GENERAL DESCRIPTION
The MX29F001T/B is a 1-mega bit Flash memory
organized as 128K bytes of 8 bits only MXIC's
Flash memories offer the most cost-effective and
reliable read/write non-volatile random access
memory. The MX29F001T/B is packaged in 32-pin
PLCC, TSOP, PDIP. It is designed to be reprogrammed and erased in-system or in-standard
EPROM programmers.
programming, while maintaining maximum EPROM
compatibility.
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
programming mechanisms. In addition, the combination of advanced tunnel oxide processing and low
internal electric fields for erase and programming
operations produces reliable cycling.
The
MX29F001T/B uses a 5.0V ± 10% VCC supply to
perform the High Reliability Erase and auto
Program/Erase algorithms.
The standard MX29F001T/B offers access time
90ns. To eliminate bus contention, the MX29F001T/
B has separate chip enable (CE) and output enable
(OE) controls.
MXIC's Flash memories augment EPROM functionality with in-circuit electrical erasure and
programming. The MX29F001T/B uses a command
register to manage this functionality. The command
register allows for 100% TTL level control inputs
and fixed power supply levels during erase and
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
milliamps on address and data pin from -1V to VCC
+ 1V.

MX29F001T/B
AUTOMATIC PROGRAMMING
AUTOMATIC ERASE ALGORITHM
The MX29F001T/B is byte programmable using the Automatic Programming algorithm. The Automatic Programming algorithm does not require the system to time out
or verify the data programmed. The typical chip programming time of the MX29F001T/B at room temperature is less than 3.5 seconds.
AUTOMATIC CHIP ERASE
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 entire chip is bulk erased using 10 ms erase pulses
according to MXIC's Automatic Chip Erase algorithm.
Typical erasure at room temperature is accomplished in
less than 3 second. The Automatic Erase algorithm automatically programs the entire array prior to electrical
erase. The timing and verification of electrical erase are
internally controlled within the device.
Register contents serve as inputs to an internal statemachine which controls the erase and programming circuitry. During write cycles, the command register internally latches addresses 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 .
MXIC's Flash technology combines years of EPROM
experience to produce the highest levels of quality, reliability, and cost effectiveness. The MX29F001T/B electrically erases all bits simultaneously using FowlerNordheim tunneling. The bytes are programmed by using the EPROM programming mechanism of hot electron injection.
AUTOMATIC SECTOR ERASE
The MX29F001T/B 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 internally con trolled by the device.
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 PROGRAMMING ALGORITHM
MXIC's Automatic Programming algorithm requires the
user to only write program set-up commands (include 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, provides feedback to the user as to the status of the programming
operation.

only while the Sector Erase operation is in progress.
Either of the two reset command sequences will reset
the device(when applicable).

READ/RESET COMMAND
SET-UP AUTOMATIC CHIP ERASE COMMANDS
The read or reset operation is initiated by writing the read/
reset command sequence into the command register.
Microprocessor read cycles retrieve array data. The device remains enabled for reads until the command register contents are altered.
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.
If program-fail or erase-fail happen, the write of F0H will
reset the device to abort the operation. A valid command must then be written to place the device in the
desired state.
The Automatic Chip Erase does not require the device
to be entirely pre-programmed prior to executing the Automatic Chip Erase. Upon executing the Automatic Chip
Erase, the device will automatically program and verify
the entire memory for an all-zero data pattern. When the
device is automatically verified to contain an all-zero pattern, a self-timed chip erase and verification begin. The
erase and verification operations are completed when
the data on Q7 is "1" at which time the device returns to
the Read mode. The system does not require to provide any control or timing during these operations.
SILICON-ID-READ COMMAND
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 A9 to
a high voltage. However, multiplexing high voltage onto
address lines is not generally desired system design practice.
When using the Automatic Chip Erase algorithm, note
that the erase automatically terminates when adequate
erase margin has been achieved for the memory array(no
erase verify command is required).
The MX29F001T/B 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
A1=VIL,A0=VIL retrieves the manufacturer code of C2H.
A read cycle with A1=VIL, A0=VIH returns the device
code of 18H for MX29F001T,19H for MX29F001B.
If the Erase operation was unsuccessful, the data on Q5
is "1"(see Table 4), indicating an erase operation exceed
internal timing limit.
The automatic erase begins on the rising edge of the
last WE pulse in the command sequence and terminates
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.

SECTOR ERASE COMMANDS
ERASE SUSPEND
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 does not require to provide
any control or timing during these operations.
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. Writing the Erase Suspend command during the Sector Erase time-out immediately terminates the time-out immediately terminates the timeout 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 Read Memory Array, Erase
Resume and Program commands.
When the sector(s) is automatically verified to contain
an all-zero pattern, a self-timed sector erase and verification begin. The erase and verification 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
does not require 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 sectors.
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, while the
command(data) is latched on the rising edge of WE. Sector addresses selected are loaded into internal register
on the sixth falling edge of WE. Each successive sector
load cycle started by the falling edge of WE must begin
within 30us from the rising edge of the preceding WE.
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.

MX29F001T/B
WE pulse of the six write pulse sequences for chip/sector erase.
ERASE RESUME
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.
The Toggle Bit feature is active during Automatic Program/Erase algorithms or sector erase time-out. (see
section Q3 Sector Erase Timer)
DATA POLLING-Q7
The MX29F001T/B also features Data Polling as a
method to indicate to the host system that the Automatic Program or Erase algorithms are either in progress
or completed.
SET-UP AUTOMATIC PROGRAM COMMANDS
To initiate Automatic Program mode, A three-cycle command sequence is required. There are two "unlock" write
cycles. These are followed by writing the Automatic Program command A0H.
While the Automatic Programming algorithm is in operation, an attempt to read the device will produce the complement data of the data last written to Q7. Upon completion of the Automatic Program Algorithm an attempt to
read the device will produce the true data last written to
Q7. The Data Polling feature is valid after the rising edge
of the fourth WE pulse of the four write pulse sequences
for automatic program.
Once the Automatic Program command is initiated, the
next WE pulse causes a transition to an active programming operation. Addresses are latched on the falling
edge, and data are internally latched on the rising edge
of the WE pulse. The rising edge of WE also begins the
programming operation. The system does not require to
provide further controls or timings. The device will automatically provide an adequate internally generated program pulse and verify margin.
While the Automatic Erase algorithm is in operation, Q7
will read "0" until the erase operation is competed. Upon
completion of the erase operation, the data on Q7 will
read "1". The Data Polling feature is valid after the rising
edge of the sixth WE pulse of six write pulse sequences
for automatic chip/sector erase.
If the program operation was unsuccessful, the data on
Q5 is "1"(see Table 4), indicating the program operation
exceed internal timing limit. The automatic programming
operation is completed when the data read on Q6 stops
toggling for two consecutive read cycles and the data on
Q7 and Q6 are equivalent to data written to these two
bits, at which time the device returns to the Read mode
(no program verify command is required).
The Data Polling feature is active during Automatic Program/Erase algorithm or sector erase time-out.(see section Q3 Sector Erase Timer)
WRITE OPERATION STATUS
TOGGLE BIT-Q6
The MX29F001T/B features a "Toggle Bit" as a method
to indicate to the host system that the Auto Program/
Erase algorithms are either in progress or complete.
While the Automatic Program or Erase algorithm is in
progress, successive attempts to read data from the
device will result in Q6 toggling between one and zero.
Once the Automatic Program or Erase algorithm is completed, Q6 will stop toggling and valid data will be read.
The toggle bit is valid after the rising edge of the sixth

MX29F001T/B
Q5
Exceeded Timing Limits
Q3
Sector Erase Timer
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.
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.
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
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 this time-out condition occurs during sector erase operation, it is 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.
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.
DATA PROTECTION
If this time-out condition occurs during the byte 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).
The MX29F001T/B 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.
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.

MX29F001T/B
WRITE PULSE "GLITCH" PROTECTION
CHIP UNPROTECT WITH 12V SYSTEM
Noise pulses of less than 5ns(typical) on CE or WE will
not initiate a write cycle.
The MX29F001T/B also features the chip unprotect
mode, so that all sectors are unprotected after chip
unprotect completion to incorporate any changes in the
code.
LOGICAL INHIBIT
To activate this mode, the programming equipment must
force VID on control pin OE and address pin A9. The CE
pins must be set at VIL. Pins A6 must be set to VIH.(see
Table 2) Refer to chip unprotect algorithm and waveform for the chip unprotect algorithm. The unprotection
mechanism begins on the falling edge of the WE pulse
and is terminated with the rising edge of the same.
Writing is inhibited by holding any one of OE = VIL, CE =
VIH or WE = VIH. To initiate a write cycle CE and WE
must be a logical zero while OE is a logical one.
POWER SUPPLY DECOUPLING
It is also possible to determine if the chip is unprotected
in the system by writing the Read Silicon ID command.
Performing a read operation with A1=VIH, it will produce
00H at data outputs (Q0-Q7) for an unprotected sector. It
is noted that all sectors are unprotected after the chip
unprotect algorithm is completed.
In order to reduce power switching effect, each device
should have a 0.1uF ceramic capacitor connected between its VCC and GND. (Using a 10uF bulk capacitor
connected for high current condition is available if necessary.)
CHIP PROTECTION WITH 12V SYSTEM
CHIP PROTECTION WITHOUT 12V SYSTEM
The MX29F001T/B features hardware chip protection.
Which will disable both program and erase operations.
To activate this mode, the programming equipment must
force VID on address pin A9 and control pin OE, (suggest VID=12V) A6=VIL and CE=VIL.(see Table 2) Programming of the protection circuitry begins on the falling
edge of the WE pulse and is terminated with the rising
edge of the same. Please refer to chip protect algorithm
and waveform.
The MX29F001T/B also feature a hardware chip protection method in a system without 12V power supply. The
programming equipment do not need to supply 12 volts
to protect all sectors. The details are shown in chip protect algorithm and waveform.
CHIP UNPROTECT WITHOUT 12V SYSTEM
The MX29F001T/B also feature a hardware chip
unprotection method in a system without 12V power supply. The programming equipment do not need to supply
12 volts to unprotect all sectors. The details are shown
in chip unprotect algorithm and waveform.
To verify programming of the protection circuitry, the programming equipment must force VID on address pin A9
( with CE and OE at VIL and WE at VIH. When A1=1, it
will produce a logical "1" code at device output Q0 for
the protected status. Otherwise the device will produce
00H for the unprotected status. In this mode, the address, except for A1, are don't care. Address locations
with A1 = VIL are reserved to read manufacturer and
device codes.(Read Silicon ID)
POWER-UP SEQUENCE
The MX29F001T/B powers up in the Read only mode. In
addition, the memory contents may only be altered after
successful completion of the predefined command sequences.
It is also possible to determine if the chip is protected in
the system by writing a Read Silicon ID command. Performing a read operation with A1=VIH, it will produce a
logical "1" at Q0 for the protected status.
