GENERAL DESCRIPTION
The MX29F1611 is a 16-mega bit Pagemode Flash
memory organized as either 1M wordx16 or 2M bytex8.
The MX29F1611 includes 16-128KB(131,072 Bytes)
blocks or 16-64KW(65,536 Words)blocks. MXIC's Flash
memories offer the most cost-effective and reliable read/
write non-volatile random access memory and fast page
mode access. The MX29F1611 is packaged 44-pin
SOP. It is designed to be reprogrammed and erased insystem or in-standard EPROM programmers.
To allow for simple in-system reprogrammability, the
MX29F1611 does not require high input voltages for
programming. Five-volt-only commands determine the
operation of the device. Reading data out of the device
is similar to reading from an EPROM.
MXIC Flash technology reliably stores memory contents
even after 10,000 cycles. The MXIC's 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
MX29F1611 uses a 5V ± 5% VCC supply to perform the
Auto Erase and Auto Program algorithms.
The standard MX29F1611 offers access times as fast as
100ns,allowing operation of high-speed microprocessors
without wait. To eliminate bus contention, the
MX29F1611 has separate chip enable CE, output enable
(OE), and write enable (WE) controls.
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.
MXIC's Flash memories augment EPROM functionality
with in-circuit electrical erasure and programming. The
MX29F1611 uses a command register to manage this
functionality.

WRITE OPERATIONS
will only respond to status reads. During a sector/chip
erase cycle, the CIR will respond to status reads and
erase suspend. After the write state machine has
completed its task, it will allow the CIR to respond to its full
command set. The CIR stays at read status register
mode until the microprocessor issues another valid
command sequence.
Commands are written to the COMMAND INTERFACE
REGISTER (CIR) using standard microprocessor write
timings. The CIR serves as the interface between the
microprocessor and the internal chip operation. The CIR
can decipher Read Array, Read Silicon ID, Erase and
Program command. In the event of a read command, the
CIR simply points the read path at either the array or the
silicon ID, depending on the specific read command
given. For a program or erase cycle, the CIR informs the
write state machine that a program or erase has been
requested. During a program cycle, the write state
machine will control the program sequences and the CIR
Device operations are selected by writing commands into
the CIR. Table 3 below defines 16 Mbit flash family

DEVICE OPERATION
SILICON ID READ
The Silicon ID Read mode allows the reading out of a
binary code from the device and will identify its
manufacturer and type. This mode is intended for use by
programming equipment for the purpose of automatically
matching the device to be programmed with its
corresponding programming algorithm. This mode is
functional over the entire temperature range of the
device.
MX29F1611 is erased or programmed in a system
without access to high voltage on the A9 pin. The
command sequence is illustrated in Table 3.
To activate this mode, the programming equipment must
force VID (11.5V~12.5V) on address pin A9. Two
identifier bytes may then be sequenced from the device
outputs by toggling address A0 from VIL to VIH. All
addresses are don't cares except A0 and A1.
To terminate the operation, it is necessary to write the
read/reset command sequence into the CIR.
Byte 0 (A0=VIL) represents the manfacturer's code
(MXIC=C2H) and byte 1 (A0=VIH) the device identifier
code (MX29F1611=F7H).
The manufacturer and device codes may also be read via
the command register, for instances when the

MX29F1611
Any attempt to write to the device without the three-cycle
command sequence will not start the internal Write State
Machine(WSM), no data will be written to the device.
READ/RESET COMMAND
The read or reset operation is initiated by writing the read/
reset command sequence into the command register.
Microprocessor read cycles retrieve array data from the
memory. The device remains enabled for reads until the
CIR contents are altered by a valid command sequence.
After three-cycle command sequence is given, a
byte(word) load is performed by applying a low pulse on
the WE or CE input with CE or WE low (respectively) and
OE high. The address is latched on the falling edge of CE
or WE, whichever occurs last. The data is latched by the
first rising edge of CE or WE. Maximum of 128 bytes of
data may be loaded into each page by the same
procedure as outlined in the page program section below.
The device will automatically power-up in the read/reset
state. In this case, a command sequence is not required
to read data. Standard microprocessor read cycles will
retrieve array data. This default value ensures that no
spurious alteration of the memory content occurs during
the power transition. Refer to the AC Read
Characteristics and Waveforms for the specific timing
parameters.
BYTE-WIDE LOAD/WORD-WIDE LOAD
Byte(word) loads are used to enter the 128 bytes(64
words) of a page to be programmed or the software codes
for data protection. A byte load(word load) is performed
by applying a low pulse on the WE or CE input with CE or
WE low (respectively) and OE high. The address is
latched on the falling edge of CE or WE, whichever occurs
last. The data is latched by the first rising edge of CE or
WE.
The MX29F1611 is accessed like an EPROM. When CE
and OE are low and WE is high the data stored at the
memory location determined by the address pins is
asserted on the outputs. The outputs are put in the high
impedance state whenever CE or OE is high. This dual
line control gives designers flexibility in preventing bus
contention.
Note that the read/reset command is not valid when
program or erase is in progress.
Either byte-wide load or word-wide load is
determined(Byte = VIL or VIH is latched) on the falling
edge of the WE(or CE) during the 3rd command write
cycle.
PAGE READ
PROGRAM
The MX29F1611 offers fast page mode read feature. The
users can take the access time advantage if keeping CE,
OE at low and the same page address (A3~A19
unchanged). Please refer to Figure 5-2 for detailed timing
waveform. The system performance could be enhanced
by initiating 1 normal read and 7 fast page reads(for word
mode A0~A2) or 15 fast page reads(for byte mode
altering A-1~A2).
Any page to be programmed should have the page in the
erased state first, i.e. performing sector erase is
suggested before page programming can be performed.
The device is programmed on a page basis. If a
byte(word) of data within a page is to be changed, data for
the entire page can be loaded into the device. Any
byte(word) that is not loaded during the programming of
its page will be still in the erased state (i.e. FFH). Once
the bytes of a page are loaded into the device, they are
simultaneously programmed during the internal
programming period. After the first data byte(word) has
been loaded into the device, successive bytes(words)
are entered in the same manner. Each new byte(word)
to be programmed must have its high to low transition on
WE (or CE) within 30us of the low to high transition of WE
(or CE) of the preceding byte(word). A6 to A19 specify
the page address, i.e., the device is page-aligned on 128
PAGE PROGRAM
To initiate Page program mode, a three-cycle command
sequence is required. There are two " unlock" write
cycles. These are followed by writing the page program
command-A0H.

bytes(64 words)boundary. The page address must be
valid during each high to low transition of WE or CE. A-1
to A5 specify the byte address within the page, A0 to A5
specify the word address withih the page. The byte(word)
may be loaded in any order; sequential loading is not
required. If a high to low transition of CE or WE is not
detected whithin 100us of the last low to high transition,
the load period will end and the internal programming
period will start. The Auto page program terminates when
status on DQ7 is '1' at which time the device stays at read
status register mode until the CIR contents are altered by
a valid command sequence.(Refer to table 3,6 and Figure
1,7,8)
SECTOR ERASE
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 erase does not require the user to program the
device prior to erase. The system is not required to
provide any controls or timings during these operations.
The automatic sector erase begins on the rising edge of
the last WE pulse in the command sequence and
terminates when the status on DQ7 is "1" at which time
the device stays at read status register mode. The device
remains enabled for read status register mode until the
CIR contents are altered by a valid command
sequence.(Refer to table 3,6 and Figure 3,4,7,9))
CHIP 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.
Chip erase does not require the user to program the
device prior to erase.
ERASE SUSPEND
This command only has meaning while the the WSM is
executing SECTOR or CHIP erase operation, and
therefore will only be responded to during SECTOR or
CHIP erase operation. After this command has been
executed, the CIR will initiate the WSM to suspend erase
operations, and then return to Read Status Register
mode. The WSM will set the DQ6 bit to a "1". Once the
WSM has reached the Suspend state,the WSM will set
the DQ7 bit to a "1", At this time, WSM allows the CIR to
respond to the Read Array, Read Status Register, Abort
and Erase Resume commands only. In this mode, the
CIR will not resopnd to any other comands. The WSM will
continue to run, idling in the SUSPEND state, regardless
of the state of all input control pins.
The automatic erase begins on the rising edge of the last
WE pulse in the command sequence and terminates
when the status on DQ7 is "1" at which time the device
stays at read status register mode. The device remains
enabled for read status register mode until the CIR
contents are altered by a valid command
sequence.(Refer to table 3,6 and Figure 2,7,9)

completed successfully. The status register may be read
at any time by writing the Read Status command to the
CIR. After writing this command, all subsequent read
operations output data from the status register until
another valid command sequence is written to the CIR. A
Read Array command must be written to the CIR to return
to the Read Array mode.
The Eraes fail status bit (DQ5) and Program fail status bit
(DQ4) are set by the write state machine, and can only be
reset by the system software. These bits can indicate
various failure conditions(see Table 6). By allowing the
system software to control the resetting of these bits,
several operations may be performed (such as
cumulatively programming several pages or erasing
multiple blocks in squence). The status register may then
be read to determine if an error occurred during that
programming or erasure series. This adds flexibility to the
way the device may be programmed or erased.
Additionally, once the program(erase) fail bit happens,
the program (erase) operation can not be performed
further. The program(erase) fail bit must be reset by
system software before further page program or sector
(chip) erase are attempted. To clear the status register,
the Clear Status Register command is written to the CIR.
Then, any other command may be issued to the CIR.
Note again that before a read cycle can be initiated, a
Read command must be written to the CIR to specify
whether the read data is to come from the Array, Status
Register or Silicon ID.
The status register bits are output on DQ2 - DQ7(table 6)
whether the device is in the byte-wide (x8) or word-wide
(x16) mode for the MX29F1611. In the word-wide mode
the upper byte, DQ(8:15) is set to 00H during a Read
Status command. In the byte-wide mode, DQ(8:14) are
tri-stated and DQ15/A-1 retains the low order address
function. DQ0-DQ1 is set to 0H in either x8 or x16 mode.
It should be noted that the contents of the status register
are latched on the falling edge of OE or CE whichever
occurs last in the read cycle. This prevents possible bus
errors which might occur if the contents of the status
register change while reading the status register. CE or
OE must be toggled with each subsequent status read, or
the completion of a program or erase operation will not be
evident.
The Status Register is the interface between the
microprocessor and the Write State Machine (WSM).
When the WSM is active, this register will indicate the
status of the WSM, and will also hold the bits indicating
whether or not the WSM was successful in performing the
desired operation. The WSM sets status bits four through
seven and clears bits six and seven, but cannot clear
status bits four and five. If Erase fail or Program fail status
bit is detected, the Status Register is not cleared until the
Clear Status Register command is written. The
MX29F1611 automatically outputs Status Register data
when read after Chip Erase, Sector Erase, Page Program
or Read Status Command write cycle. The default state
of the Status Register after powerup and return from deep
power-down mode is (DQ7, DQ6, DQ5, DQ4) = 1000B.
DQ3 = 0 or 1 depends on sector-protect status, can not be
changed by Clear Status Register Command or Write
State Machine. DQ2 = 0 or 1 depends on Sleep status,
During Sleep mode or Abort mode DQ2 is set to "1"; DQ2
is reset to "0" by Read Array command.

five write command cycles in activating sector protection
mode followed by the Unprotect Sector command - 40H,
the automatic Unprotect operation begins on the rising
edge of the last WE pulse in the command sequence and
terminates when the Status on DQ7 is '1' at which time the
device stays at the read status register mode.(Refer to
table 3,6 and Figure 11,12)
HARDWARE SECTOR PROTECTION
The MX29F1611 features sector protection. This feature
will disable both program and erase operations in either
the top or the bottom sector (0 or 15). The sector
protection feature is enabled using system software by
the user(Refer to table 3). The device is shipped with
both sectors unprotected. Alternatively, MXIC may
protect sectors in the factory prior to shipping the device.
The device remains enabled for read status register
mode until the CIR contents are altered by a valid
command sequence.
SECTOR PROTECTION
Either Protect or Unprotect sector mode is accomplished
by keeping WP high, i.e. protect-bit status can only be
changed with a valid command sequence and WP at high.
When WP is high, all sectors can be programmed or
erased regardless of the state of the protect-bits. Protectbit status will not be changed during chip/sector erase
operations. With WP at VIL, only unprotected sectors
can be programmed or erased.
To activate this mode, a six-bus cycle operation is
required. There are two 'unlock' write cycles. These are
followed by writing the 'set-up' command. Two more
'unlock' write cycles are then followed by the Lock Sector
command - 20H. Sector address is latched on the falling
edge of CE or WE of the sixth cycle of the command
sequence. The automatic Lock operation begins on the
rising edge of the last WE pulse in the command
sequence and terminates when the Status on DQ7 is '1'
at which time the device stays at the read status register
mode.
SLEEP MODE
The MX29F1611 features two software controlled lowpower modes : Sleep and Abort modes. Sleep mode is
allowed during any current operations except that once
Suspend command is issued, Sleep command is ignored.
Abort mode is excuted only during Page Program and
Chip/Sector Erase mode.
The device remains enabled for read status register
mode until the CIR contents are altered by a valid
command sequence (Refer to table 3,6 and Figure 10,12
).
To activate Sleep mode, a three-bus cycle operation is
required. The C0H command (Refer to table 3) puts the
device in the Sleep mode. Once in the Sleep mode and
with CMOS input level applied, the current of the device
is 100uA.
VERIFY SECTOR PROTECT
To verify the Protect status of the Top and the Bottom
sector, operation is initiated by writing Silicon ID read
command into the command register. Following the
command write, a read cycle from address XXX0H
retrieves the Manufacturer code of C2H. A read cycle
from XXX1H returns the Device code F7H. A read cycle
from appropriate address returns information as to which
sectors are protected. To terminate the operation, it is
necessary to write the read/reset command sequence
into the CIR.
(Refer to table 3,4 and Figure 12)
The Sleep command allows the device to COMPLETE
current operations before going into Sleep mode. Once
current operation is done, device stays at read status
register mode. The status registers are not reset during
sleep command. Program or erase fail bit may have been
set if during program/erase mode the device retry
exceeds maximum count.
During Sleep mode, the status registers, Silicon ID codes
remain valid and can still be read. The Device Sleep
Status bit - DQ2 will indicate that the device in the sleep
mode.
A few retries are required if Protect status can not be
verified successfully after each operation.
SECTOR UNPROTECT
Writing the Read Array command wakes up the device
out of sleep mode. DQ2 is reset to "0" and Device returns
to standby current level.
It is also possible to unprotect the sector , same as the first

INDEX
MX29F1611
ABORT MODE
LOW VCC WRITE INHIBIT
To activate Abort mode, a three-bus cycle operation is
required. The E0H command (Refer to table 3) only stops
Page program or Sector /Chip erase operation currently
in progress and puts the device in Sleep mode. But unlike
the sleep command, the program or erase operation will
not be completed. Since the data in some page/sectors
is no longer valid due to an incomplete program or erase
operation, the program fail (DQ4) or erase fail (DQ5)bit
will be set.
To avoid initiation of a write cycle during VCC power-up
and power-down, a write cycle is locked out for VCC less
than VLKO(= 3.2V , typically 3.5V). If VCC < VLKO, the
command register is disabled and all internal program/
erase circuits are disabled. Under this condition the
device will reset to the read mode. Subsequent writes will
be ignored until the VCC level is greater than VLKO. It is
the user's responsibility to ensure that the control pins are
logically correct to prevent unintentional write when VCC
is above VLKO.
After the abort command is executed and with CMOS
input level applied, the device current is reduced to the
same level as in sleep modes.
WRITE PULSE "GLITCH" PROTECTION
During Abort mode, the status registers, Silicon ID codes
remain valid and can still be read. The Device Sleep
Status bit - DQ2 will indicate that the device in the sleep
mode.
Noise pulses of less than 10ns (typical) on CE or WE will
not initiate a write cycle.
Similar to the sleep mode, A read array command MUST
be written to bring the device out of the abort state without
incurring any wake up latency. Note that once device is
waken up, Clear status register mode is required before
a program or erase operation can be executed.
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 MX29F1611 is designed to offer protection against
accidental erasure or programming caused by spurious
system level signals that may exist during power
transitions. During power up the device automatically
resets the internal state machine in the Read Array mode.
Also, with its control register architecture, alteration of the
memory contents only occurs after successful
completion of specific multi-bus cycle command
sequences.
The device also incorporates several features to prevent
inadvertent write cycles resulting from VCC power-up
and power-down transitions or system noise.
