7 p/n:pm1200 rev. 2.1, jun. 30, 2009 mx29f400c t/b requirements for reading array data read array action is to read the data stored in the array out. 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 re - turn 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 after a period of time no more than treadyand 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 ar - ray 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. 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. write commands/command sequences to write a command to the device, system must drive we# and ce# to vil, and oe# to vih. in a command cycle, all address are latched at the later falling edge of ce# and we#, and all data are latched at the earlier rising edge of ce# and we#. figure 1 illustrates the ac timing waveform of a write command, and table 3 defnes all the valid command sets of the device. system is not allowed to write invalid commands not defned in this datasheet. writing an invalid command will bring the device to an undefned state. 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 tready 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 larg - er 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 fash memory, so that the fash memo - ry will be reset during system reset and allows system to read boot code from fash memory.
8 p/n:pm1200 rev. 2.1, jun. 30, 2009 mx29f400c t/b sector protect operation when a sector is protected, program or erase operation will be disabled on these sectors. mx29f400c t/b pro - vides one method 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. this method is by applying vhv on reset# pin. refer to figure 12 for timing diagram and figure 13 for the al - gorithm for this method. chip unprotect operation mx29f400c t/b provides one method 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 sector are unprotected when shipped from the factory. this method is by applying vhv on reset# pin. refer to figure 12 for timing diagram and figure 13 for algo - rithm of the operation. 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 opera - tion once vhv is removed from reset# pin and previously protected sectors are again protected. automatic select operation when the device is in read array mode or erase-suspended read array 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 ma - cronix 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# 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.
9 p/n:pm1200 rev. 2.1, jun. 30, 2009 mx29f400c t/b verify sector protect status operation mx29f400c t/b provides hardware sector protection against program and erase operation for protected sec - tors. the sector protect status can be read through sector protect verify command. this method requires v hv on a9 pin, vih on we# and a1 pins, vil on ce#, oe#, a6 and a0 pins, and sector address on a12 to a17 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 still not being 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 specifed command sets will the device begin its erase or program operation. other features to protect the data from accidental alternation are described as followed. 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. power-up sequence upon power up, mx29f400c t/b is placed in read array mode. furthermore, program or erase operation will be - gin only after successful completion of specifed 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 frst 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.

11 p/n:pm1200 rev. 2.1, jun. 30, 2009 mx29f400c t/b reset in the following situations, executing reset command will reset device back to read array mode: ? among erase command sequence (before the full command set is completed) ? sector erase time-out period ? erase fail (while q5 is high) ? among program command sequence (before the full command set is completed, erase-suspended program included) ? program fail (while q5 is high, and erase-suspended program fail is included) ? read silicon id mode ? sector protect verify while device is at the status of program fail or erase fail (q5 is high), user must issue reset command to reset device back to read array mode. while the device is in read silicon id mode or sector protect verify 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 ig - nore 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 frst two are unlock cycles, and followed by a specifc 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 se - lect mode and back to read array. the following table shows the identifcation code with corresponding address. address data (hex) representation manufacturer id word x00 00c2 byte x00 c2 device id word x01 2223/22ab top/bottom boot sector byte x02 23/ab top/bottom boot sector sector protect verify word (sector address) x 02 00/01 unprotected/protected byte (sector address) x 04 00/01 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.
12 p/n:pm1200 rev. 2.1, jun. 30, 2009 mx29f400c t/b automatic programming the mx29f400c t/b can provide the user program function by the form of byte-mode or word-mode. as long as the users enter the right cycle defned 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 algo - rithms and timings necessary for program and verifcation, 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 verifcation. meanwhile, the internal control will prohibit the programming to cells that pass verifcation while the other cells fail in verifcation in order to avoid over-programming. 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 verifcation 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 termi - nate the program operation after a period of time no more than tready. 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. with the internal write state controller, the device requires the user to write the program command and data only. the typical chip program time at room temperature of the mx29f400c t/b is 3 seconds. (word-mode) when the embedded program operation is on going, user can confrm if the embedded operation is fnished or not by the following methods: status q7 q6 q5 ry/by#*2 in progress*1 q7# toggling 0 0 finished q7 stop toggling 0 1 exceed time limit q7# toggling 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 and the device returns to read array state without programing the data in the protected sector.
13 p/n:pm1200 rev. 2.1, jun. 30, 2009 mx29f400c t/b 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 is - sue. the frst two cycles are "unlock cycles", the third one is a confguration cycle, the fourth and ffth 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 ad - dress 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 erase or erase suspend dur - ing 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 com - mand 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 chip erase operation is on going, user can confrm if the embedded operation is fnished or not by the following methods: status q7 q6 q5 q2 ry/by# in progress 0 toggling 0 toggling 0 finished 1 stop toggling 0 1 1 exceed time limit 0 toggling 1 toggling 0 when the embedded erase operation is on going, user can confrm if the embedded operation is fnished or not by the following methods: status q7 q6 q5 q3 q2 ry/by#*2 time-out period 0 toggling 0 0 toggling 0 in progress 0 toggling 0 1 toggling 0 finished 1 stop toggling 0 1 1 1 exceed time limit 0 toggling 1 1 toggling 0 chip erase chip erase is to erase all the data with "1" and "0" as all "1". it needs 6 cycles to write the action in, and the frst two cycles are "unlock" cycles, the third one is a confguration cycle, the fourth and ffth 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 rests 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. *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 and the device returned to read array status without erasing the data in the protected sector.
