FUNCTIONAL OPERATION DESCRIPTION
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 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 the
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 temporarily after a
period of time no more than Tready 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 sus-
pend, if user wants to read the data in the sectors being erased, the device will output status data onto the out-
put. 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.
ACCELERATED PROGRAM OPERATION
The accelerated program can improve programming performance compared with word/byte program. By apply-
ing Vhv on WP#/ACC pin, the device will enter accelerated program and draw current no more than Icp1 from
WP#/ACC pin. Removing the Vhv from WP#/ACC pin will put the device back to normal operation (not acceler-
ated).

MX29LV640E 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 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
±
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 memo-
ry will be reset during system reset and allows system to read boot code from flash memory.
SECTOR GROUP PROTECT OPERATION
When a sector group is protected, program or erase operation will be disabled on these sectors. MX29LV640E T/
B provides two methods for sector group protection.
Once the sector group is protected, the sector group remains protected until next chip unprotect, or is temporar-
ily unprotected by asserting RESET# pin at Vhv. Refer to temporary sector group unprotect operation for further
details.
The first method is by applying Vhv on RESET# pin. Refer to Figure 13 for timing diagram and Figure 14 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
MX29LV640E 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
groups are unprotected when shipped from the factory.
The first method is by applying Vhv on RESET# pin. Refer to Figure 13 for timing diagram and Figure 14 for al-
gorithm of the operation.
The other method is asserting Vhv on A9 and OE# pins, with A6 at Vih and CE# at Vil. The unprotect operation
begins at the falling edge of WE# and terminates at the rising edge. Contact Macronix for details.
TEMPORARY SECTOR GROUP 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.

MX29LV640E T/B
WRITE PROTECT (WP#)
Another function of the WP#/ACC pin is to provide write protection function on the two outermost 8 Kbyte boot
sectors. When ViL is asserted on WP#/ACC pin, the two boot sectors are protected regardless of the previous
state of protection implemented by aforementioned Sector Group Protect/Chip Unprotect. For MX29LV640ET,
the two outermost sectors are the two boot sectors of the highest addresses. For MX29LV640EB, the two outer-
most sectors are the two boot sectors of the lowest addresses.
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 out-
put Macronix Manufacture ID C2H. When A0 is high, device will output Device ID. In read silicon ID mode, issu-
ing 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 GROUP PROTECT STATUS OPERATION
MX29LV640E 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 Vhv on
A9 pin, Vih on WE# and A1 pins, Vil on CE#, OE#, A6 and A0 pins, and sector address on A12 to A21 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.
SECURITY SECTOR FLASH MEMORY REGION
The Security Sector region is an extra OTP memory space of 128 words in length. The security sectors can be
locked upon shipping from factory, or it can be locked by customer after shipping. Customer can issue Security
Sector Factory Protect Verify and/or Security Sector Protect Verify to query the lock status of the device.
In factory-locked device, security sector region is protected when shipped from factory and the security silicon
sector indicator bit is set to "1". In customer lockable device, security sector region is unprotected when shipped
from factory and the security silicon indicator bit is set to "0".
Factory Locked: Security Sector Programmed and Protected at the Factory
In a factory locked device, the security silicon region is permanently locked after shipping from factory. The de-
vice will have a 16-byte (8-word) ESN in the security region. In bottom boot device : 000000h - 000007h (for
MX29LV640EB). In Top boot device : 3FFF70h - 3FFF77h (for MX29LV640ET).

Customer Lockable: Security Sector NOT Programmed or Protected at the Factory
When the security feature is not required, the security region can act as an extra memory space.
Security silicon sector can also be protected by two methods. Note that once the security silicon sector is pro-
tected, there is no way to unprotect the security silicon sector and the content of it can no longer be altered.
The first method is to write a three-cycle command of Enter Security Region, and then follow the sector group
protect algorithm as illustrated in Figure 14, except that RESET# pin may at either Vih or Vhv.
The other method is to write a three-cycle command of Enter Security Region, and then follow the alternate
method of sector protect with A9, OE# at Vhv.
After the security silicon is locked and verified, system must write Exit Security Sector Region, go through a pow-
er cycle, or issue a hardware reset to return the device to read normal array mode.
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 Vlko. This prevents data from spuriously
altered. The device automatically resets itself when Vcc is lower than Vlko and write cycles are ignored until Vcc
is greater than Vlko. System must provide proper signals on control pins after Vcc is larger than Vlko to avoid un-
intentional 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.
POWER-UP SEQUENCE
Upon power up, MX29LV640E T/B is placed in read array mode. Furthermore, program or erase operation will
begin only after successful completion of specified command sequences.

MX29LV640E T/B
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.

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
• CFI mode
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, 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 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 secured
silicon is locked and 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.

MX29LV640E T/B
AUTOMATIC PROGRAMMING
The MX29LV640E 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 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 algo-
rithms 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 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.
The typical chip program time at room temperature of the MX29LV640E T/B is less than 45 seconds.
When the embedded program operation is on going, user can confirm if the embedded operation is finished or
not by the following methods:

*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.

MX29LV640E T/B
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 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

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 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 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 erase operation is on going, user can confirm if the embedded operation is finished or not
by the following methods:

Note :
1. The status Q3 is the time-out period indicator. When Q3=0, the device is in time-out period and is accept-
able to another sector address to be erased. When Q3=1, the device is in erase operation and only erase
suspend is valid.

MX29LV640E T/B
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.
4. Q2 is a localized indicator showing a specified 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). When a sector has been completely erased, Q2 stops toggling at the sector even when the
device is still in erase operation for remaining selected sectors. At that circumstance, Q2 will still toggle when
device is read at any other sector that remains to be erased.
SECTOR ERASE SUSPEND
During sector erasure, sector erase suspend is the only valid command. 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 be-
ing operated, device will suspend the ongoing erase operation, and after the Tready1 (<=20us) suspend finishes
and the device will enter erase-suspended read array mode. User can judge if the device has finished erase sus-
pend through Q6, Q7, and RY/BY#.
After device has entered erase-suspended read array mode, user can read other sectors not at erase suspend
by the speed of Taa; while reading the sector in erase-suspend mode, device will output its status. Whenever a
suspend command is issued, user must issue a resume 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:

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
Sector erase resume command is valid only when the device is in erase suspend state. After erase resume, user
can issue another erase suspend command, but there should be a 4ms interval between erase resume and the
next erase suspend. If user issue infinite suspend-resume loop, or suspend-resume exceeds 1024 times, the
time for erasing will increase.

COMMON FLASH MEMORY INTERFACE (CFI) MODE
QUERY COMMAND AND COMMON FLASH INTERFACE (CFI) MODE
MX29LV640E T/B features CFI mode. Host system can retrieve the operating characteristics, structure and ven-
dor-specified information such as identifying information, memory size, byte/word configuration, operating voltag-
es and timing information of this device by CFI mode. The device enters the CFI Query mode when the system
writes the CFI Query command, 98H, to address 55H/AAH (depending on Word/Byte mode) any time the device
is ready to read array data. The system can read CFI information at the addresses given in Table 4. A reset com-
mand is required to exit CFI mode and go back to ready array mode or erase suspend mode. The system can
write the CFI Query command only when the device is in read mode, erase suspend, standby mode or automatic
select mode. The CFI unused area is Macronix's reserved.
