GENERAL DESCRIPTION
To allow for simple in-system reprogrammability, the
MX29L1611 does not require high input voltages for
programming. Three-volt-only commands determine
the operation of the device. Reading data out of the
device is similar to reading from an EPROM.
The MX29L1611 is a 16-mega bit pagemode Flash
memory organized as either 1M wordx16 or 2M bytex8.
The MX29L1611 includes 32 sectors of 64KB(65,536
Bytes or 32,768 words). MXIC's Flash memories offer
the most cost-effective and reliable read/write nonvolatile random access memory and fast page mode
access. The MX29L1611 is packaged 44-pin SOP and
48-TSOP(I). It is designed to be reprogrammed and
erased in-system or in-standard EPROM programmers.
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
MX29L1611 uses a 2.7V~3.6V VCC supply to perform
the Auto Erase and Auto Program algorithms.
The standard MX29L1611 offers access times as fast as
100ns,allowing operation of high-speed microprocessors
without wait. To eliminate bus contention, the MX29L1611
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
MX29L1611 uses a command register to manage this
functionality.

NAME AND FUNCTION
ADDRESS INPUTS: for memory addresses. Addresses are internally
latched during a write cycle.
LOW-BYTE DATA BUS: Input data and commands during Command Interface
Register(CIR) write cycles. Outputs array,status and identifier data in the
appropriate read mode. Floated when the chip is de-selected or the outputs
are disabled.
HIGH-BYTE DATA BUS: Inputs data during x 16 Data-Write operations.
Outputs array, identifier data in the appropriate read mode; not used for status
register reads. Floated when the chip is de-selected or the outputs are
disabled
Selects between high-byte data INPUT/OUTPUT(BYTE = HIGH) and LSB
ADDRESS(BYTE = LOW)
CHIP ENABLE INPUTS: Activate the device's control logic, Input buffers,
decoders and sense amplifiers. With CE high, the device is deselected and
power consumption reduces to Standby level upon completion of any current
program or erase operations. CE must be low to select the device.
OUTPUT ENABLES: Gates the device's data through the output buffers
during a read cycle OE is active low.
WRITE ENABLE: Controls writes to the Command Interface Register(CIR).
WE is active low.
WRITE PROTECT: Top or Bottom sector can be protected by writing a nonvolatile protect-bit for each sector. When WP is high, all sectors can be
programmed or erased regardless of the state of the protect-bits.
BYTE ENABLE: BYTE Low places device in x8 mode. All data is then input
or output on Q0-7 and Q8-14 float. AddressQ15/A-1 selects between the high
and low byte. BYTE high places the device in x16 mode, and turns off the Q15/
A-1 input buffer. Address A0, then becomes the lowest order address.

MX29L1611
WRITE OPERATIONS
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 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.
Device operations are selected by writing commands
into the CIR. Table 3 below defines 16 Mbit flash family
command.

DEVICE OPERATION
SILICON ID READ
The manufacturer and device codes may also be read
via the command register, for instances when the
MX29L1611 is erased or programmed in a system
without access to high voltage on the A9 pin. The
command sequence is illustrated in Table 3.
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.
Byte 0 (A0=VIL) represents the manfacturer's code
(MXIC=C2H) and byte 1 (A0=VIH) the device identifier
code (MX29L1611=F8H).
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.

MX29L1611
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.
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.
The device will automatically power-up in the read/reset
state. In this case, a command sequence is not required
for "read operation". 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 MX29L1611 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.
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.
Note that the read/reset command is not valid when
program or erase is in progress.
PROGRAM
PAGE READ
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 MX29L1611 offers "fast page mode read" function.
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).
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
bytes(64 words)boundary. The page address must be
valid during each high to low transition of WE or CE. A1 to A5 specify the byte address within the page, A0 to
A5 specify the word address withih the page. The
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.
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.
P/N:PM0511
REV. 2.4, NOV. 06, 2001

MX29L1611
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
CHIP ERASE
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.
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.
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 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 does not require the user to program the
device prior to erase.
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)
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

MX29L1611
READ STATUS REGISTER
CLEAR STATUS REGISTER
The MXIC's 16 Mbit flash family contains a status
register which may be read to determine when a program
or erase operation is complete, and whether that
operation 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 DQ3 - DQ7(table
6) whether the device is in the byte-wide (x8) or wordwide (x16) mode for the MX29L1611. 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.
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
MX29L1611 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.

MX29L1611
HARDWARE SECTOR PROTECTION
SECTOR UNPROTECT
The MX29L1611 features sector protection. This feature
will disable both program and erase operations in either
the top or the bottom sector (0 or 31). 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.
It is also possible to unprotect the sector , same as the
first 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)
SECTOR PROTECTION
The device remains enabled for read status register
mode until the CIR contents are altered by a valid
command sequence.
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.
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.
Protect-bit status will not be changed during chip/sector
erase operations. With WP at VIL, only unprotected
sectors can be programmed or erased.
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 ).
ABORT MODE
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 Abort mode.
So 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.
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 F8H. 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.
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 brought out, Clear
status register mode is required before a program or
erase operation can be executed.
(Refer to table 3,4 and Figure 12)
A few retries are required if Protect status can not be
verified successfully after each operation.

MX29L1611
DATA PROTECTION
The MX29L1611 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.
LOW VCC WRITE INHIBIT
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(typically 1.8V). 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.
WRITE PULSE "GLITCH" PROTECTION
Noise pulses of less than 10ns (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.
