M28W160ECT, M28W160ECB
SUMMARY DESCRIPTION
The M28W160EC is a 16 Mbit (1 Mbit x 16) nonvolatile Flash memory that can be erased electrically at the block level and programmed in-system on a Word-by-Word basis. These operations can be performed using a single low voltage (2.7 to 3.6V) supply. VDDQ allows to drive the I/O pin down to 1.65V. An optional 12V VPP power supply is provided to speed up customer programming. The device features an asymmetrical blocked architecture. The M28W160EC has an array of 39 blocks: 8 Parameter Blocks of 4 KWord and 31 Main Blocks of 32 KWord. M28W160ECT has the Parameter Blocks at the top of the memory address space while the M28W160ECB locates the Parameter Blocks starting from the bottom. The memory maps are shown in Figure 5., Block Addresses. The M28W160EC 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 powerup. Each block can be erased separately. Erase can be suspended in order to perform either read or 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. The device includes a 128 bit Protection Register and a Security Block to increase the protection of a system design. The Protection Register is divided into two 64 bit segments, the first one contains a unique device number written by Numonyx, while the second one is one-time-programmable by the user. The user programmable segment can be permanently protected. The Security Block, parameter block 0, can be permanently protected by the user. Figure 6., shows the Security Block and Protection Register Memory Map. Program and Erase commands are written to the Command Interface of the memory. An on-chip 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. The command set required to control the memory is consistent with JEDEC standards. The memory is offered in TSOP48 (10 X 20mm) and TFBGA46 (6.39 x 6.37mm, 0.75mm pitch) packages. In order to meet environmental requirements, Numonyx also offers the M28W160ECT and the M28W160ECB in ECOPACK(R) packages. ECOPACK packages are Lead-free. The category of second Level Interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. The memories are supplied with all the bits erased (set to '1').

SIGNAL DESCRIPTIONS
See Figure 2., Logic Diagram and Table 1., Signal Names, for a brief overview of the signals connected to this device. Address Inputs (A0-A19). 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 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 Write Bus operation. 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. 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, E, or Write Enable, W, 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 LockDown is enabled and the protection status of the block cannot be changed. When Write Protect is at VIH, the Lock-Down is disabled and the block can be locked or unlocked. (refer to Table 6., Read Protection Register and Lock Register). 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 minimized. After Reset all blocks are in the Locked state. When Reset is at VIH, the device is in normal operation. Exiting reset mode the device enters read array mode, but a negative transition of Chip Enable or a change of the address is required to ensure valid data outputs. V DD 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). V DDQ 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. V PP 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. The Supply Voltage VDD and the Program Supply Voltage VPP can be applied in any order. If VPP is kept in a low voltage range (0V to 3.6V) 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 Table 14., 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 11.4V to 12.6V it acts as a power supply pin. In this condition VPP must be stable until the Program/Erase algorithm is completed (see Table 16. and Table 17.). VSS Ground. VSS is the reference for all voltage measurements. Note: Each device in a system should have VDD, VDDQ and VPP decoupled with a 0.1F capacitor close to the pin. See Figure 8., AC Measurement Load Circuit. The PCB trace widths should be sufficient to carry the required VPP program and erase currents.

BUS OPERATIONS
There are six standard bus operations that control the device. These are Bus Read, Bus Write, Output Disable, Standby, Automatic Standby and Reset. See Table 2., Bus Operations, for a summary. Typically glitches of less than 5ns on Chip Enable or Write Enable are ignored by the memory and do not affect bus operations. Read. Read Bus 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 Figure 9., Read Mode AC Waveforms, and Table 15., Read AC Characteristics, for details of when the output becomes valid. Read mode is the default state of the device when exiting Reset or after power-up. Write. Bus Write operations write Commands to the memory or latch Input Data to be programmed. A 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. See Figures 10 and 11, Write AC Waveforms, and Tables 16 and 17, Write AC Characteristics, for details of the timing requirements. Output Disable. The data outputs are high impedance when the Output Enable is at VIH. Standby. Standby disables most of the internal circuitry allowing a substantial reduction of the current consumption. The memory is in stand-by when Chip Enable is at VIH and the device is in read mode. The power consumption is reduced to the stand-by level 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. Automatic Standby. Automatic Standby provides a low power consumption state during Read mode. Following a read operation, the device enters Automatic Standby after 150ns of bus inactivity even if Chip Enable is Low, VIL, and the supply current is reduced to IDD1. The data Inputs/Outputs will still output data if a bus Read operation is in progress. Reset. During Reset mode when Output Enable is Low, VIL, 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 Standby 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.

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 during, to monitor the progress of the operation, or the Program/Erase states. See APPENDIX D., Table 31., Write State Machine Current/Next, for a summary of the Command Interface. 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 reset the device to Read mode. Refer to Table 3., Commands, in conjunction with the text descriptions below. Read Memory Array Command The Read command returns the memory to its Read mode. One Bus Write cycle is required to issue the Read Memory Array command and return the memory to Read mode. Subsequent read operations will read the addressed location and output the data. When a device Reset occurs, the memory defaults to Read mode. Read Status Register Command The Status Register indicates when a program or erase operation is complete and the success or failure of the operation itself. Issue a Read Status Register command to read the Status Register's contents. Subsequent Bus Read operations read the Status Register at any address, until another command is issued. See Table 10., Status Register Bits, for details on the definitions of the bits. The Read Status Register command may be issued at any time, even during a Program/Erase operation. Any Read attempt during a Program/ Erase operation will automatically output the content of the Status Register. Read Electronic Signature Command The Read Electronic Signature command reads the Manufacturer and Device Codes and the Block Locking Status, or the Protection Register. The Read Electronic Signature command consists of one write cycle, a subsequent read will output the Manufacturer Code, the Device Code, the Block Lock and Lock-Down Status, or the Protection and Lock Register. See Tables 4, 5 and 6 for the valid address. Read CFI Query Command The Read Query Command is used to read data from the Common Flash Interface (CFI) Memory Area, allowing programming equipment or applications to automatically match their interface to the characteristics of the device. One Bus Write cycle is required to issue the Read Query Command. Once the command is issued subsequent Bus Read operations read from the Common Flash Interface Memory Area. See APPENDIX B., COMMON FLASH INTERFACE (CFI), Tables 25, 26, 27, 28, 29 and 30 for details on the information contained in the Common Flash Interface memory area. Block Erase Command The Block Erase command can be 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 Erase command. The second latches the block address in the internal state machine and starts the Program/ Erase Controller. If the second bus cycle is not Write Erase Confirm (D0h), Status Register bits b4 and b5 are set and the command aborts. Erase aborts if Reset turns to VIL. As data integrity cannot be guaranteed when the Erase operation is aborted, the block must be erased again. During Erase operations the memory will accept the Read Status Register command and the Program/Erase Suspend command, all other commands will be ignored. Typical Erase times are given in Table 7., Program, Erase Times and Program/Erase Endurance Cycles. See APPENDIX C., Figure 20., Erase Flowchart and Pseudo Code, for a suggested flowchart for using the Erase command. Program Command The memory array can be programmed word-byword. 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 the Data to be written and starts the Program/Erase Controller. During Program operations the memory will accept the Read Status Register command and the Program/Erase Suspend command. Typical Program times are given in Table 7., Program, Erase Times and Program/Erase Endurance Cycles.
11/50
M28W160ECT, M28W160ECB
Programming aborts if Reset goes to VIL. As data integrity cannot be guaranteed when the program operation is aborted, the block containing the memory location must be erased and reprogrammed. See APPENDIX C., Figure 17., Program Flowchart and Pseudo Code, for the flowchart for using the Program command. Double Word Program Command This feature is offered to improve the programming throughput, writing a page of two adjacent words in parallel.The two words must differ only for the address A0. Programming should not be attempted when VPP is not at VPPH. The command can be executed if VPP is below VPPH but the result is not guaranteed. Three bus write cycles are necessary to issue the Double Word Program command. The first bus cycle sets up the Double Word Program Command. The second bus cycle latches the Address and the Data of the first word to be written. The third bus cycle latches the Address and the Data of the second word to be written and starts the Program/Erase Controller. Read operations output the Status Register content after the programming has started. Programming aborts if Reset goes to VIL. As data integrity cannot be guaranteed when the program operation is aborted, the block containing the memory location must be erased and reprogrammed. See APPENDIX C., Figure 18., Double Word Program Flowchart and Pseudo Code, for the flowchart for using the Double Word Program command. Clear Status Register Command The Clear Status Register command can be used to reset bits 1, 3, 4 and 5 in the Status Register to `0'. One bus write cycle is required to issue the Clear Status Register command. The bits in the Status Register do not automatically return to `0' when a new Program or Erase command is issued. The error bits in the Status Register should be cleared before attempting a new Program or Erase command. Program/Erase Suspend Command The Program/Erase Suspend command is used to pause a Program or Erase operation. One bus write cycle is required to issue the Program/Erase command and pause the Program/Erase controller. During Program/Erase Suspend the Command Interface will accept the Program/Erase Resume, Read Array, Read Status Register, Read Electronic Signature and Read CFI Query commands. Additionally, if the suspend operation was Erase then the Program, Block Lock, Block Lock-Down or Protection Program commands will also be accepted. The block being erased may be protected by issuing the Block Protect, Block Lock or Protection Program commands. When the Program/ Erase Resume command is issued the operation will complete. Only the blocks not being erased may be read or programmed correctly. During a Program/Erase Suspend, the device can be placed in a pseudo-standby mode by taking Chip Enable to VIH. Program/Erase is aborted if Reset turns to VIL. See APPENDIX C., Figure 19., Program Suspend & Resume Flowchart and Pseudo Code, and Figure 21., Erase Suspend & Resume Flowchart and Pseudo Code, for flowcharts for using the Program/Erase Suspend command. Program/Erase Resume Command The Program/Erase Resume command can be used to restart the Program/Erase Controller after a Program/Erase Suspend operation has paused it. One Bus Write cycle is required to issue the command. Once the command is issued subsequent Bus Read operations read the Status Register. See APPENDIX C., Figure 19., Program Suspend & Resume Flowchart and Pseudo Code, and Figure 21., Erase Suspend & Resume Flowchart and Pseudo Code, for flowcharts for using the Program/Erase Resume command. Protection Register Program Command The Protection Register Program command is used to Program the 64 bit user One-Time-Programmable (OTP) segment of the Protection Register. The segment is programmed 16 bits at a time. When shipped all bits in the segment are set to `1'. The user can only program the bits to `0'. Two 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 the Data to be written to the Protection Register and starts the Program/Erase Controller. Read operations output the Status Register content after the programming has started. The segment can be protected by programming bit 1 of the Protection Lock Register. Bit 1 of the Protection Lock Register protects bit 2 of the Protection Lock Register. Programming bit 2 of the Protection Lock Register will result in a permanent protection of the Security Block (see Figure 6., Security Block and Protection Register Memory Map). Attempting to program a previously protected Protection Register will result in a Status

M28W160ECT, M28W160ECB
Register error. The protection of the Protection Register and/or the Security Block is not reversible. The Protection Register Program cannot be suspended. See APPENDIX C., Figure 23., Protection Register Program Flowchart and Pseudo Code, for the flowchart for using the Protection Register Program command. 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 at 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. The lock status can be monitored for each block using the Read Electronic Signature command. Table 9. shows the protection status after issuing a Block Lock command. The Block Lock bits are volatile, once set they remain set until a hardware reset or power-down/ power-up. They are cleared by a Blocks Unlock command. Refer to the section, Block Locking, for a detailed explanation. Block Unlock Command The Blocks 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 Blocks Unlock command. The first bus cycle sets up the Block Unlock command. The second Bus Write cycle latches the block address. The lock status can be monitored for each block using the Read Electronic Signature command. Table 9. shows the protection status after issuing a Block Unlock command. Refer to the section, Block Locking, for a detailed explanation. Block Lock-Down Command A locked block cannot be Programmed or Erased, or have its protection status 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 command. The second Bus Write cycle latches the block address. 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 9. shows the protection status after issuing a Block Lock-Down command. Refer to the section, Block Locking, for a detailed explanation.

BLOCK LOCKING
The M28W160EC 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 softwareonly 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 lock status of each block can be set to Locked, Unlocked, and Lock-Down. Table 9., defines all of the possible protection states (WP, DQ1, DQ0), and APPENDIX C., Figure 22., 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 write 90h to the device. Subsequent reads at the address specified in Table 5., will output the lock 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. It is also automatically set when entering Lock-Down. DQ1 indicates the Lock-Down status and is set by the Lock-Down command. It 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 after a hardware reset is Locked (states (0,0,1) or (1,0,1)). Locked blocks are fully protected from any program or erase. 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 Lock-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 unlocked 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 lock 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 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 (1,1,1) 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. These blocks can then be locked again (1,1,1) and unlocked (1,1,0) as desired while WP remains high. When WP is low, blocks that were previously Locked-Down return to the LockDown state (0,1,x) regardless of any changes made while WP was high. Device reset or powerdown resets all blocks, including those in LockDown, 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 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 protection 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. Refer to APPENDIX D., COMMAND INTERFACE AND PROGRAM/ ERASE CONTROLLER STATE, for detailed information on which commands are valid during erase suspend.

Note: 1. The protection 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.

M28W160ECT, M28W160ECB
STATUS REGISTER
The Status Register provides information on the current or previous Program or Erase operation. The various bits convey information and errors on the operation. To read the Status register the Read Status Register command can be issued, refer to Read Status Register Command section. To output the contents, the Status Register is latched 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. Either Chip Enable or Output Enable must be toggled to update the latched data. Bus Read operations from any address always read the Status Register during Program and Erase operations. The bits in the Status Register are summarized in Table 10., Status Register Bits. Refer to Table 10. in conjunction with the following text descriptions. Program/Erase Controller Status (Bit 7). The Program/Erase Controller Status bit indicates whether the Program/Erase Controller is active or inactive. 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 Program/Erase Controller is inactive, and the device is ready to process a new command. The Program/Erase Controller Status is Low immediately after a Program/Erase Suspend command is issued until the Program/Erase Controller pauses. After the Program/Erase Controller pauses the bit is High. During Program, Erase, operations the Program/ Erase Controller Status bit can be polled to find the end of the operation. Other bits in the Status Register should not be tested until the Program/Erase Controller completes the operation and the bit is High. After the Program/Erase Controller completes its operation the Erase Status, Program Status, VPP Status and Block Lock Status bits should be tested for errors. Erase Suspend Status (Bit 6). The Erase Suspend Status bit indicates that an Erase operation has been suspended or is going to be suspended. 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 Program/Erase Resume command. The Erase Suspend Status should only be considered valid when the Program/Erase Controller Status bit is High (Program/Erase Controller inactive). Bit 7 is set within 30s 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 returns Low. Erase Status (Bit 5). The Erase Status bit can be used to identify if the memory has failed to verify that the block has erased correctly. When the Erase Status bit is High (set to `1'), the Program/ Erase Controller has applied the maximum number of pulses to the block and still failed to verify that the block has erased correctly. The Erase Status bit should be read once the Program/Erase Controller Status bit is High (Program/Erase Controller inactive). Once set High, the Erase Status bit can only be reset Low by a Clear Status Register command or a hardware reset. If set High it should be reset before a new Program or Erase command is issued, otherwise the new command will appear to fail. Program Status (Bit 4). The Program Status bit is used to identify a Program failure. When the Program Status bit is High (set to `1'), the Program/Erase Controller has applied the maximum number of pulses to the byte and still failed to verify that it has programmed correctly. The Program Status bit should be read once the Program/Erase Controller Status bit is High (Program/Erase Controller inactive). Once set High, the Program Status bit can only be reset Low by a Clear Status Register command or a hardware reset. If set High it should be reset before a new command is issued, otherwise the new command will appear to fail. VPP Status (Bit 3). The VPP Status bit can be 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. Indeterminate results can occur if VPP becomes invalid during an operation. When the VPP Status bit is Low (set to `0'), the voltage 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 Program and Erase operations cannot be performed. Once set High, the VPP Status bit can only be reset Low by a Clear Status Register command or a hardware reset. If set High it should be reset before a new Program or Erase command is issued, otherwise the new command will appear to fail. Program Suspend Status (Bit 2). The Program Suspend Status bit indicates that a Program operation has been suspended. 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 Program/Erase Resume command. The Program Suspend Status should only be considered valid when the Pro-

gram/Erase Controller Status bit is High (Program/ Erase Controller inactive). Bit 2 is set within 5s 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 returns Low. Block Protection Status (Bit 1). The Block Protection Status bit can be used to identify if a Program or 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 attempted on a locked block. Once set High, the Block Protection Status bit can only be reset Low by a Clear Status Register command or a hardware reset. If set High it should be reset before a new command is issued, otherwise the new command will appear to fail. Reserved (Bit 0). Bit 0 of the Status Register is reserved. Its value must be masked. Note: Refer to APPENDIX C., Flowcharts and Pseudo Codes, for using the Status Register.
