Preliminary USER MODE DEFINITIONS
Word / Byte Configuration
EN29GL064
The BYTE# pin controls whether the device data I/O pins operate in the byte or word configuration. If the BYTE# pin is set at logic `1', the device is in word configuration, DQ0-DQ15 are active and controlled by CE# and OE#. If the BYTE# pin is set at logic `0', the device is in byte configuration, and only data I/O pins DQ0-DQ7 are active and controlled by CE# and OE#. The data I/O pins DQ8-DQ14 are tri-stated, and the DQ15 pin is used as an input for the LSB (A-1) address function.
VIO Control
The VIO allows the host system to set the voltage levels that the device generates and tolerates on all inputs and outputs (address, control, and DQ signals). VIO range is 1.65 to VCC. For example, a VIO of 1.65-3.6 volts allows for I/O at the 1.65 or 3.6 volt levels, driving and receiving signals to and from other 1.65 or 3.6 V devices on the same data bus. Only 48-pin TSOP package does not offer VIO function.
Read
All memories require access time to output array data. In a read operation, data is read from one memory location at a time. Addresses are presented to the device in random order, and the propagation delay through the device causes the data on its outputs to arrive with the address on its inputs. The device defaults to reading array data after device power-up or hardware reset. To read data from the memory array, the system must first assert a valid address on A21-A0, while driving OE# and CE# to VIL. WE# must remain at VIH. All addresses are latched on the falling edge of CE#. Data will appear on DQ15-DQ0 after address access time (tACC), which is equal to the delay from stable addresses to valid output data.The OE# signal must be driven to VIL. Data is output on DQ15-DQ0 pins after the access time (tOE) has elapsed from the falling edge of OE#, assuming the tACC access time has been meet.
Page Read Mode
The device is capable of fast page mode read and is compatible with the page mode Mask ROM read operation. This mode provides faster read access speed for random locations within a page. The page size of the device is 8 words/16 bytes. The appropriate page is selected by the higher address bits A21A3. Address bits A2-A0 in word mode (A2 to A-1 in byte mode) determine the specific word within a page. The microprocessor supplies the specific word location. The random or initial page access is equal to tACC or tCE and subsequent page read accesses (as long as the locations specified by the microprocessor falls within that page) is equivalent to tPACC. When CE# is deasserted and reasserted for a subsequent access, the access time is tACC or tCE. Fast page mode accesses are obtained by keeping the "read-page addresses" constant and changing the "intraread page" addresses.
Autoselect
The Autoselect mode provides manufacturer ID, Device identification, and sector protection information, through identifier codes output from the internal register (separate from the memory array) on DQ7-DQ0. This mode is primarily intended for programming equipment to automatically match a device to be programmed with its corresponding programming algorithm. The Autoselect codes can also be accessed in-system. There are two methods to access autoselect codes. One uses the autoselect command, the other applies VID on address pin A9. When using programming equipment, the autoselect mode requires VID (8.5 V to 9.5 V) on address pin

A9. Address pins must be as shown in Table 4. * To access Autoselect mode without using high voltage on A9, the host system must issue the Autoselect command. * The Autoselect command sequence may be written to an address within a sector that is either in the read or erase-suspend-read mode. * The Autoselect command may not be written while the device is actively programming or erasing. * The system must write the reset command to return to the read mode (or erase-suspend-read mode if the sector was previously in Erase Suspend). * It is recommended that A9 apply VID after power-up sequence is completed. In addition, it is recommended that A9 apply from VID to VIH/VIL before power-down the VCC / VIO. * When verifying sector protection, the sector address must appear on the appropriate highest order address bits. The remaining address bits are don't care. When all necessary bits have been set as required, the programming equipment may then read the corresponding identifier code on DQ15DQ0. The Autoselect codes can also be accessed in-system through the command register.
Program/Erase Operations
These devices are capable of several modes of programming and or erase operations which are described in detail in the following sections. During a write operation, the system must drive CE# and WE# to VIL and OE# to VIH when providing address, command, and data. Addresses are latched on the last falling edge of WE# or CE#, while data is latched on the 1st rising edge of WE# or CE#. The Accelerated Program mode allows the host system to send program commands to the Flash device without first writing unlock cycles within the command sequence. Note the following: * When the Embedded Program algorithm is complete, the device returns to the read mode. * The system can determine the status of the program operation by reading the DQ status bits. Refer to the Write Operation Status on page 20 for information on these status bits. * An "0" cannot be programmed back to a "1." A succeeding read shows that the data is still "0." * Only erase operations can convert a "0" to a "1." * Any commands written to the device during the Embedded Program/Erase are ignored except the Suspend commands. * Secured Silicon Sector, Autoselect, and CFI functions are unavailable when a program operation is in progress. * A hardware reset and/or power removal immediately terminates the Program/Erase operation and the Program/Erase command sequence should be reinitiated once the device has returned to the read mode to ensure data integrity. * Programming is allowed in any sequence and across sector boundaries for single word programming operation. * Programming to the same word address multiple times without intervening erases is permitted.
Single Word Programming
Single word programming mode is one method of programming the Flash. In this mode, four Flash command write cycles are used to program an individual Flash address. The data for this programming operation could be 8 or 16-bits wide. While the single word programming method is supported by most devices, in general Single Word Programming is not recommended for devices that support Write Buffer Programming. When the Embedded Program algorithm is complete, the device then returns to the read mode and addresses are no longer latched. The system can determine the status of the program operation by reading the DQ status bits. * During programming, any command (except the Suspend Program command) is ignored. * The Secured Silicon Sector, Autoselect, and CFI functions are unavailable when a program operation is in progress.

Write Buffer Programming
EN29GL064
Write Buffer Programming allows the system to write a maximum of 16 words in one programming operation. This results in a faster effective word programming time than the standard "word" programming algorithms. The Write Buffer Programming command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the Write Buffer Load command written at the Sector Address in which programming occurs. At this point, the system writes the number of "word locations minus 1" that are loaded into the page buffer at the Sector Address in which programming occurs. This tells the device how many write buffer addresses are loaded with data and therefore when to expect the "Program Buffer to Flash" confirm command. The number of locations to program cannot exceed the size of the write buffer or the operation aborts. (Number loaded = the number of locations to program minus 1. For example, if the system programs 6 address locations, then 05h should be written to the device.) The system then writes the starting address/data combination. This starting address is the first address/data pair to be programmed, and selects the "write-buffer-page" address. All subsequent address/data pairs must fall within the elected-write-buffer-page. The "write-buffer-page" is selected by using the addresses A21-A5. The "write-buffer-page" addresses must be the same for all address/data pairs loaded into the write buffer. (This means Write Buffer Programming cannot be performed across multiple "write-bufferpages." This also means that Write Buffer Programming cannot be performed across multiple sectors. If the system attempts to load programming data outside of the selected "write-buffer-page", the operation ABORTs.) After writing the Starting Address/Data pair, the system then writes the remaining address/data pairs into the write buffer. Note that if a Write Buffer address location is loaded multiple times, the "address/data pair" counter is decremented for every data load operation. Also, the last data loaded at a location before the "Program Buffer to Flash" confirm command is the data programmed into the device. It is the software's responsibility to comprehend ramifications of loading a write-buffer location more than once. The counter decrements for each data load operation, NOT for each unique write-buffer-address location. Once the specified number of write buffer locations have been loaded, the system must then write the "Program Buffer to Flash" command at the Sector Address. Any other address/data write combinations abort the Write Buffer Programming operation. The Write Operation Status bits should be used while monitoring the last address location loaded into the write buffer. This eliminates the need to store an address in memory because the system can load the last address location, issue the program confirm command at the last loaded address location, and then check the write operation status at that same address. DQ7, DQ6, DQ5, DQ2, and DQ1 should be monitored to determine the device status during Write Buffer Programming. The write-buffer "embedded" programming operation can be suspended using the standard suspend/resume commands. Upon successful completion of the Write Buffer Programming operation, the device returns to READ mode. The Write Buffer Programming Sequence is ABORTED under any of the following conditions: * Load a value that is greater than the page buffer size during the "Number of Locations to Program" step. * Write to an address in a sector different than the one specified during the Write-Buffer-Load command. * Write an Address/Data pair to a different write-buffer-page than the one selected by the "Starting Address" during the "write buffer data loading" stage of the operation. * Writing anything other than the Program to Buffer Flash Command after the specified number of "data load" cycles. The ABORT condition is indicated by DQ1 = 1, DQ7 = DATA# (for the "last address location loaded"), DQ6 = TOGGLE, DQ5 = 0. This indicates that the Write Buffer Programming Operation was ABORTED.

A "Write-to- Buffer-Abort reset" command sequence is required when using the write buffer Programming features in Unlock Bypass mode. Note that the Secured Silicon sector, autoselect, and CFI functions are unavailable when a program operation is in progress. Write buffer programming is allowed in any sequence of memory (or address) locations. These flash devices are capable of handling multiple write buffer programming operations on the same write buffer address range without intervening erases. Use of the write buffer is strongly recommended for programming when multiple words are to be programmed.

Sector Erase
EN29GL064
Sector erase is a six bus cycle operation. The sector erase command sequence is initiated by writing two un-lock cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the address of the sector to be erased, and the sector erase command. The Command Definitions table shows the address and data requirements for the sector erase command sequence. Once the sector erase operation has begun, only the Sector Erase Suspend command is valid. All other commands are ignored. If there are several sectors to be erased, Sector Erase Command sequences must be issued for each sector. That is, only a sector address can be specified for each Sector Erase command. Users must issue another Sector Erase command for the next sector to be erased after the previous one is completed. When the Embedded Erase algorithm is completed, the device returns to reading array data and addresses are no longer latched. The system can determine the status of the erase operation by using DQ7, DQ6, or DQ2. Refer to "Write Operation Status" for information on these status bits. Flowchart 4 illustrates the algorithm for the erase operation. Refer to the Erase/Program Operations tables in the "AC Characteristics" section for parameters, and to the Sector Erase Operations Timing diagram for timing waveforms.

Chip Erase Command Sequence
EN29GL064
Chip erase is a six-bus cycle operation as indicated by Table 14-1. These commands invoke the Embedded Erase algorithm, which does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire memory to an all zero data pattern prior to electrical erase. After a successful chip erase, all locations of the chip contain FFFFh. The system is not required to provide any controls or timings during these operations. When the Embedded Erase algorithm is complete, that sector returns to the read mode and addresses are no longer latched. The system can determine the status of the erase operation by using DQ7 or DQ6/DQ2. Refer to "Write Operation Status" for information on these status bits. Any commands written during the chip erase operation are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the chip erase command sequence should be reinitiated once that sector has returned to reading array data, to ensure the entire array is properly erased.
Erase Suspend/Erase Resume Commands
The Erase Suspend command allows the system to interrupt a sector erase operation and then read data from, or program data to, any sector not selected for erasure. The sector address is required when writing this command. This command is valid only during the sector erase operation. The Sector Erase Suspend command is ignored if written during the chip erase operation or Embedded Program algorithm. Addresses are don't-cares when writing the Sector Erase Suspend command. When the Erase Suspend command is written during the sector erase operation, the device requires a maximum of 20 s to suspend the erase operation. After the erase operation has been suspended, the device enters the erase-suspend-read mode. The system can read data from or program data to any sector not selected for erasure. (The device "erase suspends" all sectors selected for erasure.) Reading at any address within erase-suspended sectors produces status information on DQ7-DQ0. The system can use DQ7, or DQ6, and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. After an erase-suspended program operation is complete, the device returns to the erase-suspend-read mode. The system can determine the status of the program operation using write operation status bits, just as in the standard program operation. In the erase-suspend-read mode, the system can also issue the Autoselect command sequence. Refer to Write Buffer Programming on page 15 and the Autoselect on page 12 for details. To resume the sector erase operation, the system must write the Erase Resume command. The address of the erase-suspended sector is required when writing this command. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the chip has resumed erasing.
Program Suspend/Program Resume Commands
The Program Suspend command allows the system to interrupt an embedded programming operation or a "Write to Buffer" programming operation so that data can read from any non-suspended sector. When the Program Suspend command is written during a programming process, the device halts the programming operation within 15 s maximum (5 s typical) and updates the status bits. Addresses are "don't-cares" when writing the Program Suspend command. After the programming operation has been suspended, the system can read array data from any nonsuspended sector. The Program Suspend command may also be issued during a programming operation while an erase is suspended. In this case, data may be read from any addresses not within a sector in Erase Suspend or Program Suspend. If a read is needed from the Secured Silicon Sector area, then user must use the proper command sequences to enter and exit this region. The system may also write the Autoselect Command Sequence when the device is in Program Suspend

mode. The device allows reading Autoselect codes in the suspended sectors, since the codes are not stored in the memory array. When the device exits the Autoselect mode, the device reverts to Program Suspend mode, and is ready for another valid operation. After the Program Resume command is written, the device reverts to programming. The system can determine the status of the program operation using the write operation status bits, just as in the standard program operation. The system must write the Program Resume command (address bits are "don't care") to exit the Program Suspend mode and continue the programming operation. Further writes of the Program Resume command are ignored. Another Program Suspend command can be written after the device has resumed programming.
Accelerated Program
Accelerated single word programming and write buffer programming operations are enabled through the WP#/ACC pin. This method is faster than the standard program command sequences. If the system asserts VHH on this input, the device automatically enters the Accelerated Program mode and uses the higher voltage on the input to reduce the time required for program operations. The system can then use the Write Buffer Load command sequence provided by the Accelerated Program mode. Note that if a "Write-to-Buffer-Abort Reset" is required while in Accelerated Program mode, the full 3-cycle RESET command sequence must be used to reset the device. Removing VHH from the ACC input, upon completion of the embedded program operation, returns the device to normal operation. * Sectors must be unlocked prior to raising WP#/ACC to VHH. * The WP#/ACC pin must not be at VHH for operations other than accelerated programming, or device damage may result. * It is recommended that WP#/ACC apply VHH after power-up sequence is completed. In addition, it is recommended that WP#/ACC apply from VHH to VIH/VIL before powering down VCC/ VIO . (check VHH VID both have or not)
Write Operation Status
The device provides several bits to determine the status of a program or erase operation. The following subsections describe the function of DQ1, DQ2, DQ3, DQ5, DQ6, and DQ7.
DQ7: Data# Polling
The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Program or Erase algorithm is in progress or completed, or whether the device is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the command sequence. Note that the Data# Polling is valid only for the last word being programmed in the write-buffer-page during Write Buffer Programming. Reading Data# Polling status on any word other than the last word to be programmed in the write-bufferpage returns false status information. During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When the Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program address falls within a protected sector, Data# polling on DQ7 is active, then that sector returns to the read mode. During the Embedded Erase Algorithm, Data# polling produces a "0" on DQ7. When the Embedded Erase algorithm is complete, or if the device enters the Erase Suspend mode, Data# Polling produces a "1" on DQ7. The system must provide an address within any of the sectors selected for erasure to read valid status information on DQ7. After an erase command sequence is written, if all sectors selected for erasing are protected, Data#

EN29GL064
Polling on DQ7 is active for approximately 100 s, then the device returns to the read mode. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. However, if the system reads DQ7 at an address within a protected sector, the status may not be valid. Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with DQ6-DQ0 while Output Enable (OE#) is asserted low. That is, the device may change from providing status information to valid data on DQ7. Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device has completed the program or erase operation and DQ7 has valid data, the data outputs on DQ6-DQ0 may be still invalid. Valid data on DQ7-D00 appears on successive read cycles.

DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete, or whether the device has entered the Erase Suspend mode. Toggle Bit I may be read at any address, and is valid after the rising edge of the final WE# pulse in the command sequence (prior to the program or erase operation), and during the sector erase time-out. During an Embedded Program or Erase algorithm operation, successive read cycles to any address that is being programmed or erased causes DQ6 to toggle. When the operation is complete, DQ6 stops toggling. After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for approximately 100 s, then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erase

erase 2suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6 toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use DQ7. If a program address falls within a protected sector, DQ6 toggles for approximately 1 s after the program command sequence is written, then returns to reading array data. DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program Algorithm is complete. Toggle Bit I on DQ6 requires either OE# or CE# to be de-asserted and reasserted to show the change in state.
DQ2: Toggle Bit II
The "Toggle Bit II" on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that is, the Embedded Erase algorithm is in progress), or whether that sector is erasesuspended. Toggle Bit II is valid after the rising edge of the final WE# pulse in the command sequence. DQ2 toggles when the system reads at addresses within those sectors that have been selected for erasure. But DQ2 cannot distinguish whether the sector is actively erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sector and mode information.
Reading Toggle Bits DQ6/DQ2
Whenever the system initially begins reading toggle bit status, it must read DQ7-DQ0 at least twice in a row to determine whether a toggle bit is toggling. Typically, the system would note and store the value of the toggle bit after the first read. After the second read, the system would compare the new value of the toggle bit with the first. If the toggle bit is not toggling, the device has completed the program or erases operation. The system can read array data on DQ7-DQ0 on the following read cycle. However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note whether the value of DQ5 is high. If it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5 went high. If the toggle bit is no longer toggling, the device has successfully completed the program or erases operation. If it is still toggling, the device did not complete the operation successfully, and the system must write the reset command to return to reading array data. The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not gone high. The system may continue to monitor the toggle bit and DQ5 through successive read cycles, determining the status as described in the previous paragraph. Alternatively, it may choose to perform other system tasks. In this case, the system must start at the beginning of the algorithm when it returns to determine the status of the operation. Note When verifying the status of a write operation (embedded program/erase) of a memory sector, DQ6 and DQ2 toggle between high and low states in a series of consecutive and contiguous status read cycles. In order for this toggling behavior to be properly observed, the consecutive status bit reads must not be interleaved with read accesses to other memory sectors. If it is not possible to temporarily prevent reads to other memory sectors, then it is recommended to use the DQ7 status bit as the alternative method of determining the active or inactive status of the write operation.
DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under these conditions DQ5 produces a "1," indicating that the program or erase cycle was not successfully completed. The device does not output a 1 on DQ5 if the system tries to program a 1 to a location that was previously programmed to 0. Only an erase operation can change a 0 back to a 1. Under this condition, the device ignores the bit that was incorrectly instructed to be programmed from a 0 to a 1, while any other bits that were correctly requested to be changed from 1 to 0 are programmed. Attempting to program a 0 to a 1 is masked during the programming operation. Under valid DQ5 conditions, the system must write the reset command to return to the read mode (or to the erasesuspend-read mode if a sector was previously in the erase-suspend-program mode).

DQ3: Sector Erase Timeout State Indicator
EN29GL064
After writing a sector erase command sequence, the output on DQ3 can be checked to determine whether or not an erase operation has begun. (The sector erase timer does not apply to the chip erase command.) When sector erase starts, DQ3 switches from "0" to "1". This device does not support multiple sector erase (continuous sector erase) command sequences so it is not very meaningful since it immediately shows as a "1" after the first 30h command. Future devices may support this feature.
DQ1: Write to Buffer Abort
DQ1 indicates whether a Write to Buffer operation was aborted. Under these conditions DQ1 produces a "1". The system must issue the "Write to Buffer Abort Reset" command sequence to return the device to reading array data.

Writing Commands/Command Sequences
During a write operation, the system must drive CE# and WE# to VIL and OE# to VIH when providing an address, command, and data. Addresses are latched on the last falling edge of WE# or CE#, while data is latched on the 1st rising edge of WE# or CE#. An erase operation can erase one sector or the entire device. Table 3 indicate the address space that each sector occupies. The device address space is divided into uniform 32KW/64KB sectors. A sector address is the set of address bits required to uniquely select a sector. ICC2 in "DC Characteristics" represents the active current specification for the write mode. "AC Characteristics" contains timing specification tables and timing diagrams for write operations.

RY/BY#
EN29GL064
The RY/BY# is a dedicated, open-drain output pin that indicates whether an Embedded Algorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in the command sequence. Since RY/BY# is an open-drain output, several RY/BY# pins can be tied together in parallel with a pull-up resistor to VCC. This feature allows the host system to detect when data is ready to be read by simply monitoring the RY/BY# pin, which is a dedicated output and controlled by CE# (not OE#).
Hardware Reset
The RESET# input provides a hardware method of resetting the device to reading array data. When RESET# is driven low for at least a period of tRP (RESET# Pulse Width), the device immediately terminates any operation in progress, tristates all outputs, resets the configuration register, and ignores all read/write commands for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. To ensure data integrity Program/Erase operations that were interrupted should be reinitiated once the device is ready to accept another command sequence. When RESET# is held at VSS, the device draws VCC reset current (ICC5). If RESET# is held at VIL, but not at VSS, the standby current is greater. RESET# may be tied to the system reset circuitry which enables the system to read the boot-up firmware from the Flash memory upon a system reset.
Software Reset
Software reset is part of the command set that also returns the device to array read mode and must be used for the following conditions: 1. To exit Autoselect mode 2. When DQ5 goes high during write status operation that indicates program or erase cycle was not successfully completed 3. Exit sector lock/unlock operation. 4. To return to erase-suspend-read mode if the device was previously in Erase Suspend mode. 5. After any aborted operations The following are additional points to consider when using the reset command: * This command resets the sectors to the read and address bits are ignored. * Reset commands are ignored during program and erase operations. * The reset command may be written between the cycles in a program command sequence before programming begins (prior to the third cycle). This resets the sector to which the system was writing to the read mode. * If the program command sequence is written to a sector that is in the Erase Suspend mode, writing the reset command returns that sector to the erase-suspend-read mode. * The reset command may be written during an Autoselect command sequence. * If a sector has entered the Autoselect mode while in the Erase Suspend mode, writing the reset command returns that sector to the erase-suspend-read mode. * If DQ1 goes high during a Write Buffer Programming operation, the system must write the "Write to Buffer Abort Reset" command sequence to RESET the device to reading array data. The standard RESET command does not work during this condition.

programmed in the EON factory. When the device is programmed to disable all PPB erase command, DQ3 outputs a `0', when the lock register bits are read. Similarly, if the device is programmed to enable all PPB erase command, DQ3 outputs a `1' when the lock register bits are read. Likewise the DQ4 bit is also programmed in the EON Factory. DQ4 is the bit which indicates whether Volatile Sector Protection Bit (DYB) is protected or not after boot-up. When the device is programmed to set all Volatile Sector Protection Bit protected after power-up, DQ4 outputs a `0' when the lock register bits are read. Similarly, when the device is programmed to set all Volatile Sector Protection Bit unprotected after power-up, DQ4 outputs a `1'. Each of these bits in the lock register are non-volatile. DQ15- DQ5 are reserved and will be 1's.

Notes: After the Lock Register Bits Command Set Entry command sequence is written, reads and writes for Sector 0 are disabled, while reads from other sectors are allowed until exiting this mode. After selecting a sector protection method, each sector can operate in any of the following three states: 1. Constantly locked: The selected sectors are protected and can not be reprogrammed unless PPB lock bit is cleared via hardware reset, or power cycle. 2. Dynamically locked: The selected sectors are protected and can be altered via software commands. 3. Unlocked: The sectors are unprotected and can be erased and/or programmed.
Persistent Protection Bits
The Persistent Protection Bits are unique and nonvolatile. For uniform sector device, Sector 0~3 and 124~127 have one PPB for each sectors and for Sector 4~123 have one PPB every four sectors. For bottom boot sector device, Sector 0~123 are 1 PPB per 4 sectors and Sector 124~134 have PPB for each boot sector. For top boot sector device, Sector 0~10 have PPB for each boot sector and Sector 11~134 are 1 PPB per 4 sectors(refer to Figure 8a, 8b, 8c and Table 3a, 3b, 3c). The PPB has the same endurances as the Flash memory. Preprogramming and verification prior to erasure are handled by the device, and therefore do not require system monitoring. Notes 1. Each PPB is individually programmed and all are erased in parallel. 2. While programming PPB for the four sectors, array data can be read from any other sector, except Sector 0 (used for Data# Polling) and the sector in which sector PPB is being programmed. 3. Entry command disables reads and writes for the sector selected. 4. Reads within that sector return the PPB status for that sector. 5. All Reads must be performed using the read mode. 6. The specific sector address are written at the same time as the program command. 7. If the PPB Lock Bit is set, the PPB Program or erase command does not execute and times-out without programming or erasing the PPB. 8. There are no means for individually erasing a specific PPB and no specific sector address is required for this operation. 9. Exit command must be issued after the execution which resets the device to read mode and reenables reads and writes for Sector 0. 10. The programming state of the PPB for given sectors can be verified by writing a PPB Status Read Command to the device as described by the flow chart shown in Figure 9.

Dynamic Protection Bits
EN29GL064
Dynamic Protection Bits are volatile and unique for each sector and can be individually modified. DYBs only control the protection scheme for unprotected sectors that have their PPBs cleared (erased to "1"). By issuing the DYB Set or Clear command sequences, the DYBs are set (programmed to "0") or cleared (erased to "1"), thus placing each sector in the protected or unprotected state respectively. This feature allows software to easily protect sectors against inadvertent changes yet does not prevent the easy removal of protection when changes are needed. Notes 1. The DYBs can be set (programmed to "0") or cleared (erased to "1") as often as needed. When the parts are first shipped, the PPBs are cleared (erased to "1") and upon power up or reset, the DYBs can be set or cleared depending upon the ordering option chosen. 2. If the option to clear the DYBs after power up is chosen, (erased to "1"), then the sectorsmay be modified depending upon the PPB state of that sector (see Table 8). 3. The sectors would be in the protected state If the option to set the DYBs after power up is chosen (programmed to "0"). 4. It is possible to have sectors that are persistently locked with sectors that are left in the dynamic state. 5. The DYB Set or Clear commands for the dynamic sectors signify protected or unprotectedstate of the sectors respectively. However, if there is a need to change the status of the persistently locked sectors, a few more steps are required. First, the PPB Lock Bit must be cleared by either putting the device through a power-cycle, or hardware reset. The PPBs can then be changed to reflect the desired settings. Setting the PPB Lock Bit once again locks the PPBs, and the device operates normally again. 6. To achieve the best protection, it is recommended to execute the PPB Lock Bit Set command early in the boot code and protect the boot code by holding WP#/ACC = VIL. Note that the PPB and DYB bits have the same function when WP#/ACC = VHH as they do when ACC =VIH.
Persistent Protection Bit Lock Bit
The Persistent Protection Bit Lock Bit is a global volatile bit for all sectors. When set (programmed to "0"), it locks all PPBs and when cleared (programmed to "1"), allows the PPBs to be changed. There is only one PPB Lock Bit per device. Notes 1. No software command sequence unlocks this bit unless the device is in the password protection mode; only a hardware reset or a power-up clears this bit. 2. The PPB Lock Bit must be set (programmed to "0") only after all PPBs are configured to the desired settings.

the sector. In summary, if the PPB Lock Bit is locked (set to "0"), no changes to the PPBs are allowed. The PPB Lock Bit can only be unlocked (reset to "1") through a hardware reset or power cycle. See also Figure 8 for an overview of the Advanced Sector Protection feature.
Hardware Data Protection Methods
The device offers two main types of data protection at the sector level via hardware control: * When WP#/ACC is at VIL, the either the highest or lowest sector is locked (device specific). There are additional methods by which intended or accidental erasure of any sectors can be prevented via hardware means. The following subsections describes these methods:
WP#/ACC Method
The Write Protect feature provides a hardware method of protecting one outermost sector. This function is provided by the WP#/ACC pin and overrides the previously discussed Sector Protection/Unprotection method. If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the highest or lowest sector independently of whether the sector was protected or unprotected using the method described in Advanced Sector Protection/Unprotection on page 26. If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the boot sectors were last set to be protected or unprotected. That is, sector protection or unprotection for these sectors depends on whether they were last protected or unprotected. The WP#/ACC pin must be held stable during a command sequence execution. WP# has an internal pull-up; when unconnected, WP# is set at VIH. Note If WP#/ACC is at VIL when the device is in the standby mode, the maximum input load current is increased.
Low VCC Write Inhibit
When VCC is less than VLKO, the device does not accept any write cycles. This protects data during VCC power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets to reading array data. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the proper signals to the control inputs to prevent unintentional writes when VCC is greater than VLKO.
Write Pulse "Glitch Protection"
Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle.
Power-Up Write Inhibit
If WE# = CE# = RESET# = VIL and OE# = VIH during power up, the device does not accept commands on the rising edge of WE#. The internal state machine is automatically reset to the read mode on powerup.

Preliminary Power Conservation Modes
Standby Mode
EN29GL064
When the system is not reading or writing to the device, it can place the device in the standby mode. In this mode, current consumption is greatly reduced, and the outputs are placed in the high impedance state, independent of the OE# input. The device enters the CMOS standby mode when the CE# and RESET# inputs are both held at VCC 0.3 V. The device requires standard access time (tCE) for read access, before it is ready to read data. If the device is deselected during erasure or programming, the device draws active current until the operation is completed. ICC4 in "DC Characteristics" represents the standby current specification
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when addresses remain stable for tACC + 30 ns. The automatic sleep mode is independent of the CE#, WE#, and OE# control signals. Standard address access timings provide new data when addresses are changed. While in sleep mode, output data is latched and always available to the system.
Hardware RESET# Input Operation
The RESET# input provides a hardware method of resetting the device to reading array data. When RESET# is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates all outputs, and ignores all read/write commands for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is ready to accept another command sequence to ensure data integrity. When RESET# is held at VSS 0.3 V, the device draws ICC reset current (ICC5). If RESET# is held at VIL but not within VSS 0.3 V, the standby current is greater. RESET# may be tied to the system reset circuitry and thus, a system reset would also reset the Flash memory, enabling the system to read the boot-up firmware from the Flash memory.
Output Disable (OE#)
When the OE# input is at VIH, output from the device is disabled. The outputs are placed in the high impedance state. (With the exception of RY/BY#.)
Secured Silicon Sector Flash Memory Region
The Secured Silicon Sector provides an extra Flash memory region that enables permanent part identification through an Electronic Serial Number (ESN). The Secured Silicon Sector is 128 words in length and all Secured Silicon reads outside of the 128-word address range returns invalid data. The Secured Silicon Sector Indicator Bit, DQ7, (at Autoselect address 03h) is used to indicate whether or not the Secured Silicon Sector is locked when shipped from the factory. Please note the following general conditions: * On power-up, or following a hardware reset, the device reverts to sending commands to the normal address space. * Reads outside of sector SA0 return memory array data. * Sector SA0 is remapped from memory array to Secured Silicon Sector array. * Once the Secured Silicon Sector Entry Command is issued, the Secured Silicon Sector Exit command must be issued to exit Secured Silicon Sector Mode. * The Secured Silicon Sector is not accessible when the device is executing an Embedded Program or Embedded Erase algorithm. * The ACC function and unlock bypass modes are not available when the Secured Silicon Sector is enabled.

Factory Locked Secured Silicon Sector
The Factory Locked Secured Silicon Sector is always protected when shipped from the factory and has the Secured Silicon Sector Indicator Bit (DQ7) permanently set to a "1". This prevents cloning of a factory locked part and ensures the security of the ESN and customer code once the product is shipped to the field. These devices are available pre-programmed with one of the following: * A random, 8 Word secure ESN only within the Secured Silicon Sector (at addresses 000000H 000007H) * Both a random, secure ESN and customer code through the EON programming service. Customers may opt to have their code programmed through the EON programming services. EON programs the customer's code, with or without the random ESN. The devices are then shipped from the EON factory with the Secured Silicon Sector permanently locked. Contact your local representative for details on using EON programming services.
Customer Lockable Secured Silicon Sector
The Customer Lockable Secured Silicon Sector is always shipped unprotected (DQ7 set to "0"), allowing customers to utilize that sector in any manner they choose. If the security feature is not required, the Secured Silicon Sector can be treated as an additional Flash memory space. Please note the following: * Once the Secured Silicon Sector area is protected, the Secured Silicon Sector Indicator Bit is permanently set to "0." * The Secured Silicon Sector can be read any number of times, but can be programmed and locked only once. The Secured Silicon Sector lock must be used with caution as once locked, there is no procedure available for unlocking the Secured Silicon Sector area and none of the bits in the Secured Silicon Sector memory space can be modified in any way. * The accelerated programming (ACC) and unlock bypass functions are not available when the Secured Silicon Sector is enabled. * Once the Secured Silicon Sector is locked and verified, the system must write the Exit Secured Silicon Sector Region command sequence which return the device to the memory array at sector 0.
Secured Silicon Sector Entry/Exit Command Sequences
The system can access the Secured Silicon Sector region by issuing the three-cycle Enter Secured Silicon Sector command sequence. The device continues to access the Secured Silicon Sector region until the system issues the four-cycle Exit Secured Silicon Sector command sequence. The Secured Silicon Sector Entry Command allows the following commands to be executed * Read customer and factory Secured Silicon areas * Program the customer Secured Silicon Sector After the system has written the Enter Secured Silicon Sector command sequence, it may read the Secured Silicon Sector by using the addresses normally occupied by sector SA0 within the memory array. This mode of operation continues until the system issues the Exit Secured Silicon Sector command sequence, or until power is removed from the device.

COMMON FLASH INTERFACE (CFI)
EN29GL064
The common flash interface (CFI) specification outlines device and host systems software interrogation handshake, which allows specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and backward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility. This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address 55h in word mode (or address AAh in byte mode), any time the device is ready to read array data. The system can read CFI information at the addresses given in Tables 10~13.In word mode, the upper address bits (A7-MSB) must be all zeros. To terminate reading CFI data, the system must write the reset command. The system can also write the CFI query command when the device is in the autoselect mode. The device enters the CFI query mode and the system can read CFI data at the addresses given in Tables 10~13. The system must write the reset command to return the device to the autoselect mode.
