■ DESCRIPTION

The MBM29PL32TM/BM is a 32M-bit, 3.0 V-only Flash memory organized as 4M bytes by 8 bits or 2M words by

16 bits. The MBM29PL32TM/BM is offered in 48-pin TSOP(1) and 48-ball FBGA. The device is designed to be

programmed in-system with the standard 3.0 V V^CCsupply. 12.0 V VPP and 5.0 V VCC are not required for write or

erase operations. The devices can also be reprogrammed in standard EPROM programmers.

(Continued)

The standard MBM29PL32TM/BM offers access times of 90 ns, allowing operation of high-speed microproces-

sors without wait states. To eliminate bus contention the devices have separate chip enable (CE), write enable

(WE), and output enable (OE) controls.

The MBM29PL32TM/BM supports command set compatible with JEDEC single-power-supply EEPROMS stan-

dard. Commands are written into the command register. The register contents serve as input to an internal state-

machine which controls the erase and programming circuitry. Write cycles also internally latch addresses and

data needed for the programming and erase operations. Reading data out of the devices is similar to reading

from 5.0 V and 12.0 V Flash or EPROM devices.

The MBM29PL32TM/BM is programmed by executing the program command sequence. This will invoke the

Embedded Program Algorithm^TMwhich is an internal algorithm that automatically times the program pulse widths

and verifies proper cell margin. Erase is accomplished by executing the erase command sequence. This will

invoke the Embedded Erase Algorithm^TMwhich is an internal algorithm that automatically preprograms the array

if it is not already programmed before executing the erase operation. During erase, the device automatically

times the erase pulse widths and verifies proper cell margin.

The device also features a sector erase architecture. The sector mode allows each sector to be erased and

reprogrammed without affecting other sectors. All sectors are 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 V^CCdetector 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. Once the end of a program or erase cycle has been completed, the devices

internally return to the read mode.

Fujitsu Flash technology combines years of Flash memory manufacturing experience to produce the highest

levels of quality, reliability, and cost effectiveness. The devices electrically erase all bits within a sector simulta-

neously via hot-hole assisted erase. The words are programmed one word at a time using the EPROM program-

ming mechanism of hot electron injection.

■ FUNCTIONAL DESCRIPTION

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, 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, V^CCactive

current (I^CC2) is required even when CE = “H”. The device can be read with standard access time (tCE) from either

of these standby modes.

When using the RESET pin only, 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 t^RHas 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.

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 switch themselves to low power mode when the device addresses

remain stable after t^ACC+ 30 ns from data valid. It is not necessary to control CE, WE, and OE in this mode. The

current consumed is typically 1 μA (CMOS Level).

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 read-out the data for changed addresses.

Autoselect

The Autoselect mode allows 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.

To activate this mode, the programming equipment must force V^IDon address pin A9. Two identifier bytes may

then be sequenced from the devices outputs by toggling A⁰. All addresses can be either High or Low except A6,

A³,A2,A1 and A0. See “MBM29PL32TM/BM User Bus Operations (Word Mode : BYTE = VIH)” and

“MBM29PL32TM/BM User Bus Operations (Byte Mode : BYTE = VIL)” in ■DEVICE BUS OPERATION.

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 A⁹pin. The command sequence is

illustrated in “MBM29PL32TM/BM Standard Command Definitions” in ■DEVICE BUS OPERATION.Refer to

Autoselect Command section.

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 “Sector Group Protection Verify Autoselect Codes” in ■DEVICE BUS OPERATION.

Read Mode

The device has two control functions required to obtain data at the outputs. CE is the power control and used

for a device selection. OE is the output control and used to gate data to the output pins.

Address access time (t^ACC) is equal to the delay from stable addresses to valid output data. The chip enable

access time (t^CE) 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 t^ACC-tOE time.) When reading out a data without changing addresses after

power-up, input hardware reset or to change CE pin from “H” or “L”.

MBM29PL32TM/BM90/10

Page Mode Read

The device is capable of fast read access for random locations within limited address location called Page. The

Page size of the device is 8 bytes / 4 words, within the appropriate Page being selected by the higher address

bits A²⁰to A2 and the address bits A1 to A0 in Word mode ( A1 to A-1 in Byte mode) determining the specific word

within that page. This is an asynchronous operation with the microprocessor supplying the specific word location.

The initial page access is equal to the random access (t^ACC) and subsequent Page read access (as long as the

locations specified by the microprocessor fall within that Page) is equivalent to the page address access time

(t^PACC). Here again, CE selects the device and OE is the output control and should be used to gate data to the

output pins if the device is selected. Fast Page mode, accesses are obtained by keeping A²⁰to A2 constant and

changing A¹and A0 in Word mode ( A1 to A-1 in Byte mode ) to select the specific word within that Page.

Output Disable

With the OE input at logic high level (VIH), output from the devices are disabled. This may cause the output pins

to be in a high impedance state.

Write

Device erasure and programming are accomplished via the command register. The contents of the register serve

as inputs to the internal state machine. The state machine outputs dictate the device function.

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 com-

mand 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 starts later; while data is latched on the rising edge of WE or CE, whichever

starts first. Standard microprocessor write timings are used.

Refer to AC Write Characteristics and the Erase/Programming Waveforms for specific timing parameters.

Sector Group Protection

The device features hardware sector group protection. This feature will disable both program and erase opera-

tions in any combination of thirty two sector groups of memory.See “Sector Group Address Table

(MBM29PL32TM)” and “Sector Group Address Table (MBM29PL32BM)” in ■DEVICE BUS OPERATION. 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 it, the programming equipment must force V^IDon address pin A9 and control pin OE, CE = VIL and

A⁶= A3 = A2 = A0 = VIL, A1 = VIH. The sector group addresses (A20, A19, A18, A17, A16, A15, A14, A13, and A12) should

be set to the sector to be protected. “Sector Address Table (MBM29PL32TM)” and “Sector Address Table

(MBM29PL32BM)” in ■DEVICE BUS OPERATION defines the sector address for each of the seventy-one (71)

individual sectors, and “Sector Group Address Table (MBM29PL32TM)” and “Sector Group Address Table

(MBM29PL32BM)” in ■DEVICE BUS OPERATION defines the sector group address for each of the twenty-four

(24) 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 “Sector Group Protection Timing Diagram” in ■SWITCHING WAVEFORMS and “Sector Group

Protection Algorithm” in ■FLOW CHART for sector group protection timing diagram and algorithm.

To verify programming of the protection circuitry, the programming equipment must force V^IDon 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 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 can be either High or Low. Address locations with A1 = VIL are reserved

for Autoselect manufacturer and device codes. A^-1requires applying 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.

Performing a read operation at the address location XX02h, where the higher order addresses(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. See “Sector Group Protection Verify Autoselect Codes” in ■DEVICE BUS OPERATION for Au-

toselect codes.

MBM29PL32TM/BM90/10

Temporary Sector Group Unprotection

This feature allows temporary unprotection of previously protected sector groups of the devices 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^IDis taken away from the RESET pin, all the previously protected sector groups will be

protected again. Refer to “Temporary Sector Group Unprotection Timing Diagram” in ■SWITCHING WAVE-

FORMS and “Temporary Sector Group Unprotection Algorithm” in ■FLOW CHART.

Hardware Reset

The devices may be reset by driving the RESET pin to VIL from VIH. The RESET pin has a pulse requirement

and has to be kept low (V^IL) 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

“t^READY” after the RESET pin is driven low. Furthermore, once the RESET pin goes high, the devices require an

additional “t^RH” before it will allow read access. When the RESET pin is low, the devices 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.

Write Protect (WP)

The Write Protection function provides a hardware method of protecting certain outermost 8K bytes / 4K words

sectors without using V^ID. This function is one of two provided by the WP/ACC pin.

If the system asserts V^ILon the WP/ACC pin, the device disables program and erase functions in the outermost

8K bytes / 4K words sectors independently of whether this sector was protected or unprotected using the method

described in “Sector Group Protection" above.

If the system asserts V^IHon the WP/ACC pin, the device reverts of whether the outermost 8K bytes / 4K words

sectors were last set to be protected to the unprotected status. Sector protection or unprotection for this sector

depends on whether this was last protected or unprotected using the method described in “Sector protection/

unprotection”.

Accelerated Program Operation

Thedevice offersacceleratedprogramoperationwhichenablesprogramminginhighspeed. Ifthesystemasserts

V^ACCto the WP/ACC pin, the device automatically enters the acceleration mode and the time required for program

operation will reduce to about 85%. This function is primarily intended to allow high speed programing, so caution

is needed as the sector group becomes temporarily 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 V^ACCfrom the WP/ACC pin returns the device to normal operation. Do not remove VACC from the WP/

ACC pin while programming. See “Accelerated Program Timing Diagram” in ■SWITCHING WAVEFORM.

■ COMMAND DEFINITIONS

Device operations are selected by writing specific address and data sequences into the command register.

“MBM29PL32TM/BM Standard Command Definitions” in ■DEVICE BUS OPERATION 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 Reset commands are functionally

equivalent, resetting the device to the read mode. Please note that commands must be asserted to DQ⁷to DQ0

and DQ15 to DQ8 bits are ignored.

Reset Command

In order to return from Autoselect mode or Exceeded Timing Limits (DQ⁵= 1) to Read mode, the Reset operation

is initiated by writing the Reset command sequence into the command register. The devices remain enabled for

reads until the command register contents are altered.

The devices will automatically be in the reset state after power-up. In this case, a command sequence is not

required in order to read data.

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 devices reside in the target system. PROM pro-

grammers typically access the signature codes by raising A⁹to a high voltage. However applying 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 method-

ology. 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 address and the Autoselect command. Then the manufacture and device codes can be

read from the address, and an actual data of memory cell can be read from the another address.

Following the command write, a read cycle from address 00h returns the manufactures’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 address of 0Eh as well as at 0Fh. Notice that above applies to Word mode. The addresses

and codes differ from those of Byte mode. Refer to “Sector Group Protection Verify Autoselect Codes” in ■DE-

VICE BUS OPERATION.

To terminatetheoperation, itisnecessary to write the Reset command into the register. To execute theAutoselect

command during the operation, Reset command must be written before the Autoselect command.

Programming

The devices are programmed on a 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 CEor 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 are automatically performed at the memory location being programmed.

The programming operation is completed when the data on DQ⁷is equivalent to data written to this bit at which

the devices return to the read mode and plogram addresses are no longer latched. Therefore, the devices require

that a valid address to the devices be supplied by the system at this particular instance. Hence Data Polling

requires the same address which is being programmed.

If hardware reset occurs during the programming operation, the data being written is not guaranteed.

28

Retired ProductꢀDS05-20907-4E_July 31, 2007

MBM29PL32TM/BM90/10

Programming is allowed in any address sequence and across sector boundaries. Beware that a data “0” cannot

be programmed back to a “1”. Attempting to do so may result in either failure condition or an apparent success

according to the data polling algorithm. But a read from Reset mode will show that the data is still “0”. Only erase

operations can convert “0”s to “1”s.

Note that attempting to program a “1” over a “0” will result in programming failure. This precaution is the same

with Fujitsu standard NOR devices. “Embedded Program^TMAlgorithm” in ■FLOW CHART illustrates the Em-

bedded Program^TMAlgorithm 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 Embedded Program operation imme-

diately suspends the programming.

When the Program Suspend command is written during a programming process, the device halts the program

operation within 1us 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 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.

When issuing program suspend command in 4 μs after issuing program command, determine the status of

program operation by reading status bit at more 4 μs after issuing program resume command.

The system also writes the Autoselect command sequence 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 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 resumes programming.

Do not read CFI code after HiddenROM Entry and Exit in program suspend mode.

Write Buffer Programming Operations

Write Buffer Programming allows the system write to series of 16 words in one programming operation. This

results in faster effective word programming time than the standard programming algorithms. The Write Buffer

Programming command sequence is initiated by first writing two unlock cycles. This is followed by a third write

cycle selecting the Sector Address in which programming will occur. In forth cycle contains both Sector Address

and unique code for data bus width will be loaded into the page buffer at the Sector Address in which programming

will occur.

The system then writes the starting address/data combination. This “starting address” must be the same Sector

Address used in third and fourth cycles and its lower addresses of A³to A0 should be 0h. All subsequent address

must be incremented by 1. 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 Write Buffer Programming Operations com-

mand 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.

DQ⁷(Data Polling), DQ6(Toggle Bit), DQ5(Exceeded Timing Limits), DQ1(Write-to-Buffer Abort) should be mon-

itored to determine the device status during Write Buffer Programming. In addition to these functions, it is also

possible to indicate to the host system that Write Buffer Programming Operations are either in progress or have

been completed by RY/BY. See “Hardware Sequence Flags”.

The Data polling techniques described in “Data Polling Algorithm” in ■FLOW CHART should be used while

monitoring the last address location loaded into the write buffer. In addition, it is not neccessary to specify an

29

Retired ProductꢀDS05-20907-4E_July 31, 2007

MBM29PL32TM/BM90/10

address in Toggle Bit techniques described in “Toggle Bit Algorithm” in ■FLOW CHART. The automatic pro-

graming operation is completed when the data on DQ7 is equivalent to the data written to this bit at which time

the device returns to the read mode and addresses are no longer latched ( See "Hardware Sequence Flags").

The write-buffer programming operation can be suspended using the standard program suspend/resume com-

mands.

Once the write buffer programming is set, the system must then write the “Program Buffer to Flash” command

at the Sector Address. Any other address/data combination will abort the Write Buffer Programming operation

and the device will continue busy state.

The Write Buffer Programming Sequence can be ABORTED by doing the following :

• Different Sector Address is asserted.

• Write data other than the “Program Buffer to Flash" command after the specified number of “data load” cycles.

A “Write-to-Buffer-Abort Reset” command sequence must be written to the device to return to read mode. (See

“MBM29PL32TM/BM Standard Command Definitions” in ■DEVICE BUS OPERATION for details on this com-

mand sequence.)

Chip Erase

Chip erase is a six bus cycle operation. It begins two “unlock” write cycles followed by writing the “set-up”

command, and two “unlock” write cycles followed by the chip erase command which invokes the Embedded

Erase algorithm.

The device does not require the user to program the device prior to erase. Upon executing the Embedded Erase

Algorithm the devices automatically programs and verifies 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 erase operation status by using DQ⁷(Data Polling), DQ6 (Toggle Bit I) and DQ2

(Toggle Bit II) or RY/BY output signal. The chip erase begins on the rising edge of the last CE or WE, whichever

happens first from last command sequence and completes when the data on DQ⁷is “1” (See Write Operation

Status section.) at which time the device returns to read mode.

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.

Multiple sectors may be erased concurrently by writing the same six bus cycle operations. 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 Erase Time-out time(t^TOW). 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 this condition. The interrupts can reoccur after the last Sector Erase command is written. A time-out

of “t^TOW” 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 DQ³to determine if the sector erase timer window is still open, see section

DQ³, Sector Erase Timer). Resetting the devices 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 the Write Operation Status).

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 devices prior to erase. The devices automatically program

all memory locations in the sector(s) to be erased prior to electrical erase using the Embedded Erase Algorithm.

When erasing a sector, the remaining unselected sectors 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 “t^TOW” time-out from the rising edge of CE or WE whichever happens first for

the last sector erase command pulse and completes when the data on DQ⁷is “1” (see Write Operation Status

section), at which the devices return to the read mode. Data polling and Toggle Bit must be performed at an

address within any of the sectors being erased.

30

Retired ProductꢀDS05-20907-4E_July 31, 2007

MBM29PL32TM/BM90/10

Erase Suspend/Resume

The Erase Suspend command allows the user to interrupt Sector Erase operation and then perform read or

programming to a sector not being erased. This command is applicable ONLY during the Sector Erase operation

within the time-out period for sector erase. 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.

When the "Erase Suspend" command is written during the Sector Erase operation, the device takes maximum

of “t^SPD” to suspend the erase operation. When the devices enter the erase-suspended mode, the RY/BY output

pin will be at High-Z and the DQ⁷bit will be at logic “1” and DQ6 will stop toggling. The user must use the address

of the erasing sector for reading DQ⁶and DQ7 to determine if the erase operation has been suspended. Further

writes of the Erase Suspend command are ignored.

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.

Do not issue program command after entering erase-suspend-read mode.

Fast Mode Set/Reset

The device has Fast Mode function. It dispenses with the initial two unclock cycles required in the standard

program command sequence by writing Fast Mode command into the command register. In this mode, the

required bus cycle for programming consists of two cycles instead of four bus cycles in standard program

command. The read operation is also executed after exiting this mode. During the Fast mode, do not write any

command other than the Fast program/Fast mode reset command. To exit from this mode, write Fast Mode

Reset command into the command register. (Refer to the “Embedded Program^TMAlgorithm for Fast Mode” in

■FLOW CHART.) The V^CCactive current is required even CE = VIH during Fast Mode.

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 “Embedded

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 V^IDon RESET pin and writes a command

sequence. Unlike conventional procedures, it is not necessary to force V^IDand control timing for control pins.

The only RESET pin requires VID for sector group protection in this mode. The extended sector group protection

requires V^IDon RESET pin. With this condition, the operation is initiated by writing the set-up command (60h)

into the command register. Then the sector group addresses pins (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 (set VIL for the other

addresses pins is recommended), 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 (A²⁰, A19, A18, A17, A16, A15, A14, A13 and A12) and (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) should be set and write

a command (40h). Following the command write, a logical “1” at device output DQ⁰will produce for protected

sector in the read operation. If the output data is logical “0”, write the extended sector group protection command

(60h) again. To terminate the operation, set RESET pin to VIH. (Refer to the “Extended Sector Group Protection

Timing Diagram” in ■SWITCHING WAVEFORMS and “Extended Sector Group Protection Algorithm” in■FLOW

CHART.)

Query Command (CFI : Common Flash Memory Interface)

The CFI (Common Flash Memory Interface) specification outlines device and host system software interrogation

handshake which allows specific vendor-specified software algorithms to be used for entire families of devices.

This allows device-independent, JEDEC ID-independent, and forward-and backward-compatible software sup-

port for the specified flash device families. Refer to CFI specification in detail.

The operation is initiated by writing the query command (98h) into the command register. Following the command

write, a read cycle from specific address retrieves device information. Please note that output data of upper byte

(DQ¹⁵to DQ8) is “0”. Refer to the CFI code table. To terminate operation, it is necessary to write the Reset

command sequence into the register. (See “Common Flash Memory Interface Code” in ■DEVICE BUS OPER-

ATION.)

HiddenROM Mode

(1) HiddenROM Region

The HiddenROM (HiddenROM) 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 HiddenROM 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.

The HiddenROM region is 256 bytes / 128 words in length. After the system writes the HiddenROM Entry

command sequence, it may read the HiddenROM region by using device addresses A⁶to A0 (A20 to A7 are all

“0”). That is, the device sends only program command that would normally be sent to the address to the

HiddenROM region. This mode of operation continues until the system issues the Exit HiddenROM 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 address.

If you request Fujitsu to program the ESN in the device, please contact a Fujitsu representative for more

information.

(2) HiddenROM Entry Command

The device has a HiddenROM 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 HiddenROM area is 256 bytes / 128 words. This area is in SA0 . Therefore, write the HiddenROM entry

command sequence to enter the HiddenROM area. It is called HiddenROM mode when the HiddenROM area

appears.

Sectors other than the block area SA0 can be read during HiddenROM mode. Read/program of the HiddenROM

area is possible during HiddenROM mode. Write the HiddenROM reset command sequence to exit the Hidden-

ROM mode. Note that any other commands should not be issued than the HiddenROM program/protection/reset

commands during the HiddenROM mode. When you issue the other commands including the suspend resume

capability, send the HiddenROM reset command first to exit the HiddenROM mode and then issue each com-

mand.

MBM29PL32TM/BM90/10

(3) HiddenROM Program Command

To program the data to the HiddenROM area, write the HiddenROM program command sequence during Hid-

denROM mode. This command is the same as the usual program command, except that it needs to write the

command during HiddenROM mode. Therefore the detection of completion method is the same as in the past,

using the DQ⁷data pooling, DQ6 Toggle bit or RY/BY. You should pay attention to the address to be programmed.

If an address not in the HiddenROM area is selected, the previous data will be deleted.

During the write into the HiddenROM region, the program suspend command issuance is prohibited.

(4) HiddenROM Protect Command

There are two methods to protect the HiddenROM area. One is to write the sector group protect setup command

(60h) , set the sector address in the HiddenROM area and (A⁶, A3, A2, A1, A0) = (0, 0, 0, 1, 0) , and write the

sector group protect command (60h) during the HiddenROM 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 HiddenROM

mode and does not apply high voltage to the RESET pin. Please refer to above mentioned “Extended Sector

Group Protection” for details of sector group protect setting.

The other method is to apply high voltage (V^ID) to A9 and OE, set the sector address in the HiddenROM area

and (A⁶, A3, A2, A1, A0) = (0, 0, 0, 1, 0) , and apply the write pulse during the HiddenROM mode. To verify the

protect circuit, apply high voltage (V^ID) to A9, specify (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) and the sector address

in the HiddenROM area, and read. When “1” appears on DQ⁰, the protect setting is completed. “0” will appear

on DQ⁰if it is not protected. Apply write pulse again. The same command sequence could be used for the above

method because other than the HiddenROM mode, it is the same as the sector group protect previously men-

tioned.

Take note that other sector groups will be affected if an address other than those for the HiddenROM area is

selected for the sector group address, soplease be careful. Pay close attentionthat once it is protected, protection

CANNOT BE CANCELLED.

Write Operation Status

Detailed in “Hardware Sequence Flags” are all the status flags which can determine the status of the device for

current mode operation. When checking Hardware Sequence Flags during program operations, it should be

checked 4 μs after issuing program command. During sector erase, the part provides the status flags automat-

ically to the I/O ports. The information on DQ²is address sensitive. If an address from an erasing sector is

consecutively read, then the DQ²bit will toggle. However DQ2 will not toggle if an address from a non-erasing

sector is consecutively read. This allows the user to determine which sectors are erasing.

Once erase suspend is entered address sensitivity still applies. If the address of a non-erasing sector (one

available for read) is provided, then stored data can be read from the device. If the address of an erasing sector

(one unavailable for read) is applied, the device will output its status bits.

DQ⁷

Data Polling

The devices feature Data Polling as a method to indicate to the host that the Embedded Algorithms are in

progress or completed. During the Embedded Program Algorithm, an attempt to read devices will produce

reverse 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 DQ⁷output. Upon completion of the Embedded Erase Algorithm, an attempt to

read device will produce a “1” at the DQ⁷output. The flowchart for Data Polling (DQ7) is shown in “Data Polling

Algorithm” in ■FLOW CHART.

For programming, the Data Polling is valid after the rising edge of fourth write pulse in the four write pulse

sequence.

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

write pulse sequence. DataPolling 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

the device returns to 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 100 μs, then the device returns to read mode. If

not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and

ignores the selected sectors that are protected.

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 the device is driving status

information on DQ⁷at one instant of time, and then that byte’s valid data the next. Depending on when the system

samples the DQ⁷output, it may read the status or valid data. Even if the device completes the Embedded

Algorithm operation and DQ⁷has a valid data, the data outputs on DQ6 to DQ0 may still be invalid. The valid data

on DQ⁷to DQ0 will be read on the successive read attempts.

The Data Polling feature is active only during the Embedded Programming Algorithm, Embedded Erase Algo-

rithm, Erace Suspendmode or sector erase time-out.

See “Data Polling during Embedded Algorithm Operation Timing Diagram” in ■SWITCHING WAVEFORM for

the Data Polling timing specifications and diagram.

DQ⁶

Toggle Bit I

The device also feature the “Toggle Bit I” as a method to indicate to the host system that the Embedded Algorithms

are in progress or completed.

During an Embedded Program or Erase Algorithm cycle, successive attempts to read (CE or OE toggling) data

from the devices will result in DQ⁶toggling between one and zero. Once the Embedded Program or Erase

Algorithm cycle is completed, DQ⁶will 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 programm operation, if the sector being written to is protected, the Toggle bit will toggle for about 1 μs and

then stop toggling with the data unchanged. In erase, the device will erase all the selected sectors except for

the protected ones. If all selected sectors are protected, the chip will toggle the Toggle bit for about 100 μs and

then drop back into read mode, having data kept remained.

Either CE or OE toggling will cause the DQ6 to toggle. See “ Toggle Bit l Timing Diagramduring Embedded

Algorithm Operations” in ■SWITCHING WAVEFORM for the Toggle Bit I timing specifications and diagram.

MBM29PL32TM/BM90/10

DQ⁵

Exceeded Timing Limits

DQ⁵will indicate if the program or erase time has exceeded the specified limits (internal pulse count). Under

these conditions DQ⁵will produce a “1”. This is a failure condition indicating that the program or erase cycle was

not successfully completed. Data Polling is the only operating function of the device under this condition. The

CE circuit will partially power down the device under these conditions (to approximately 2 mA). The OE and WE

pins will control the output disable functions as described in “MBM29PL32TM/BM User Bus Operations (Word

Mode : BYTE = VIH)” and “MBM29PL32TM/BM User Bus Operations (Byte Mode : BYTE = VIL)” in ■DEVICE

BUS OPERATION.

The DQ⁵failure 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 a valid data on DQ⁷bit and DQ6 never stop toggling. Once the device has exceeded timing limits, the DQ5

bit will indicate a “1”. Note that this is not a device failure condition since the device was incorrectly used. If this

occurs, reset the device with command sequence.

DQ³

Sector Erase Timer

After the completion of the initial sector erase command sequence the sector erase time-out will begin. DQ³will

remain low until the time-out is complete. Data Polling and Toggle Bit are valid after the initial sector erase

command sequence.

If Data Polling or the Toggle Bit I indicates a valid erase command has been written, DQ3 may be used to

determine whether the sector erase timer window is still open. If DQ³is “1” the internally controlled erase cycle

has begun. If DQ³is “0”, the device will accept additional sector erase commands. To insure the command has

been accepted, the system software should check the status of DQ³prior to and following each subsequent

SectorErasecommand. IfDQ³were highonthe second statuscheck, thecommandmaynothave been accepted.

See “Hardware Sequence Flags”.

DQ²

Toggle Bit II

This Toggle bit II, along with DQ⁶, can be used to determine whether the devices are in the Embedded Erase

Algorithm or in Erase Suspend.

Successive reads from the erasing sector will cause DQ²to toggle during the Embedded Erase Algorithm. If the

devices are in the erase-suspended-read mode, successive reads from the erase-suspended sector will cause

DQ²to 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 DQ²bit.

DQ⁶is 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, DQ²and DQ6 can be used together to determine if the erase-suspend-read mode is in progress.

(DQ²toggles while DQ6 does not.) See also “Hardware Sequence Flags” and “DQ2 vs. DQ6” in ■SWITCHING

WAVEFORM.

Furthermore, DQ²can 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.

MBM29PL32TM/BM90/10

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 DQ⁷to 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 DQ⁵is 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 DQ⁵has not

gone high. The system may continue to monitor the Toggle bit and DQ⁵through successive read cycles, deter-

mining 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 “Toggle Bit Algorithm” in ■FLOW CHART.)

Write-to-Buffer Abort

DQ1 indicates whether a Write-to-Buffer operation was aborted. Under these conditions DQ1 produces a "1".

The system must issue the Write-to-Buffer-Abort-Reset command sequence to return the device to reading array

data. See "Write Buffer Programming Operations" section for more details.

RY/BY

Ready/Busy

The device provides a RY/BY open-drain output pin to indicate to the host system that the Embedded Algorithms

are either in progress or has been completed. If the output is low, the device is busy with either a program or

erase operation. If the output is high, the device is ready to accept any read/write or erase operation. If the

device is placed in an Erase Suspend mode, the RY/BY output will be high, by means of connecting with a pull-

up resister to V^CC.

During programming, the RY/BY pin is driven low after the rising edge of the fourth WE pulse. During an erase

operation, the RY/BY pin is driven low after the rising edge of the sixth WE pulse. The RY/BY pin will indicate a

busy condition during the RESET pulse. See “RY/BY Timing Diagram during Program/Erase Operation Timing

Diagram” and “RESET Timing Diagram ( During Embedded Algorithms )” in ■SWITCHING WAVEFORM 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.

Word/Byte Configuration

BYTE pin selects the byte (8-bit) mode or word (16-bit) mode for the device. When this pin is driven high, the

device operates in the word (16-bit) mode. Data is read and programmed at DQ¹⁵to DQ0. When this pin is driven

low, the device operates in byte (8-bit) mode. In this mode, DQ¹⁵/A-1 pin becomes the lowest address bit, and

DQ¹⁴to DQ8 bits are tri-stated. However, the command bus cycle is always an 8-bit operation and hence

commands are written at DQ⁷to DQ0 and DQ15 to DQ8 bits are ignored.

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 reset 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 form V^CCpower-up

and power-down transitions or system noise.

(1) Low V^CCWrite Inhibit

To avoid initiation of a write cycle during V^CCpower-up and power-down, a write cycle is locked out for VCC less

than V^LKO. 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 V^CClevel

is greater than V^LKO. It is the user’s responsibility to ensure that the control pins are logically correct to prevent

unintentional writes when V^CCis above VLKO.

If Embedded Erase Algorithm is interrupted, the intervened erasing sector(s) is(are) not valid.

(2) Write Pulse “Glitch” Protection

Noise pulses of less than 3 ns (typical) on OE, CE, or WE will not initiate a write cycle.

(3) Logical Inhibit

Writing is inhibited by holding any one of OE = VIL, CE = VIH, or WE = VIH. To initiate a write, CE and WE must

be a logical zero while OE is a logical one.

(4) Power-up Write Inhibit

Power-up of the devices with WE = CE = VIL and OE = VIH will not accept commands on the rising edge of WE.

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

(5) Sector Protection

Device user is able to protect each sector group individually to store and protect data. Protection circuit voids

both write and erase commands that are addressed to protected sectors.

Any commands to write or erase addressed to protected sector are ignored .
