MX29LV065B
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 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.
ACCELERATED PROGRAM OPERATION
The accelerated program can improve programming performance compared with byte program. By applying Vhv on
ACC pin, the device will enter accelerated program and draw current no more than Icw from ACC pin. Removing the
Vhv from ACC pin will put the device back to normal operation (not accelerated).
P/N:PM1082
REV. 1.7, APR. 18, 2008

MX29LV065B
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 GROUP PROTECT OPERATION
When a sector group is protected, program or erase operation will be disabled on these sectors. MX29LV065B provides
two methods for sector group protection.
Once the sector group is protected, the sector group remains protected until next chip unprotect, or is temporarily
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
MX29LV065B 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 sector 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 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 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 operation once
Vhv is removed from RESET# pin and previously protected sectors are again protected.

MX29LV065B
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 GROUP PROTECT STATUS OPERATION
MX29LV065B 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.
SECURITY SECTOR FLASH MEMORY REGION
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 device will
have a 16-byte ESN in the security region. In device : 000000h - 00000Fh.
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. The security silicon
sector can be read, programmed at address 000010h-00008Fh.
Security silicon sector can also be protected by two methods. Note that once the security silicon sector is protected,
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
P/N:PM1082
REV. 1.7, APR. 18, 2008
14
MX29LV065B
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 power
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 2.5V. This prevents data from spuriously
altered. The device automatically resets itself when Vcc is lower than 2.5V and write cycles are ignored until Vcc is
greater than 2.5V. System must provide proper signals on control pins after Vcc is larger than 2.5V 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.
POWER-UP SEQUENCE
Upon power up, MX29LV065B is placed in read array mode. 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.

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 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 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.

MX29LV065B
AUTOMATIC PROGRAMMING
The MX29LV065B can provide the user program function by the form of Byte-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 MX29LV065B is less than 42 seconds.
When the embedded program operation is on going, user can confirm if the embedded operation is finished or not by the

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.

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 timeout 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 erase 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.

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 erasesuspended 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 (<=20us) suspend finishes and the device will enter
erase-suspended read array mode. User can judge if the device has finished erase suspend 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. User can use Q6 and Q2
to judge the sector is erasing or the erase is suspended.

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.
