diagram on page 9 illustrates a simplifed architecture of this device. each block in the block diagram represents one or more circuit modules in the real chip used to access, erase, program, and read the memory array. the "control input logic" block receives input pins ce#, oe#, we#, reset#, byte#, and wp#/acc. it creates internal timing control signals according to the input pins and outputs to the "address latch and buffer" to latch the external address pins a0-am. the internal addresses are output from this block to the main array and decoders composed of "x-decoder", "y-decoder", "y-pass gate", and "flash array". the x-decoder decodes the word-lines of the fash array, while the y-decoder decodes the bit-lines of the fash array. the bit lines are electrically connected to the "sense amplifier" and "pgm data hv" selectively through the y-pass gates. sense amplifiers are used to read out the contents of the fash memory, while the "pgm data hv" block is used to selectively deliver high power to bit-lines during programming. the "i/o buffer" controls the input and output on the q0-q15/a-1 pads. during read operation, the i/o buffer re - ceives data from sense amplifiers and drives the output pads accordingly. in the last cycle of program com - mand, the i/o buffer transmits the data on q0-q15/a-1 to "program data latch", which controls the high power drivers in "pgm data hv" to selectively program the bits in a word or byte according to the user input pattern. the "program/erase high voltage" block comprises the circuits to generate and deliver the necessary high voltage to the x-decoder, flash array, and "pgm data hv" blocks. the logic control module com - prises of the "write state machine, wsm", "state register", "command data decoder", and "command data latch". when the user issues a command by toggling we#, the command on q0-q15/a-1 is latched in the command data latch and is decoded by the command data decoder. the state register receives the command and records the current state of the device. the wsm implements the in - ternal algorithms for program or erase according to the current command state by controlling each block in the block diagram. array architecture the main fash memory array can be organized as byte mode (x8) or word mode (x16). the details of the ad - dress ranges and the corresponding sector addresses are shown in

output pins. page read this device is able to conduct mxic maskrom compatible high performance page read. page size is 16 bytes or 8 words. the higher address amax ~ a3 select the certain page, while a2~a0 for word mode, a2~a-1 for byte mode select the particular word or byte in a page. the page access time is taa or tce, following by tpa for the rest of the page read time. when ce# toggles, access time is taa or tce. page mode can be turned on by keeping "page-read address" constant and changing the "intra-read page" addresses. write operation to perform a write operation, the system provides the desired address on the address pins, enables the chip by asserting ce# low, and disables the data (i/o) pins by holding oe# high. the system then places data to be written on the data (i/o) pins and pulses we# low. the device captures the address information on the falling edge of we# and the data on the rising edge of we#. to see an example, please refer to the timing diagram in figure 4. the system is not allowed to write invalid commands (commands not defned in this datasheet) to the device. writing an invalid command may put the device in an undefned state. device reset driving the reset# pin low for a period of trp or more will return the device to read mode. if the device is in the middle of a program or erase operation, the reset operation will take at most a period of tready1 before the device returns to read mode. until the device does returns to read mode, the ry/by# pin will remain low (busy status). when the reset# pin is held at gnd0.3v, the device only consumes standby (isbr) current. however, the de - vice draws larger current if the reset# pin is held at a voltage greater than gnd+0.3v and less than or equal to vil. it is recommended to tie the system reset signal to the reset# pin of the fash memory. this allows the device to be reset with the system and puts it in a state where the system can immediately begin reading boot code from it. standby mode the device enters standby mode whenever the reset# and ce# pins are both held high except in the embed - ded mode. while in this mode, we# and oe# will be ignored, all data output pins will be in a high impedance state, and the device will draw minimal (isb) current. p/n:pm1509 rev. 1.5, oct. 21, 2015 mx29gl320e t/b mx29gl320e h/l 20 functional operation description (cont'd) output disable while in active mode (reset# high and ce# low), the oe# pin controls the state of the output pins. if oe# is held high, all data (i/o) pins will remain tri-stated. if held low, the byte or word data (i/o) pins will drive data. byte/word selection the byte# input pin is used to select the organization of the array data and how the data is input/output on the data (i/o) pins. if the byte# pin is held high, word mode will be selected and all 16 data lines (q0 to q15) will be active. if byte# is forced low, byte mode will be active and only data lines q0 to q7 will be active. data lines q8 to q14 will remain in a high impedance state and q15 becomes the a-1 address input pin. hardware write protect by driving the wp#/acc pin low. the top or bottom two sectors (for mx29gl320e t/b) and the highest or low - est sector (for mx29gl320e h/l) was protected from all erase/program operations. if wp#/acc is held high (vih to vcc), these sectors revert to their previously protected/unprotected status. accelerated programming operation by applying high voltage (vhv) to the wp#/acc pin, the device will enter the accelerated programming mode. this mode permits the system to skip the normal command unlock sequences and program byte/word locations directly. during accelerated programming, the current drawn from the wp#/acc pin is no more than icp1. write buffer programming operation programs 32bytes/16words in a programming operation. to trigger the write buffer programming, start by the frst two unlock cycles, then third cycle writes the write buffer load command at the destined programming sec - tor address. the forth cycle writes the "word locations subtract one" number. following above operations, system starts to write the mingling of address and data. after the programming of the frst address or data, the "write-buffer-page" is selected. the following data should be within the above men - tioned page. the "write-buffer-page" is selected by choosing address amax-a4. "write-buffer-page" address has to be the same for all address/ data write into the write buffer. if not, operation will abort. to program the content of the write buffer page this command must be followed by a write to buffer program con- frm command. the operation of write-buffer can be suspended or resumed by the standard commands, once the write buffer programming operation is fnished, itll return to normal read mode. p/n:pm1509 rev. 1.5, oct. 21, 2015 mx29gl320e t/b mx29gl320e h/l 21 functional operation description (cont'd) write buffer programming operation (cont'd) abort will be

the "write buf fer data loading" operation. ? w riting not "confrm command" after the assigned number of "data load" cycles. at write buffer abort mode, the status register will be q1=1, q7=data#

sequence. however the cfi functions, autoselect, secured silicon sector are not functional when program operation is in progress. multiple write buffer programming opera - tions on the same write buffer address range without intervening erases is available. any bit in a write buffer ad - dress range cant be programmed from 0 back to 1. sector protect operation the device provides user programmable protection operations for selected sectors. please refer to table 1 which show all sector assignments. during the protection operation, the sector address of any sector may be used to specify the sector being pro - tected. automatic select bus operations the following fve bus operations require a9 to be raised to vhv. please see automatic select command sequence in the command operations section for details of equivalent command operations that do not require the use of vhv. sector lock status verification to determine the protected state of any sector using bus operations, the system performs a read operation with a9 raised to vhv, the sector address applied to address pins a20 to a12, address pins a6, a3, a2 & a0 held low, and address pin a1 held high. if data bit q0 is low, the sector is not protected, and if q0 is high, the sector is protected. p/n:pm1509 rev. 1.5, oct. 21, 2015 mx29gl320e t/b mx29gl320e h/l 22 functional operation description (cont'd) read

automatically reset to read mode during power up. additionally, the following design features protect the device from unintended data corruption. command completion only after the successful completion of the specifed command sets will the device begin its erase or program operation. the failure in observing valid command sets will result in the memory returning to read mode. low vcc write inhibit the device refuses to accept any write command when vcc is less than vlko. this prevents data from spuriously being altered during power-up, power-down, or temporary power interruptions. the device automatically resets itself when vcc is lower than vlko and write cycles are ignored until vcc is greater than vlko. the system must provide proper signals on control pins after vcc rises above vlko to avoid unintentional program or erase operations. 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# at vih, or oe# at vil. p/n:pm1509 rev. 1.5, oct.

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. p/n:pm1509 rev. 1.5, oct. 21, 2015 mx29gl320e t/b mx29gl320e h/l 24 command operations reading the memory array read mode is the default state after power up or after a reset operation. to perform a read operation, please re - fer to read operation in the bus operations section above. if the device receives an erase suspend command while in the sector erase state, the erase operation will pause (after a time delay not exceeding 20us) and the device will enter erase-suspended read mode. while in the erase-suspended read mode, data can be programmed or read from any sector not being erased. reading from addresses within sector(s) being erased will only return the contents of the status register, which is in fact how the current status of the device can be determined. if a program command is issued to any inactive (not currently being erased) sector during erase-suspended read mode, the device will perform the program operation and automatically return to erase-suspended read mode after the program operation completes successfully. while in erase-suspended read mode, an erase resume command must be issued by the system to reactivate the erase operation. the erase operation will resume from where is was suspended and will continue until it completes successfully or another erase suspend command is received. after the memory device completes an embedded operation (automatic chip erase, sector erase, or program) successfully, it will automatically return to read mode and data can be read from any address in the array. if the embedded operation fails to complete, as indicated by status register bit q5 (exceeds time limit fag) going high during the operations, the system must perform a reset operation to return the device to read mode. there are several states that require a reset operation to return to read mode: 1. a program or erase failure--indicated by status register bit q5 going high during the operation. failures dur - ing either of these states will prevent the device from automatically returning to read mode. 2. the device is in auto select mode or cfi mode. these two states remain active until they are terminated by a reset operation. in the two situations above, if a reset operation (either hardware reset or software reset command) is not per - formed, the device will not return to read mode and the system will not be able to read array data. automatic programming of the memory array the device provides the user the ability to program the memory array in byte mode or word mode. as long as the users enters the correct cycle defned in the table 3 (including 2 unlock cycles and the a0h program com - mand), any byte or word data provided on the data lines by the system will automatically be programmed into the array at the specifed location. after the program command sequence has been executed, the internal write state machine (wsm) automatically executes the algorithms and timings necessary for programming and verifcation, which includes generating suit - able program pulses, checking cell threshold voltage margins, and repeating the program pulse if any cells do not pass verifcation or have low margins. the internal controller protects cells that do pass verifcation and mar - gin tests from being over-programmed by inhibiting further program pulses to these passing cells as weaker cells continue to be programmed. with the internal wsm automatically controlling the programming process, the user only needs to enter the pro - gram command and data once. p/n:pm1509 rev. 1.5, oct. 21, 2015 mx29gl320e t/b mx29gl320e h/l 25 command operations (cont'd) automatic programming of the memory array (cont'd) programming will only change the bit status from "1" to "0". it is not possible to change the bit status from "0" to "1" by programming. this can only be done by an erase operation. furthermore, the internal write verifcation only checks and detects errors in cases where a "1" is not successfully programmed to "0". any commands written to the device during programming will be ignored except hardware reset or program sus - pend. hard ware reset will terminate the program operation after a period of time no more than 10us. when the embedded program algorithm is complete or the program operation is terminated by a hardware reset, the de - vice will return to read mode. program suspend ready, the device will enter program suspend read mode. after the embedded program operation has begun, the user can check for completion by reading the following bits in the status register: note: ry/by# is an open drain output pin and should be connected to vcc through a high value pull-up resistor. erasing the memory array there are two types of erase operations performed on the memory array -- sector erase and chip erase. in the sector erase operation, one or more selected sectors may be erased simultaneously. in the chip erase operation, the complete memory array is erased except for any protected sectors. more details of the protected sectors are explained in section 5. sector erase the sector erase operation is used to clear data within a sector by returning all of its memory locations to the "1" state. it requires six command cycles to initiate the erase operation. the frst two cycles are "unlock cycles", the third 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 has been issued, an internal 50us time-out counter is started. until this counter reaches zero, additional sector addresses and sector erase commands may be is - sued thus allowing multiple sectors to be selected and erased simultaneously. after the 50us time-out counter has expired, no new commands will be accepted and the embedded sector erase operation will begin. note that the 50us timer-out counter is restarted after every erase command sequence. if the user enters any command other than sector erase or erase suspend during the time-out period, the erase operation will abort and the de - vice will return to read mode. after the embedded sector erase operation begins, all commands except erase suspend will be ignored. the only way to interrupt the operation is with an erase suspend command or with a hardware reset. the hardware reset will completely abort the operation and return the device to read mode. status q7 *1 q6 *1 q5 q1 ry/by# (note)

can determine the status of the embedded sector erase operation by the following methods: chip erase the chip erase operation is used erase all the data within the memory array. all memory cells containing a "0" will be returned to the erased state of "1". this operation requires 6 write cycles to initiate the action. the frst two cycles are "unlock" cycles, the third is a confguration cycle, the fourth and ffth are also "unlock" cycles, and the sixth cycle initiates the chip erase operation. during the chip erase operation, no other software commands will be accepted, but if a hardware reset is re - ceived or the working voltage is too low, that chip erase will be terminated. after chip erase, the chip will auto - matically return to read mode. the system can determine the status of the embedded chip erase operation by the following methods: *1: ry/by# is open drain output pin and should be connected to vcc through a high value pull-up resistor. note: 1. the q3 status bit is the 50us time-out indicator . when q3=0, the 50us time-out counter has not yet reached zero and a new sector erase command may be issued to specify the address of another sector to be erased. when q3=1, the 50us time-out counter has expired and the sector erase operation has already begun. erase suspend is the only valid command that may be issued once the embedded erase operation is underway. 2. r y/by# is open drain output pin and should be connected to vcc through a high value pull-up resistor. 3. when an attempt is made to erase only protected sector(s), the erase operation will abort thus preventing any data changes in the protected sector(s). q7 will output "0" and q6 will toggle briefy (100us or less) before aborting and returning the device to read mode. if unprotected sectors are also specifed, however, they will be erased normally and the protected sector(s) will remain unchanged. 4. q2 is a localized indicator showing a specifed sector is undergoing erase operation or not. q2 toggles when user reads at addresses where the sectors are actively being erased (in erase mode) or to be erased (in erase suspend mode). status q7 q6 q5 q3 *1 q2 ry/by# *2 time-out period 0

tem issues an erase suspend command during the 50us time-out period following a sector erase command, the time-out period will terminate immediately and the device will enter erase-suspended read mode. if the system issues an erase suspend command after the sector erase operation has already begun, the device will not enter erase-suspended read mode until 20us time has elapsed. the system can determine if the device has entered the erase-suspended read mode through q6, q7, and ry/by#. after the device has entered erase-suspended read mode, the system can read or program any sector(s) ex - cept those being erased by the suspended erase operation. reading any sector being erased or programmed will return the contents of the status register. whenever a suspend command is issued, user must issue a re - sume command and check q6 toggle bit status, before issue another erase command. the system can use the status register bits shown in the following table to determine the current state of the device: command operations (cont'd) erase suspend/resume when the device has suspended erasing, user can execute the command sets except sector erase and chip erase, such as read silicon id, sector protect verify, program, cfi query and erase resume. sector erase resume the sector erase resume command is valid only when the device is in erase-suspended read mode. after erase resumes, the

table 3 (two unlock cycles followed by the automatic select command 90h) to enter automatic select mode. after entering automatic select mode, the user can query the manufacturer id, device id, security sector locked status, or sector protected status multiple times without issuing a new automatic select command. while in automatic select mode, issuing a reset command (f0h) will return the device to read mode (or ease- suspended read mode if erase-suspend was active) or program suspended read mode if program suspend was active. another way to enter automatic select mode is to use one of the bus operations shown in table 2. bus operation_2. after the high voltage (vhv) is removed from the a9 pin, the device will automatically return to read mode or erase-suspended read mode. automatic select command sequence automatic select mode is used to access the manufacturer id, device id and to verify whether or not secured silicon is locked and 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 select mode and back to read array. the following table shows the identifcation code with

write protection bits (spb) the solid write protection bits (spb) are nonvolatile bit with the same endurances as the flash memory. each spb is assigned to each sector individually. the spb is preprogrammed, and verified prior to erasure are managed by the device, so system monitoring is not necessary. when spb is set to 0, the associated sector may be protected, preventing any program or erase operation on this sector. whether the sector is protected depends also upon the value of the uspb, as described elsewhere. the spb bits are set individually by spb program command. however, it cannot be cleared individually. issuing the all spb erase command will erase all spb in the same time. during spb programming period, the read and write operations are disabled for normal sector until exiting this mode. to unprotect a protected sector, the spb lock bit must be cleared frst by using a hardware reset or a power-up cycle. after the spb lock bit is cleared, the spb status can be changed to the desired settings. to lock the solid protection bits after the modifcation has fnished, the spb lock bit must be set once again. to verify the state of the spb for a given sector, issuing a spb status read command to the device is required. refer to the fow chart for details in figure 3. 2.2 dynamic write protection bits (dpb) the dynamic protection features a volatile type protection to each individual sector. it can protect sectors from being unintentionally changed, and is easy to disable. all dynamic write protection bit (dpb) can be modifed individually. dpbs protect the unprotected sectors with their spbs cleared. to modify the dpb status by issuing the dpb set (programmed to 0) or dpb clear (erased to 1) commands, and place each sector in the protected or unprotected state seperately. after the dpb clear command is issued (erased to 1), the sector may be modifed depending on the spb state of that sector . the dpbs are default to be erased to 1 when

the uspbs can be set (to 0) or cleared (to 1) as often as needed. the hardware reset will reset uspb/dpb to their default values. 2. to change the protected sector status of solid write protect bit, users don't need to clear all spbs. the users can just implement software to set corresponding uspb to "0", in which the corresponding dpb status is cleared too. consequently, the original solid write protect status of protected sectors can be temporarily changed. 1rwh63%surudphudvhvwdwxvsroolqrzfkduwfkhfn4wrohzkhq4vwrswrohwkhuhdgvwdwxvlv irusurudpiruhudvhrwkhuzlvhwkhvwdwxvlvidlodqgh[lw p/n:pm1509

requested before modifying spb lock bit status. when device is under password protection mode, the spb lock bit is set as 0, after a power-up cycle or reset command. a correct password is required for password unlock command to unlock the spb lock bit. await 2us is necessary to unlock the device after a valid password is given. after that, the spb bits are allowed to be changed. the password unlock command is issued slower than 2 s every time, to prevent hacker from trying all the 64-bit password combinations. there are a few steps to start password protection mode: (1). set a 64-bit password for verifcation before entering the password protection mode. this verifcation is only allowed in password programming. (2). set the password protection mode lock bit to0 to activate the password protection mode. once the password protection mode lock bit is programmed, the programmed q2 bit can not be erased any more and the device will remain permanently in password protection mode. the previous set 64-bit password can not be retrieved or programmed. all the commands to the password-protected address will also be disabled. all the combinations of the 64-bit password can be used as a password, and programming the password does not require special address. the password is defaulted to be all 1 when shipped from the factory. under password program command, only "0" can be programmed. in order to prevent access, the password mode locking bit must be set after the password is programmed and verifed. to set the password mode lock bit will prevent this 64-bits password to be read on the data bus. any modifcation is impossible then, and the password can not be checked anymore after the password mode lock bit is set. 3. solid protection bit lock bit the solid protection bit lock bit (spblk) is assigned to control all spb status. it is an unique and volatile. when spblk=0 (set), all spbs are locked and can not be changed. when spblk=1 (cleared), all spbs are allowed to be changed. there is no software command sequence requested to unlock this bit, unless the device is in the password protection mode. to clear the spb lock bit, just execute a hardware reset or a power-up cycle. in order to prevent modifcation, the spb lock bit must be set (spblk=0) after all spbs are set to desired status. p/n:pm1509
