The MBM29L V320TE/BE is 32 M-bit, 3.0 V-only Flash memory organized as 4 M bytes of 8 bits each or 2 M words
of 16 bits each. The device is offered in a 48-pin TSOP (I) and 63-ball FBGA packages. This device is designed
to be programmed in-system with the standard system 3.0 V V
for write or erase operations. The device can also be reprogrammed in standard EPROM programmers.
The standard device off ers access times 80 ns, 90 ns and 100 ns, allo wing operation of high-speed microprocessors without wait state. To eliminate bus contention the device has separate chip enable(CE

The device 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 er ase operations. Reading data out of the de vice 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 Algorithm which is an internal algorithm that automatically times the program pulse widths and verifies
proper cell margin. Typically, each sector can be programmed and verified in about 0.5 seconds. Erase is
accomplished by ex ecuting the erase command sequence. This will inv oke the Embedded Erase Algorithm which
is an internal algorithm that automatically preprograms the array if it is not already programmed bef ore ex ecuting
the erase operation. During erase, the device automatically time the erase pulse widths and verify 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 f eatures single 3.0 V po w er supply operation for both read and write functions. Internally generated
and regulated voltages are provided for the program and erase operations. A low V
inhibits write operations on the loss of power. The end of program or erase is detected by Data
by the Toggle Bit feature on DQ
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 inter nal state machine is then reset to the read
mode. The RESET
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.

and RESET pins; the
Under this condition the current consumed is less than 5 µA Max During Embedded Algorithm operation, V
active current (ICC2) is required ev en 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 V SS± 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 t
RH as wake up time for outputs to be valid for read access.
In the standby mode the outputs are in the high impedance state, independently of the OE input.
3.Automatic Sleep Mode
There is a function called automatic sleep mode to restrain power consumption during read-out of the device
data. This mode can be useful in the application such as a handy terminal which requires low power consumption.
To activate this mode, the device automatically switches themselves 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 on the mode.
Under the mode, the current consumed is typically 1 µA (CMOS Level) .
CC
During simultaneous operation, V
CC active current (ICC2) is required.
Since the data are latched during this mode, the data are read-out continuously. If the addresses are changed,
the mode is canceled automatically, and the device read the data for changed addresses.
4.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.
5.Autoselect
The autoselect mode allows the reading out of a binary code from the device and will identify its manufacturer
and type. This mode is intended for use by programming equipment for the purpose of automatically matching
the 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 V

A

panded Autoselect Code Table“ in ■DEVICE BUS OPERATIONS.)
6.Write
The device erasure and progr amming are accomplished via the command register. The contents of the register
serve as inputs to the internal state machine. The state machine outputs dictate the function of the device.
The command register itself does not occupy any addressab le 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
falling edge of WE
or CE, whichever happens later; while data is latched on the rising edge of WE or CE,
to VIL, while CE is at VIL and OE is at VIH. Addresses are latched on the
whichever happens first. Standard microprocessor write timings are used.
See “Read Only Operation Characteristics” in ■AC CHARACTERISTICS for specific timing parameters.
7.Sector Group Pr otection
The device f eatures hardware sector group protection. This feature will disable both program and erase operations in any combination of twenty five sector groups of memory. (See “Sector Group Address Tables
(MBM29L V320TE/BE)” in ■FLEXIBLE SECTOR-ERASE ARCHITECTURE). The sector g roup protection feature
is enabled using programming equipment at the user’s site. The device is shipped with all sector groups unprotected.

■FLEXIBLE SECTOR-ERASE ARCHITECTURE define the sector address for each of the seventy one (71)
individual sectors, and “Sector Group Address Tables (MBM29LV320TE/BE)” in ■FLEXIBLE SECT OR-ERASE
ARCHITECTURE define the sector group address for each of the twenty five (25) individual group sectors.
Programming of the protection circuitry begins on the falling edge of the WE
rising edge of the same. Sector group addresses must be held constant during the WE
pulse and is terminated with the
pulse. See “14. Sector
Group Protection Timing Diagram” in ■TIMING DIAGRAM and “5. Sector Group Protection Algorithm” in ■FLOW
CHART for sector group protection waveforms and algorithm.
To verify programming of the protection circuitry, the programming equipment must force V
ID on address pin A9
with CE and OE at VIL and WE at VIH. Scanning the sector group addresses (A20, A19, A18, A17, A16, A15, A14, A13,
and A
12) while (A6, A1, A0) = (0, 1, 0) will produce a logical “1” code at device output DQ0 f or a protected sector.
Otherwise the device will produce “0” for unprotected sector. In this mode, the lower order addresses, except
for A
0, A1, and A6 are DON’T CARES. Address locations with A1= VIL are reserved for Autoselect manufacturer
and device codes. A
-1 requires to apply to VIL on byte mode.
It is also possible to determine if a sector group is protected in the system by writing an Autoselect command.

A
16, A15, A14, A13, and A12) are the desired sector group address will produce a logical “1” at DQ0 for a protected
sector group. See “MBM29LV320TE/BE Sector Group Protection V erify A utoselect Codes T ab le” and “Expanded
Autoselect Code Table” in ■DEVICE BUS OPERATIONS for Autoselect codes.
8.Temporary Sector Group Unprotection
This feature allows temporary unprotection of previously protected sector g roups 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 V
ID is taken away from the RESET pin, all the previously protected sector groups will be
protected again. See “15. Temporary Sector Group Unprotection Timing Diagram” in ■TIMING DIAGRAM and
“6. Temporary Sector Group Unprotection Algorithm” in ■FLOW CHART.

9.Extended Sector Group Protection
In addition to normal sector group protection, the device has Extended Sector Group Protection as extended
function. This function enables to protect sector group by forcing V
ID on RESET pin and write a command
sequence. Unlike conv entional procedure, it is not necessary to force VID and control timing f or control pins. The
only RESET
requires V
into the command register. Then, the sector group addresses pins (A
pin requires VID for sector group protection in this mode. The extended sector group protection
ID on RESET pin. With this condition, the operation is initiated by writing the set-up command (60h)
20, A19, A18, A17, A16, A15, A14, A13 and A12)
and (A6, A1, A0) = (0, 1, 0) should be set to the sector group to be protected (recommend to set VIL for the other
addresses pins) , and write extended sector group protection command (60h) . A sector group is typically
protected in 250 µs. To verify programming of the protection circuitry, the sector group addresses pins (A
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 DQ
0 will produce for protected sector in the read operation. If
the output is logical “0”, please repeat to write extended sector group protection command (60h) again. To
terminate the operation, it is necessary to set RESET
pin to VIH. (See “16. Extended Sector Group Protection
Timing Diagram” in ■TIMING DIAGRAM and “7. Extended Sector Group Protection Algorithm” in ■FLOW
CHART.)
10. RESET

be kept low (V

or erase operation, the data at that particular location will be corrupted. Please note that the RY/BY
should be ignored during the RESET
pulse. See “10. RESET, RY/BY Timing Diagram” in ■TIMING DIAGRAM

for the timing diagram. See “8. Temporary Sector Group Unprotection” for additional functionality.
11. Boot Block Sector Protection
20, A19,
The Write Protection function provides a hardware method of protecting certain boot sectors without using V
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 K byte boot sectors independently of whether those sectors are protected or unprotected using
the method described in “Sector Protection/Unprotection”. The two outermost 8 K byte boot sectors are the two
sectors containing the lowest addresses in a bottom-boot-configured device, or the two sectors containing the
highest addresses in a top-boot-congfigured device.
(MBM29LV320TE : SA69 and SA70, MBM29LV320BE : SA0 and SA1)
If the system asserts V
IH on the WP/ACC pin, the device reverts to whether the two outermost 8 K byte boot
sectors were last set to be protected or unprotected. That is, sector protection or unprotection for these two
sectors depends on whether they were last protected or unprotected using the method described in “Sector
protection/unprotection”.
12. Accelerated Program Operation
The device offers accelerated program operation which enables the programming in high speed. If the system
asserts V
ACC
to the WP/ACC pin, the device automatically enters the acceleration mode and the time required
for program oper ation will reduce to about 60%. This function is primarily intended to allow high speed program,
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 necessar y. When the device enters the
acceleration mode, the de vice automatically set to fast mode. Therefore, the pressent sequence could be used
for programming and detection of completion during acceleration mode.
Removing V
ACC
from the WP/ACC pin returns the device to normal operation. Do not remove V
ACC
from WP/
ACC pin while programming. See “17. Accelerated Program Timing Diagram” in ■TIMING DIAGRAM.

COMMAND DEFINITIONS
■
80/90/10
The device operations are selected b y writing specific address and data sequences into the command register .
Writing incorrect address and data values or writing them in the improper sequence will reset the device to the
read mode. “MBM29LV320TE/BE Command Definitions Table” in ■DEVICE BUS OPERATIONS 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 DQ
7 to DQ0 and DQ15 to DQ8 bits are ignored.
1.Read/Reset Command
In order to return from Autoselect mode or Exceeded Timing Limits (DQ
5= 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 memor y. The device remain enabled for reads until the
command register contents are altered.
The device will automatically powe r-up in the Read/Reset state. In this case, a command sequence is not required
to read data. Standard microprocessor read cycles will retrieve array data. This default value ensures that no
spurious alteration of the memory content occurs during the power transition. See “■AC CHARACTERISTICS”
for the specific timing parameters.
2.Autoselect Command
Flash memories are intended for use in applications where the local CPU alters memory contents. As such,
manufacture and device codes must be accessible while the device resides in the target system. PROM programmers typically access the signature codes by raising A
9 to a high voltage. How ever , multiple xing high voltage
onto the address lines is not generally desired system design practice.
The device contains an A utoselect command operation to supplement tr aditional PR OM programming method-
ology. The operation is initiated by writing the Autoselect command sequence into the command register.
Following the command write, a read cycle from address (XX) 00h retrieves the manufacture code of 04h. A
read cycle from address (XX) 01h for ×16 ( (XX) 02h f or ×8) returns the device code. A read cycle from address
(XX) 03h for ×16 ( (XX) 06h f or ×8) returns the extended de vice code . (See “MBM29LV320TE/BE Sector Group
Protection Verify Autoselect Codes Table” and “Expanded Autoselect Code Table” in ■DEVICE BUS OPERATIONS.)
The sector state (protection or unprotection) will be informed by address (XX) 02h for ×16 ( (XX) 04h for ×8) .
Scanning the sector group addresses (A
will produce a logical “1” at device output DQ
20, A19, A18, A17, A16, A15, A14, A13, and A12) while (A6, A1, A0) = (0, 1, 0)
0 for a protected sector group . The programming v erification should
be performed by verify sector group protection on the protected sector. (See “MBM29LV320TE/BE User Bus
Operations Tables (BYTE
= VIH and BYTE = VIL)” in ■DEVICE BUS OPERATIONS.)
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, writing Read/Reset command sequence must precede
the Autoselect command.
3.Byte/Word Programming
The device is programmed on a b yte-by-byte (or word-by-w ord) basis. Programming is a four b us cycle operation.
There are two “unlock” write cycles. These are f ollow ed by the prog ram set-up command and data write cycles.
Addresses are latched on the falling edge of CE
rising edge of CE
or WE, whichever happens first. The rising edge of CE or WE (whiche ver happens first) begins
or WE, whichever happens later and the data is latched on the
programming. Upon ex ecuting 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 DQ
or RY/BY
. The Data Polling and Toggle Bit m ust be performed at the memory location which is being programmed.

bit at which time the device return to the read mode and addresses are no longer latched. (See “Hardware
Sequence Flags Table”.) Therefore, the device requires that a valid address to the device be supplied by the
system at this particular instance of time. Hence, Data
Polling m ust be perf ormed at the memory location which
is being programmed.
Any commands written to the chip during this period will be ignored. If hardware reset occurs during the pro-
gramming operation, it is impossible to guarantee the data are being written.
Programming is allowed in any sequence and across sector boundar ies. 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.
“1. Embedded Program
TM
Algorithm” in ■FLOW CHART illustrates the Embedded ProgramTM Algorithm using
typical command strings and bus operations.
4.Chip Erase
Chip erase is a six bus cycle operation. There are two “unlock” wr ite 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 de vice prior to erase. Upon ex ecuting the Embedded Erase
Algorithm command sequence the device will automatically program and v erify 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 system can determine the status of the erase operation by using DQ
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 DQ
7 is “1” (See “12. Write Operation Status”.) at which time the
7 (Data Polling) , DQ6 (Toggle Bit) , or
device returns to read the mode.

5.Sector Erase
Sector erase is a six bus cycle operation. There are two “unloc k” write cycles. These are followed by writing the
“set-up” command. Two more “unlock” write cycles are then follo wed b y the Sector Erase command. The sector

Multiple sectors may be erased concurrently by wr iting the six bus cycle operations on “MBM29LV320TE/BE
Command Definitions Table” in ■DEVICE BUS OPERATIONS. 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 “t
TOW” otherwise that command will not be accepted and erasure will not star t. 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 “t

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 execution has begun will corrupt
the data in the sector. In that case, restar t the erase on those sectors and allow them to complete. (See “12.
Write Operation Status” for Sector Erase Timer operation.) Loading the sector erase buffer may be done in any
sequence and with any number of sectors (0 to 70) .
Sector erase does not require the user to program the de vice prior to erase. The device automatically program

Algorithm” in ■FLOW CHART illustrates the Embedded Er aseTM Algorithm using typical
command strings and bus operations.
6.Erase Suspend/Resume
The Erase Suspend command allows the user to interrupt a Sector Erase operation and then perf orm data reads
from or programs to a sector not being erased. This command is applicable ONLY during the Sector Erase
operation which includes the time-out period for sector erase. The Erase Suspend command will be ignored if
written during the Chip Erase operation or Embedded Program Algorithm. Writting the Erase Suspend command
(B0h) 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 (30h) resumes the erase operation. The addresses are “DON’T CARES”
when writing the Erase Suspend or Erase Resume command.
When the Erase Suspend command is written during the Sector Erase operation, the device will take a maximu m
of “t
SPD” 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 DQ
6 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 def aults to the er ase-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. Successiv ely reading from the er ase-suspended sector while the
device is in the erase-suspend-read mode will cause DQ
2 to toggle. (See “17. 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 Progr am mode except that the data must be
programmed to sectors that are not erase-suspended. Successively reading from the erase-suspended sector
while the device is in the erase-suspend-progr am mode will cause DQ

output pin, Data polling of DQ7 or by the Toggle Bit I (DQ6) which
7 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.
7.Extended Command
(1) Fast Mode
The device has Fast Mode function. This mode dispenses with the initial two unclock cycles required in the
standard program command sequence by writing F ast Mode command into the command register . In this mode,
the required bus cycle for prog ramming is tw o 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. (See “8. Embedded
Program
TM
Algorithm for F ast Mode” in ■FLOW CHAR T .) The VCC active current is required ev en CE = VIH during
Fast Mode.
28
MBM29LV320TE/BE
(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) . (See “8.
Embedded Program
(3) CFI (Common Flash Memory Interface)
The CFI (Common Flash Memory Interface) specification outlines device and host system software interrogation
handshake which allows specific ve ndor-specified software algorithms to be used for entire families of device.
This allows device-independent, JEDEC ID-independent, and forward-and backward-compatible software support for the specified flash device families. See “Common Flash Memory Interface Code Table” in ■FLEXIBLE
SECTOR-ERASE ARCHITECTURE for details.
The operation is initiated by writing the query command (98h) into the command register. F ollowing the command
write, a read cycle from specific address retrives device inf ormation. Please note that output data of upper byte
(DQ
15 to DQ8) is “0” in word mode (16 bit) read. See “Common Flash Memory Interface Code T able” in ■FLEXIBLE
SECTOR-ERASE ARCHITECTURE. To terminate operation, it is necessar y to wr ite the read/reset command
sequence into the register. (See “Common Flash Memory Interface Code Table” in ■FLEXIBLE SECTORERASE ARCHITECTURE.)
8.Hidden ROM (Hi-ROM ) Region
The Hi-ROM feature provides a Flash memor y 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 is impossible. This ensures the security of the ESN once the product is shipped to the field.
TM
Algorithm for Fast Mode” in ■FLOW CHART.)
80/90/10
The Hi-ROM region is 256 bytes in length and is stored at the same address of the “outermost” 8 K byte boot
sector. The MBM29LV320TE occupies the address of the byte mode 3FFFC0h to 3FFFFFh (word mode
1FFFE0h to 1FFFFFh) and the MBM29LV320BE type occupies the address of the byte mode 000000h to
000080h (word mode 000000h to 000040h) . After the system has written the Enter Hi-ROM command sequence,
the system may read the Hi-ROM region by using the addresses normally occupied by the boot sector. That is,
the device sends all commands that would normally be sent to the boot sector to the Hi-ROM 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.
9.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. Program/erase is possib le in this area until it is protected. Ho w ever,
once it is protected, it is impossible to unprotect, so please use this with caution.
Hidden ROM area is 256 byte and in the same address area of “outermost” 8 K byte boot bloc k. Theref ore, write
the Hidden ROM entry command sequence to enter the Hidden ROM area. It is called as Hidden ROM mode
when the Hidden ROM area appears.
Sector other than the boot block area could 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.
10. Hidden ROM (Hi-ROM) Program Command
T o program the data to the Hidden R OM area, write the Hidden ROM program command sequence during Hidden
ROM mode. This command is the same as the program command in usual e xcept to write the command during
Hidden ROM mode. Therefore the detection of completion method is the same as in the past, using the DQ
data poling, DQ6 toggle bit and RY/BY pin. Need to pa y attention to the address to be programmed. If the address
other than the Hidden ROM area is selected to program, data of the address will be changed.
7
Please note that the sector erase command is prohibited during Hidden ROM mode. If the sector erase command
is appeared in this mode, data of the address will be erased.
29
MBM29LV320TE/BE
80/90/10
11. 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 (A
6
, A1, A0) = (0,1,0) , and write the sector group
protect command (60h) during the Hidden ROM mode. The same command sequence could 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 it
does not apply high voltage to RESET
pin. Please see “9. Extended Sector Group Protection” in ■FUNCTIONAL
DESCRIPTION for details of extention sector group protect setting.
The other is to apply high voltage (V
1
A
, A0) = (0,1,0) , and apply the write pulse during the Hidden ROM mode. To verify the protect circuit, apply
high voltage (V
ID
) to A9, specify (A6, A1, A0) = (0,1,0) and the sector address in the Hidden ROM area, and
read. When “1” appears on DQ
ID
) to A9 and OE, set the sector address in the Hidden ROM area and (A6,
0, the protect setting is completed. “0” will appear on DQ0 if it is not protected.
Please apply write pulse agian. The same command sequence could be used for the above method because
other than the Hidden ROM mode, it is the same as the sector group protect in the past. Please see “7. Sector
Group Protection” in ■FUNCTIONAL DESCRIPTION for details of the sector group protect setting.
Other sector group will be effected if the address other than those f or Hidden ROM area is selected f or the sector
group address, so please be carefull. Once it is protected, protection can not be cancelled, so please pay the
closest attention.
12. Write Operation Status
Details in “Hardware Sequence Flags Table” are all the status flags that can be used to check the status of the
device for current mode operation. Dur ing sector erase, the part provides the status flags automatically to the
I/O ports. The information on DQ
consecutively read, then the DQ
2 is address sensitive. This means that if an address from an erasing sector is
2 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.
Once erase suspend is entered, address sensitivity still applies. If the address of a non-erasing sector (that is,
one available for read) is provided, then stored data can be read from the device. If the address of an erasing
sector (that is, one unavailable for read) is applied, the device will output its status bits.

For programming, the Data

For chip erase and sector erase, the Data Polling is valid after the rising edge of the sixth write pulse in the six

During programming, the Toggle Bit I is valid after the rising edge of the fourth write pulse in the four write pulse
sequence. For chip erase and sector er ase, the Toggle Bit I is valid after the rising edge of the sixth write pulse
in the six write pulse sequence. The Toggle Bit I is active during the sector time out.
In program operation, 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 operation, the device will er ase all selected sectors e xcept f or ones
that are protected. If all selected sectors are protected, chip will toggle the toggle bit for about 400 µs and then
drop back into read mode, having data unchanged.
Either CE

The DQ

case the device locks out and never complete the Embedded Algorithm operation. Hence, the system never
read valid data on DQ
7 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 f ailure condition since device was incorrectly used. If
this occurs, reset device with command sequence.

Sector Erase Timer
After completion of the initial sector erase command sequence the sector erase time-out will begin. 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 Toggle Bit I indicates 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 DQ
3 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
DQ
3 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 “Hardware Sequence Flags Table”.
17. DQ
2
Toggle Bit II
This toggle bit II, along with DQ
6, 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 DQ
2 to toggle during the Embedded Erase Algorithm. If the
device is in the erase-suspended-read mode, successiv e reads from the erase-suspended sector will cause DQ
to toggle. When the device is in the erase-suspended-program mode, successive reads from the byte address
of the non-erase suspended sector will indicate a logic “1” at the DQ
2 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 DQ
7, is summarized
as follows :
For example, DQ
(DQ
2 toggles while DQ6 does not.) See also “T oggle Bit Status Table” and “8. DQ2 vs DQ6” in ■TIMING DIAGRAM.
Furthermore, DQ

2 toggles if this bit is read from an erasing sector.

/DQ
Whenever the system initially begins reading toggle bit status , it m ust 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, this indicates that the device has completed the program or er ase operation.
The system can read array data on DQ
7 to DQ0 on the following read cycle.
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 DQ
again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ
5 is high (see “15. DQ5”) . If it is the system should then determine
5 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.

19. RY/BY
Ready/Busy
The device 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 output is low , the device is b usy with either a program
or erase operation. If output is high, the device is ready to accept any read/write or erase operation. When the
RY/BY
pin is low, the device will not accept any additional program or erase commands. If the device is placed
in an Erase Suspend mode, RY/BY
output will be high.

21. Data Protection
The device is designed to off er protection against accidental erasure or programming caused by spurious system
level signals that may exist during power transitions. During power up de vice automatically resets internal state
machine in Read mode. Also, with its control register architecture, alteration of memor y contents only occurs
after successful completion of specific multi-bus cycle command sequences.
The device also incorporates several features to prevent inadver tent wr ite cycles resulting from V
CC power-up
and power-down transitions or system noise.

prevent unintentional writes when V

If Embedded Erase Algorithm is interrupted, there is possibility that the erasing sector (s) cannot be used.
23. Write Pulse “Glitch” Protection
Noise pulses of less than 3 ns (Typ) on OE

24. Logical Inhibit
Writing is inhibited by holding any one of OE

must be a logical zero while OE is a logical one.
25. Power-Up Write Inhibit
Power-up of the device with WE

The internal state machine is automatically reset to the read mode on power-up.
