■ GENERAL DESCRIPTION
The MBM29LV160T/B is a 16M-bit, 3.0 V-only Flash memory organized as 2M bytes of 8 bits each or 1M words
of 16 bits each. The MBM29LV160T/B is offered in a 48-pin TSOP (I), 46-pin SON, 48-pin CSOP and 48-ball
FBGA packages. The device is designed to be programmed in-system with the standard system 3.0 V VCC supply.
12.0 V VPP and 5.0 V VCC are not required for write or erase operations. The device can also be reprogrammed
in standard EPROM programmers.
The standard MBM29LV160T/B offers access times of 80 ns and 120 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.
The MBM29LV160T/B is pin and command set compatible with JEDEC standard E2PROMs. 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 device is
similar to reading from 5.0 V and 12.0 V Flash or EPROM devices.
The MBM29LV160T/B 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 margins. Typically, each sector can be programmed and verified in about 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 margins.
Any individual sector is typically erased and verified in 1.0 second. (If already preprogrammed.)
The device also features a sector erase architecture. The sector mode allows each sector to be erased and
reprogrammed without affecting other sectors. The MBM29LV160T/B is erased when shipped from the factory.
The device features single 3.0 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
comleted, the device internally resets to the read mode.
The MBM29LV160T/B also has a hardware RESET pin. When this pin is driven low, execution of any Embedded
Program Algorithm or Embedded Erase Algorithm is terminated. The internal state machine is then reset to the
read mode. The RESET pin may be tied to the system reset circuitry. Therefore, if a system reset occurs during
the Embedded Program Algorithm or Embedded Erase Algorithm, the device is automatically reset to the read
mode and will have erroneous data stored in the address locations being programmed or erased. These locations
need re-writing after the Reset. Resetting the device enables the system’s microprocessor to read the boot-up
firmware from the Flash memory.
Fujitsu’s Flash technology combines years of Flash memory manufacturing experience to produce the highest
levels of quality, reliability, and cost effectiveness. The MBM29LV160T/B memory electrically erases 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.

■ FUNCTIONAL DESCRIPTION
Read Mode
The MBM29LV160T/B 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 - tOE time.) See Figure 5.1 for timing specifications.
Standby Mode
There are two ways to implement the standby mode on the MBM29LV160T/B devices. One is by 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. During Embedded Algorithm operation, VCC
Active current (ICC2) is required even CE = “H”. 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 the RESET input held at VSS ±0.3 V
(CE = “H” or “L”). Under this condition the current consumed is less than 5 µA max. 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.
Automatic Sleep Mode
There is a function called automatic sleep mode to restrain power consumption during read-out of
MBM29LV160T/B data. This mode can be used effectively with an application requesting low power consumption
such as handy terminals.
To activate this mode, MBM29LV160T/B automatically switches itself to low power mode when addresses remain
stable for 150 ns. It is not necessary to control CE, WE, and OE in this mode. During such mode, the current
consumed is typically 1 µA (CMOS Level).
Standard address access timings provide new data when addresses are changed. While in sleep mode, output
data is latched and always available to the system.
Output Disable
If the OE input is 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. The intent is to allow programming equipment to automatically match the device to be programmed
with its corresponding programming algorithm. The Autoselect command may also be used to check the status
of write-protected sectors. (See Tables 4.1 and 4.2.) 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 Table 2 or Table 3.)
12
MBM29LV160T-80/-90/-12/MBM29LV160B-80/-90/-12
The manufacturer and device codes may also be read via the command register, for instances when the
MBM29LV160T/B is erased or programmed in a system without access to high voltage on the A9 pin. The
command sequence is illustrated in Table 7, Command Definitions.
Byte 0 (A0 = VIL) represents the manufacture’s code and byte 1 (A0 = VIH) represents the device identifier code.
For the MBM29LV160T/B these two bytes are given in the Table 4.2. All identifiers for manufactures 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 Tables 2 or 3.) For device indentification in word mode (BYTE = VIH), DQ9
and DQ13 are equal to ‘1’ and DQ8, DQ10 to DQ12, DQ14, and DQ15 are equal to ‘0’.
If BYTE = VIL (for byte mode), the device code is C4H (for top boot block) or 49H (for bottom boot block). If BYTE
= VIH (for word mode), the device code is 22C4H (for top boot block) or 2249H (for bottom boot block).
In order to determine which sectors are write protected, A1 must be at VIH while running through the sector
addresses; if the selected sector is protected, a logical ‘1’ will be output on DQ0 (DQ0 =1).

MBM29LV160T-80/-90/-12/MBM29LV160B-80/-90/-12
Write
Device erasure and programming are accomplished via the command register. 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 CE or
WE, whichever occurs later, while data is latched on the rising edge of CE or WE pulse, whichever occurs first.
Standard microprocessor write timings are used. See Figures 6 to 8.
Refer to AC Write Characteristics and the Erase/Programming Waveforms for specific timing parameters.
Sector Protection
The MBM29LV160T/B features hardware sector protection. This feature will disable both program and erase
operations in any number of sectors (0 through 34). 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, CE =
VIL, A0 = A6 = VIL, A1 = VIH. The sector addresses pins (A19, A18, A17, A16, A15, A14, A13, and A12) should be set to
the sector to be protected. Tables 5 and 6 define the sector address for each of the thirty five (35) 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. See figures 16
and 24 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 (A19, A18, 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. Otherwise the
device will read 00H for an unprotected sector. In this mode, the lower order addresses, except for A0, A1, and
A6 are DON’T CARES. Address locations with A1 = VIL are reserved for Autoselect manufacturer and device
codes. A-1 requires to VIL in 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 pins (A19, A18, A17, A16, A15,
A14, A13, and A12) represents the sector address will produce a logical “1” at DQ0 for a protected sector. See
Tables 4.1 and 4.2 for Autoselect codes.
Temporary Sector Unprotection
This feature allows temporary unprotection of previously protected sectors of the MBM29LV160T/B devices 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.
(See Figures 18 and 25.)

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 an improper sequence will reset the device to the
read mode. Table 7 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 DQ0 to DQ7 and DQ8 to DQ15 bits are ignored.
Read/Reset Command
In order to return from Autoselect mode or Exceeded Timing Limits (DQ5 = 1) to read mode, the read/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 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 contents occurs during the power transition. Refer to the AC Read
Characteristics and Waveforms for specific timing parameters. (See Figure 5.1.)
Autoselect Command
Flash memories are intended for use in applications where the local CPU alters memory contents. As such,
manufactures and device codes must be accessible while the device resides 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.
18
MBM29LV160T-80/-90/-12/MBM29LV160B-80/-90/-12
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 last 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) retrieves the device code (MBM29LV160T = C4H and
MBM29LV160B = 49H for ×8 mode; MBM29LV160T = 22C4H and MBM29LV160B = 2249H for ×16 mode). (See
Tables 4.1 and 4.2.)
All manufactures and device codes will exhibit odd parity with DQ7 defined as the parity bit.
The sector state (protection or unprotection) will be indicated by address XX02H for ×16 (XX04H for ×8).
Scanning the sector addresses (A19, A18, 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 verification on the protected sector. (See Tables 2 and 3.)
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, by executing it after writing the Read/Reset command
sequence.
Word/Byte 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 the last CE or WE (whichever happens
first) begins programming. Upon executing the Embedded Program 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. (See Figures 6 and 7.)
The automatic programming operation is completed when the data on DQ7 is equivalent to data written to this
bit at which time the device return to the read mode and addresses are no longer latched. (See Table 8, Hardware
Sequence Flags.) Therefore, the device requires that a valid address be supplied by the system at this time.
Hence, Data Polling must be performed at the memory location which is being programmed.
Any commands written to the chip during this period will be ignored. If hardware reset occures during the
programming operation, it is impossible to guarantee whether the data being written is correct or not.
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.
Figure 20 illustrates the Embedded ProgramTM 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 Erase
Algorithm command sequence the device will automatically program and verify the entire memory for an all zero
data pattern prior to electrical erase. (Preprogram Function.) 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 mode.
(See Figure 8.)
Figure 21 illustrates the Embedded EraseTM Algorithm using typical command strings and bus operations.
Sector Erase
19
MBM29LV160T-80/-90/-12/MBM29LV160B-80/-90/-12
Sector erase is a six-bus cycle operation. There are two “unlock” write cycles, 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 a 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 six-bus cycle operations on Table 7. 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 time-out 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 device to the read mode, ignoring the previous
command string. Resetting the device once excution has begun will corrupt the data in the sector. In that case,
restart the erase on those sectors and allow them to complete. (Refer to the Write Operation Status section for
Sector Erase Timer operation.) Loading the sector erase buffer may be done in any sequence and with any
number of sectors (0 to 34).
Sector erase does not require the user to program the device prior to erase. The device automatically programs
all memory locations in the sector(s) to be erased prior to electrical erase (Preprogram Function). 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. (See Figure 8.)
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 section)
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. Multiple Sector Erase Time; [Sector Program Time (Preprogramming) + Sector Erase
Time] × Number of Sector Erase.
Figure 21 illustrates the Embedded EraseTM Algorithm using typical command strings and bus operations.
Erase Suspend/Resume
The Erase Suspend command allows the user to interrupt a Sector Erase operation and then perform data reads
from or program 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 commands.
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 devices have 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 the section on DQ2.)
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
20
MBM29LV160T-80/-90/-12/MBM29LV160B-80/-90/-12
be programmed to sectors that are not erase-suspended. Successively reading from the erase-suspended sector
while the devices are in the erase-suspend-program mode will cause DQ2 to toggle. The end of the erasesuspended Program operation is detected by the RY/BY output pin, Data polling of DQ7, or the Toggle Bit (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.
Extended Command
(1) Fast Mode
MBM29LV160T/B has Fast Mode function. This mode dispenses with the initial two unlock cycles required
in the standard program command sequence writing Fast Mode command into the command register. In this
mode, the required bus cycle for programming is two cycles instead of four bus cycles in standard program
command. (Do not write erase command in this mode.) The read operation is also executed after exiting this
mode. To exit this mode, it is necessary to write Fast Mode Reset command into the command register.
(Refer to the Figure 26 Extended algorithm.) The VCC active current is required even CE = VIH during Fast
Mode.
(2) Fast Programming
During Fast Mode, the programming can be executed with two bus cycles operation. The Embedded Program
Algorithm is executed by writing program set-up command (A0H) and data write cycles (PA/PD). (Refer to
the Figure 26 Extended algorithm.)
(3) CFI (Common Flash Memory Interface)
The CFI (Common Flash Memory Interface) specification outlines device and host system software
interrogation handshake which allows specific vendor-specified software algorithms to be used for entire
families of devices. This allows device-independent, JEDEC ID-independent, and forward-and backwardcompatible software support for the specified flash device families. Refer to CFI specification in detail.
The operation is initiated by writing the query command (98H) into the command register. Following the
command write, a read cycle from specific address retrives device information. Please note that output data
of upper byte (DQ8 to DQ15) is “0” in word mode (16 bit) read. Refer to the CFI code table. To terminate
operation, it is necessary to write the read/reset command sequence into the register.
(4) Extended Sector Protect
In addition to normal sector protection, the MBM29LV160T/B has Extended Sector Protection as extended
function. This function enable to protect sector by forcing VID on RESET pin and write a commnad sequence.
Unlike conventional procedure, it is not necessary to force VID and control timing for control pins. The only
RESET pin requires VID for sector protection in this mode. The extended sector protect requires VID on RESET
pin. With this condition, the operation is initiated by writing the set-up command (60H) into the command
register. Then, the sector addresses pins (A19, A18, A17, A16, A15, A14, A13 and A12) and (A6, A1, A0) = (0, 1, 0)
should be set to the sector to be protected (recommend to set VIL for the other addresses pins), and write
extended sector protect command (60H). A sector is typically protected in 150 µs. To verify programming of
the protection circuitry, the sector addresses pins (A19, A18, A17, A16, A15, A14, A13 and A12) and (A6, A1, A0) =
(0, 1, 0) should be set and write a command (40H). Following the command write, a logical “1” at device
output DQ0 will produce for protected sector in the read operation. If the output data is logical “0”, please
repeat to write extended sector protect command (60H) again. To terminate the operation, it is necessary
to set RESET pin to VIH.

3. DQ0 and DQ1 are reserve pins for future use.
4. DQ4 is Fujitsu internal use only.
DQ7
Data Polling
The MBM29LV160T/B device features 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
devices 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 Figure 22.
For chip erase and sector erase, Data Polling is valid after the rising edge of the sixth WE pulse in the six-write
pulse sequence. Data Polling must be performed at a sector address within any of the sectors being erased and
not at a protected sector. Otherwise, the status may not be valid. Once the Embedded Algorithm operation is
close to being completed, the MBM29LV160T/B 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 Program Algorithm
operation and DQ7 has a valid data, the data outputs on DQ0 to DQ6 may be still invalid. The valid data on DQ0
to DQ7 will be read on successive read attempts.
The Data Polling feature is only active during the Embedded Programming Algorithm, Embedded Erase Algorithm
or sector erase time-out.
See Figure 9 for the Data Polling timing specifications and diagrams.
22
MBM29LV160T-80/-90/-12/MBM29LV160B-80/-90/-12
DQ6
Toggle Bit I
The MBM29LV160T/B 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 can be read on the next successive attempts. During
programming, the Toggle Bit I is valid after the rising edge of the fourth WE 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 WE pulse in the sixwrite 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 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 I for about
200 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 the DQ6 to toggle.
See Figure 10 and Figure 23 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 device under this
condition. The CE circuit will partially power down the device under these conditions. The OE and WE pins will
control the output disable functions as described in Tables 2 and 3.
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 completes the Embedded Algorithm operation. Hence, the system never
reads a valid data on DQ7 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.
If this occurs, reset the device with command sequence.
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 I 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 is high on the
second status check, the command may not have been accepted.

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 DQ2.
DQ6 is different from DQ2 in that DQ6 toggles only when the standard program or Erase, or Erase Suspend
Program operation is in progress.
For example, DQ2 and DQ6 can be used together to determine if the erase-suspend-read mode is in progress.
(DQ2 toggles while DQ6 does not.) See also Table 10 and Figure 19.
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 an erasing sector.

toggle.
RY/BY
Ready/Busy Pin
The MBM29LV160T/B provides a RY/BY open-drain output pin as a way to indicate to the host system that the
Embedded Algorithms are either in progress or has been 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 devices will not accept any additional program or erase commands
with the exception of the Erase Suspend command. If the MBM29LV160T/B is placed in an Erase Suspend
mode, the RY/BY output will be high, by means of connecting with a pull-up resister to VCC.
During programming, the RY/BY pin is driven low after the rising edge of the fourth WE pulse. During an erase
operation, the RY/BY pin is driven low after the rising edge of the sixth WE pulse. The RY/BY pin will indicate a
busy condition during the RESET pulse. See Figure 11 and 12 for a detailed timing diagram. The RY/BY pin is
pulled high in standby mode.
Since this is an open-drain output, RY/BY pins can be tied together in parallel with a pull-up resistor to VCC.

MBM29LV160T-80/-90/-12/MBM29LV160B-80/-90/-12
RESET
Hardware Reset Pin
The MBM29LV160T/B 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 tREADY after the RESET pin is driven low. Furthermore, once the RESET pin goes high, the
device requires an additional tRH before it allows 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 Figure 12 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) will
need to be erased again before they can be programmed.
Word/Byte Configuration
The BYTE pin selects the byte (8-bit) mode or word (16-bit) mode for the MBM29LV160T/B device. When this
pin is driven high, the device operates in the word (16-bit) mode. The data is read and programmed at DQ0 to
DQ15. When this pin is driven low, the device operates in byte (8-bit) mode. Under this mode, DQ15/A-1 pin becomes
the lowest address bit and DQ8 to DQ14 bits are tri-stated. However, the command bus cycle is always an 8-bit
operation and hence commands are written at DQ0 to DQ7 and DQ8 to DQ15 bits are ignored. Refer to Figures
13 and 14 for the timing diagrams.
Data Protection
The MBM29LV160T/B 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 to 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 sequence.
The device also incorporates 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 2.3 V (typically 2.4 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 2.3 V.
If the Embedded Erase Algorithm is interrupted, there is possibility that the erasing sector(s) will need to be
erased again prior to programming.
Write Pulse “Glitch” Protection
Noise pulses of less than 5 ns (typical) on OE, CE, or WE will not change the command registers.
Logical Inhibit
Writing is inhibited by holding any one of OE = VIL, CE = VIH, or WE = VIH. To initiate a write, CE and WE must
be a logical zero while OE is a logical one.
Power-up Write Inhibit
Power-up of the devices 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 read mode on power-up.
Handling of SON Package
The metal portion of marking side is connected with internal chip electrically. Please pay attention not to occur
electrical connection during operation. In worst case, it may be caused permanent damage to device or system
by excessive current.
