block diagram description the block diagram 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 la tch and buffer" to latch the external address pins a0-am(a22). the internal addresses are output from this block to the main array and decoders composed of "x-decoder", "y -decoder", "y -pass ga te", and "flash ar - ray". 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 line s are electrically connected to the "sense amplifier" and "pgm da ta hv" se - lectively through the y -pass gates. sense amplifiers are used to read out the contents of the fash memo - ry, while the "pgm da ta 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 receives data from sense amplifiers and drives the output pads accordingly . in the last cycle of program command, the i/o buffer transmits the data on q0-q15/a-1 to "program da ta la tch", which controls the high power drivers in "pgm da ta hv" to selectively program the bits in a word or byte according to the user in - put pattern. the "program/erase high vol tage" block comprises the circuits to generate and deliver the necessary high voltage to the x-decoder, flash arra y, and "pgm da ta hv" blocks. the logic control module com - prises of t he " write st ate ma chine, w sm", " state reg ister", " command da ta deco der", and "command da ta la tch". when the user issues a command by toggling we#, the command on q0-q15/a-1 is latched in the command da ta la tch and is decoded by the command da ta decoder. the st ate register receives the command and records the current state of the device. the wsm implements the in - ternal algorithm s 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 w ord mode (x16). the details of the ad - dress ranges and the corresponding sector addresses are shown in table 1 . p/n:pm1500 rev. 1.8, nov. 13, 2013 mx29gl128e 7 table 1: mx29gl128e sector group architecture sector size sector sector

array or status register location by pro - viding its addre ss on the address pins and simultaneous ly enabling the chip by driving ce# & oe# low , and we# high. after the t ce and t oe timing requirements have been met, the system can read the contents of the addressed location by reading the data (i/o) pins. if either the ce# or oe# is held high, the outputs will remain tri-stated and no data will appear on the output pins. page read this device is able to conduc t 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 t aa or t ce, following by tpa for the rest of the page read time. when ce# toggles, access time is t aa or t ce. 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

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 t rp 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 t ready1 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:pm1500 rev. 1.8, nov. 13, 2013 mx29gl128e 13 functional operation description

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 64bytes/32words in a programming operation. t o trigger the w rite buf fer programming, start by the frst two unlock cycles, then third cycle writes the w rite buf fer load command at the destined programming sec - tor

or data, the "write-buf fer-page" is selected. the following data should be within the above men - tioned page. the "write-buffer-page" is selected by choosing address amax-a5. "write-buffer-page" address has to be the same for all address/ data write into the write buf fer. if not, operation will abor t. 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-buf fer can be suspended or resumed by the standard commands, once the write buf fer programming operation is fnished,

for selected sectors. please refer to table 1 which show all sector assignments. during the protection operatio n, 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 aut omatic select command sequence in the command opera tions section for details

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. t he syst em must provide proper signals on cont rol pins af ter vcc rises above vlko t o avoid unint entional 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 ef fective write cycle. logical inhibit a valid write cycle requires both ce# and we# at v il with oe# at v ih. w rite cycle is ignored when either ce# at vih, we# at vih, or oe# at vil. p/n:pm1500 rev. 1.8, nov. 13, 2013 mx29gl128e 16 functional operation description (cont'd) power-up sequence upon power up, the device is placed in read mode. furthermore, program or erase operation will begin only after successful completion of specifed command sequences. power-up write inhibit when we#, ce# is held at v il and oe# is held at v ih during power up, the device ignores the frst command on the rising edge of we#. power supply decoupling a 0.1uf

state after power up or after a reset operation. t o 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-susp ended 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 operatio n 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 automatica lly 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 w ord mode. as long as the users enters the correct cycle defned in the table 3 (including 2 unlock cycles and the a0h program command ), 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 program ming 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:pm1500 rev. 1.8, nov. 13, 2013 mx29gl128e 18 command operations (cont'd) automatic programming of the memory array (cont'd) programming will only chang e 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 advanced sector protection/un-protection . 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) in progress q7# toggling 0 0 0

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 opera tion, 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. notes: 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 q 3=1, t he 50us t ime-out c ounter has ex pired and t he s ector e rase oper ation has alr eady begun. e rase suspend is the only valid command that may be issued once the embedded erase operation is underway. 2. ry/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 unpro tected 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 toggling 0 0 toggling 0 in progress

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

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

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. t o 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. t o 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 frst shipped from factory. p/n:pm1500 rev. 1.8, nov. 13, 2013 mx29gl128e

are unique for each sector and can be individually modifed. software can temporarily unprotect write protect sectors despite of spb's property when dpbs are cleared. while the uspb is set (to 0), the corresponding sector's spb property is masked. notes: 1. upon power up, the uspbs are cleared (all 1). 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. t o 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. note: spb program/erase status polling fowchart: check q6 toggle, when q6 stop toggle, the read status is 00h /01h (00h for program/ 01h for erase), otherwise, the status is fail and exit. p/n:pm1500 rev. 1.8, nov. 13, 2013 mx29gl128e 28 4. password protection method the security level of password protection method is higher than the solid protection mode. the 64 bit password is reque sted 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 require d for password unlock command to unlock the spb lock bit. a wait 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-bi t 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
