3. GENERAL DESCRIPTION
The F49L320UA/F49L320BA is a 32 Megabit, 3V only CMOS Flash memory device organized as 4M bytes of 8 bits or 2M words of 16bits. This device is packaged in standard 48-pin TSOP. It is designed to be programmed and erased both in system and can in standard EPROM programmers. With access times of 70 ns and 90 ns, the F49L320UA/F49L320BA allows the operation of high-speed microprocessors. The device has separate chip enable CE , write enable WE , and output enable OE controls. ESMT's memory devices reliably store memory data even after 100,000 program and erase cycles. The F49L320UA/F49L320BA is entirely pin and command set compatible with the JEDEC standard for 32 Megabit Flash memory devices. Commands are written to The F49L320UA/F49L320BA features a sector erase architecture. The device array is divided into eight 8KB, sixty-three 64KB for byte mode. The device memory array is divided into eight 4K word, sixty-three 32K word sectors for word mode. Sectors can be erased individually or in groups without affecting the data in other sectors. Multiple-sector erase and whole chip erase capabilities provide the flexibility to revise the data in the device. The sector protect/unprotect feature disables both program and erase operations in any combination of the sectors of the memory. This can be achieved in-system or via programming equipment. A low VCC detector inhibits write operations on loss of power. End of program or erase is detected by the Ready/Busy status pin, Data Polling of DQ7, or by the Toggle Bit I feature on DQ6. Once the program or erase cycle has been successfully completed, the device internally resets to the Read mode. The command register using standard microprocessor write timings.

Write Protect(WP#)
The write protect function provides a hardware method of protecting certain boot sectors without using VID. This function is one of two provided by WP#/ACC pin. If the system asserts VIL On the WP#/ACC pin, the device disables program and erase functions in the two outermost 8-Kbyte boot sectors independently of whether those sectors were protected or unprotected using the method. The two outermost 8-Kbyte boot sectors are the two sectors containing the lowest addresses in a bottom-boot configured device, or the two sectors containing the highest addresses in a top-boot configured device. If the system asserted VIH on the WP#/ACC pin, the device reverts to whether the two outermost 8-Kbyte boot sectors were last set to be protected or unprotected. That is, sector protection or unprotection for these two sectors depends on whether they were last protected or unprotected using the method.

Reset Mode : Hardware Reset
When the RESET pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tri-states all output pins, 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 later once the device is ready to accept another command sequence, to ensure the data integrity. The current is reduced for the duration of the RESET pulse. When RESET is held at VSS 0. 3V, the device draws CMOS standby current (ICC4). If RESET is held at VIL but not within VSS0. 3V, the standby current will be greater. The RESET pin may be tied to system reset circuitry. A system reset would thus reset the Flash memory, enabling the system to read the boot-up firm-ware from the Flash memory. If RESET is asserted during a program or erase embedded algorithm operation, the RY/ BY pin remains a "0" (busy) until the internal reset operation is complete, which requires a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/ BY to determine whether the reset operation is complete. If RESET is asserted when a program or erase operation is not executing, i.e. the RY/ BY is "1", the reset operation is completed within a time of tREADY (not during Embedded Algorithms). The system can read data after tRH when the RESET pin returns to VIH. Refer to the AC Characteristics tables 17 for Hardware Reset section & Figure 23 for the timing diagram.

See "Read Command" section for more information. Refer to the AC Read Operations table 14 for timing specifications and to Figure 5 for the timing diagram. ICC1 in the DC Characteristics table represents the active current specification for reading array data.
Write Mode
To write a command or command sequence (which includes programming data to the device and erasing sectors of memory), the system must drive WE and CE to VIL, and OE to VIH. The "Program Command" section has details on programming data to the device using standard command sequences. An erase operation can erase one sector, multiple sectors, or the entire device. Tables 1 and 2 indicate the address space that each sector occupies. A "sector address" consists of the address bits required to uniquely select a sector. The "Software Command Definitions" section has details on erasing a sector or t he entire chip, or suspending/resuming the erase operation. When the system writes the auto-select command sequence, the device enters the auto-select mode. The system can then read auto-select codes from the internal register (which is separate from the memory array) on DQ7-DQ0. Standard read cycle timings apply in this mode. Refer to the Auto-select Mode and Auto-select Command sections for more information. ICC2 in the DC Characteristics table represents the active current specification for the write mode. The "AC Characteristics" section contains timing specification tables and timing diagrams for write operations.
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when addresses remain unchanged for over 250ns. 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. ICC4 in the DC Characteristics table represents the automatic sleep mode current specification.
Read Mode
To read array data from the outputs, the system must drive the CE and OE pins to VIL. CE is the power control and selects the device. OE is the output control and gates array data to the output pins. WE should remain at VIH. The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data. Standard microprocessor's read cycles that assert valid addresses on the device address inputs produce valid data on the device data outputs. The device remains enabled for read access until the command register contents are altered.
Word / Byte Mode
This pin controls the I/O configuration of device. When BYTE = VIH or Vcc 0. 3V. The I/O configuration is x16 and t he pin of D15/A-1 is bi-direction Data I/O. However, BYTE = VIL or VSS 0.3V. The I/O configuration would be x8 and The pin of DQ15/A-1 only address input pin. You must define the function of this pin before enable this device.

Temporary Sector Unprotect Mode
This feature allows temporary unprotection of previously protected sector to change data in-system. This mode is activated by setting the RESET pin to VID(10V-10.5V). During this mode, all formerly protected sectors are un-protected and

can be programmed or erased by selecting the sector addresses. Once VID is removed from the RESET pin, all the previously protected sectors are protected again.

Output Disable Mode
With the OE is at a logic high level (VIH), outputs from the devices are disabled. This will cause the output pins in a high impedance state
F49L320UA/F49L320BA
Operation Temperature Condition -40C~85C
Figure 16 shows the algorithms and Figure 15 shows the timing diagram. This method uses standard microprocessor bus cycle timing. For sector unprotect, all unprotected sectors must first be protected prior to the first sector unprotect write cycle. The alternate method intended only for programming equipment requires VID on address pin A9, OE, and RESET .
Standby Mode
When CE and RESET are both held at VCC 0.3V, the device enter CMOS Standby mode. If CE and RESET are held at VIH, but not within the range of VCC 03V, t he device will still be in the standby mode, but the standby current will be larger. If the device is deselected during auto algorithm of erasure or programming, the device draws active current ICC2 until the operation is completed. ICC3 in the DC Characteristics table represents the standby current specification. The device requires standard access time (tCE) for read access from either of these standby modes, before it is ready to read data.
Auto-select Mode
The auto-select mode provides manufacturer and device identification and sector protection verification, through outputs on DQ7-DQ0. This mode is primarily intended for programming equipment to automatically match a device to be programmed with its corresponding programming algorithm. However, the auto-select codes can also be accessed in-system through the command register. When using programming equipment, this mode requires VID (10 V to 10.5 V) on address pin A9. While address pins A3, A2, A1, and A0 must be as shown in Table 4. To verify sector protection, all necessary pins have to be set as required in Table 4, the programming equipment may then read the corresponding identifier code on DQ7-DQ0. To access the auto-select codes in-system, the host system can issue the auto-select command via the command register, as shown in Table 5. This method does not require VID. See "Software Command Definitions" for details on using the auto-select mode.
Sector Protect / Un-protect Mode
The hardware sector protect feature disables both program and erase operations in any sector. The hardware sector unprotect feature re-enables both the program and erase operations in previously protected sectors. Sector protect/unprotect can be implemented via two methods. The primary method requires VID on the RESET pin only, and can be implemented either in-system or via programming equipment.
7.2 Software Command Definitions
Writing specific address and data commands or sequences into the command register initiates the device operations. Table 5 defines the valid register command sequences. Writing incorrect address and data values or writing them in the improper sequence resets the device to reading array data. All addresses are latched on the falling edge of WE or CE , whichever happens later. All data is latched on the rising edge of WE or CE , whichever happens first. Refer to the corresponding timing diagrams in the AC Characteristics section.

Reset Command
Writing the reset command to the device resets the device to reading array data. Address bits are all don't cares for this command. The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This resets the device to reading array data. Once erasure begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in a program command sequence before programming begins. This resets the device to reading array data (also applies to programming in Erase Suspend mode). Once programming begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in an auto-select command sequence. Once in the auto-select mode, the reset command must be written to return to reading array data (also applies to auto-select during Erase Suspend). If DQ5 goes high (see "DQ5: Exceeded Timing Limits" section) during a program or erase operation, writing the reset command returns the device to reading array data (also applies during Erase Suspend).
F49L320UA/F49L320BA
Operation Temperature Condition -40C~85C
Program Command
The program command sequence programs one byte into the device. Programming is a four-bus-cycle operation. The program command sequence is initiated by writing two unlock write cycles, followed by the program set-up command. The program address and data are written next, which in turn initiate the Embedded Program algorithm. The system is not required to provide further controls or timings. The device automatically provides internally generated program pulses and verifies the programmed cell margin. When the Embedded Program algorithm is complete, the device then returns to reading array data and addresses are no longer latched. The system can determine the status of the program operation by using DQ7, DQ6, or RY/ BY . See "Write Operation Status" section for more information on these status bits. Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a hardware reset immediately terminates the programming operation. The Program command sequence should be reinitiated once the device has reset to reading array data, to ensure data integrity. Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from a "0" back to a "1". Attempting to do so may halt the operation and set DQ5 to "1", or cause the Data Polling algorithm to indicate the operation was successful. However, a succeeding read will show that the data is still "0". Only erase operations can convert a "0" to a "1".
Read Command
The device is automatically set to reading array data after device power-up. No commands are required to retrieve data. The device is also ready to read array data after completing an Embedded Program or Embedded Erase algorithm. When the device accepts an Erase Suspend command, the device enters the Erase Suspend mode. The system can read array data using the standard read timings, except that if it reads an address within erase-suspended sectors, the device outputs status data. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See "Erase Suspend/Erase Resume Commands" for more information on this mode. The system must issue the reset command to re-enable the device for reading array data if DQ5 goes high, or while in the auto-select mode. See the "Reset Command" section. See also the "Read Mode" in the "Device Operations section for more information. Refer to Figure 5 for the timing diagram.
Chip Erase Command
Chip erase is a six-bus cycle operation. The chip erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase command, which in turn invokes the Embedded Erase algorithm. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire memory for an all zero data pattern prior to electrical erase. Any commands written to the chip during the Embedded Erase algorithm are ignored. Note that a hardware reset during the chip erase operation immediately terminates the operation. The Chip Erase command sequence should be reinitiated once the device has returned to reading array data, to ensure the data integrity.

The system can determine the status of the erase operation by using DQ7, DQ6, DQ2, or RY/ BY . See "Write Operation Status" section for more Information on these status bits.

See the Erase/Program Operations tables in "AC Characteristics" for parameters.

Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands are ignored. Note that a hardware reset during the sector erase operation immediately terminates the operation. The Sector Erase command sequence should be reinitiated once the device has returned to reading array data, to ensure the data integrity. When the Embedded Erase algorithm is complete, 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, DQ2, or RY/ BY . (Refer to "Write Operation Status" section for more information on these status bits.) Refer to the Erase/Program Operations tables in the "AC Characteristics" section for parameters.
Sector Erase Command
Sector erase is a six-bus cycle operation. The sector erase command sequence is initiated by writing two unlock 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 device does not require the system to preprogram the memory prior to erase. The Embedded Erase algorithm automatically programs and verifies the sector for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. After the command sequence is written, a sector erase time-out of 50 s begins. Driving the time-out period, additional sector addresses and sector erase commands may be written. Loading the sector erase buffer may be done in any sequence, and the number of sectors may be from one sector to all sectors. The time between these additional cycles must be less than 50 s, otherwise the last address and command might not be accepted, and erasure may begin. It is recommended that processor interrupts be disabled during this time to ensure all commands are accepted. The interrupts can be re-enabled after the last Sector Erase command is written. If the time between additional sector erase commands can be assumed to be less than 50 s, the system need not monitor DQ3. Any command other than Sector Erase or Erase Suspend during the time-out period resets the device to reading array data. The system must rewrite the command sequence and any additional sector addresses and commands. The system can monitor DQ3 to determine if the sector erase timer has timed out. (See the "DQ3: Sector Erase Timer" section.) The time-out begins from the rising edge of the final WE pulse in the command sequence.
Sector Erase Suspend/Resume Command
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 device " erase suspends" all sect or selected for erasure.). This command is valid only during the sector erase operation, including the 50 s time-out period during the sector erase command sequence. The Erase Suspend command is ignored if written during the chip erase operation or Embedded Program algorithm. Addresses are "don't -cares" when writing the Erase Suspend command as shown in Table 5. When the Erase Suspend command is written during a sector erase operation, the device requires a maximum of 20s to suspend the erase operation. However, when the Erase Suspend command is written during the sector erase time-out, the device immediately terminates the time-out period and suspends the erase operation. Reading at any address within erase-suspended sectors produces status data 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. See "Write Operation Status" section for more information on these status bits. After an erase-suspended program operation is complete, the system can once again read array data within non-suspended sectors. The system can determine the status of the program operation using the DQ7 or DQ6

status bits, just as in the standard program operation. See "Write Operation Status" f or more information. The system may also write the auto-select command sequence when the device is in the Erase Suspend mode. The device allows reading auto-select codes even at addresses within erasing sectors, since the codes are not stored in the memory array. When the device exits the auto-select mode, the device reverts to the Erase Suspend mode, and is ready for another valid operation. After an erase-suspended program operation is complete, the system can once again read array data within non-suspended sectors. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard program operation. See "Write Operation Status" f or more information. The system may also write the auto-select command sequence when the device is in the Erase Suspend mode. The device allows reading auto-select codes even at addresses within erasing sectors, since the codes are not stored in the memory array. When the device exits the auto-select mode, the device reverts to the Erase Suspend mode, and is ready for another valid operation. The system must write the Erase Resume command (address bits are "don't care" as shown in Table 5) to exit the erase suspend mode and continue the sector erase

operation. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the device has resumed erasing.
Auto-select Command
The auto-select command sequence allows the host system to access the manufacturer and devices codes, and determine whether or not a sector is protected. Table 6 shows the address and data requirements. This method is an alternative to that shown in Table 4, which is intended for PROM programmers and requires VID on address bit A9. The auto-select command sequence is initiated by writing two unlock cycles, followed by the auto-select command. The device then enters the auto-select mode, and the system may read at any address any number of times, without initiating another command sequence. The read cycles at address 04H, 08H, 0CH, and 00H retrieves the ESMT manufacturer ID. A read cycle at address 01H retrieves the device ID. A read cycle containing a sector address(SA) and the address 02H returns 01H if that sector is protected, or 00H if it is unprotected. Refer to Tables 1 and 2 for valid sector addresses. The system must write the reset command to exit the auto-select mode and return to reading array data.
7.3 Write Operation Status
The device provides several bits to determine the status of a write operation: RY/ BY , DQ7, DQ6, DQ5, DQ3, DQ2, and. Table 7 and the following subsections describe the functions of these bits. RY/ BY , DQ7, and DQ6 each offer a method for determining whether a program or erase operation is complete or in progress.

RY/ BY : Ready/Busy
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. If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.) If the output is high (Ready), the device is ready to read array data (including during the Erase Suspend mode), or is in the standby mode. Table 7 shows the outputs for RY/ BY .

Output Enable ( OE) is asserted low. Refer to Figure 21, Data Polling Timings (During Embedded Algorithms), Figure 19 shows the Data Polling algorithm.
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 cause DQ6 to toggle. The system may use either OE or CE to control the read cycles. When the operation is complete, DQ6 stops toggling. When 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-suspended. When the device is actively erasing (i.e. 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 2s 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. Table 7 shows the outputs for Toggle Bit I on DQ6. Figure 20 shows the toggle bit algorithm. Figure 22 shows the toggle bit timing diagrams. Figure 25 shows the differences between DQ2 and DQ6 in graphical form. Refer to the subsection on DQ2: Toggle Bit II.
DQ7: Data Polling
The DQ7 indicates to the host system whether an Embedded Algorithm is in progress or completed, or whether the device is in Erase Suspend mode. The Data Polling is valid after the rising edge of the final WE pulse in the program or erase command sequence. 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 true data on 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 for approximately 1 s, then the device returns to reading array data. 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 Polling on DQ7 is active for approximately 100 s, then the device 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. When the system detects DQ7 has changed from the complement to true data, it can read valid data at DQ7~ DQ0 on the following read cycles. This is because DQ7 may change asynchronously with DQ0-DQ6 while
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 erase-suspended. Toggle Bit II is valid after the rising edge of the final or CE , whichever happens first, in the command sequence.

ESMT
DQ2 toggles when the system reads at addresses within those sectors that have been selected for erasure. (The system may use either OE or CE to control the read cycles.) 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 whether is in erase-suspended, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sector and mode information. Refer to Table 7 to compare outputs for DQ2 and DQ6. Figure 20 shows the toggle bit algorithm in flowchart form. See also the DQ6: Toggle Bit I subsection. Figure 22 shows the toggle bit timing diagram. Figure 25 shows the differences between DQ2 and DQ6 in graphical form.

exceeded the specified limits(internal pulse count). Under these conditions DQ5 will produce a "1". This time-out condition indicates that the program or erase cycle was not successfully completed. Data Polling and Toggle Bit are the only operating functions of the device under this condition. If this time-out condition occurs during sector erase operation, it specifies that a particular sector is bad and it may not be reused. However, other sectors are still functional and may be used for the program or erase operation. The device must be reset to use other sectors. Write the Reset command sequence to the device, and then execute program or erase command sequence. This allows the system to continue to use the other active sectors in the device. If this time-out condition occurs during the chip erase operation, it specifies that the entire chip is bad or combination of sectors are bad. If this time-out condition occurs during the programming operation, it specifies that the sector containing that byte is bad and this sector may not be reused, however other sectors are still functional and can be reused. The time-out condition will not appear if a user tries to program a non blank location without erasing. Please note that this is not a device failure condition since the device was incorrectly used.
Reading Toggle Bits DQ6/ DQ2
Refer to Figure 20 for the following discussion. 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 erase 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 should note whether the value of DQ5 is high (see the section on DQ5). 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 erase operation. If it is still toggling, the device did not completed 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 earlier. 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.
DQ3:Sector Erase Timer
After writing a sector erase command sequence, the system may read DQ3 to determine whether or not an erase operation has begun. (The sector erase timer does not apply to the chip erase command.) If additional sectors are selected for erasure, the entire timeout also applies after each additional sector erase command. When the time-out is complete, DQ3 switches from " 0" to " 1." If the time between additional sector erase commands from the system can be assumed to be less than 50 s, the system need not monitor DQ3. When the sector erase command sequence is written, the system should read the status on DQ7 (Data Polling) or DQ6 (Toggle Bit I) to ensure the device has accepted the command sequence, and then read DQ3. If DQ3 is " 1", the internally controlled erase cycle has begun; all further commands (except Erase Suspend) are ignored until the erase operation is complete. If DQ3 is " 0", the device will accept additional sector erase commands. To ensure the command has been accepted, the system software should check the status of DQ3 prior to and following each subsequent sector erase command. If DQ3 is high on the second status check, the last command might not have been accepted. Table 7 shows the outputs for DQ3.

Customer Lockable : Secured Silicon Sector NOT Programmed or Protected at the Factory
The customer lockable version allows the Secured Silicon Sector to be programmed once, and then permanently locked after it ships. Note that the accelerated programming (ACC) is not available when programming the Secured Silicon Sector. The Secured Silicon Sector area can be protected using the following procedures: Write the three-cycle Enter Secured silicon Region command sequence, and then follow the in-system sector protect algorithm as shown in Figure 16. of page41, except that RESET# may be either VIH or VID. This allows in system protection of the Secured Silicon Sector without raising any device pin to a high voltage. Note that this method is only applicable to the Secured silicon Sector. To verify the protect/unprotect status of the Secured Silicon Sector, follow the algorithm shown in below table. Once the Secured Silicon Sector protection must be used with caution since, once protected, there is no procedure available for unprotecting the Secured silicon Sector area, and none of the bits in the Secured Silicon Sector memory space can be modified in any way.

Factory Locked : Secured Silicon Sector Programmed and Protected at the Factory
The Secured Silicon Sector feature provides a 256 -byte Flash memory region that enables permanent part identification through an Electronic Serial Number (ESN). The Secured Silicon Sector uses a Secured Silicon Sector Indicator Bit (DQ7) to indicate whether or not the Secured Silicon Sector is locked when shipped from the factory. Factory Locked version the Bit( DQ7) set to 1, Customer Lockable version the Bit (DQ7) set to 0. In a factory locked device, the Secured Silicon Sector cannot be modified in any way. The device is available pre-programmed with one of the following: 1. A random, secure ESN only. 2. Customer code through the Express Flash service. 3. Both a random, secure ESN and customer code through the Express Flash device. In device that have an ESN, a Bottom Boot device has the 16-byte (8-word) ESN in sector 0 at address 00000H-0000FH in byte mode(or 00000H~00007H in word mode).In the Top Boot device, the ECN is in sector 70 at addresses 3FFF00h-3FFF0Fh in byte mode ( or 1FFF80h-1FFF87h in word mode). In the uniform device, the ESN is in sector 63 at addresses 3FFF00h-3FFF0Fh in byte mode (or 1FFF80h1FFF87h in word mode). Customers may opt to have their code programmed by ESMT through the Express-Flash service. ESMT programs the customer's code, with or without the random ESN. The devices are then shipped from the ESMT factory with the Secured Silicon Sector locked. Note: 1. After entering Secured Silicon Sector mode, user can program Secured Silicon Sector (means to write ESN code) and do Secured Silicon Sector protection once when device is customer lockable version. 2. Enter Secured Silicon Sector mode, the under functions are not allowed except for CFI. a. Sector Erase/Erase Suspend/Resume. b. Chip Erase. 3. Secured Silicon Sector mode doesn't have "Erase" and "Unprotect" function.

7.4 More Device Operations
Hardware Data Protection
The command sequence requirement of unlock cycles for programming or erasing provides data protection against inadvertent writes. In addition, the following hardware data protection measures prevent accidental erasure or programming, which might otherwise be caused by spurious system level signals during VCC power-up and power-down transitions, or from system noise.
Logical Inhibit
Write cycles are inhibited by holding any one of OE = VIL, CE = VIH or WE = VIH. To initiate a write cycle, CE and WE must be a logical zero while OE is a logical one.
Power Supply Decoupling
In order to reduce power switching effect, each device should have a 0.1uF ceramic capacitor connected between its VCC and GND.
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. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the proper signals to the control pins to prevent unintentional writes when VCC is greater than VLKO.
Power-Up Sequence
The device powers up in the Read Mode. In addition, the memory contents may only be altered after successful completion of the predefined command sequences.
Power-Up Write Inhibit
If WE = CE = 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 reading array data on power-up.
Write Pulse "Glitch" Protection
Noise pulses of less than 5 ns (typical) on CE or WE do not initiate a write cycle.

Operation Temperature Condition -40C~85C
The Common Flash Interface (CFI) specification outlines device and host system 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 array data. The system can read CFI information at the address given in Tables 8-10 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 8-10. The system must write the reset command to return the device to the autoselect mode.
