M29FxxxFT/B
General Description
General Description
This description applies specifically to the M29F 16Mb (2 Meg x 8 or 1 Meg x 16) nonvolatile memory device, but also applies to lower densities. The device enables READ,
ERASE, and PROGRAM operations using a single, low-voltage (4.5–5.5V) supply. On
power-up, the device defaults to read mode and can be read in the same way as a ROM
or EPROM.
The device is divided into blocks that can be erased independently, preserving valid data while old data is erased. Each block can be protected independently to prevent accidental PROGRAM or ERASE operations from modifying the memory. PROGRAM and
ERASE commands are written to the command interface. An on-chip program/erase
controller simplifies the process of programming or erasing the device by managing the
operations required to update the memory contents.
The end of a PROGRAM or ERASE operation can be detected and any error conditions
identified. The command set required to control the memory is consistent with JEDEC
standards.
The blocks are asymmetrically arranged. The first or last 64KB have been divided into
four additional blocks. The 16KB boot block can be used for small initialization code to
start the microprocessor. The two 8KB parameter blocks can be used for parameter
storage. The remaining 32KB is a small main block where the application may be stored.
CE#, OE#, and WE# control the bus operation of the memory. They enable simple connection to most microprocessors, often without additional logic. Devices are offered in
48-pin TSOP (12mm x 20mm) and 44-pin small-outline packages. The device is supplied with all the bits erased (set to 1).

Signal Descriptions
Signal Descriptions
The signal description table below is a comprehensive list of signals for this device family. All signals listed may not be supported on this device. See Signal Assignments for information specific to this device.
Table 2: Signal Descriptions
Name
Type
Description
A[MAX:0]
Input
Address: Selects the cells in the array to access during READ operations. During WRITE operations, they control the commands sent to the command interface of the program/erase controller.
CE#
Input
Chip enable: Activates the device, enabling READ and WRITE operations to be performed.
When CE# is HIGH, all other pins are ignored.
OE#
Input
Output enable: Controls the bus READ operation.
WE#
Input
Write enable: Controls the bus WRITE operation of the command interface.
BYTE#
Input
Byte/word organization select: Switches between x8 and x16 bus modes. When BYTE# is
LOW, the device is in x8 mode; when HIGH, the device is in x16 mode.
RST#
Input
Reset: Applies a hardware reset to the device, which is achieved by holding RST# LOW for at
least tPLPX. After RST# goes HIGH, the device is ready for READ and WRITE operations (after
tPHEL or tRHEL, whichever occurs last).
Holding RST# at VID will temporarily unprotect the protected blocks. PROGRAM and ERASE
operations on all blocks will then be possible. The transition from VIH to VID must be slower
than tPHPHH.
DQ[7:0]
I/O
Data I/O: Outputs the data stored at the selected address during a READ operation. During
WRITE operations, they represent the commands sent to the command interface of the program/erase controller.
DQ[14:8]
I/O
Data I/O: Outputs the data stored at the selected address during a READ operation when
BYTE# is HIGH. When BYTE# is LOW, these pins are not used and are High-Z. During WRITE
operations, these bits are not used. When reading the status register, these bits should be ignored.
DQ15/A-1
I/O
Data I/O or address input: When the device operates in x16 bus mode, this pin behaves as
data I/O, together with DQ[14:8]. When the device operates in x8 bus mode, this pin behaves
as the least significant bit of the address.
Except where stated explicitly otherwise, DQ15 = data I/O (x16 mode); A-1 = address input (x8
mode).
RY/BY#
Output
Ready busy: Open-drain output that can be used to identify when the device is performing
a PROGRAM or ERASE operation. During PROGRAM or ERASE operations, RY/BY# is LOW,
and is High-Z during read mode, auto select mode, and erase suspend mode. After a hardware reset, READ and WRITE operations cannot begin until RY/BY# goes High-Z (see RESET
AC Specifications for more details).
The use of an open-drain output enables the RY/BY# pins from several devices to be connected to a single pull-up resistor to VCCQ. A low value will then indicate that one (or more) of
the devices is (are) busy.

Signal Descriptions
Table 2: Signal Descriptions (Continued)
Name
Type
VCC
Supply
Supply voltage: Provides the power supply for READ, PROGRAM, and ERASE operations.
The command interface is disabled when VCC < VLKO. This prevents WRITE operations from
accidentally damaging the data during power-up, power-down, and power surges. If the program/erase controller is programming or erasing during this time, then the operation aborts
and the contents being altered will be invalid.
A 0.1μF capacitor should be connected between VCC and VSS to decouple the current surges
from the power supply. The PCB track widths must be sufficient to carry the currents required
during PROGRAM and ERASE operations (see DC Characteristics).
VSS
Supply
Ground: Reference for all voltage measurements. All VSS pins must be connected to the system ground.

1. H = Logic level HIGH (VIH); L = Logic level LOW (VIL); X = HIGH or LOW.
2. Typically glitches of less than 5ns on Chip Enable or Write Enable are ignored by the
memory and do not affect bus operations.
Notes:
Read
Bus READ operations read from the memory cells or specific registers in the command
interface. A valid bus READ operation involves setting the desired address on the address inputs, taking CE# and OE# LOW, and holding WE# HIGH. The data I/Os will output the value. (See AC Characteristics for details about when the output becomes valid.)
Write
Bus WRITE operations write to the command interface. A valid bus WRITE operation
begins by setting the desired address on the address inputs. The address inputs are
latched by the command interface on the falling edge of CE# or WE#, whichever occurs
last. The data I/Os are latched by the command interface on the rising edge of CE# or
WE#, whichever occurs first. OE# must remain HIGH during the entire bus WRITE operation. (See AC Characteristics for timing requirement details.)
Output Disable
Data I/Os are High-Z when OE# is HIGH.
Standby
When CE# is HIGH, the device enters standby, and data I/Os are High-Z. To reduce the
supply current to the standby supply current (ICC2), CE# must be held within V CC ±0.2V.
(See DC Characteristics.) During PROGRAM or ERASE operations the device will continue to use the program/erase supply current (ICC3) until the operation completes.
Automatic Standby
If CMOS levels (VCC ±0.2V) are used to drive the bus, and the bus is inactive for 150ns or
more, the device enters automatic standby, and the internal supply current is reduced
to that of the standby supply current, ICC2. The data I/Os will output data if a READ operation is in progress.

Command Interface
Command Interface
All WRITE operations are interpreted by the command interface. Commands consist of
one or more sequential WRITE operations. Failure to observe a valid sequence will result in the memory returning to read mode. The long command sequences are imposed
to maximize data security.
The address used for the commands changes depending on whether the memory is in
16-bit or 8-bit mode.
READ/RESET Command
The READ/RESET command returns the device to read mode, where it behaves like a
ROM or EPROM, unless otherwise stated. It also resets the errors in the status register.
Either one or three WRITE operations can be used to issue the READ/RESET command.
The READ/RESET command can be issued, between WRITE cycles, before the start of a
PROGRAM or ERASE operation, to return the device to read mode. Once the PROGRAM
or ERASE operation has started, the READ/RESET command is no longer accepted. The
READ/RESET command will not abort an ERASE operation when issued while in erase
suspend.
AUTO SELECT Command
The AUTO SELECT command is used to read the electronic signature, including the
manufacturer code, the device code and the block protection status. Three consecutive
WRITE operations are required to issue the AUTO SELECT command. Once the command is issued, the memory remains in auto select mode until a READ/RESET command is issued. READ CFI QUERY and READ/RESET commands are accepted in auto
Select mode, while all other commands are ignored.
Note: These operations are intended for use by programming equipment and are not
typically used in applications. They require V ID to be applied to some of the pins.
From the auto select mode the manufacturer code can be read using a READ operation
with A0 = V IL and A1 = V IL. The other address bits may be set to either V IL or V IH. The
manufacturer code for Micron is 0001h.
The device code can be read using a READ operation with A0 = V IH and A1 = V IL. The
other address bits may be set to either V IL or V IH.
The block protection status of each block can be read using a READ operation with A0 =
VIL, A1 = V IH, and A12-A19 specifying the address of the block. The other address bits
may be set to either V IL or V IH. If the addressed block is protected then 01h is output on
Data Inputs/Outputs DQ0-DQ7, otherwise 00h is output. See Block Protection Operations for information on the block protection status; the Programmer Technique Block
Protection table includes block protection bus READ information.

Note:
PROGRAM Command
The PROGRAM command can be used to program a value to one address at a time. The
command requires four bus WRITE operations. The final WRITE operation latches the
address and data, and starts the program/erase controller.
If the address falls in a protected block, then the PROGRAM command is ignored, the
data remains unchanged. The status register is never read and no error condition is given.
During the PROGRAM operation, the memory will ignore all commands. It is not possible to issue any command to abort or pause the operation. Typical program times are
given in READ CFI QUERY Command. READ operations during the PROGRAM operation will output the status register on the data I/Os. (See Registers.)
After the PROGRAM operation has completed, the memory returns to read mode, unless an error has occurred. When an error occurs, the memory continues to output the
status register. A READ/RESET command must be issued to reset the error condition
and return to read mode.
Note that the PROGRAM command cannot change a bit set at 0 back to 1. One of the
ERASE commands must be used to set all the bits in a block, or in the whole device,
from 0 to 1.
UNLOCK BYPASS Command
The UNLOCK BYPASS command is used in conjunction with the UNLOCK BYPASS
PROGRAM command to program the memory. When the access time to the device is
long (as with some EPROM programmers), considerable time saving can be made by
using these commands. Three WRITE operations are required to issue the UNLOCK BYPASS command.

M29FxxxFT/B
Command Interface
Once the UNLOCK BYPASS command has been issued, the memory will only accept the
UNLOCK BYPASS PROGRAM command and the UNLOCK BYPASS RESET command.
The memory can be read as though in read mode.
UNLOCK BYPASS PROGRAM Command
The UNLOCK BYPASS PROGRAM command can be used to program one address in
memory at a time. The command requires two WRITE operations, the final write operation latches the address and data, and starts the program/erase controller.
The PROGRAM operation using the UNLOCK BYPASS PROGRAM command behaves
identically to the PROGRAM operation using the PROGRAM command. A protected
block cannot be programmed; the operation cannot be aborted and the status register
is read. Errors must be reset using the READ/RESET command, which leaves the device
in unlock bypass mode. (See the PROGRAM command for details.)
UNLOCK BYPASS RESET Command
The UNLOCK BYPASS RESET command can be used to return to read/reset mode from
unlock bypass mode. Two WRITE operations are required to issue the UNLOCK BYPASS
RESET command. The READ/RESET command does not exit from unlock bypass mode.
CHIP ERASE Command
The CHIP ERASE command can be used to erase the entire chip. Six WRITE operations
are required to issue the CHIP ERASE command and start the program/erase controller.
If any blocks are protected then these are ignored and all the other blocks are erased. If
all of the blocks are protected, the CHIP ERASE operation appears to start but will terminate within about 100µs, leaving the data unchanged. No error condition is given
when protected blocks are ignored.
During an ERASE operation, the memory will ignore all commands. It is not possible to
issue any command to abort the operation. Typical chip erase times are given in READ
CFI QUERY Command. All READ operations during the CHIP ERASE operation will output the status register on the data I/Os. (See Registers for more details.)
After the CHIP ERASE operation has completed, the memory will return to read mode,
unless an error has occurred. When an error occurs, the memory will continue to output the status register. A READ/RESET command must be issued to reset the error condition and return to read mode.
The CHIP ERASE command sets all of the bits in unprotected blocks to 1. All previous
data is lost.
BLOCK ERASE Command
The BLOCK ERASE command can be used to erase a list of one or more blocks. Six
WRITE operations are required to select the first block in the list. Each additional block
in the list can be selected by repeating the sixth WRITE operation, using the address of
the additional block. The BLOCK ERASE operation starts the program/erase controller
about 50µs after the last WRITE operation. Once the program/erase controller starts, it
is not possible to select any more blocks. Each additional block must therefore be selected within 50µs of the last block. The 50µs timer restarts when an additional block is selected. The status register can be read after the sixth WRITE operation. See Status Regis-

Command Interface
ter for details on how to identify whether the program/erase controller has started the
BLOCK ERASE operation.
If any selected blocks are protected, then these are ignored and all the other selected
blocks are erased. If all of the selected blocks are protected, the BLOCK ERASE operation appears to start but will terminate within about 100µs, leaving the data unchanged.
No error condition is given when protected blocks are ignored.
During the BLOCK ERASE operation, the device will ignore all commands except the
ERASE SUSPEND command. All READ operations during the BLOCK ERASE operation
will output the status register on the data I/Os.
After the BLOCK ERASE operation has completed, the device will return to read mode,
unless an error has occurred. When an error occurs, the device will continue to output
the status register. A READ/RESET command must be issued to reset the error condition and return to read mode.
The BLOCK ERASE command sets all of the bits in the unprotected selected blocks to 1.
All previous data in the selected blocks is lost.
ERASE SUSPEND Command
The ERASE SUSPEND command may be used to temporarily suspend a BLOCK ERASE
operation and return the device to read mode. The command requires one WRITE operation.
The program/erase controller will suspend within the erase suspend latency time of the
ERASE SUSPEND command being issued. Once the program/erase controller has stopped, the device will be set to read mode and the erase will be suspended. If the ERASE
SUSPEND command is issued during the period when the device is waiting for an additional block (before the program/erase controller starts), then the erase is suspended
immediately and will start immediately when the ERASE SUSPEND command is issued.
It is not possible to select any further blocks to erase after the erase resume.
During erase suspend, it is possible to read and program cells in blocks that are not being erased; both READ and PROGRAM operations behave as normal on these blocks. If
any attempt is made to program in a protected block or in the suspended block then the
PROGRAM command is ignored and the data remains unchanged. The status register is
not read and no error condition is given. Reading from blocks that are being erased will
output the status register.
It is also possible to issue the AUTO SELECT, READ CFI QUERY, and UNLOCK BYPASS
commands during an erase suspend. The READ/RESET command must be issued to return the device to read array mode before the RESUME command will be accepted.
ERASE RESUME Command
The ERASE RESUME command must be used to restart the program/erase controller
from erase suspend. An erase can be suspended and resumed more than once.
READ CFI QUERY Command
The READ CFI QUERY command reads data from the CFI. This command is valid when
the device is in read array mode, or when the device is in auto select mode. One WRITE
cycle is required to issue the READ CFI QUERY command. Once the command is issued,
subsequent READ operations then read from the CFI. The READ/RESET command

Block Protection Operations
Block Protection Operations
Block protection can be used to prevent any operation from modifying the data stored
in the Flash memory. Each Block can be protected individually. Once protected, Program and Erase operations on the block fail to change the data. Block protection status
of the device is read using the AUTO SELECT command.
Two techniques for controlling block protection are explained here: Programmer technique and In-System technique.
Note: A third technique for controlling block protection, Temporary Unprotection, is
described in the Signal Descriptions table, RP pin (Reset/Block Temporary Unprotection).
Unlike the Command Interface of the Program/Erase Controller, the techniques for protecting and unprotecting blocks could change between different Flash memory suppliers.

Programmer Technique
The Programmer technique uses high (VID) voltage levels on some of the bus pins.
These cannot be achieved using a standard microprocessor bus, therefore the technique is recommended only for use in Programming Equipment.
To protect a block, follow the Programmer Equipment Block Protect flowchart. During
the Block Protect algorithm, the A19-A12 Address Inputs indicate the address of the
block to be protected. The block will be correctly protected only if A19-A12 remain valid
and stable, and if Chip Enable is kept Low, V IL, all along the Protect and Verify phases.
The Chip Unprotect algorithm is used to unprotect all the memory blocks at the same
time. This algorithm can only be used if all of the blocks are protected first. To unprotect
the chip follow the Programmer Equipment Chip Unprotect flowchart and the Programmer Technique Block Protection table, which give a summary of each operation.
The timing on these flowcharts is critical. Care should be taken to ensure that, where a
pause is specified, it is followed as closely as possible. Do not abort the procedure before reaching the end. Chip Unprotect can take several seconds and a user message
should be provided to show that the operation is progressing.

Block Protection Operations
1. Address Inputs A[9:12] give the address of the block that is to be protected. It is imperative that they remain stable during the operation.
2. During the protect and verify phases of the algorithm, CE# must be kept LOW.
Notes:
In-System Technique
The In-System technique requires a high voltage level on the Reset/Blocks Temporary
Unprotect pin, RP. This can be achieved without violating the maximum ratings of the
components on the microprocessor bus, therefore this technique is suitable for use after the Flash memory has been fitted to the system.
To protect a block follow the In-System Equipment Block Protect flowchart . To unprotect the whole chip it is necessary to protect all of the blocks first, then all the blocks can
be unprotected at the same time. To unprotect the chip follow the In-System Equipment Chip Unprotect flowchart.
The timing on these flowcharts is critical. Care should be taken to ensure that, where a
pause is specified, it is followed as closely as possible. Do not allow the microprocessor
to service interrupts that will upset the timing and do not abort the procedure before
reaching the end. Chip Unprotect can take several seconds and a user message should
be provided to show that the operation is progressing.

Data Polling Bit
The Data Polling Bit (DQ7) can be used to identify whether the Program/Erase Controller has successfully completed its operation or if it has responded to an Erase Suspend.
The Data Polling Bit is output on DQ7 when the Status Register is read.
During Program operations the Data Polling Bit outputs the complement of the bit being programmed to DQ7. After successful completion of the Program operation the
memory returns to Read mode and Bus Read operations from the address just programmed output DQ7, not its complement.
During Erase operations the Data Polling Bit outputs ’0’, the complement of the erased
state of DQ7. After successful completion of the Erase operation the memory returns to
Read Mode.
In Erase Suspend mode the Data Polling Bit will output a ’1’ during a Bus Read operation within a block being erased. The Data Polling Bit will change from a ’0’ to a ’1’
when the Program/Erase Controller has suspended the Erase operation.
The Data Polling Flowchart, gives an example of how to use the Data Polling Bit. A Valid
Address is the address being programmed or an address within the block being erased.

Toggle Bit
The Toggle Bit (DQ6) can be used to identify whether the Program/Erase Controller has
successfully completed its operation or if it has responded to an Erase Suspend. The
Toggle Bit is output on DQ6 when the Status Register is read.
During Program and Erase operations the Toggle Bit changes from ’0’ to ’1’ to ’0’, etc.,
with successive Bus Read operations at any address. After successful completion of the
operation the memory returns to Read mode.
During Erase Suspend mode the Toggle Bit will output when addressing a cell within a
block being erased. The Toggle Bit will stop toggling when the Program/Erase Controller
has suspended the Erase operation.
If any attempt is made to erase a protected block, the operation is aborted, no error is
signalled and DQ6 toggles for approximately 100µs. If any attempt is made to program a
protected block or a suspended block, the operation is aborted, no error is signalled and
DQ6 toggles for approximately 1µs.
The Data Toggle Flowchart, gives an example of how to use the Data Toggle Bit.

Error Bit
The Error Bit (DQ5) can be used to identify errors detected by the Program/Erase Controller. The Error Bit is set to ’1’ when a Program, Block Erase or Chip Erase operation
fails to write the correct data to the memory. If the Error Bit is set a Read/Reset command must be issued before other commands are issued. The Error bit is output on
DQ5 when the Status Register is read.
Note that the Program command cannot change a bit set to ’0’ back to ’1’ and attempting to do so will set DQ5 to ‘1’. A Bus Read operation to that address will show the bit is
still ‘0’. One of the Erase commands must be used to set all the bits in a block or in the
whole memory from ’0’ to ’1’
Erase Timer Bit
The Erase Timer Bit (DQ3) can be used to identify the start of Program/Erase Controller
operation during a Block Erase command. Once the Program/Erase Controller starts
erasing the Erase Timer Bit is set to ’1’. Before the Program/Erase Controller starts the
Erase Timer Bit is set to ’0’ and additional blocks to be erased may be written to the
Command Interface. The Erase Timer Bit is output on DQ3 when the Status Register is
read.

Status Register
Alternative Toggle Bit
The Alternative Toggle Bit (DQ2) can be used to monitor the Program/Erase controller
during Erase operations. The Alternative Toggle Bit is output on DQ2 when the Status
Register is read.
During Chip Erase and Block Erase operations the Toggle Bit changes from ’0’ to ’1’
to ’0’, etc., with successive Bus Read operations from addresses within the blocks being
erased. A protected block is treated the same as a block not being erased. Once the operation completes the memory returns to Read mode.
During Erase Suspend the Alternative Toggle Bit changes from ’0’ to ’1’ to ’0’, etc. with
successive Bus Read operations from addresses within the blocks being erased. Bus
Read operations to addresses within blocks not being erased will output the memory
cell data as if in Read mode.
After an Erase operation that causes the Error Bit to be set the Alternative Toggle Bit can
be used to identify which block or blocks have caused the error. The Alternative Toggle
Bit changes from ’0’ to ’1’ to ’0’, etc. with successive Bus Read Operations from addresses within blocks that have not erased correctly. The Alternative Toggle Bit does not
change if the addressed block has erased correctly.

Common Flash Interface (CFI)
Common Flash Interface (CFI)
The Common Flash Interface is a JEDEC approved, standardized data structure that can
be read from the Flash memory device. It allows a system software to query the device
to determine various electrical and timing parameters, density information and functions supported by the memory. The system can interface easily with the device, enabling the software to upgrade itself when necessary.
When the CFI Query Command is issued the device enters CFI Query mode and the data structure is read from the memory. Addresses used to retrieve the data are shown in
the following tables:
The CFI data structure also contains a security area where a 64-bit unique security
number is written. This area can be accessed only in Read mode by the final user. It is
impossible to change the security number after it has been written by Micron. Issue a
Read command to return to Read mode.
