition, for the se- quence of addresses output from a given starting address in sequential mode. Valid Clock Edge Bit (CR6) The Valid Clock Edge bit, CR6, is used to config- ure the active edge of the Clock, K, during syn- chronous read operations. When the Valid Clock Edge bit is Low (set to ’0’) the falling edge of the Clock is the active edge. When the Valid Clock Edge bit is High (set to ’1’) the rising edge of the Clock is the active edge. Wrap Burst Bit (CR3) The Wrap Burst bit, CR3, is used to select be- tween wrap and no wrap. Synchronous burst reads can be confined inside the 4, 8 or 16 Word boundary (wrap) or overcome the boundary (no wrap). When the Wrap Burst bit is Low (set to ‘0’) the burst read wraps. When it is High (set to ‘1’) the burst read does not wrap. 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 4 Words, 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, in 4, 8 or 16 Words no- wrap, depending on the starting address, the de- vice asserts the WAIT signal to indicate that a de- lay is necessary before the data is output. If the starting address is aligned to a 4 Word boundary no wait states are needed and the WAIT output is not asserted. If the starting address is shifted by 1, 2 or 3 posi- tions from the four word boundary, WAIT will be asserted for 1, 2 or 3 clock cycles 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. WAIT will be asserted only once during a continuous burst access. See also Table 11., Burst Type Definition. CR14, CR5 and CR4 are reserved for future use.

M58LR128FT, M58LR128FB READ MODES Read operations can be performed in two different ways depending on the settings in the Configura- tion Register. If the clock signal is ‘don’t care’ for the data output, the read operation is asynchro- nous; 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 synchro- nous read operations. Asynchronous Read Mode In Asynchronous Read operations the clock signal is ‘don’t care’. The device outputs the data corre- sponding to the address latched, that is the mem- ory array, Status Register, Common Flash Interface or Electronic Signature depending on the command issued. CR15 in the Configuration Reg- ister must be set to ‘1’ for asynchronous opera- tions. Asynchronous Read operations can be performed in two different ways, Asynchronous Random Ac- cess 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 in- ternally read and stored in a Page Buffer. The Page has a size of 4 Words and is addressed by address inputs A0 and A1. The first read operation within the Page has a longer access time (t AVQV , 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. 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 deasserted. See Table 21., Asynchronous Read AC Charac- teristics, Figure 10., Asynchronous Random Ac- cess Read AC Waveforms , and Figure 11., Asynchronous Page Read AC Waveforms, for details. Synchronous Burst Read Mode In Synchronous Burst Read mode the data is out- put in bursts synchronized with the clock. It is pos- sible to perform burst reads across bank boundaries. Synchronous Burst Read mode can only be used to read the memory array. For other read opera- tions, such as Read Status Register, Read CFI and Read Electronic Signature, Single Synchro- nous 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 con- figured in the Configuration Register. A burst sequence starts at the first clock edge (ris- ing or falling depending on Valid Clock Edge bit CR6 in the Configuration Register) 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 CR13-CR11 of the Configuration Register. The number of Words to be output during a Syn- chronous Burst Read operation can be configured as 4 Words, 8 Words, 16 Words or Continuous (Burst Length bits CR2-CR0). The data can be configured to remain valid for one or two clock cy- cles (Data Output Configuration bit CR9). The order of the data output can be modified through the Wrap Burst bit in the Configuration Register. The burst sequence is sequential and can be confined inside the 4, 8 or 16 Word bound- ary (Wrap) or overcome the boundary (No Wrap). The WAIT signal may be asserted to indicate to the system that an output delay will occur. This de- lay 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 4, 8 and 16 Word burst. It is only deasserted when output data are valid. In Continuous Burst Read mode a Wait state will oc- cur when crossing the first 16 Word boundary. If the burst starting address is aligned to a 4 Word Page, the Wait state will not occur. The WAIT signal can be configured to be active Low or active High by setting CR10 in the Config- uration Register. See Table 22., Synchronous Read AC Character- istics, and Figure 12., Synchronous Burst Read AC Waveforms, for details. Synchronous Burst Read Suspend.A Syn- chronous Burst Read operation can be suspend- ed, freeing the data bus for other higher priority devices. It can be suspended during the initial ac- cess latency time (before data is output) in which case the initial latency time can be reduced to ze- ro, or after the device has output data. When the Synchronous Burst Read operation is suspended, internal array sensing continues and any previous- ly latched internal data is retained. A burst se-

M58LR128FT, M58LR128FB quence can be suspended and resumed as often as required as long as the operating conditions of the device are met. A Synchronous Burst Read operation is suspend- ed when Chip Enable, E, is Low and the current address has been latched (on a Latch Enable ris- ing edge or on a valid clock edge). The Clock sig- nal is then halted at VIH or at VIL, and Output Enable, G, goes High. When Output Enable, G, becomes Low again and the Clock signal restarts, the Synchronous Burst Read operation is resumed exactly where it stopped. WAIT will revert to high-impedance when Output Enable, G, or Chip Enable, E, goes High. See Table 22., Synchronous Read AC Character- istics, and Figure 14., Synchronous Burst Read Suspend AC Waveforms, for details. Single Synchronous Read Mode Single Synchronous Read operations are similar to Synchronous Burst Read operations except that the memory outputs the same data to the end of the operation. Synchronous Single Reads are used to read the 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 as- serted during the X latency, the Wait state and at the end of a 4, 8 and 16 Word burst. It is only deas- serted when output data are valid. See Table 22., Synchronous Read AC Character- istics, and Figure 12., Synchronous Burst Read AC Waveforms, for details.

M58LR128FT, M58LR128FB BLOCK LOCKING The M58LR128FT/B 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 14., defines all of the possible protection states (WP DQ1, DQ0), and APPENDIX C. , Figure 27., shows a flowchart for the locking operations. 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 Signa- ture command. Subsequent reads at the address specified in Table 7., will output the protection sta- tus 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 Un- lock command. DQ0 is automatically set when en- tering 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. Locked State The default status of all blocks on power-up or af- ter 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. 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 powered-down. The status of an unlocked block can be changed to Locked or Locked-Down using the appropriate software commands. A locked block can be un- locked by issuing the Unlock command. 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 can- not 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 dis- abled (1,1,x) and Locked-Down blocks can be in- dividually 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 previ- ously 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, in- cluding those in Lock-Down, to the Locked state. 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 opera- tion, 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 complet- ing any desired lock, read, or program operations, resume the erase operation with the Erase Re- sume 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.

Table 14. Lock Status in the Read Electronic Signature command with A1 = VIH and A0 = VIL.

1. All blocks are locked at power-up, so the default configuration is 001 or 101 according to WP status.
2. A WP transition to VIH on a locked block will restore the previous DQ0 value, giving a 111 or 110.
