GENERAL DESCRIPTION
The MX29F040C is a 4-mega bit Flash memory orga-
nized as 512K bytes of 8 bits. MXIC's Flash memories
offer the most cost-effective and reliable read/write non-
volatile random access memory. The MX29F040C is
packaged in 32-pin PLCC, TSOP, PDIP. It is designed
to be reprogrammed and erased in system or in standard
EPROM programmers.
erase and programming, while maintaining maximum
EPROM compatibility.
MXIC Flash technology reliably stores memory con-
tents even after 100,000 erase and program cycles.
The MXIC cell is designed to optimize the erase
and program mechanisms. In addition, the combi-
nation of advanced tunnel oxide processing and low
internal electric fields for erase and programming
operations produces reliable cycling. The
MX29F040C uses a 5.0V±10% VCC supply to per-
form the High Reliability Erase and auto Program/
Erase algorithms.
The standard MX29F040C offers access time as fast as
55ns, allowing operation of high-speed microprocessors
without wait states. To eliminate bus contention, the
MX29F040C 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
MX29F040C uses a command register to manage this
functionality. The command register allows for 100%TTL
level control inputs and fixed power supply levels during
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.

MX29F040C
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 sta-
tus of the programming operation.
AUTOMATIC PROGRAMMING
The MX29F040C is byte programmable using the Auto-
matic Programming algorithm. The Automatic Program-
ming algorithm makes the external system do not need
to have time out sequence nor to verify the data pro-
grammed. The typical chip programming time at room
temperature of the MX29F040C is less than 4.5 sec-
onds.
Register contents serve as inputs to an internal state-
machine which controls the erase and programming cir-
cuitry. During write cycles, the command register inter-
nally latches address and data needed for the program-
ming and erase operations. During a system write cycle,
addresses are latched on the falling edge of WE# or
CE#, whichever happens later, and data are latched on
the rising edge of WE# or CE#, whichever happens first.
AUTOMATIC CHIP ERASE
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 4 second. The Automatic Erase algorithm au-
tomatically programs the entire array prior to electrical
erase. The timing and verification of electrical erase are
controlled internally within the device.
MXIC's Flash technology combines years of EPROM
experience to produce the highest levels of quality, relia-
bility, and cost effectiveness. The MX29F040C electri-
cally erases all bits simultaneously using Fowler-Nord-
heim tunneling. The bytes are programmed by using the
EPROM programming mechanism of hot electron injec-
tion.
AUTOMATIC SECTOR ERASE
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 regis-
ter to respond to its full command set.
The MX29F040C 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 auto-
matically programs the specified sector(s) prior to
electrical erase. The timing and verification of electri-
cal erase are controlled internally within the device.
AUTOMATIC PROGRAMMING ALGORITHM
MXIC's Automatic Programming algorithm require the user
to only write program set-up commands (including 2 un-
lock write cycle and A0H) and a program command (pro-
gram data and address). The device automatically times
the programming pulse width, provides the program veri-
fication, and counts the number of sequences. A status
bit similar to Data# Polling and a status bit toggling be-
tween consecutive read cycles, provide feedback to the
user as to the status of the programming operation.
AUTOMATIC ERASE ALGORITHM
MXIC's Automatic Erase algorithm requires the user to
write commands to the command register using stand-
ard microprocessor write timings. The device will auto-
matically pre-program and verify the entire array. Then

COMMAND DEFINITIONS
Device operations are selected by writing specific address and data sequences into the command register. Writing
incorrect address and data values or writing them in the improper sequence will reset the device to the read mode.
Table 1 defines the valid register command sequences. Note that the Erase Suspend (B0H) and Erase Resume (30H)
commands are valid 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/SECTOR ERASE
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 de-
vice remains enabled for reads until the command regis-
ter 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.
The Automatic Chip Erase does not require the device to
be entirely pre-programmed prior to executing the Auto-
matic 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 verify begin. The
erase and verify operations are completed when the data
on Q7 is "1" at which time the device returns to the Read
mode. The system is not required to provide any control
or timing during these operations.
If program-fail or erase-fail happen, the write of F0H will
reset the device to abort the operation. A valid com-
mand must then be written to place the device in the
desired state.
SILICON-ID-READ COMMAND
Flash memories are intended for use in applications where
the local CPU alters memory contents. As such, manu-
facturer and device codes must be accessible while the
device resides in the target system. PROM program-
mers typically access signature codes by raising A9 to
a high voltage. However, multiplexing high voltage onto
address lines is not generally desired system design prac-
tice.
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 verification command is required).
If the Erase operation was unsuccessful, the data on Q5
is "1"(see Table 4), indicating the erase operation ex-
ceed internal timing limit.
The MX29F040C contains a Silicon-ID-Read operation
to supplement traditional PROM programming methodol-
ogy. The operation is initiated by writing the read silicon
ID command sequence into the command register. Fol-
lowing 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 A4H for MX29F040C.
The automatic erase begins on the rising edge of the last
WE# or CE#, whichever happens first pulse in the com-
mand sequence and terminates when the data on Q7 is
"1" and the data on Q6 stops toggling for two consecu-
tive read cycles, at which time the device returns to the
Read mode.

SECTOR ERASE COMMANDS
The Automatic Sector Erase does not require the device
to be entirely pre-programmed prior to executing the Au-
tomatic Set-up Sector Erase command and Automatic
Sector Erase command. Upon executing the Automatic
Sector Erase command, the device will automatically pro-
gram and verify the sector(s) memory for an all-zero data
pattern. The system is not required to provide any con-
trol or timing during these operations.
(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 com-
mand 80H. Two more "unlock" write cycles are then fol-
lowed by the sector erase command 30H. The sector
address is latched on the falling edge of WE# or CE#,
whichever happens later, while the command (data) is
latched on the rising edge of WE# or CE#, whichever
happens first. Sector addresses selected are loaded
into internal register on the sixth falling edge of WE# or
CE#, whichever happens later. Each successive sector
load cycle started by the falling edge of WE# or CE#,
whichever happens later must begin within 30us from
the rising edge of the precedingWE# or CE#, 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 EraseTimer.) Any command other
than Sector Erase (30H) or Erase Suspend (B0H) during
the time-out period resets the device to read mode.
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 op-
erations.
When using the Automatic Sector Erase algorithm, note
that the erase automatically terminates when adequate
erase margin has been achieved for the memory array

MX29F040C
Once the Automatic Program command is initiated, the
next WE# or CE# 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# or CE#, whichever happens first
pulse. The rising edge of WE# or CE#, whichever hap-
pens first also begins the programming operation. The
system is not required to provide further controls or tim-
ings. The device will automatically provide an adequate
internally generated program pulse and verify margin.
ERASE SUSPEND
This command only has meaning while the state ma-
chine is executing Automatic Sector Erase operation, and
therefore will only be responded during Automatic Sector
Erase operation. When the Erase Suspend command is
written during a sector erase operation, the device re-
quires a maximum of 20us to suspend the erase opera-
tions. However, When the Erase Suspend command is
written during the sector erase time-out, the device im-
mediately terminates the time-out period and suspends
the erase operation. After this command has been ex-
ecuted, the command register will initiate erase suspend
mode. The state machine will return to read mode auto-
matically after suspend is ready. At this time, state ma-
chine only allows the command register to respond to
the Read Memory Array, Erase Resume and program
commands.
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 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 pro-
gram operation is complete, the system can once again
read array data within non-suspended sectors.
DATA# POLLING-Q7
The MX29F040C also features Data# Polling as a method
to indicate to the host system that the Automatic Pro-
gram or Erase algorithms are either in progress or com-
pleted.
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.However,
a 400us time delay must be required after the erase re-
sume command, if the system implements an endless
erase suspend/resume loop, or the number of erase sus-
pend/resume is exceeded 1024 times.The erase times
will be expended if the erase behavior always be sus-
pended.
While the Automatic Programming algorithm is in opera-
tion, an attempt to read the device will produce the comple-
ment data of the data last written to Q7. Upon comple-
tion 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# or CE#, whichever happens first
pulse of the four write pulse sequences for automatic pro-
gram.
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 ris-
ing edge of the sixth WE# or CE#, whichever happens
first pulse of six write pulse sequences for automatic
chip/sector erase.
SET-UP AUTOMATIC PROGRAM COMMANDS
To initiate Automatic Program mode, A three-cycle com-
mand sequence is required. There are two "unlock" write
cycles. These are followed by writing the Automatic Pro-
gram command A0H.
The Data# Polling feature is active during Automatic Pro-
gram/Erase algorithm or sector erase time-out.(see sec-
tion Q3 Sector EraseTimer)

the rising edge of the final WE# or CE#, whichever hap-
pens first pulse in the command sequence.
Q6:Toggle BIT I
Toggle Bit I on Q6 indicates whether an Automatic Pro-
gram 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 CE#, whichever
happens first pulse in the command sequence (prior to
the program or erase operation), and during the sector
time-out.
Q2 toggles when the system reads at addresses within
those sectors that have been selected for erasure. (The
system may use either OE# or CE# to control the read
cycles.) But Q2 cannot distinguish whether the sector
is actively erasing or is erase-suspended. Q6, by com-
parison, indicates whether the device is actively eras-
ing, 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 4 to compare outputs for Q2 and Q6.
During an Automatic Program or Erase algorithm opera-
tion, successive read cycles to any address cause Q6
to toggle. The system may use either OE# or CE# to
control the read cycles.When the operation is complete,
Q6 stops toggling.
Reading Toggle Bits Q6/ Q2
After an erase command sequence is written, if all sec-
tors selected for erasing are protected, Q6 toggles 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.
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 com-
pleted the program or erase operation. The system can
read array data on Q7-Q0 on the following read cycle.
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 Auto-
matic 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 de-
termine which sectors are erasing or erase-suspended.
Alternatively, the system can use Q7.
However, if after the initial two read cycles, the system
determines that the toggle bit is still toggling, the sys-
tem 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 opera-
tion. 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.
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.
Q6 also toggles during the erase-suspend-program mode,
and stops toggling once the Automatic Program algorithm
is complete.
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 sta-
tus 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 al-
gorithm when it returns to determine the status of the
operation.
Table 4 shows the outputs for Toggle Bit I on Q6.
Q2:Toggle Bit II
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 I is valid after

several features to prevent inadvertent write cycles re-
sulting fromVCC power-up and power-down transition or
system noise.
Q5
Exceeded Timing Limits
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 suc-
cessfully completed. Data# Polling and Toggle Bit are
the only operating functions of the device under this con-
dition.
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
andToggle Bit are valid after the initial sector erase com-
mand sequence.
If this time-out condition occurs during sector erase op-
eration, it specifies that a particular sector is bad and it
may not be reused. However, other sectors are still func-
tional and may be used for the program or erase opera-
tion. 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 Data# Polling or theToggle 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 addi-
tional 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 the chip erase
operation, it specifies that the entire chip is bad or com-
bination of sectors are bad.
If this time-out condition occurs during the byte program-
ming operation, it specifies that the entire sector con-
taining that byte is bad and this sector may not be re-
used, (other sectors are still functional and can be re-
used).
WRITE PULSE "GLITCH" PROTECTION
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 Au-
tomatic 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.
Noise pulses of less than 5ns (typical) on CE# or WE#
will not initiate a write cycle.
LOGICAL INHIBIT
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.
DATA PROTECTION
The MX29F040C is designed to offer protection against
accidental erasure or programming caused by spurious
system level signals that may exist during power transi-
tion. 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 spe-
cific command sequences. The device also incorporates
POWER SUPPLY DECOUPLING
In order to reduce power switching effect, each device
should have a 0.1uF ceramic capacitor connected be-
tween itsVCC and GND.
