MBM29F400TC-55/-70/-90/MBM29F400BC-55/-70/-90
■ DESCRIPTION
The MBM29F400TC/BC is a 4M-bit, 5.0 V-only Flash memory organized as 512K bytes of 8 bits each or 256K
words of 16 bits each. The MBM29F400TC/BC is offered in a 48-pin TSOP and 44-pin SOP packages. This device
is designed to be programmed in-system with the standard system 5.0 V VCC supply. 12.0 V VPP is not required
for write or erase operations. The devices can also be reprogrammed in standard EPROM programmers. The
standard MBM29F400TC/BC offers access times 55 ns and 90 ns allowing operation of high-speed microprocessors without wait states. To eliminate bus contention the device has separate chip enable (CE), write enable (WE),
and output enable (OE) controls.

(Continued)
The MBM29F400TC/BC is pin and command set compatible with JEDEC standard. Commands are written to
the command register using standard microprocessor write timings. Register contents serve as input to an
internal state-machine which controls the erase and programming circuitry. Write cycles also internally latch
addresses and data needed for the programming and erase operations. Reading data out of the devices is similar
to reading from12.0 V Flash or EPROM devices.
The MBM29F400TC/BC is programmed by executing the program command sequence. This will invoke the
Embedded Program Algorithm which is an internal algorithm that automatically times the program pulse widths
and verifies proper cell margin. Typically, each sector can be programmed and verified in less than 0.5 seconds.
Erase is accomplished by executing the erase command sequence. This will invoke the Embedded Erase
Algorithm which is an internal algorithm that automatically preprograms the array if it is not already programmed
before executing the erase operation. During erase, the device automatically times the erase pulse widths and
verifies proper cell margin.
A sector is typically erased and verified in 1.0 second (if already completely preprogrammed.).
The devices also features a sector erase architecture. The sector mode allows each sector to be erased and
reprogrammed without affecting other sectors. The MBM29F400TC/BC is erased when shipped from the factory.
The devices features single 5.0 V power supply operation for both read and write functions. Internally generated
and regulated voltages are provided for the program and erase operations. A low VCC detector automatically
inhibits write operations on the loss of power. The end of program or erase is detected by Data Polling of DQ7,
by the Toggle Bit feature on DQ6, or the RY/BY output pin. Once the end of a program or erase cycle has been
completed, the device internally resets to the read mode.
Fujitsu’s Flash technology combines years of EPROM and E2PROM experience to produce the highest levels
of quality, reliability, and cost effectiveness. The MBM29F400TC/BC memory electrically erase the entire chip
or all bits within a sector simultaneously via Fowler-Nordhiem tunneling. The bytes/words are programmed one
byte/word at a time using the EPROM programming mechanism of hot electron injection.

Notes: • Address bits A15 to A11 = X = “H” or “L” for all address commands except or Program Address (PA) and
Sector Address (SA).
• Bus operations are defined in “MBM29F400TC/BC User Bus Operation (BYTE = VIH)” and
“MBM29F400TC/BC User Bus Operation (BYTE = VIL)” in ■DEVICE BUS OPERATION.
• RA = Address of the memory location to be read.
PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of
the WE pulse.
SA = Address of the sector to be erased. The combination of A17, A16, A15, A14, A13, and A12 will
uniquely select any sector.
• RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the rising edge of WE.
• The system should generate the following address patterns:
Word Mode: 555h or 2AAh to addresses A10 to A0
Byte Mode: AAAh or 555h to addresses A10 to A-1
• Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
• Command combinations not described in Command Definitions table are illegal.

MBM29F400TC-55/-70-90/MBM29F400BC-55/-70-90
■ FUNCTIONAL DESCRIPTION
Read Mode
The MBM29F400TC/BC has two control functions which must be satisfied in order to obtain data at the outputs.
CE is the power control and should be used for a device selection. OE is the output control and should be used
to gate data to the output pins if a device is selected.
Address access time (tACC) is equal to the delay from stable addresses to valid output data. The chip enable
access time (tCE) is the delay from stable addresses and stable CE to valid data at the output pins. The output
enable access time is the delay from the falling edge of OE to valid data at the output pins (Assuming the
addresses have been stable for at least tACC - tCE time).
Standby Mode
There are two ways to implement the standby mode on the MBM29F400TC/BC devices, one using both the CE
and RESET pins; the other via the RESET pin only.
When using both pins, a CMOS standby mode is achieved with CE and RESET inputs both held at VCC ± 0.3 V.
Under this condition the current consumed is less than 5 µA max. A TTL standby mode is achieved with CE and
RESET pins held at VIH. Under this condition the current is reduced to approximately 1mA. During Embedded
Algorithm operation, VCC Active current (ICC2) is required even CE = VIH. The device can be read with standard
access time (tCE) from either of these standby modes.
When using the RESET pin only, a CMOS standby mode is achieved with RESET input held at VSS ± 0.3 V
(CE = “H” or “L”). Under this condition the current is consumed is less than 5 µA max. A TTL standby mode is
achieved with RESET pin held at VIL, (CE= “H” or “L”). Under this condition the current required is reduced to
approximately 1mA. Once the RESET pin is taken high, the device requires tRH of wake up time before outputs
are valid for read access.
In the standby mode the outputs are in the high impedance state, independent of the OE input.
Output Disable
With the OE input at a logic high level (VIH), output from the device is disabled. This will cause the output pins
to be in a high impedance state.
Autoselect
The autoselect 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 devices to be programmed with its corresponding programming algorithm. This mode is functional over the
entire temperature range of the device.
To activate this mode, the programming equipment must force VID (11.5 V to 12.5 V) on address pin A9. Two
identifier bytes may then be sequenced from the devices outputs by toggling address A0 from VIL to VIH. All
addresses are don't cares except A0, A1 and A6 ( A-1) (See “MBM29F400TC/BC Sector Protection Verify
Autoselect Codes” in ■DEVICE BUS OPERATION).
The manufacturer and device codes may also be read via the command register, for instances when the
MBM29F400TC/BC is erased or programmed in a system without access to high voltage on the A9 pin. The
command sequence is illustrated in “MBM29F400TC/BC Command Definitions” in ■DEVICE BUS OPERATION
(refer to Autoselect Command section).
A0 = VIL represents the manufacturer’s code (Fujitsu = 04h) and A0 = VIH the device identifier code (MBM29F400TC
= 23h and MBM29F400BC = ABh for ×8 mode; MBM29F400TC = 2223h and MBM29F400BC = 22ABh for ×16
mode). These two bytes/words are given in “MBM29F400TC/BC Sector Protection Verify Autoselect Codes” and
“Expanded Autoselect Code Table” in ■DEVICE BUS OPERATION. All identifiers for manufacturer and device
will exhibit odd parity with DQ7 defined as the parity bit. In order to read the proper device codes when executing
the autoselect, A1 must be VIL (See “MBM29F400TC/BC Sector Protection Verify Autoselect Codes” and
“Expanded Autoselect Code Table” in ■DEVICE BUS OPERATION).
12
MBM29F400TC-55/-70-90/MBM29F400BC-55/-70-90
Write
Device erasure and programming are accomplished via the command register. The contents of the register serve
as inputs to the internal state machine. The state machine outputs dictate the function of the device.
The command register itself does not occupy any addressable memory location. The register is a latch used to
store the commands, along with the address and data information needed to execute the command. The
command register is written by bringing WE to VIL, while CE is at VIL and OE is at VIH. Addresses are latched on
the falling edge of WE or CE, whichever happens later; while data is latched on the rising edge of WE or CE,
whichever happens first. Standard microprocessor write timings are used.
Refer to AC Write Characteristics and the Erase/Programming Waveforms for specific timing parameters.
Sector Protection
The MBM29F400TC/BC features hardware sector protection. This feature will disable both program and erase
operations in any number of sectors (0 through 10). The sector protection feature is enabled using programming
equipment at the user’s site. The device is shipped with all sectors unprotected.
To activate this mode, the programming equipment must force VID on address pin A9 and control pin OE, (suggest
VID = 11.5V), CE = VIL, and A6 = VIL. The sector addresses (A17, A16, A15, A14, A13, and A12) should be set to the
sector to be protected. “Sector Address Table (MBM29F400TC)” and “Sector Address Table (MBM29F400BC)”
in ■FLEXIBLE SECTOR ERASE ARCHITECTURE define the sector address for each of the eleven (11)
individual sectors. Programming of the protection circuitry begins on the falling edge of the WE pulse and is
terminated with the rising edge of the same. Sector addresses must be held constant during the WE pulse. Refer
to “AC Waveforms for Sector Protection Timing Diagram” in ■TIMING DIAGRAM and “Sector Protection
Algorithm” in ■FLOW CHART for sector protection waveforms and algorithm.
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. Scanning the sector addresses (A17, A16, A15, A14, A13, and A12) while (A6,
A1, A0) = (0, 1, 0) will produce a logical “1” code at device output DQ0 for a protected sector. Otherwise the
devices will produce 00h for unprotected sector. In this mode, the lower order addresses, except for A0, A1, and
A6 are don't care. Address locations with A1 = VIL are reserved for Autoselect manufacturer and device codes.
A-1 requires to apply to VIL on byte mode.
It is also possible to determine if a sector is protected in the system by writing an Autoselect command. Performing
a read operation at the address location XX02h, where the higher order addresses (A17, A16, A15, A14, A13, and
A12) are the desired sector address will produce a logical “1” at DQ0 for a protected sector. See “MBM29F400TC/
BC Sector Protection Verify Autoselect Codes” and “Expanded Autoselect Code Table” in ■DEVICE BUS
OPERATION for Autoselect codes.
Temporary Sector Unprotection
This feature allows temporary unprotection of previously protected sectors of the MBM29F400TC/BC device in
order to change data. The Sector Unprotection mode is activated by setting the RESET pin to high voltage
(12 V). During this mode, formerly protected sectors can be programmed or erased by selecting the sector
addresses. Once the 12 V is taken away from the RESET pin, all the previously protected sectors will be protected
again. Refer to “Temporary Sector Unprotection Timing Diagram” in ■TIMING DIAGRAM and “Temporary Sector
Unprotection Algorithm” in ■FLOW CHART.
13
MBM29F400TC-55/-70-90/MBM29F400BC-55/-70-90
■ 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. “MBM29F400TC/BC Command Definitions” in ■DEVICE BUS OPERATION 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. Moreover both Read/Reset commands are functionally
equivalent, resetting the device to the read mode. Please note that commands are always written at DQ7 to DQ0
and DQ15 to DQ8 bits are ignored.
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 devices remain enabled for reads until the
command register contents are altered.
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.
Autoselect Command
Flash memories are intended for use in applications where the local CPU alters memory contents. As such,
manufacture and device codes must be accessible while the devices reside in the target system. PROM
programmers typically access the signature codes by raising A9 to a high voltage. However, multiplexing high
voltage onto the address lines is not generally desired system design practice.
The device contains an autoselect command operation to supplement traditional PROM programming
methodology. The operation is initiated by writing the autoselect command sequence into the command register.
Following the command write, a read cycle from address XX00h retrieves the manufacture code of 04h. A read
cycle from address XX01h for ×16 (XX02h for ×8) returns the device code (MBM29F400TC = 23h and
MBM29F400BC = ABh for ×8 mode; MBM29F400TC = 2223h and MBM29F400BC = 22ABh for ×16 mode).
(See “MBM29F400TC/BC Sector Protection Verify Autoselect Codes” and “Expanded Autoselect Code Table”
in ■DEVICE BUS OPERATION.)
All manufacturer and device codes will exhibit odd parity with DQ7 defined as the parity bit.
Scanning the sector addresses (A17, A16, A15, A14, A13, and A12) while (A6, A1, A0) = (0, 1, 0) will produce a logical
“1” at device output DQ0 for a protected sector. The programming verification should be perform margin mode
on the protected sector (See “MBM29F400TC/BC User Bus Operation (BYTE = VIH)” and “MBM29F400TC/BC
User Bus Operation (BYTE = VIL)” in ■DEVICE BUS OPERATION).
To terminate the operation, it is necessary to write the read/reset command sequence into the register and also
to write the autoselect command during the operation, execute it after writing read/reset command sequence.
Byte/Word Programming
The device is programmed on a byte-by-byte (or word-by-word) basis. Programming is a four bus cycle operation.
There are two “unlock” write cycles. These are followed by the program set-up command and data write cycles.
Addresses are latched on the falling edge of CE or WE, whichever happens later and the data is latched on the
rising edge of CE or WE, whichever happens first. The rising edge of CE or WE (whichever happens first) begins
programming. Upon executing the Embedded ProgramTM Algorithm command sequence the system is not
required to provide further controls or timings. The device will automatically provide adequate internally generated
program pulses and verify the programmed cell margin.
The automatic programming operation is completed when the data on DQ7 is equivalent to data written to this
bit at which time the devices return to the read mode and addresses are no longer latched (see “Hardware
Sequence Flags” , Hardware Sequence Flags) Therefore, the devices require that a valid address to the devices
be supplied by the system at this particular instance of time. Hence, Data Polling must be performed at the
memory location which is being programmed.
14
MBM29F400TC-55/-70-90/MBM29F400BC-55/-70-90
Any commands written to the chip during this period will be ignored. If hardware reset occurs during the
programming operation, it is impossible to guarantee the data are being written.
Programming is allowed in any sequence and across sector boundaries. Beware that a data “0” cannot be
programmed back to a “1”. Attempting to do so may either hang up the device or result in an apparent success
according to the data polling algorithm but a read from read/reset mode will show that the data is still “0”. Only
erase operations can convert “0”s to “1”s.
“Embedded Programming Algorithm” in ■FLOW CHART illustrates the Embedded Programming Algorithm using
typical command strings and bus operations.
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. Two more “unlock” write cycles are then followed by the chip erase command.
Chip erase does not require the user to program the device prior to erase. Upon executing the Embedded EraseTM
Algorithm command sequence the device will automatically program and verify the entire memory for an all zero
data pattern prior to electrical erase. The system is not required to provide any controls or timings during these
operations.
The automatic erase begins on the rising edge of the last WE pulse in the command sequence and terminates
when the data on DQ7 is “1” (see Write Operation Status section) at which time the device returns to read the
mode.
“Embedded Erase Algorithm” in ■FLOW CHART illustrates the Embedded Erase Algorithm using typical
command strings and bus operations.
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. Two more “unlock” write cycles are then followed by the sector erase command. The sector
address (any address location within the desired sector) is latched on the falling edge of WE, while the command
(Data = 30h) is latched on the rising edge of WE. After time-out of 50 µs from the rising edge of the last sector
erase command, the sector erase operation will begin.
Multiple sectors may be erased concurrently by writing the six bus cycle operations on “MBM29F400TC/BC
Command Definitions” in ■DEVICE BUS OPERATION. This sequence is followed with writes of the Sector Erase
command to addresses in other sectors desired to be concurrently erased. The time between writes must be
less than 50 µs otherwise that command will not be accepted and erasure will start. It is recommended that
processor interrupts be disabled during this time to guarantee this condition. The interrupts can be re-enabled
after the last Sector Erase command is written. A time-out of 50 µs from the rising edge of the last WE will initiate
the execution of the Sector Erase command(s). If another falling edge of the WE occurs within the 50 µs timeout window the timer is reset. (Monitor DQ3 to determine if the sector erase timer window is still open, see section
DQ3, Sector Erase Timer.) Any command other than Sector Erase or Erase Suspend during this time-out period
will reset the devices to the read mode, ignoring the previous command string. Resetting the device once
execution has begun will corrupt the data in that sector. In that case, restart the erase on those sectors and
allow them to complete. (Refer to “Write Operation Status” for Sector Erase Timer operation.) Loading the sector
erase buffer may be done in any sequence and with any number of sectors (0 to 10).
Sector erase does not require the user to program the devices prior to erase. The device automatically programs
all memory locations in the sector(s) to be erased prior to electrical erase. When erasing a sector or sectors the
remaining unselected sectors are not affected. The system is not required to provide any controls or timings
during these operations.
The automatic sector erase begins after the 50 µs time out from the rising edge of the WE pulse for the last
sector erase command pulse and terminates when the data on DQ7 is “1” (see “Write Operation Status”) at which
time the device returns to the read mode. Data polling must be performed at an address within any of the sectors
being erased.
15
MBM29F400TC-55/-70-90/MBM29F400BC-55/-70-90
“Embedded Erase Algorithm” in ■FLOW CHART illustrates the Embedded Erase Algorithm using typical
command strings and bus operations.
Erase Suspend
The Erase Suspend command allows the user to interrupt a Sector Erase operation and then perform data reads
from or programs to a sector not being erased. This command is applicable ONLY during the Sector Erase
operation which includes the time-out period for sector erase. The Erase Suspend command will be ignored if
written during the Chip Erase operation or Embedded Program Algorithm. Writting the Erase Suspend command
during the Sector Erase time-out results in immediate termination of the time-out period and suspension of the
erase operation.
Writing the Erase Resume command resumes the erase operation. The addresses are “don’t cares” when writing
the Erase Suspend or Erase Resume command.
When the Erase Suspend command is written during the Sector Erase operation, the device will take a maximum
of 20 µs to suspend the erase operation. When the device has entered the erase-suspended mode, the RY/BY
output pin and the DQ7 bit will be at logic “1”, and DQ6 will stop toggling. The user must use the address of the
erasing sector for reading DQ6 and DQ7 to determine if the erase operation has been suspended. Further writes
of the Erase Suspend command are ignored.
When the erase operation has been suspended, the device defaults to the erase-suspend-read mode. Reading
data in this mode is the same as reading from the standard read mode except that the data must be read from
sectors that have not been erase-suspended. Successively reading from the erase-suspended sector while the
device is in the erase-suspend-read mode will cause DQ2 to toggle. (See “DQ2 Toggle Bit II”).
After entering the erase-suspend-read mode, the user can program the device by writing the appropriate
command sequence for Program. This program mode is known as the erase-suspend-program mode. Again,
programming in this mode is the same as programming in the regular Program mode except that the data must
be programmed to sectors that are not erase-suspended. Successively reading from the erase-suspended sector
while the device is in the erase-suspend-program mode will cause DQ2 to toggle. The end of the erase-suspended
program operation is detected by the RY/BY output pin, Data polling of DQ7, or by the Toggle Bit I (DQ6) which
is the same as the regular Program operation. Note that DQ7 must be read from the program address while DQ6
can be read from any address.
To resume the operation of Sector Erase, the Resume command (30h) should be written. Any further writes of
the Resume command at this point will be ignored. Another Erase Suspend command can be written after the
chip has resumed erasing.

Notes: • DQ0 and DQ1 are reserve pins for future use. DQ4 is Fujitsu internal use only.
• DQ15 to DQ8 are “DON’T CARES” because there is for × 16 mode.
DQ7
Data Polling
The MBM29F400TC/BC device feature Data Polling as a method to indicate to the host that the Embedded
Algorithms are in progress or completed. During the Embedded Program Algorithm an attempt to read the device
will produce the complement of the data last written to DQ7. Upon completion of the Embedded Program
Algorithm, an attempt to read the device will produce the true data last written to DQ7. During the Embedded
Erase Algorithm, an attempt to read the device will produce a “0” at the DQ7 output. Upon completion of the
Embedded Erase Algorithm an attempt to read the device will produce a “1” at the DQ7 output. The flowchart
for Data Polling (DQ7) is shown in “Data Polling Algorithm” in ■FLOW CHART.
For Programing, the Data Polling is valid after the rising edge of fourth write pulse in the four write pulse sequence.
For chip erase and sector erase, the Data Polling is valid after the rising edge of the sixth write pulse in the six
write pulse sequence. Data Polling must be performed at sector address within any of the sectors being erased
and not a protected sector. Otherwise, the status may not be valid. Once the Embedded Algorithm operation is
close to being completed, the MBM29F400TC/BC data pins (DQ7) may change asynchronously while the output
enable (OE) is asserted low. This means that the device is driving status information on DQ7 at one instant of
time and then that byte’s valid data at the next instant of time. Depending on when the system samples the DQ7
output, it may read the status or valid data. Even if the device has completed the Embedded Algorithm operation
and DQ7 has a valid data, the data outputs on DQ6 to DQ0 may be still invalid. The valid data on DQ7 to DQ0 will
be read on the successive read attempts.
The Data Polling feature is only active during the Embedded Programming Algorithm, Embedded Erase Algorithm
or sector erase time-out (See “Hardware Sequence Flags”).
See “AC Waveforms for Data Polling during Embedded Algorithm Operations” in ■TIMING DIAGRAM for the
Data Polling timing specifications and diagrams.
17
MBM29F400TC-55/-70-90/MBM29F400BC-55/-70-90
DQ6
Toggle Bit I
The MBM29F400TC/BC also feature the “Toggle Bit I” as a method to indicate to the host system that the
Embedded Algorithms are in progress or completed.
During an Embedded Program or Erase Algorithm cycle, successive attempts to read (OE toggling) data from
the device will result in DQ6 toggling between one and zero. Once the Embedded Program or Erase Algorithm
cycle is completed, DQ6 will stop toggling and valid data will be read on the next successive attempts. During
programming, the Toggle Bit I is valid after the rising edge of the fourth write pulse in the four write pulse sequence.
For chip erase and sector erase, the Toggle Bit I is valid after the rising edge of the sixth write pulse in the six
write pulse sequence. The Toggle Bit I is active during the sector time out.
In programming, if the sector being written to is protected, the toggle bit l will toggle for about 2 µs and then stop
toggling without the data having changed. In erase, the device will erase all the selected sectors except for the
ones that are protected. If all selected sectors are protected, the chip will toggle the toggle bit for about 100 µs
and then drop back into read mode, having changed none of the data.
Either CE or OE toggling will cause the DQ6 to toggle. In addition, an Erase Suspend/Resume command will
cause DQ6 to toggle.
See “AC Waveforms for Toggle Bit I during Embedded Algorithm Operations” in ■TIMING DIAGRAM for the
Toggle Bit I timing specifications and diagrams.
DQ5
Exceeded Timing Limits
DQ5 will indicate if the program or erase time has exceeded the specified limits (internal pulse count). Under
these conditions DQ5 will produce a “1”. This is a failure condition which indicates that the program or erase
cycle was not successfully completed. Data Polling is the only operating function of the devices under this
condition. The CE circuit will partially power down the device under these conditions (to approximately 2 mA).
The OE and WE pins will control the output disable functions as described in “MBM29F400TC/BC User Bus
Operation (BYTE = VIH)” and “MBM29F400TC/BC User Bus Operation (BYTE = VIL)” in ■DEVICE BUS
OPERATION.
The DQ5 failure 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 complete the Embedded Algorithm operation. Hence, the system never
reads a valid data on DQ7 bit and DQ6 never stops toggling. Once the device has exceeded timing limits, the
DQ5 bit will indicate a “1.” Please note that this is not a device failure condition since the device was incorrectly
used.
DQ3
Sector Erase Timer
After the completion of the initial sector erase command sequence the sector erase time-out will begin. DQ3 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 I indicates the device has been written with a valid erase command, DQ3 may
be used to determine if the sector erase timer window is still open. If DQ3 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 I. If DQ3 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 DQ3 prior to and following each subsequent sector erase command. If DQ3 were high on the
second status check, the command may not have been accepted.
Refer to “Hardware Sequence Flags” : Hardware Sequence Flags.
18
MBM29F400TC-55/-70-90/MBM29F400BC-55/-70-90
DQ2
Toggle Bit II
This toggle bit II, along with DQ6, can be used to determine whether the device is in the Embedded Erase
Algorithm or in Erase Suspend.
Successive reads from the erasing sector will cause DQ2 to toggle during the Embedded Erase Algorithm. If the
device is in the erase-suspended-read mode, successive reads from the erase-suspended sector will cause DQ2
to toggle. When the device is in the erase-suspended-program mode, successive reads from the byte address
of the non-erase suspended sector will indicate a logic “1” at the DQ2 bit.
DQ6 is different from DQ2 in that DQ6 toggles only when the standard program or Erase, or Erase Suspend
Program operation is in progress. The behavior of these two status bits, along with that of DQ7, is summarized
as follows:

For example, DQ2 and DQ6 can be used together to determine the erase-suspend-read mode (DQ2 toggles while
DQ6 does not). See also “Hardware Sequence Flags” and “Toggle Bit Algorithm” in ■FLOW CHART.
Furthermore, DQ2 can also be used to determine which sector is being erased. When the device is in the erase
mode, DQ2 toggles if this bit is read from the erasing sector.
RY/BY
Ready/Busy
The MBM29F400TC/BC provides a RY/BY open-drain output pin as a way to indicate to the host system that
the EmbeddedTM Algorithms are either in progress or completed. If the output is low, the device is busy with
either a program or erase operation. If the output is high, the device is ready to accept any read/write or erase
operation. When the RY/BY pin is low, the device will not accept any additional program or erase commands. If
the MBM29F400TC/BC is placed in an Erase Suspend mode, the RY/BY output will be high. Also, since this is
an open drain output, many RY/BY pins can be tied together in parallel with a pull up resistor to VCC.
During programming, the RY/BY pin is driven low after the rising edge of the fourth write pulse. During an erase
operation, the RY/BY pin is driven low after the rising edge of the sixth write pulse. The RY/BY pin will indicate
a busy condition during the RESET pulse. Refer to “RY/BY Timing Diagram during Program/Erase Operations”
and “RESET/RY/BY Timing Diagram” in ■TIMING DIAGRAM for a detailed timing diagram.
Since this is an open-drain output, several RY/BY pins can be tied together in parallel with a pull-up resistor to VCC.

MBM29F400TC-55/-70-90/MBM29F400BC-55/-70-90
RESET
Hardware Reset
The MBM29F400TC/BC device may be reset by driving the RESET pin to VIL. The RESET pin has a pulse
requirement and has to be kept low (VIL) for at least 500 ns in order to properly reset the internal state machine.
Any operation in the process of being executed will be terminated and the internal state machine will be reset
to the read mode 20 µs after the RESET pin is driven low. Furthermore, once the RESET pin goes high, the
device requires time of tRH before it will allow read access. When the RESET pin is low, the device will be in the
standby mode for the duration of the pulse and all the data output pins will be tri-stated. If a hardware reset
occurs during a program or erase operation, the data at that particular location will be corrupted. Please note
that the RY/BY output signal should be ignored during the RESET pulse. Refer to “RESET/RY/BY Timing
Diagram” in ■TIMING DIAGRAM for the timing diagram. Refer to Temporary Sector Unprotection for additional
functionality.
If hardware reset occurs during Embedded Erase Algorithm, there is a possibility that the erasing sector(s)
cannot be used.
Byte/Word Configuration
The BYTE pin selects the byte (8-bit) mode or word (16-bit) mode for the MBM29F400TC/BC device. When this
pin is driven high, the device operates in the word (16-bit) mode. The data is read and programmed at DQ15 to
DQ0. When this pin is driven low, the device operates in byte (8-bit) mode. Under this mode, the DQ15/A-1 pin
becomes the lowest address bit and DQ14 to DQ8 bits are tri-stated. However, the command bus cycle is always
an 8-bit operation and hence commands are written at DQ7 to DQ0 and the DQ15 to DQ8 bits are ignored. Refer
to “Timing Diagram for Word Mode Configuration”, “Timing Diagram for Byte Mode Configuration” and “BYTE
Timing Diagram for Write Operations” in ■TIMING DIAGRAM for the timing diagram.
Data Protection
The MBM29F400TC/BC are 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 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 incorporate several features to prevent inadvertent write cycles resulting form 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 3.2 V (typically 3.7 V). 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 users responsibility to ensure that the control pins are logically correct
to prevent unintentional writes when VCC is above 3.2 V.
If Embedded Erase Algorithm is interrupted, there is possibility that the erasing sector(s) cannot be used.
Write Pulse “Glitch” Protection
Noise pulses of less than 3 ns (typical) on OE, 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.
Power-Up Write Inhibit
Power-up of the device with WE = CE = VIL and OE = VIH will not accept commands on the rising edge of WE.
The internal state machine is automatically reset to the read mode on power-up.
