In a command cycle, all address are latched at the later falling edge of WE#, and all data are latched at the earlier rising edge of WE#. Figure 1 illustrates the AC timing waveform of a write command, and Table 3 defines all the valid command sets of the device. System is not allowed to write invalid commands not defined in this datasheet. Writing an invalid command will bring the device to an undefined state. REQUIREMENTS FOR READING ARRAY DATA Read array action is to read the data stored in the array. While the memory device is in powered up or has been reset, it will automatically enter the status of read array. If the microprocessor wants to read the data stored in array, it has to drive CE# (device enable control pin) and OE# (Output control pin) as Vil, and input the address of the data to be read into address pin at the same time. After a period of read cycle (Tce or Taa), the data being read out will be displayed on output pin for microprocessor to access. If CE# or OE# is Vih, the output will be in tri-state, and there will be no data displayed on output pin at all. After the memory device completes embedded operation (automatic Erase or Program), it will automatically return to the status of read array, and the device can read the data in any address in the array. In the process of erasing, if the device receives the Erase suspend command, erase operation will be stopped temporarily after a period of time no more than Tready1 and the device will return to the status of read array. At this time, the device can read the data stored in any address except the sector being erased in the array. In the status of erase suspend, if user wants to read the data in the sectors being erased, the device will output status data onto the output. Similarly, if program command is issued after erase suspend, after program operation is completed, system can still read array data in any address except the sectors to be erased The device needs to issue reset command to enable read array operation again in order to arbitrarily read the data in the array in the following two situations: 1. In program or erase operation, the programming or erasing failure causes Q5 to go high. 2. The device is in auto select mode or CFI mode. In the two situations above, if reset command is not issued, the device is not in read array mode and system must issue reset command before reading array data. P/N:PM1300 REV. 2.6, DEC. 22, 2011 19 MX29LV400C T/B MX29LV800C T/B MX29LV160C T/B RESET# OPERATION Driving RESET# pin low for a period more than Trp will reset the device back to read mode. If the device is in program or erase operation, the reset operation will take at most a period of Tready1 for the device to return to read array mode. Before the device returns to read array mode, the RY/BY# pin remains low (busy status). When RESET# pin is held at GND±0.3V, the device consumes standby current(Isb).However, device draws larger current if RESET# pin is held at Vil but not within GND±0.3V. It is recommended that the system to tie its reset signal to RESET# pin of flash memory, so that the flash memory will be reset during system reset and allows system to read boot code from flash memory. SECTOR PROTECT OPERATION When a sector is protected, program or erase operation will be disabled on that protected sector. MX29LV400C/ MX29LV800C/MX29LV160C T/B provides two methods for sector protection. Once the sector is protected, the sector remains protected until next chip unprotect, or is temporarily unprotected by asserting RESET# pin at Vhv. Refer to temporary sector unprotect operation for further details. The first method is by applying Vhv on RESET# pin. Refer to Figure 12 for timing diagram and Figure 13 for the algorithm for this method. The other method is asserting Vhv on A9 and OE# pins, with A6 and CE# at Vil. The protection operation begins at the falling edge of WE# and terminates at the rising edge. Contact Macronix for details. CHIP UNPROTECT OPERATION MX29LV400C/MX29LV800C/MX29LV160C T/B provides two methods for chip unprotect. The chip unprotect operation unprotects all sectors within the device. It is recommended to protect all sectors before activating chip unprotect mode. All sectors are unprotected when shipped from the factory. The first method is by applying Vhv on RESET# pin. Refer to Figure 12 for timing diagram and Figure 13 for algorithm of the operation. The other method is asserting Vhv on A9 and OE# pins, with A6 at Vih and CE# at Vil (see Table 2). The unprotect operation begins at the falling edge of WE# and terminates at the rising edge. Contact Macronix for details. TEMPORARY SECTOR UNPROTECT OPERATION System can apply RESET# pin at Vhv to place the device in temporary unprotect mode. In this mode, previously protected sectors can be programmed or erased just as it is unprotected. The devices returns to normal operation once Vhv is removed from RESET# pin and previously protected sectors are again protected. P/N:PM1300 REV. 2.6, DEC. 22, 2011 20 MX29LV400C T/B MX29LV800C T/B MX29LV160C T/B AUTOMATIC SELECT OPERATION When the device is in Read array mode, erase-suspended read array mode or CFI mode, user can issue read silicon ID command to enter read silicon ID mode. After entering read silicon ID mode, user can query several silicon IDs continuously and does not need to issue read silicon ID mode again. When A0 is Low, device will output Macronix Manufacture ID C2. When A0 is high, device will output Device ID. In read silicon ID mode, issuing reset command will reset device back to read array mode or erase-suspended read array mode. Another way to enter read silicon ID is to apply high voltage on A9 pin with CE#, OE#, A6 and A1 at Vil. While the high voltage of A9 pin is discharged, device will automatically leave read silicon ID mode and go back to read array mode or erase-suspended read array mode. When A0 is Low, device will output Macronix Manufacture ID C2. When A0 is high, device will output Device ID. VERIFY SECTOR PROTECT STATUS OPERATION MX29LV400C/MX29LV800C/MX29LV160C T/B provides hardware sector protection against Program and Erase operation for protected sectors. The sector protect status can be read through Sector Protect Verify command. This method requires Vhv on A9 pin, Vih on WE# and A1 pins, Vil on CE#, OE#, A6 and A0 pins, and sector address on A12 to Am pins. If the read out data is 01H, the designated sector is protected. Oppositely, if the read out data is 00H, the designated sector is not protected. DATA PROTECTION To avoid accidental erasure or programming of the device, the device is automatically reset to read array mode during power up. Besides, only after successful completion of the specified command sets will the device begin its erase or program operation. Other features to protect the data from accidental alternation are described as followed. LOW VCC WRITE INHIBIT The device refuses to accept any write command when Vcc is less than 1.4V. This prevents data from spuriously altered. The device automatically resets itself when Vcc is lower than 1.4V and write cycles are ignored until Vcc is greater than 1.4V. System must provide proper signals on control pins after Vcc is larger than 1.4V to avoid unintentional program or erase operation WRITE PULSE "GLITCH" PROTECTION CE#, WE#, OE# pulses shorter than 5ns are treated as glitches and will not be regarded as an effective write cycle. LOGICAL INHIBIT A valid write cycle requires both CE# and WE# at Vil with OE# at Vih. Write cycle is ignored when either CE# at Vih, WE# a Vih, or OE# at Vil.

Furthermore, program or erase operation will begin only after successful completion of specified command sequences. POWER-UP WRITE INHIBIT When WE#, CE# is held at Vil and OE# is held at Vih during power up, the device ignores the first command on the rising edge of WE#. POWER SUPPLY DECOUPLING A 0.1uF capacitor should be connected between the Vcc and GND to reduce the noise effect.

While the device is in read silicon ID mode, sector protect verify or CFI mode, user must issue reset command to reset device back to read array mode. When the device is in the progress of programming (not program fail) or erasing (not erase fail), device will ignore reset command. AUTOMATIC SELECT COMMAND SEQUENCE Automatic Select mode is used to access the manufacturer ID, device ID and to verify whether or not a sector is protected. The automatic select mode has four command cycles. The first two are unlock cycles, and followed by a specific command. The fourth cycle is a normal read cycle, and user can read at any address any number of times without entering another command sequence. The reset command is necessary to exit the Automatic Select mode and back to read array. The following table shows the identification code with corresponding address. Read Silicon ID Manufacturer ID Device ID Sector Protect Verify Word Byte Word Byte Word Byte Address X00 X00 X01 X02 (Sector address) X 02 (Sector address) X 04 Data (Hex) 00C2 C2 ID ID 00/01 00/01 Representation Top/Bottom Boot Sector Top/Bottom Boot Sector Unprotected/protected Unprotected/protected There is an alternative method to that shown in Table 2, which is intended for EPROM programmers and requires Vhv on address bit A9. P/N:PM1300 REV. 2.6, DEC. 22, 2011 24 MX29LV400C T/B MX29LV800C T/B MX29LV160C T/B AUTOMATIC PROGRAMMING The MX29LV400C/MX29LV800C/MX29LV160C T/B can provide the user program function by the form of ByteMode or Word-Mode. As long as the users enter the right cycle defined in the Table.3 (including 2 unlock cycles and A0H), any data user inputs will automatically be programmed into the array. Once the program function is executed, the internal write state controller will automatically execute the algorithms and timings necessary for program and verification, which includes generating suitable program pulse, verifying whether the threshold voltage of the programmed cell is high enough and repeating the program pulse if any of the cells does not pass verification. Meanwhile, the internal control will prohibit the programming to cells that pass verification while the other cells fail in verification in order to avoid over-programming. With the internal write state controller, the device requires the user to write the program command and data only. Programming will only change the bit status from "1" to "0". That is to say, it is impossible to convert the bit status from "0" to "1" by programming. Meanwhile, the internal write verification only detects the errors of the "1" that is not successfully programmed to "0". Any command written to the device during programming will be ignored except hardware reset, which will terminate the program operation after a period of time no more than Tready1. When the embedded program algorithm is complete or the program operation is terminated by hardware reset, the device will return to the reading array data mode. The typical chip program time at room temperature of the MX29LV400C/MX29LV800C/MX29LV160C T/B is less than 36 seconds. When the embedded program operation is on going, user can confirm if the embedded operation is finished or not by the following methods: Status In progress*1 Finished Exceed time limit Q7 Q7# Q7 Q7# Q6 Toggling Stop toggling Toggling Q5 0 0 1 RY/BY#*2 0 1 0 *1: The status "in progress" means both program mode and erase-suspended program mode. *2: RY/BY# is an open drain output pin and should be weakly connected to VDD through a pull-up resistor. *3: When an attempt is made to program a protected sector, Q7 will output its complement data or Q6 continues to toggle for about 1us or less and the device returns to read array state without programing the data in the protected sector.

It needs 6 cycles to write the action in, and the first two cycles are "unlock" cycles, the third one is a configuration cycle, the fourth and fifth are also "unlock" cycles, and the sixth cycle is the chip erase operation. During chip erasing, all the commands will not be accepted except hardware reset or the working voltage is too low that chip erase will be interrupted. After Chip Erase, the chip will return to the state of Read Array. When the embedded chip erase operation is on going, user can confirm if the embedded operation is finished or not by the following methods: Status In progress Finished Exceed time limit Q7 0 1 0 Q6 Toggling Stop toggling Toggling Q5 0 0 1 Q2 Toggling 1 Toggling RY/BY# 0 1 0 SECTOR ERASE Sector Erase is to erase all the data in a sector with "1" and "0" as all "1". It requires six command cycles to issue. The first two cycles are "unlock cycles", the third one is a configuration cycle, the fourth and fifth are also "unlock cycles" and the sixth cycle is the sector erase command. After the sector erase command sequence is issued, there is a time-out period of 50us counted internally. During the time-out period, additional sector address and sector erase command can be written multiply. Once user enters another sector erase command, the time-out period of 50us is recounted. If user enters any command other than sector eras or erase suspend during time-out period, the erase command would be aborted and the device is reset to read array condition. The number of sectors could be from one sector to all sectors. After time-out period passing by, additional erase command is not accepted and erase embedded operation begins. During sector erasing, all commands will not be accepted except hardware reset and erase suspend and user can check the status as chip erase. When the embedded erase operation is on going, user can confirm if the embedded operation is finished or not by the following methods: Status Time-out period In progress Finished Exceed time limit Q7 0 0 1 0 Q6 Toggling Toggling Stop toggling Toggling Q5 0 0 0 1 Q3 0 1 1 1 Q2 Toggling Toggling 1 Toggling RY/BY#*2 0 0 1 0 *1: The status Q3 is the time-out period indicator. When Q3=0, the device is in time-out period and is acceptible to another sector address to be erased. When Q3=1, the device is in erase operation and only erase suspend is valid. *2: RY/BY# is open drain output pin and should be weakly connected to VDD through a pull-up resistor. *3: When an attempt is made to erase a protected sector, Q7 will output its complement data or Q6 continues to toggle for 100us or less and the device returned to read array status without erasing the data in the protected sector.

If user issue erase suspend command in the time-out period of sector erasure, device time-out period will be over immediately and the device will go back to erase-suspended read array mode. If user issue erase suspend command during the sector erase is being operated, device will suspend the ongoing erase operation, and after the Tready1 (
