■ DESCRIPTION
The MBM29DL640E is a 64 M-bit, 3.0 V-only Flash memory organized as 8 Mbytes of 8 bits each or 4 Mwords
of 16 bits each. The device is offered in 48-pin TSOP (I) and 63-ball FBGA packages. This device is designed to
be programmed in system with 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 device is organized into four physical banks: Bank A, Bank B, Bank C and Bank D, which can be considered
to be four separate memory arrays as far as certain operations are concerned. This device is the same as Fujitsu’s
standard 3 V only Flash memories with the additional capability of allowing a normal non-delayed read access
from a non-busy bank of the array while an embedded write (either a program or an erase) operation is simultaneously taking place on the other bank.

In the device, a new design concept called FlexBankTM *1 Architecture is implemented. Using this concept the
device can execute simultaneous operation between Bank 1, a bank chosen from among the four banks, and
Bank 2, a bank consisting of the three remaining banks. This means that any bank can be chosen as Bank 1.
(Refer to FUNCTIONAL DESCRIPTION for Simultaneous Operation.)
The standard device offers access times 80 ns, 90 ns and 120 ns, allowing operation of high-speed
microprocessors without the wait. To eliminate bus contention the device has separate chip enable (CE) , write
enable (WE) and output enable (OE) controls.
This device consists of 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 device is programmed by executing the program command sequence. This will invoke the Embedded
Program AlgorithmTM 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 about 0.5 seconds. Erase is
accomplished by executing the erase command sequence. This will invoke the Embedded Erase AlgorithmTM
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
the proper cell margin.
A sector is typically erased and verified in 1.0 second (if already completely 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 device 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 a program or erase cycle has been completed,
the device internally resets to the read mode.
The device 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 ProgramTM *2 Algorithm or Embedded EraseTM *2 Algorithm, the device is automatically reset to the
read mode and have erroneous data stored in the address locations being programmed or erased. These
locations need rewriting 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 EPROM and E2PROM experience to produce the highest levels
of quality, reliability, and cost effectiveness. The device memory electrically erases 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.

Address bits A21 to A11 = X = “H” or “L” for all address commands except or Program Address (PA) , Sector
Address (SA) , Bank Address (BA) and Sector Group Address (SPA) .
Bus operations are defined in Tables 2 and 3.
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 write pulse.
SA = Address of the sector to be erased. The combination of A21, A20, A19, A18, A17, A16, A15, A14, A13 and
A12 will uniquely select any sector.
BA = Bank Address. Address setted by A21, A20, A19 will select Bank A, Bank B, Bank C and Bank D.
RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the falling edge of write pulse.
SPA = Sector group address to be protected. Set sector group address and (A6, A3, A2, A1, A0) =
(0, 0, 0, 1, 0) .
SD = Sector group protection verify data. Output 01h at protected sector group addresses and output
00h at unprotected sector group addresses.
HRA = Address of the Hi-ROM area Word Mode : 000000h to 00007Fh
Byte Mode : 000000h to 0000FFh
HRBA = Bank Address of the Hi-ROM area (A21 = A20 = A19 = VIL)
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 A0, and A-1
Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.

Sector Group Protection
*1 : A-1 is for Byte mode.
*2 : Outputs 01h at protected sector group addresses and outputs 00h at unprotected sector group addresses.
*3 : When VID is applied to A9, both Bank 1 and Bank 2 are put into Autoselect mode, which makes simultaneous
operation unable to be executed. Consequently, specifying the bank address is not required. However, the bank
address needs to be indicated when Autoselect mode is read out at command mode, because then it becomes
possible to activate simultaneous operation.
*4 : At WORD mode, a read cycle at address (BA) 01h (at BYTE mode, (BA) 02h) outputs device code. When 227Eh
(at BYTE mode, 7Eh) is output, it indicates that two additional codes, called Extended Device Codes, will be
required. Therefore the system may continue reading out these Extended Device Codes at the address of (BA)
0Eh (at BYTE mode, (BA) 1Ch) , as well as at (BA) 0Fh (at BYTE mode, (BA) 1Eh) .

■ FUNCTIONAL DESCRIPTION
Simultaneous Operation
The device features functions that enable reading of data from one memory bank while a program or erase
operation is in progress in the other memory bank (simultaneous operation) , in addition to conventional features
(read, program, erase, erase-suspend read, and erase-suspend program) . The bank can be selected by bank
address (A21, A20, A19) with zero latency. The device consists of the following four banks :
Bank A : 8 × 8 KB and 15 × 64 KB; Bank B : 48 × 64 KB; Bank C : 48 × 64 KB; Bank D : 8 × 8 KB and 15 × 64 KB.
The device can execute simultaneous operations between Bank 1, a bank chosen from among the four banks,
and Bank 2, a bank consisting of the three remaining banks. (See Table 9.) This is what we call a “FlexBank”,
for example, the rest of banks B, C and D to let the system read while Bank A is in the process of program (or
erase) operation. However, the different types of operations for the three banks are impossible, e.g. Bank A
writing, Bank B erasing, and Bank C reading out. With this “FlexBank”, as described in Table 10, the system
gets to select from four combinations of data volume for Bank 1 and Bank 2, which works well to meet the system
requirement. The simultaneous operation cannot execute multi-function mode in the same bank. Table 11 shows
the possible combinations for simultaneous operation. (Refer to Figure 11 Bank-to-Bank Read/Write Timing
Diagram.)

Note : When multiple sector erase over several banks is operated, the system cannot read out of the bank to which
a sector being erased belongs. For example, suppose that erasing is taking place at both Bank A and Bank B,
neither Bank A nor Bank B is read out (they would output the sequence flag once they were selected.)
Meanwhile the system would get to read from either Bank C or Bank D.

Note: Bank 1 and Bank 2 are divided for the sake of convenience at Simultaneous Operation. Actually, the Bank
consists of 4 banks, Bank A, Bank B, BankC and Bank D. Bank Address (BA) meant to specify each of the
Banks.
Read Mode
The device has two control functions which are required 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.
Address access time (tACC) is equal to 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) . When reading out data without changing addresses after power-up,
it is necessary to input hardware reset or to change CE pin from “H” or “L”
Standby Mode
There are two ways to implement the standby mode on the device, one using both the CE and RESET pins, and
the other via the RESET pin only.
When using both pins, a CMOS standby mode is achieved with CE and RESET input 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 if 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 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 set high,
the device requires tRH as a wake-up time for output to be valid for read access.
During standby mode, the output is in the high impedance state, regardless of OE input.
24
MBM29DL640E80/90/12
Automatic Sleep Mode
Automatic sleep mode works to restrain power consumption during read-out of device data. It can be useful in
applications such as handy terminal, which requires low power consumption.
To activate this mode, the device automatically switches itself to low power mode when the device addresses
remain stable during access time of 150 ns. It is not necessary to control CE, WE and OE in this mode. In this
mode the current consumed is typically 1 µA (CMOS Level) .
During simultaneous operation, VCC active current (ICC2) is required.
Since the data are latched during this mode, the data are continuously read out. When the addresses are
changed, the mode is automatically canceled and the device reads the data for changed addresses.
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 and identifies its manufacturer and type.It is intended
for use by programming equipment for the purpose of automatically matching the device to be programmed with
its corresponding programming algorithm. This mode is functional over the entire temperature range of the device.
To activate this mode, the programming equipment must force VID on address pin A9. Three identifier bytes may
then be sequenced from the device outputs by toggling addresses. All addresses are DON’T CARES except A6,
A3, A2, A1 and A0 (A-1) . (See Tables 2 and 3.)
The manufacturer and device codes may also be read via the command register, for instances when the device
is erased or programmed in a system without access to high voltage on the A9 pin. The command sequence is
illustrated in Table 4. (Refer to Autoselect Command section.)
In the command Autoselect mode, the bank addresses BA; (A21, A20, A19) must point to a specific bank during
the third write bus cycle of the Autoselect command. Then the Autoselect data will be read from that bank while
array data can be read from the other bank.
In WORD mode, a read cycle from address 00h returns the manufacturer’s code (Fujitsu = 04h) . A read cycle
at address 01h outputs device code. When 227Eh is output, it indicates that two additional codes, called Extended
Device Codes will be required. Therefore the system may continue reading out these Extended Device Codes
at addresses of 0Eh and 0Fh. Notice that the above applies to WORD mode; the addresses and codes differ
from those of BYTE mode. (Refer to Table 5.1 and 5.2. )
In the case of applying VID on A9, since both Bank 1 and Bank 2 enter Autoselect mode, simultanous operation
cannot be executed.
Write
Device erasure and programming are accomplished via the command register. The contents of the register serve
as input to the internal state machine. The state machine output dictates 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.
25
MBM29DL640E80/90/12
Sector Group Protection
The device features hardware sector group protection. This feature will disable both program and erase operations in any combination of forty eight sector groups of memory. (See Table 7) . The user‘s side can use the
sector group protection using programming equipment. The device is shipped with all sector groups that are
unprotected.
To activate this mode, the programming equipment must force VID on address pin A9 and control pin OE, CE =
VIL and A6 = A3 = A2 = A0 = VIL, A1 = VIH. The sector group addresses (A21, A20, A19, A18, A17, A16, A15, A14, A13 and
A12) should be set to the sector to be protected. Tables 6.1 to 6.4 define the sector address for each of the one
hundred forty-two (142) individual sectors, and Table 7 defines the sector group address for each of the forty
eight (48) individual group 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 group addresses must be held constant during
the WE pulse. See Figures 18 and 26 for sector group protection waveforms and algorithms.
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 group addresses (A21, A20, A19, A18, A17, A16, A15, A14,
A13 and A12) while (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) will produce a logical “1” code at device output DQ0 for a
protected sector. Otherwise the device will produce “0” for unprotected sectors. In this mode, the lower order
addresses, except for A0, A1, A2, A3 and A6 are DON’T CARES. Address locations with A1 = VIL are reserved for
Autoselect manufacturer and device codes. A-1 requires applying to VIL on byte mode.
Whether the sector group is protected in the system can be determined by writing an Autoselect command.
Performing a read operation at the address location (BA) XX02h, where the higher order addresses (A21, A20,
A19, A18, A17, A16, A15, A14, A13, and A12) are the desired sector group address, will produce a logical “1” at DQ0
for a protected sector group. Note that the bank addresses (A21, A20, A19) must be pointing to a specific bank
during the third write bus cycle of the Autoselect command. Then the Autoselect data can be read from that
bank while array data can still be read from the other bank. To read Autoselect data from the other bank, it must
be reset to read mode and then write the Autoselect command to the other bank. See Tables 5.1 and 5.2 for
Autoselect codes.
Temporary Sector Group Unprotection
This feature allows temporary unprotection of previously protected sector groups of the device in order to change
data. The Sector Group Unprotection mode is activated by setting the RESET pin to high voltage (VID) . During
this mode, formerly protected sector groups can be programmed or erased by selecting the sector group addresses. Once the VID is taken away from the RESET pin, all the previously protected sector groups will be
protected again. Refer to Figures 19 and 27.
Extended Sector Group Protection
In addition to normal sector group protection, the device has Extended Sector Group Protection as extended
function. This function enables protection of the sector group by forcing VID on RESET pin and writes a command
sequence. Unlike conventional procedures, it is not necessary to force VID and control timing for control pins.
The only RESET pin requires VID for sector group protection in this mode. The extended sector group protection
requires VID on RESET pin. With this condition the operation is initiated by writing the set-up command (60h) in
the command register. Then the sector group addresses pins (A21, A20, A19, A18, A17, A16, A15, A14, A13 and A12)
and (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) should be set to the sector group to be protected (setting VIL for the other
addresses pins is recommended) , and an extended sector group protection command (60h) should be written.
A sector group is typically protected in 250 µs. To verify programming of the protection circuitry, the sector group
addresses pins (A21, A20, A19, A18, A17, A16, A15, A14, A13 and A12) and (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) should
be set a command (40h) should be written. Following the command write, a logical “1” at device output DQ0 will
produce a protected sector in the read operation. If the output is logical “0”, write the extended sector group
protection command (60h) again. To terminate the operation, it is necessary to set RESET pin to VIH. (Refer to
Figures 20 and 28.)
26
MBM29DL640E80/90/12
RESET
Hardware Reset
The 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 “tRP” 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 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. See Figure 14 for the timing diagram. Refer to Temporary Sector
Group Unprotection for additional functionality.
Boot Block Sector Protection
The Write Protection function provides a hardware method of protecting certain boot sectors without using VID.
This function is one of two provided by the WP/ACC pin.
If the system asserts VIL on the WP/ACC pin, the device disables program and erase functions in the two
outermost 8 Kbytes on both ends of boot sectors independently of whether those sectors are protected or
unprotected using the method described in “Sector Protection/Unprotection.”
(MBM29DL640E : SA0, SA1, SA140, and SA141)
If the system asserts VIH on the WP/ACC pin, the device reverts to whether the two outermost 8 Kbyte on both
ends of boot sectors were last set to be protected or unprotected. Sector protection or unprotection for these
four sectors depends on whether they were last protected or unprotected using the method described in “Sector
protection/unprotection.”
Accelerated Program Operation
The device offers accelerated program operation which enables programming in high speed. If the system asserts
VACC to the WP/ACC pin, the device automatically enters the acceleration mode and the time required for program
operation will reduce to about 60%. This function is primarily intended to allow high speed programming, so
caution is needed as the sector group will temporarily be unprotected.
The system would use a fast program command sequence when programming during acceleration mode.
Set command to fast mode and reset command from fast mode are not necessary. When the device enters the
acceleration mode, the device is automatically set to fast mode. Therefore, the present sequence could be used
for programming and detection of completion during acceleration mode.
Removing VACC from the WP/ACC pin returns the device to normal operation. Do not remove VACC from WP/
ACC pin while programming. See Figure 21.
27
MBM29DL640E80/90/12
■ COMMAND DEFINITIONS
Device operations are selected by writing specific address and data sequences into the command register. Some
commands require Bank Address (BA) input. When command sequences are input into a bank reading, the
commands have priority over the reading. Table 4 shows 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. Also the Program Suspend (B0h) and Program Resume (30h) commands are valid only while the
Program operation is in progress. Moreover, 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
In order to return from Autoselect mode or Exceeded Timing Limits (DQ5 = 1) to Read/Reset 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
in order 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 AC Read Characteristics and Timing Diagram for the specific timing parameters.
Autoselect Command
Flash memories are intended for use in applications where the local CPU alters memory contents. Therefore,
manufacture 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 higher 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.
The Autoselect command sequence is initiated first by writing two unlock cycles. This is followed by a third write
cycle that contains the bank address (BA) and the Autoselect command. Then the manufacture and device
codes can be read from the bank, and actual data from the memory cell can be read from another bank. The
higher order address (A21, A20, A19) required for reading out the manufacture and device codes demands the
bank address (BA) set at the third write cycle.
Following the command write, in WORD mode, a read cycle from address (BA) 00h returns the manufacturer’s
code (Fujitsu = 04h) . And a read cycle at address (BA) 01h outputs device code. When 227Eh was output, this
indicates that two additional codes, called Extended Device Codes will be required. Therefore the system may
continue reading out these Extended Device Codes at the address of (BA) 0Eh, as well as at (BA) 0Fh. Notice
that the above applies to WORD mode. The addresses and codes differ from those of BYTE mode. (Refer to
Table 5.1 and 5.2. )
The sector state (protection or unprotection) will be informed by address (BA) 02h for × 16 ( (BA) 04h for × 8) .
Scanning the sector group addresses (A21, A20, A19, A18, A17, A16, A15, A14, A13, and A12) while (A6, A3, A2, A1, A0)
= (0, 0, 0, 1, 0) will produce a logical “1” at device output DQ0 for a protected sector group. The programming
verification should be performed by verifying sector group protection on the protected sector. (See Tables 2 and 3.)
The manufacture and device codes can be read from the selected bank. To read the manufacture and device
codes and sector protection status from a non-selected bank, it is necessary to write the Read/Reset command
sequence into the register. Autoselect command should then be written into the bank to be read.
If the software (program code) for Autoselect command is stored in the Flash memory, the device and manufacture codes should be read from the other bank, which does not contain the software.
To terminate the operation, it is necessary to write the Read/Reset command sequence into the register. To
execute the Autoselect command during the operation, Read/Reset command sequence must be written before
the Autoselect command.
28
MBM29DL640E80/90/12
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) starts
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.
The system can determine the status of the program operation by using DQ7 (Data Polling) , DQ6 (Toggle Bit)
or RY/BY. The Data Polling and Toggle Bit must be performed at the memory location which is being programmed.
The automatic programming operation is completed when the data on DQ7 is equivalent to data written to this
bit at which time the device returns to the read mode and addresses are no longer latched (see Table 12,
Hardware Sequence Flags). Therefore, the device requires that a valid address to the device be supplied by the
system in this particular instance. Hence, Data Polling must be performed at the memory location which is being
programmed.
If hardware reset occurs during the programming operation, the data being written is not guaranteed.
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 from “0”s to “1”s.
Figure 22 illustrates the Embedded ProgramTM Algorithm using typical command strings and bus operations.
Program Suspend/Resume
The Program Suspend command allows the system to interrupt a program operation so that data can be read
from any address. Writing the Program Suspend command (B0h) during the Embedded Program operation
immediately suspends the programming. The Program Suspend command may also be issued during a programming operation while an erase is suspended. The bank addresses of sector being programmed should be
set when writing the Program Suspend command.
When the Program Suspend command is written during a programming process, the device halts the program
operation within 1 µs and updates the status bits.
After the program operation has been suspended, the system can read data from any address. The data at
program-suspended address is not valid. Normal read timing and command definitions apply.
After the Program Resume command (30h) is written, the device reverts to programming. The bank addresses
of sectors being suspended should be set when writing the Program Resume command. The system can
determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard program
operation. See “Write Operation Status” for more information.
The system may also write the Autoselect command sequence when the device in the Program Suspend mode.
The device allows reading Autoselect codes at the addresses within programming sectors, since the codes are
not stored in the memory. When the device exits the Autoselect mode, the device reverts to the Program Suspend
mode, and is ready for another valid operation. See “Autoselect Command Sequence” for more information.
The system must write the Program Resume command (address bits are “Bank Address”) to exit from the
Program Suspend mode and continue the programming operation. Further writes of the Resume command are
ignored. Another Program Suspend command can be written after the device has resumed programming.
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 all29
MBM29DL640E80/90/12
zero data pattern prior to electrical erase (Preprogram function) . The system is not required to provide any
controls or timings during these operations.
The system can determine the status of the erase operation by using DQ7 (Data Polling) , DQ6 (Toggle Bit) or
RY/BY. The chip erase begins on the rising edge of the last CE or WE, whichever happens first 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 the read mode.
Chip Erase Time; Sector Erase Time × All sectors + Chip Program Time (Preprogramming)
Figure 23 illustrates the Embedded EraseTM 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 CE or WE, whichever
happens later, while the command (Data = 30h) is latched on the rising edge of CE or WE, whichever happens
first. After time-out of “tTOW” from the rising edge of the last sector erase command, the sector erase operation
begins.
Multiple sectors may be erased concurrently by writing the six bus cycle operations on Table 4. This sequence
is followed by writes of the Sector Erase command to addresses in other sectors desired to be concurrently
erased. The time between writes must be less than “tTOW”. Otherwise, that command will not be accepted and
erasure will not start. It is recommended that processor interrupts be disabled during this time to guarantee such
a condition. The interrupts can reoccur after the last Sector Erase command is written. A time-out of “tTOW” from
the rising edge of last CE or WE, whichever happens first, will initiate the execution of the Sector Erase command
(s) . If another falling edge of CE or WE, whichever happens first occurs within the “tTOW” 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). Resetting the device once execution 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 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 141) .
Sector erase does not require the user to program the device before 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, the rest remain unaffected. The system is not required to provide any controls or timings during these
operations.
The system can determine the status of the erase operation by using DQ7 (Data Polling) , DQ6 (Toggle Bit) or
RY/BY.
The sector erase begins after the “tTOW” time-out from the rising edge of CE or WE, whichever happens first, 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 and Toggle Bit must be performed at
an address within any of the sectors being erased.
Multiple Sector Erase Time = [Sector Erase Time + Sector Program Time (Preprogramming) ] × Number of
Sector Erase
In case of multiple sector erase across bank boundaries, a read from the bank (read-while-erase) to which
sectors being erased belong cannot be performed.
Figure 23 illustrates the Embedded EraseTM Algorithm using typical command strings and bus operations.
Erase Suspend/Resume
The Erase Suspend command allows the user to interrupt Sector Erase operation and then reads data 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. Writing the Erase Suspend command (B0h) during the Sector
Erase time-out results in immediate termination of the time-out period and suspension of the erase operation.
30
MBM29DL640E80/90/12
Writing the Erase Resume command (30h) resumes the erase operation. The bank address of sector being
erased or erase-suspended should be set when writing the Erase Suspend or Erase Resume command.
When the Erase Suspend command is written during the Sector Erase operation, the device takes a maximum
of “tSPD” to suspend the erase operation. When the device has entered the erase-suspended mode, the
RY/BY output pin will be at Hi-Z 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. Reading successively 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, it is
the same as programming in the regular Program mode, except that the data must be programmed to sectors
that are not erase-suspended. Reading successively 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 within bank being erase-suspended.
To resume the operation of Sector Erase, the Resume command (30h) should be written to the bank being erase
suspended. 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
The device has a Fast Mode function. It dispenses with the initial two unclock cycles required in the standard
program command sequence by writing the Fast Mode command into the command register. In this mode, the
required bus cycle for programming consists of two bus cycles instead of four in standard program command.
Do not write erase command in this mode. The read operation is also executed after exiting from the fast mode.
To exit from this mode, it is necessary to write Fast Mode Reset command into the command register. The first
cycle must contain the bank address (see Figure 29) .The VCC active current is required even if CE = VIH during
Fast Mode.
(2) Fast Programming
During Fast Mode, programming can be executed with two bus cycle operation. The Embedded Program Algorithm is executed by writing program set-up command (A0h) and data write cycles (PA/PD) (see Figure 29) .
(3) CFI (Common Flash Memory Interface)
The CFI (Common Flash Memory Interface) specification outlines device and the 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 backward-compatible 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. The bank address
should be set when writing this command. Then the device information can be read from the bank, and data
from the memory cell can be read from the another bank. The higher order address (A21, A20, A19) required for
reading out the CFI Codes requires that the bank address (BA) be set at the write cycle. Following the command
write, a read cycle from specific address retrieves device information. Please note that output data of upper byte
(DQ15 to DQ8) is “0” in word mode (16 bit) read. Refer to CFI code table (Table 12) . To terminate operation, it is
necessary to write the read/reset command sequence into the register.
31
MBM29DL640E80/90/12
Hidden ROM (Hi-ROM) Region
The Hi-ROM feature provides a Flash memory region that the system may access through a new command
sequence. This is primarily intended for customers who wish to use an Electronic Serial Number (ESN) in the
device with the ESN protected against modification. Once the Hi-ROM region is protected, any further modification of that region becomes impossible. This ensures the security of the ESN once the product is shipped to
the field.
The Hi-ROM region is 256 bytes in length and is stored at the same address of the “outermost” 8 Kbyte boot
sector in Bank A. The device occupies the address of the byte mode 000000h to 0000FFh (word mode 000000h
to 00007Fh) . After the system has written the Enter Hi-ROM command sequence, the system may read the HiROM region by using the addresses normally occupied by the boot sector (particular area of SA0) . That is, the
device sends all commands that would normally be sent to the boot sector (particular area of SA0) to the HiROM region. This mode of operation continues until the system issues the Exit Hi-ROM command sequence,
or until power is removed from the device. On power-up, or following a hardware reset, the device reverts to
sending commands to the boot sector.
When reading the Hi-ROM region, either change addresses or change CE pin from “H” to “L”. The same procedure
should be taken (changing addresses or CE pin from “H” to “L”) after the system issues the Exit Hi-ROM command
sequence to read actual memory cell data.
Hidden ROM (Hi-ROM) Entry Command
The device has a Hidden ROM area with One Time Protect function. This area is to enter the security code and
to unable the change of the code once set. Programming is allowed in this area until it is protected. However,
once it gets protected, it is impossible to unprotect. Therefore, extreme caution is required.
The hidden ROM area is 256 bytes. This area is normally the “outermost” 8 Kbyte boot block area in Bank A.
Therefore, write the Hidden ROM entry command sequence to enter the Hidden ROM area. It is called Hidden
ROM mode when the Hidden ROM area appears.
Sectors other than the boot block area SA0 can be read during Hidden ROM mode. Read/program of the Hidden
ROM area is possible during Hidden ROM mode. Write the Hidden ROM reset command sequence to exit the
Hidden ROM mode. The bank address of the Hidden ROM should be set on the third cycle of this reset command
sequence.
In Hidden ROM mode, the simultaneous operation cannot be executed multi-function mode between the Hidden
ROM area and the Bank A.
Hidden ROM (Hi-ROM) Program Command
To program the data to the Hidden ROM area, write the Hidden ROM program command sequence during Hidden
ROM mode. This command is the same as the usual program command, except that it needs to write the
command during Hidden ROM mode. Therefore the detection of completion method is the same as in the past,
using the DQ7 data pooling, DQ6 toggle bit and RY/BY pin. You should pay attention to the address to be
programmed. If an address not in the Hidden ROM area is selected, the previous data will be deleted.
Hidden ROM (Hi-ROM) Protect Command
There are two methods to protect the Hidden ROM area. One is to write the sector group protect setup command
(60h) , set the sector address in the Hidden ROM area and (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) , and write the
sector group protect command (60h) during the Hidden ROM mode. The same command sequence may be
used because it is the same as the extension sector group protect in the past, except that it is in the Hidden
ROM mode and does not apply high voltage to the RESET pin. Please refer to “Function Explanation Extended
Sector Group Protection” for details of extension sector group protect setting.
The other method is to apply high voltage (VID) to A9 and OE, set the sector address in the Hidden ROM area
and (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) , and apply the write pulse during the Hidden ROM mode. To verify the
protect circuit, apply high voltage (VID) to A9, specify (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) and the sector address
in the Hidden ROM area, and read. When “1” appears on DQ0, the protect setting is completed. “0” will appear
on DQ0 if it is not protected. Apply write pulse again. The same command sequence could be used for the above
32
MBM29DL640E80/90/12
method because other than the Hidden ROM mode, it is the same as the sector group protect previously
mentioned. Refer to “Function Explanation Secor Group Protection” for details of the sector group protect setting.
Take note that other sector groups will be affected if an address other than those for the Hidden ROM area is
selected for the sector group address, so please be careful. Pay close attention that once it is protected, protection
CANNOT BE CANCELLED.
Write Operation Status
Detailed in Table 12 are all the status flags which can determine the status of the bank for the current mode
operation. The read operation from the bank which doesn’t operate Embedded Algorithm returns data of memory
cells. These bits offer a method for determining whether an Embedded Algorithm is properly completed. The
information on DQ2 is address-sensitive. This means that if an address from an erasing sector is consecutively
read, the DQ2 bit will toggle. However, DQ2 will not toggle if an address from a non-erasing sector is consecutively
read. This allows users to determine which sectors are in erase and which are not.
The status flag is not output from banks (non-busy banks) which do not execute Embedded Algorithms. For
example, a bank (busy bank) is executing an Embedded Algorithm. When the read sequence is [1] < busy bank
> , [2] < non-busy bank > , [3] < busy bank > , the DQ6 toggles in the case of [1] and [3]. In case of [2], the data
of memory cells are output. In the erase-suspend read mode with the same read sequence, DQ6 will not be
toggled in [1] and [3].
In the erase suspend read mode, DQ2 is toggled in [1] and [3]. In case of [2], the data of memory cell is output.

MBM29DL640E80/90/12
DQ7
Data Polling
The 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 device will produce a
complement of data last written to DQ7. Upon completion of the Embedded Program Algorithm, an attempt to
read the device will produce 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 device will produce a “1” on DQ7. The flowchart for Data Polling (DQ7) is shown in Figure 24.
For programming, the Data Polling is valid after the rising edge of the fourth write pulse in the four write pulse
sequences.
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 sequences. Data Polling must be performed at sector addresses of sectors being erased, not protected sectors. Otherwise the status may become invalid.
If a program address falls within a protected sector, Data Polling on DQ7 is active for approximately 1 µs, then
that bank returns to the read mode. After an erase command sequence is written, if all sectors selected for
erasing are protected, Data Polling on DQ7 is active for approximately 400 µs, then the bank returns to read mode.
Once the Embedded Algorithm operation is close to being completed, the device data pins (DQ7) may change
asynchronously while the output enable (OE) is asserted low. This means that device is driving status information
on DQ7 at one instant, and then that byte’s valid data at the next instant. Depending on when the system samples
the DQ7 output, it may read the status or valid data. Even if device has completed the Embedded Algorithm
operation and DQ7 has a valid data, data outputs on DQ0 to DQ6 may still be invalid. The valid data on DQ0 to
DQ7 will be read on successive read attempts.
The Data Polling feature is active only during the Embedded Programming Algorithm, Embedded Erase Algorithm
or sector erase time-out. (See Table 12.)
See Figure 9 for the Data Polling timing specifications and diagrams.
DQ6
Toggle Bit I
The device also features the “Toggle Bit I” as a method to indicate to the host system that the Embedded
Algorithms are in progress or completed.
During Embedded Program or Erase Algorithm cycle, successive attempts to read (OE toggling) data from the
busy bank 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
sequences. 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 sequences. The Toggle Bit I is active during the sector time out.
In programming, if the sector being written is protected, the toggle bit will toggle for about 1 µs and then stop
toggling with data unchanged. In erase, the device will erase all selected sectors except for protected ones. If
all selected sectors are protected, the chip will toggle the toggle bit for about 400 µs and then drop back into
read mode, having data kept remained.
Either CE or OE toggling will cause DQ6 to toggle. In addition, an Erase Suspend/Resume command will cause
DQ6 to toggle.
The system can use DQ6 to determine whether a sector is actively erased or is erase-suspended. When a bank
is actively erased (that is, the Embedded Erase Algorithm is in progress) , DQ6 toggles. When a bank enters the
Erase Suspend mode, DQ6 stops toggling. Successive read cycles during erase-suspend-program cause DQ6
to toggle.
To operate toggle bit function properly, CE or OE must be high when bank address is changed.
See Figure 10 for the Toggle Bit I timing specifications and diagrams.
34
MBM29DL640E80/90/12
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 “1”. This is a failure condition indicating that the program or erase cycle was
not successfully completed. Data Polling is only operating function of the device under this condition. The CE
circuit will partially power down device under these conditions (to approximately 2 mA) . 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 pre-erase. In
this case the device locks out and never completes the Embedded Algorithm operation. Hence, the system never
reads valid data on DQ7 bit and DQ6 never stop 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 device with the command sequence.
DQ3
Sector Erase Timer
After completion of the initial sector erase command sequence, sector erase time-out begins. DQ3 will remain
low until the time-out is completed. Data Polling and Toggle Bit are valid after the initial sector erase command
sequence.
If Data Polling or the Toggle Bit I indicates that a valid erase command has been written, DQ3 may be used to
determine whether the sector erase timer window is still open. If DQ3 is high (“1”) the internally controlled erase
cycle has begun. 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.
See Table 12 : Hardware Sequence Flags.
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 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 if the erase-suspend-read mode is in progress.
(DQ2 toggles while DQ6 does not.) See also Table 13 and Figure 12.
Furthermore DQ2 can also be used to determine which sector is being erased. At the erase mode, DQ2 toggles
if this bit is read from an erasing sector.
To operate toggle bit function properly, CE or OE must be high when bank address is changed.
Reading Toggle Bits DQ6/DQ2
Whenever the system initially begins reading toggle bit status, it must read DQ7 to DQ0 at least twice in a row
to determine whether a toggle bit is toggling. Typically a system would note and store the value of the toggle bit
after the first read. After the second read, the system would compare the new value of the toggle bit with the
first. If the toggle bit is not toggling, the device has completed the program or erase operation. The system can
read array data on DQ7 to DQ0 on the following read cycle.
35
MBM29DL640E80/90/12
However, if, after the initial two read cycles, the system determines that the toggle bit is still toggling, the system
also should note whether the value of DQ5 is high (see the section on DQ5) . If it is, the system should then
determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5
went high. If the toggle bit is no longer toggling, the device has successfully completed the program or erase
operation. If it is still toggling, the device did not complete the operation successfully, and the system must write
the reset command to return to reading array data.
The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not
gone high. The system may continue to monitor the toggle bit and DQ5 through successive read cycles, determining the status as described in the previous paragraph. Alternatively, it may choose to perform other system
tasks. In this case, the system must start at the beginning of the algorithm when it returns to determine the
status of the operation. (Refer to Figure 25.)

RY/BY
Ready/Busy
The device provides a RY/BY open-drain output pin as a way to indicate to the host system that Embedded
Algorithms are either in progress or have been completed. If output is low, the device is busy with either a program
or erase operation. If output is high, the device is ready to accept any read/write or erase operation. If the device
is placed in an Erase Suspend mode, RY/BY output will be high.
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 RESET pulse. Refer to Figures 13 and 14 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.
Byte/Word Configuration
BYTE pin selects byte (8-bit) mode or word (16-bit) mode for the device. When this pin is driven high, the device
operates in word (16-bit) mode. Data is read and programmed at DQ15 to DQ0. When this pin is driven low, the
device operates in byte (8-bit) mode. In 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 DQ15 to DQ8 bits are ignored. Refer to Figures 15, 16 and 17 for the timing diagram.
Data Protection
The device is designed to offer protection against accidental erasure or programming caused by spurious system
level signals that may exist during power transitions. During power-up, the device automatically resets the internal
state machine in Read mode. Also, with its control register architecture, alteration of memory contents only
occurs after successful completion of specific multi-bus cycle command sequences.
The device also incorporates several features to prevent inadvertent write cycles resulting from VCC power-up
and power-down transitions or system noise.
36
MBM29DL640E80/90/12
Low VCC Write Inhibit
To avoid initiation of a write cycle during VCC power-up and power-down, a write cycle is locked out for VCC less
than VLKO (Min.) . If VCC < VLKO, the command register is disabled and all internal program/erase circuits are
disabled. Under this condition, the device will reset to the read mode. Subsequent writes will be ignored until
the VCC level is greater than VLKO. It is the user’s responsibility to ensure that the control pins are logically correct
to prevent unintentional writes when VCC is above VLKO (Min.) .
If the Embedded Erase Algorithm is interrupted, the intervened erasing sector (s) is (are) not valid.
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.
