GENERAL DESCRIPTION
The MX29LA129M H/L is a 128-mega bit Flash memory
organized as 16M bytes of 8 bits or 8M words of 16 bits.
MXIC's Flash memories offer the most cost-effective and
reliable read/write non-volatile random access memory.
The MX29LA129M H/L is packaged in 56-pin TSOP. It is
designed to be reprogrammed and erased in system or in
standard EPROM programmers.
The standard MX29LA129M H/L offers access time as
fast as 90ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, the MX29LA129M H/L has separate chip enable
(CEx) and output enable (OE#) controls.
MXIC's Flash memories augment EPROM functionality

MX29LA129M H/L
with in-circuit electrical erasure and programming. The
MX29LA129M H/L uses a command register to manage
this functionality.
AUTOMATIC SECTOR ERASE
The MX29LA129M H/L is sector(s) erasable using MXIC's
Auto Sector Erase algorithm. Sector erase modes allow
sectors of the array to be erased in one erase cycle. The
Automatic Sector Erase algorithm automatically programs
the specified sector(s) prior to electrical erase. The timing and verification of electrical erase are controlled internally within the device.
MXIC Flash technology reliably stores memory contents
even after 100,000 erase and program cycles. The MXIC
cell is designed to optimize the erase and program
mechanisms. In addition, the combination of advanced
tunnel oxide processing and low internal electric fields
for erase and programming operations produces reliable
cycling. The MX29LA129M H/L uses a 2.7V to 3.6V
VCC supply to perform the High Reliability Erase and
auto Program/Erase algorithms.
AUTOMATIC ERASE ALGORITHM
MXIC's Automatic Erase algorithm requires the user to
write commands to the command register using standard microprocessor write timings. The device will automatically pre-program and verify the entire array. Then
the device automatically times the erase pulse width,
provides the erase verification, and counts the number
of sequences. A status bit toggling between consecutive read cycles provides feedback to the user as to the
status of the programming operation.
The highest degree of latch-up protection is achieved
with MXIC's proprietary non-epi process. Latch-up protection is proved for stresses up to 100 milliamperes on
address and data pin from -1V to VCC + 1V.
AUTOMATIC PROGRAMMING
The MX29LA129M H/L is byte/word/page programmable
using the Automatic Programming algorithm. The Automatic Programming algorithm makes the external system do not need to have time out sequence nor to verify
the data programmed.
Register contents serve as inputs to an internal statemachine which controls the erase and programming circuitry. During write cycles, the command register internally latches address and data needed for the programming and erase operations. During a system write cycle,
addresses are latched on the falling edge, and data are
latched on the rising edge of WE# .
AUTOMATIC PROGRAMMING ALGORITHM
MXIC's Flash technology combines years of EPROM
experience to produce the highest levels of quality, reliability, and cost effectiveness. The MX29LA129M H/L
electrically erases all bits simultaneously using FowlerNordheim tunneling. The bytes are programmed by using the EPROM programming mechanism of hot electron injection.
MXIC's Automatic Programming algorithm require the user
to only write program set-up commands (including 2 unlock write cycle and A0H) and a program command (program data and address). The device automatically times
the programming pulse width, provides the program verification, and counts the number of sequences. A status
bit similar to DATA# polling and a status bit toggling between consecutive read cycles, provide feedback to the
user as to the status of the programming operation.
During a program cycle, the state-machine will control
the program sequences and command register will not
respond to any command set. During a Sector Erase
cycle, the command register will only respond to Erase
Suspend command. After Erase Suspend is completed,
the device stays in read mode. After the state machine
has completed its task, it will allow the command register to respond to its full command set.
AUTOMATIC CHIP ERASE
The entire chip is bulk erased using 50 ms erase pulses
according to MXIC's Automatic Chip Erase algorithm. The
Automatic Erase algorithm automatically programs the
entire array prior to electrical erase. The timing and verification of electrical erase are controlled internally within
the device.

MX29LA129M H/L
consists of the address bits required to uniquely select a
sector. The Writing specific address and data commands
or sequences into the command register initiates device
operations. Table 1 defines the valid register command
sequences. Writing incorrect address and data values or
writing them in the improper sequence resets the device
to reading array data. Section has details on erasing a
sector or the entire chip, or suspending/resuming the erase
operation.
REQUIREMENTS FOR READING ARRAY
DATA
To read array data from the outputs, the system must
drive the CEx and OE# pins to VIL. CEx is the power
control and selects the device. OE# is the output control
and gates array data to the output pins. WE# should remain at VIH.
The internal state machine is set for reading array data
upon device power-up, or after a hardware reset. This
ensures that no spurious alteration of the memory content occurs during the power transition. No command is
necessary in this mode to obtain array data. Standard
microprocessor read cycles that assert valid address on
the device address inputs produce valid data on the device data outputs. The device remains enabled for read
access until the command register contents are altered.
After the system writes the Automatic Select command
sequence, the device enters the Automatic Select mode.
The system can then read Automatic Select codes from
the internal register (which is separate from the memory
array) on Q7-Q0. Standard read cycle timings apply in
this mode. Refer to the Automatic Select Mode and Automatic Select Command Sequence section for more
information.
PAGE MODE READ
ICC2 in the DC Characteristics table represents the active current specification for the write mode. The "AC
Characteristics" section contains timing specification
table and timing diagrams for write operations.
The MX29LA129M H/L offers "fast page mode read" function. This mode provides faster read access speed for
random locations within a page. The page size of the
device is 4 words/8 bytes. The appropriate page is selected by the higher address bits A1~A2(Word Mode)/
A0~A2(Byte Mode) This is an asynchronous operation;
the microprocessor supplies the specific word location.
WRITE BUFFER
Write Buffer Programming allows the system to write a
maximum of 16 words/32 bytes in one programming operation. This results in faster effective programming time
than the standard programming algorithms. See "Write
Buffer" for more information.
The system performance could be enhanced by initiating
1 normal read and 3 fast page read (for word mode A1A2) or 7 fast page read (for byte mode A0~A2). When
CEx is deasserted and reasserted for a subsequent access, the access time is tACC or tCE. Fast page mode
accesses are obtained by keeping the "read-page addresses" constant and changing the "intra-read page"
addresses.
WRITING COMMANDS/COMMAND
QUENCES
ACCELERATED PROGRAM OPERATION
The device offers accelerated program operations through
the ACC function. This is one of two functions provided
by the ACC pin. This function is primarily intended to
allow faster manufacturing throughput at the factory.
SE-
If the system asserts VHH on this pin, the device automatically enters the aforementioned Unlock Bypass
mode, temporarily unprotects any protected sectors, and
uses the higher voltage on the pin to reduce the time
required for program operations. The system would use
a two-cycle program command sequence as required by
the Unlock Bypass mode. Removing VHH from the ACC
pin must not be at VHH for operations other than accelerated programming, or device damage may result.
To program data to the device or erase sectors of memory,
the system must drive WE# and CEx to VIL, and OE# to
VIH.
An erase operation can erase one sector, multiple sectors, or the entire device. Table indicates the address
space that each sector occupies. A "sector address"

MX29LA129M H/L
but not within VSS±0.3V, the standby current will be
greater.
STANDBY MODE
When using both pins of CEx and RESET#, the device
enter CMOS Standby with both pins held at VCC ± 0.3V.
If CEx and RESET# are held at VIH, but not within the
range of VCC ± 0.3V, the device will still be in the standby
mode, but the standby current will be larger. During Auto
Algorithm operation, VCC active current (ICC2) is required
even CEx = "H" until the operation is completed. The
device can be read with standard access time (tCE) from
either of these standby modes, before it is ready to read
data.
The RESET# pin may be tied to system reset circuitry.
A system reset would that also reset the Flash memory,
enabling the system to read the boot-up firmware from
the Flash memory.
If RESET# is asserted during a program or erase
operation, the RY/BY# pin remains a "0" (busy) until the
internal reset operation is complete, which requires a time
of tREADY (during Embedded Algorithms). The system
can thus monitor RY/BY# to determine whether the reset
operation is complete. If RESET# is asserted when a
program or erase operation is completed within a time of
tREADY (not during Embedded Algorithms). The system
can read data tRH after the RESET# pin returns to VIH.
AUTOMATIC SLEEP MODE
The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this
mode when address remain stable for tACC+30ns. The
automatic sleep mode is independent of the CEx, WE#,
and OE# control signals. Standard address access timings provide new data when addresses are changed. While
in sleep mode, output data is latched and always available to the system. ICC4 in the DC Characteristics table
represents the automatic sleep mode current specification.
Refer to the AC Characteristics tables for RESET#
parameters and to Figure 3 for the timing diagram.
SECTOR GROUP PROTECT OPERATION
The MX29LA129M H/L features hardware sector group
protection. This feature will disable both program and
erase operations for these sector group protected. In
this device, a sector group consists of four adjacent sectors which are protected or unprotected at the same time.
To activate this mode, the programming equipment must
force VID on address pin A10 and control pin OE#, (suggest VID = 12V) A7 = VIL and CEx = VIL. (see Table 2)
Programming of the protection circuitry begins on the
falling edge of the WE# pulse and is terminated on the
rising edge. Please refer to sector group protect algorithm and waveform.
OUTPUT DISABLE
With the OE# input at a logic high level (VIH), output
from the devices are disabled. This will cause the output
pins to be in a high impedance state.
RESET# OPERATION
MX29LA129M H/L also provides another method. Which
requires VID on the RESET# only. This method can be
implemented either in-system or via programming equipment. This method uses standard microprocessor bus
cycle timing.
The RESET# pin provides a hardware method of resetting
the device to reading array data. When the RESET# pin
is driven low for at least a period of tRP, the device
immediately terminates any operation in progress,
tristates all output pins, and ignores all read/write
commands for the duration of the RESET# pulse. The
device also resets the internal state machine to reading
array data. The operation that was interrupted should be
reinitiated once the device is ready to accept another
command sequence, to ensure data integrity
To verify programming of the protection circuitry, the programming equipment must force VID on address pin A10
( with CEx and OE# at VIL and WE# at VIH). When
A2=1, it will produce a logical "1" code at device output
Q0 for a protected sector. Otherwise the device will produce 00H for the unprotected sector. In this mode, the
addresses, except for A2, are don't care. Address locations with A2 = VIL are reserved to read manufacturer
and device codes. (Read Silicon ID)
Current is reduced for the duration of the RESET# pulse.
When RESET# is held at VSS±0.3V, the device draws
CMOS standby current (ICC4). If RESET# is held at VIL

last protected or unprotect using the method described in
"Sector/Sector Group Protection and Chip Unprotect".
It is also possible to determine if the group is protected
in the system by writing a Read Silicon ID command.
Performing a read operation with A2=VIH, it will produce
a logical "1" at Q0 for the protected sector.
Note that the WP# pin must not be left floating or unconnected; inconsistent behavior of the device may result.
CHIP UNPROTECT OPERATION
TEMPORARY SECTOR GROUP UNPROTECT
OPERATION
The MX29LA129M H/L also features the chip unprotect
mode, so that all sectors are unprotected after chip
unprotect is completed to incorporate any changes in
the code. It is recommended to protect all sectors before
activating chip unprotect mode.
This feature allows temporary unprotect of previously
protected sector to change data in-system. The Temporary Sector Unprotect mode is activated by setting the
RESET# pin to VID(11.5V-12.5V). During this mode, formerly protected sectors can be programmed or erased
as unprotect sector. Once VID is remove from the RESET# pin, all the previously protected sectors are protected again.
To activate this mode, the programming equipment must
force VID on control pin OE# and address pin A10. The
CEx pins must be set at VIL. Pins A7 must be set to
VIH. (see Table 2) Refer to chip unprotect algorithm and
waveform for the chip unprotect algorithm. The unprotect
mechanism begins on the falling edge of the WE# pulse
and is terminated on the rising edge.
SILICON ID READ OPERATION
MX29LA129M H/L also provides another method. Which
requires VID on the RESET# only. This method can be
implemented either in-system or via programming equipment. This method uses standard microprocessor bus
cycle timing.
Flash memories are intended for use in applications where
the local CPU alters memory contents. As such, manufacturer and device codes must be accessible while the
device resides in the target system. PROM programmers typically access signature codes by raising A10 to
a high voltage. However, multiplexing high voltage onto
address lines is not generally desired system design practice.
It is also possible to determine if the chip is unprotect in
the system by writing the Read Silicon ID command.
Performing a read operation with A2=VIH, it will produce
00H at data outputs (Q0-Q7) for an unprotect sector. It is
noted that all sectors are unprotected after the chip
unprotect algorithm is completed.
MX29LA129M H/L provides hardware method to access
the silicon ID read operation. Which method requires VID
on A10 pin, VIL on CEx, OE#, A7, and A2 pins. Which
apply VIL on A1 pin, the device will output MXIC's manufacture code of which apply VIH on A1 pin, the device will
output MX29LA129M H/L device code.
WRITE PROTECT (WP#)
The write protect function provides a hardware method
to protect all sectors without using VID.
VERIFY SECTOR GROUP PROTECT STATUS
OPERATION
If the system asserts VIL on the WP# pin, the device
disables program and erase functions in all sectors independently of whether those sectors were protected or
unprotect using the method described in Sector/Sector
Group Protection and Chip Unprotect".
MX29LA129M H/L provides hardware method for sector
group protect status verify. Which method requires VID
on A10 pin, VIH on WE# and A2 pins, VIL on CEx, OE#,
A7, and A1 pins, and sector address on A16 to A23 pins.
Which the identified sector is protected, the device will
output 01H. Which the identified sector is not protect, the
device will output 00H.
If the system asserts VIH on the WP# pin, the device
reverts to whether the sectors were last set to be protected or unprotect. That is, sector protection or
unprotection for the sectors depends on whether they were
P/N:PM1171

MX29LA129M H/L
of main sectors is as normally. This mode of operation
continues until the system issues the Exit Secured Silicon Sector command sequence, or until power is removed
from the device. On power-up, or following a hardware
reset, the device reverts to sending command to sector
SA0.
DATA PROTECTION
The MX29LA129M H/L is designed to offer protection
against accidental erasure or programming caused by
spurious system level signals that may exist during power
transition. During power up the device automatically resets the state machine in the Read mode. In addition,
with its control register architecture, alteration of the
memory contents only occurs after successful completion of specific command sequences. The device also
incorporates several features to prevent inadvertent write
cycles resulting from VCC power-up and power-down transition or system noise.

SECURED SILICON SECTOR
The MX29LA129M H/L features a OTP memory region
where the system may access through a command sequence to create a permanent part identification as so
called Electronic Serial Number (ESN) in the device.
Once this region is programmed, any further modification on the region is impossible. The secured silicon sector is a 128 words in length, and uses a Secured Silicon
Sector Indicator Bit (Q7) to indicate whether or not the
Secured Silicon Sector is locked when shipped from the
factory. This bit is permanently set at the factory and
cannot be changed, which prevent duplication of a factory locked part. This ensures the security of the ESN
once the product is shipped to the field.
FACTORY LOCKED:Secured Silicon Sector
Programmed and Protected At the Factory
In device with an ESN, the Secured Silicon Sector is
protected when the device is shipped from the factory.
The Secured Silicon Sector cannot be modified in any
way. A factory locked device has an 8-word random ESN
at address 000000h-000007h.
CUSTOMER LOCKABLE:Secured Silicon
Sector NOT Programmed or Protected At the
Factory
The MX29LA129M H/L offers the device with Secured
Silicon Sector either factory locked or customer lockable. The factory-locked version is always protected when
shipped from the factory , and has the Secured Silicon
Sector Indicator Bit permanently set to a "1". The customer-lockable version is shipped with the Secured Silicon Sector unprotected, allowing customers to utilize that
sector in any form they prefer. The customer-lockable
version has the secured sector Indicator Bit permanently
set to a "0". Therefore, the Secured Silicon Sector Indicator Bit prevents customer, lockable device from being
used to replace devices that are factory locked.
As an alternative to the factory-locked version, the device
may be ordered such that the customer may program
and protect the 128-word Secured Silicon Sector.
Programming and protecting the Secured Silicon Sector
must be used with caution since, once protected, there
is no procedure available for unprotected the Secured
Silicon Sector area and none of the bits in the Secured
Silicon Sector memory space can be modified in any
way.
The Secured Silicon Sector area can be protected using
one of the following procedures:
The system access the Secured Silicon Sector through
a command sequence (refer to "Enter Secured Silicon/
Exit Secured Silicon Sector command Sequence). After
the system has written the Enter Secured Silicon Sector
command sequence, it may read the Secured Silicon
Sector by using the address normally occupied by the
first sector SA0. Once entry the Secured Silicon Sector
the operation of boot sectors is disabled but the operation
Write the three-cycle Enter Secured Silicon Sector Region
command sequence, and then follow the in-system
sector protect algorithm as shown in Figure 15, except
that RESET# may be at either VIH or VID. This allows insystem protection of the Secured Silicon Sector without
raising any device pin to a high voltage. Note that method
is only applicable to the Secured Silicon Sector.

Write the three-cycle Enter Secured Silicon Sector Region
command sequence, and then alternate method of sector
protection described in the :Sector Group Protection and
Unprotect" section.
POWER SUPPLY DE COUPLING
In order to reduce power switching effect, each device
should have a 0.1uF ceramic capacitor connected between its VCC and GND.
Once the Secured Silicon Sector is programmed, locked
and verified, the system must write the Exit Secured
Silicon Sector Region command sequence to return to
reading and writing the remainder of the array.
LOW VCC WRITE INHIBIT
When VCC is less than VLKO the device does not accept any write cycles. This protects data during VCC
power-up and power-down. The command register and
all internal program/erase circuits are disabled, and the
device resets. Subsequent writes are ignored until VCC
is greater than VLKO. The system must provide the proper
signals to the control pins to prevent unintentional write
when VCC is greater than VLKO.
WRITE PULSE "GLITCH" PROTECTION
Noise pulses of less than 5ns (typical) on CEx or WE#
will not initiate a write cycle.
LOGICAL INHIBIT
Writing is inhibited by holding any one of OE# = VIL, CEx
= VIH or WE# = VIH. To initiate a write cycle CEx and
WE# must be a logical zero while OE# is a logical one.
POWER-UP SEQUENCE
The MX29LA129M H/L powers up in the Read only mode.
In addition, the memory contents may only be altered
after successful completion of the predefined command
sequences.
POWER-UP WRITE INHIBIT
If WE#=CEx=VIL and OE#=VIH during power up, the
device does not accept commands on the rising edge of
WE#. The internal state machine is automatically reset
to the read mode on power-up.

array data (also applies during Erase Suspend).
READING ARRAY DATA
The device is automatically set to reading array data
after device power-up. No commands are required to retrieve data. The device is also ready to read array data
after completing an Automatic Program or Automatic
Erase algorithm.
SILICON ID READ COMMAND SEQUENCE
The SILICON ID READ command sequence allows the
host system to access the manufacturer and devices
codes, and determine whether or not a sector is protected. Table 2 shows the address and data requirements.
This method is an alternative to that shown in Table 1,
which is intended for PROM programmers and requires
VID on address bit A10.
After the device accepts an Erase Suspend command,
the device enters the Erase Suspend mode. The system can read array data using the standard read timings, except that if it reads at an address within erasesuspended sectors, the device outputs status data. After completing a programming operation in the Erase
Suspend mode, the system may once again read array
data with the same exception. See Erase Suspend/Erase
Resume Commands for more information on this mode.
The system must issue the reset command to re-enable the device for reading array data if Q5 goes high, or
while in the automatic select mode. See the "Reset Command" section, next.
The SILICON ID READ command sequence is initiated
by writing two unlock cycles, followed by the SILICON
ID READ command. The device then enters the SILICON ID READ mode, and the system may read at any
address any number of times, without initiating another
command sequence. A read cycle at address XX00h
retrieves the manufacturer code. A read cycle at address
XX01h returns the device code. A read cycle containing
a sector address (SA) and the address 02h returns 01h if
that sector is protected, or 00h if it is unprotected. Refer
to Table for valid sector addresses.
RESET COMMAND
Writing the reset command to the device resets the device to reading array data. Address bits are don't care for
this command.
The system must write the reset command to exit the
automatic select mode and return to reading array data.
The reset command may be written between the sequence cycles in an erase command sequence before
erasing begins. This resets the device to reading array
data. Once erasure begins, however, the device ignores
reset commands until the operation is complete.
BYTE/WORD PROGRAM COMMAND SEQUENCE
The reset command may be written between the sequence cycles in a program command sequence before
programming begins. This resets the device to reading
array data (also applies to programming in Erase Suspend mode). Once programming begins, however, the
device ignores reset commands until the operation is
complete.
The command sequence requires four bus cycles, and
is initiated by writing two unlock write cycles, followed
by the program set-up command. The program address
and data are written next, which in turn initiate the Embedded Program algorithm. The system is not required
to provide further controls or timings. The device automatically generates the program pulses and verifies the
programmed cell margin. Table 3 shows the address and
data requirements for the byte program command sequence.
The reset command may be written between the sequence cycles in an SILICON ID READ command sequence. Once in the SILICON ID READ mode, the reset
command must be written to return to reading array data
(also applies to SILICON ID READ during Erase Suspend).
When the Embedded Program algorithm is complete, the
device then returns to reading array data and addresses
are no longer latched. The system can determine the
status of the program operation by using Q7, Q6, or RY/
BY#. See "Write Operation Status" for information on
these status bits.
If Q5 goes high during a program or erase operation,
writing the reset command returns the device to reading
Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a hard-

MX29LA129M H/L
multiple times, the address/data pair counter will be
decremented for every data load operation. The host system must therefore account for loading a write-buffer location more than once. The counter decrements for each
data load operation, not for each unique write-buffer-address location. Note also that if an address location is
loaded more than once into the buffer, the final data loaded
for that address will be programmed.
ware reset immediately terminates the programming operation. The Byte/Word Program command sequence
should be reinitiated once the device has reset to reading array data, to ensure data integrity.
Programming is allowed in any sequence and across
sector boundaries. A bit cannot be programmed from a
"0" back to a "1". Attempting to do so may halt the operation and set Q5 to "1", or cause the Data# Polling
algorithm to indicate the operation was successful. However, a succeeding read will show that the data is still
"0". Only erase operations can convert a "0" to a "1".
Once the specified number of write buffer locations have
been loaded, the system must then write the Program
Buffer to Flash command at the sector address. Any
other address and data combination aborts the Write
Buffer Programming operation. The device then begins
programming. Data polling should be used while monitoring the last address location loaded into the write buffer.
Q7, Q6, Q5, and Q1 should be monitored to determine
the device status during Write Buffer Programming.
Write Buffer Programming
Write Buffer Programming allows the system write to a
maximum of 16 words/32 bytes in one programming operation. This results in faster effective programming time
than the standard programming algorithms. The Write
Buffer Programming command sequence is initiated by
first writing two unlock cycles. This is followed by a third
write cycle containing the Write Buffer Load command
written at the Sector Address in which programming will
occur. The fourth cycle writes the sector address and
the number of word locations, minus one, to be programmed. For example, if the system will program 6
unique address locations, then 05h should be written to
the device. This tells the device how many write buffer
addresses will be loaded with data and therefore when to
expect the Program Buffer to Flash command. The number of locations to program cannot exceed the size of
the write buffer or the operation will abort.
The write-buffer programming operation can be suspended
using the standard program suspend/resume commands.
Upon successful completion of the Write Buffer Programming operation, the device is ready to execute the next
command.
The Write Buffer Programming Sequence can be aborted
in the following ways:
• Load a value that is greater than the page buffer size
during the Number of Locations to Program step.
• Write to an address in a sector different than the one
specified during the Write-Buffer-Load command.
• Write an Address/Data pair to a different write-bufferpage than the one selected by the Starting Address
during the write buffer data loading stage of the operation.
• Write data other than the Confirm Command after the
specified number of data load cycles.
The fifth cycle writes the first address location and data
to be programmed. The write-buffer-page is selected by
address bits AMAX-4. All subsequent address/data pairs
must fall within the selected-write-buffer-page. The system then writes the remaining address/data pairs into
the write buffer. Write buffer locations may be loaded in
any order.
The abort condition is indicated by Q1 = 1, Q7 = DATA#
(for the last address location loaded), Q6 = toggle, and
Q5=0. A Write-to-Buffer-Abort Reset command sequence
must be written to reset the device for the next operation.
The write-buffer-page address must be the same for all
address/data pairs loaded into the write buffer. (This
means Write Buffer Programming cannot be performed
across multiple write-buffer pages. This also means that
Write Buffer Programming cannot be performed across
multiple sectors. If the system attempts to load programming data outside of the selected write-buffer page, the
operation will abort.
Program Suspend/Program Resume Command
Sequence
The Program Suspend command allows the system to
interrupt a programming operation or a Write to Buffer
programming operation so that data can be read from any
non-suspended sector. When the Program Suspend com-

MX29LA129M H/L
mand is written during a programming process, the device halts the program operation within 15us maximum
(5 us typical) and updates the status bits. Addresses are
not required when writing the Program Suspend command.
AUTOMATIC CHIP/SECTOR ERASE COMMAND
The device does not require the system to preprogram
prior to erase. The Automatic Erase algorithm automatically pre-program and verifies the entire memory for an
all zero data pattern prior to electrical erase. The system
is not required to provide any controls or timings during
these operations. Table 3 shows the address and data
requirements for the chip erase command sequence.
After the programming operation has been suspended,
the system can read array data from any non-suspended
sector. The Program Suspend command may also be
issued during a programming operation while an erase is
suspended. In this case, data may be read from any
addresses not in Erase Suspend or Program Suspend. If
a read is needed from the Secured Silicon Sector area
(One-time Program area), then user must use the proper
command sequences to enter and exit this region.
Any commands written to the chip during the Automatic
Erase algorithm are ignored. Note that a hardware reset
during the chip erase operation immediately terminates
the operation. The Chip Erase command sequence should
be reinitiated once the device has returned to reading
array data, to ensure data integrity.
The system may also write the autoselect command
sequence when the device is in the Program Suspend
mode. The system can read as many autoselect codes
as required. When the device exits the autoselect mode,
the device reverts to the Program Suspend mode, and
is ready for another valid operation. See Autoselect Command Sequence for more information.
The system can determine the status of the erase operation by using Q7, Q6, Q2, or RY/BY#. See "Write Operation Status" for information on these status bits. When
the Automatic Erase algorithm is complete, the device
returns to reading array data and addresses are no longer
latched.
After the Program Resume command is written, the device reverts to programming. The system can determine
the status of the program operation using the Q7 or Q6
status bits, just as in the standard program operation.
See Write Operation Status for more information.
Figure 10 illustrates the algorithm for the erase operation. See the Erase/Program Operations tables in "AC
Characteristics" for parameters, and to Figure 9 for timing diagrams.
SETUP AUTOMATIC CHIP/SECTOR ERASE
Chip erase is a six-bus cycle operation. There are two
"unlock" write cycles. These are followed by writing the
"set-up" command 80H. Two more "unlock" write cycles
are then followed by the chip erase command 10H, or
the sector erase command 30H.
The MX29LA129M H/L contains a Silicon-ID-Read operation to supplement traditional PROM programming
methodology. The operation is initiated by writing the read
silicon ID command sequence into the command register. Following the command write, a read cycle with
A2=VIL,A1=VIL retrieves the manufacturer code. A read
cycle with A2=VIL, A1=VIH returns the device code.
P/N:PM1171
REV. 1.0, FEB. 27, 2006
24
MX29LA129M H/L
device requires a maximum 20us to suspend the sector
erase operation. However, When the Erase Suspend command is written during the sector erase time-out, the
device immediately terminates the time-out period and
suspends the erase operation. After this command has
been executed, the command register will initiate erase
suspend mode. The state machine will return to read
mode automatically after suspend is ready. At this time,
state machine only allows the command register to respond to the Erase Resume, program data to, or read
data from any sector not selected for erasure.
SECTOR ERASE COMMANDS
The Automatic Sector Erase does not require the device
to be entirely pre-programmed prior to executing the Automatic Set-up Sector Erase command and Automatic
Sector Erase command. Upon executing the Automatic
Sector Erase command, the device will automatically
program and verify the sector(s) memory for an all-zero
data pattern. The system is not required to provide any
control or timing during these operations.
When the sector(s) is automatically verified to contain
an all-zero pattern, a self-timed sector erase and verify
begin. The erase and verify operations are complete
when the data on Q7 is "1" and the data on Q6 stops
toggling for two consecutive read cycles, at which time
the device returns to the Read mode. The system is not
required to provide any control or timing during these
operations.
The system can determine the status of the program
operation using the Q7 or Q6 status bits, just as in the
standard program operation. After an erase-suspend program operation is complete, the system can once again
read array data within non-suspended blocks.
ERASE RESUME
When using the Automatic Sector Erase algorithm, note
that the erase automatically terminates when adequate
erase margin has been achieved for the memory array
(no erase verification command is required). Sector erase
is a six-bus cycle operation. There are two "unlock" write
cycles. These are followed by writing the set-up command 80H. Two more "unlock" write cycles are then followed by the sector erase command 30H. The sector
address is latched on the falling edge of WE# or CEx,
whichever happens later , while the command (data) is
latched on the rising edge of WE# or CEx, whichever
happens first. Sector addresses selected are loaded
into internal register on the sixth falling edge of WE# or
CEx, whichever happens later. Each successive sector
load cycle started by the falling edge of WE# or CEx,
whichever happens later must begin within 50us from
the rising edge of the preceding WE# or CEx, whichever
happens first. Otherwise, the loading period ends and
internal auto sector erase cycle starts. (Monitor Q3 to
determine if the sector erase timer window is still open,
see section Q3, Sector Erase Timer.) Any command other
than Sector Erase(30H) or Erase Suspend(B0H) during
the time-out period resets the device to read mode.
This command will cause the command register to clear
the suspend state and return back to Sector Erase mode
but only if an Erase Suspend command was previously
issued. Erase Resume will not have any effect in all
other conditions. Another Erase Suspend command can
be written after the chip has resumed erasing.
ERASE SUSPEND
This command only has meaning while the state machine is executing Automatic Sector Erase operation,
and therefore will only be responded during Automatic
Sector Erase operation. When the Erase Suspend command is issued during the sector erase operation, the

1. Q5 switches to "1" when an Word/Byte Program, Erase, or Write-to-Buffer operation has exceeded the maximum
timing limits. Refer to the section on Q5 for more information.
2. Q7 and Q2 require a valid address when reading status information. Refer to the appropriate subsection for further
details.
3. The Data# Polling algorithm should be used to monitor the last loaded write-buffer address location.

happens first pulse in the command sequence (prior to
the program or erase operation), and during the sector
time-out.
Q7: Data# Polling
The Data# Polling bit, Q7, indicates to the host system
whether an Automatic Algorithm is in progress or completed, or whether the device is in Erase Suspend. Data#
Polling is valid after the rising edge of the final WE# pulse
in the program or erase command sequence.
During an Automatic Program or Erase algorithm operation, successive read cycles to any address cause Q6
to toggle. The system may use either OE# or CEx to
control the read cycles. When the operation is complete,
Q6 stops toggling.
During the Automatic Program algorithm, the device outputs on Q7 the complement of the datum programmed
to Q7. This Q7 status also applies to programming during Erase Suspend. When the Automatic Program algorithm is complete, the device outputs the datum programmed to Q7. The system must provide the program
address to read valid status information on Q7. If a program address falls within a protected sector, Data# Polling on Q7 is active for approximately 1 us, then the device returns to reading array data.
After an erase command sequence is written, if all sectors selected for erasing are protected, Q6 toggles for
100us and returns to reading array data. If not all selected sectors are protected, the Automatic Erase algorithm erases the unprotected sectors, and ignores the
selected sectors that are protected.
The system can use Q6 and Q2 together to determine
whether a sector is actively erasing or is erase suspended.
When the device is actively erasing (that is, the Automatic Erase algorithm is in progress), Q6 toggling. When
the device enters the Erase Suspend mode, Q6 stops
toggling. However, the system must also use Q2 to determine which sectors are erasing or erase-suspended.
Alternatively, the system can use Q7.
During the Automatic Erase algorithm, Data# Polling produces a "0" on Q7. When the Automatic Erase algorithm
is complete, or if the device enters the Erase Suspend
mode, Data# Polling produces a "1" on Q7. This is analogous to the complement/true datum output described for
the Automatic Program algorithm: the erase function
changes all the bits in a sector to "1" prior to this, the
device outputs the "complement," or "0". The system must
provide an address within any of the sectors selected for
erasure to read valid status information on Q7.
If a program address falls within a protected sector, Q6
toggles for approximately 2us after the program command sequence is written, then returns to reading array
data.
After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling on
Q7 is active for approximately 100 us, then the device
returns to reading array data. If not all selected sectors
are protected, the Automatic Erase algorithm erases the
unprotected sectors, and ignores the selected sectors
that are protected.
Q6 also toggles during the erase-suspend-program mode,
and stops toggling once the Automatic Program algorithm is complete.
Table 5 shows the outputs for Toggle Bit I on Q6.
When the system detects Q7 has changed from the
complement to true data, it can read valid data at Q7-Q0
on the following read cycles. This is because Q7 may
change asynchronously with Q0-Q6 while Output Enable
(OE#) is asserted low.
Q2:Toggle Bit II
Q6:Toggle BIT I
The "Toggle Bit II" on Q2, when used with Q6, indicates
whether a particular sector is actively erasing (that is,
the Automatic Erase algorithm is in process), or whether
that sector is erase-suspended. Toggle Bit II is valid
after the rising edge of the final WE# or CEx, whichever
happens first pulse in the command sequence.
Toggle Bit I on Q6 indicates whether an Automatic Program or Erase algorithm is in progress or complete, or
whether the device has entered the Erase Suspend mode.
Toggle Bit I may be read at any address, and is valid
after the rising edge of the final WE# or CEx, whichever
Q2 toggles when the system reads at addresses within
those sectors that have been selected for erasure. (The
system may use either OE# or CEx to control the read
cycles.) But Q2 cannot distinguish whether the sector
is actively erasing or is erase-suspended. Q6, by com-

MX29LA129M H/L
If this time-out condition occurs during sector erase operation, it specifies that a particular sector is bad and it
may not be reused. However, other sectors are still functional and may be used for the program or erase operation. The device must be reset to use other sectors.
Write the Reset command sequence to the device, and
then execute program or erase command sequence. This
allows the system to continue to use the other active
sectors in the device.
parison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which
sectors are selected for erasure. Thus, both status bits
are required for sectors and mode information. Refer to
Table 5 to compare outputs for Q2 and Q6.
Reading Toggle Bits Q6/ Q2
Whenever the system initially begins reading toggle bit
status, it must read Q7-Q0 at least twice in a row to
determine whether a toggle bit is toggling. Typically, the
system would note and store the value of the toggle bit
after the first read. After the second read, the system
would compare the new value of the toggle bit with the
first. If the toggle bit is not toggling, the device has
completed the program or erase operation. The system
can read array data on Q7-Q0 on the following read cycle.
If this time-out condition occurs during the chip erase
operation, it specifies that the entire chip is bad or combination of sectors are bad.
If this time-out condition occurs during the byte/word programming operation, it specifies that the entire sector
containing that byte is bad and this sector may not be
reused, (other sectors are still functional and can be reused).
However, if after the initial two read cycles, the system
determines that the toggle bit is still toggling, the system also should note whether the value of Q5 is high
(see the section on Q5). If it is, the system should then
determine again whether the toggle bit is toggling, since
the toggle bit may have stopped toggling just as Q5 went
high. If the toggle bit is no longer toggling, the device
has successfully completed the program or erase operation. If it is still toggling, the device did not complete the
operation successfully, and the system must write the
reset command to return to reading array data.
The time-out condition may also appear if a user tries to
program a non blank location without erasing. In this
case the device locks out and never completes the Automatic Algorithm operation. Hence, the system never
reads a valid data on Q7 bit and Q6 never stops toggling.
Once the Device has exceeded timing limits, the Q5 bit
will indicate a "1". Please note that this is not a device
failure condition since the device was incorrectly used.
The Q5 failure condition may appear if the system tries
to program a to a "1" location that is previously programmed to "0". Only an erase operation can change a
"0" back to a "1". Under this condition, the device halts
the operation, and when the operation has exceeded the
timing limits, Q5 produces a "1".
The remaining scenario is that system initially determines
that the toggle bit is toggling and Q5 has not gone high.
The system may continue to monitor the toggle bit and
Q5 through successive read cycles, determining the status as described in the previous paragraph. Alternatively,
it may choose to perform other system tasks. In this
case, the system must start at the beginning of the algorithm when it returns to determine the status of the
operation.
Q3:Sector Erase Timer
After the completion of the initial sector erase command
sequence, the sector erase time-out will begin. Q3 will
remain low until the time-out is complete. Data# Polling
and Toggle Bit are valid after the initial sector erase command sequence.
Q5:Program/Erase Timing
Q5 will indicate if the program or erase time has exceeded
the specified limits (internal pulse count). Under these
conditions Q5 will produce a "1". This time-out condition
indicates that the program or erase cycle was not successfully completed. Data# Polling and Toggle Bit are
the only operating functions of the device under this condition.
If Data# Polling or the Toggle Bit indicates the device
has been written with a valid erase command, Q3 may
be used to determine if the sector erase timer window is
still open. If Q3 is high ("1") the internally controlled
erase cycle has begun; attempts to write subsequent
commands to the device will be ignored until the erase
operation is completed as indicated by Data# Polling or
P/N:PM1171
REV. 1.0, FEB. 27, 2006
31
MX29LA129M H/L
Toggle Bit. If Q3 is low ("0"), the device will accept additional sector erase commands. To insure the command
has been accepted, the system software should check
the status of Q3 prior to and following each subsequent
sector erase command. If Q3 were high on the second
status check, the command may not have been accepted.
If the time between additional erase commands from the
system can be less than 50us, the system need not to
monitor Q3.
Q1: Write-to-Buffer Abort
Q1 indicates whether a Write-to-Buffer operation was
aborted. Under these conditions Q1 produces a "1". The
system must issue the Write-to-Buffer-Abort-Reset command sequence to return the device to reading array data.
See Write Buffer section for more details.
RY/BY#:READY/BUSY OUTPUT
The RY/BY# is a dedicated, open-drain output pin that
indicates whether an Embedded Algorithm is in progress
or complete. The RY/BY# status is valid after the rising
edge of the final WE# pulse in the command sequence.
Since RY/BY# is an open-drain output, several RY/BY#
pins can be tied together in parallel with a pull-up resistor
to VCC .
If the output is low (Busy), the device is actively erasing
or programming. (This includes programming in the Erase
Suspend mode.) If the output is high (Ready), the device
is ready to read array data (including during the Erase
Suspend mode), or is in the standby mode.

Notes:
1. Not 100% tested.
2. See the "Erase And Programming Performance" section for more information.
3. For 1-16 words/1-32 bytes programmed.
4. Effective write buffer specification is based upon a 16-word/32-byte write buffer operation.
5. Word/Byte programming specification is based upon a single word/byte programming operation not utilizing the
write buffer.
6. When using the program suspend/resume feature, if the suspend command is issued within tPOLL, tPOLL must be
fully re-applied upon resuming the programming operation. If the suspend command is issued after tPOLL, tPOLL is
not required again prior to reading the status bits upon resuming.

Notes:
1. Typical program and erase times assume the following conditions: 25° C, 3.0V VCC. Programming specifications
assume checkboard data pattern.
2. Maximum values are measured at VCC = 3.0 V, worst case temperature. Maximum values are valid up to and
including 100,000 program/erase cycles.
3. Word/Byte programming specification is based upon a single word/byte programming operation not utilizing the
write buffer.
4. For 1-16 words or 1-32 bytes programmed in a single write buffer programming operation.
5. Effective write buffer specification is calculated on a per-word/per-byte basis for a 16-word/32-byte write buffer
operation.
6. In the pre-programming step of the Embedded Erase algorithm, all bits are programmed to 00h before erasure.
7. System-level overhead is the time required to execute the command sequence(s) for the program command. See
Tables 3 for further information on command definitions.
8. The device has a minimum erase and program cycle endurance of 100,000 cycles.
