GENERAL PRODUCT DESCRIPTION

Extra Security Sector of 256 bytes

The ES29LV320 is a 32 megabit, 3.0 volt-only flash

memory device, organized as 4M x 8 bits (Byte

mode) or 2M x 16 bits (Word mode) which is config-

urable by BYTE#. Eight boot sectors and sixty three

main sectors with uniform size are provided :

8Kbytes x 8 and 64Kbytes x 63. The device is man-

ufactured with ESI’s proprietary, high performance

and highly reliable 0.18um CMOS flash technology.

The device can be programmed or erased in-sys-

tem with standard 3.0 Volt Vcc supply ( 2.7V-3.6V)

and can also be programmed in standard EPROM

programmers. The device offers minimum endur-

ance of 100,000 program/erase cycles and more

than 10 years of data retention.

In the device, an extra security sector of 256 bytes is

provided to customers. This extra sector can be

used for various purposes such as storing ESN

(Electronic Serial Number) or customer’s security

codes. Once after the extra sector is written, it can

be permanently locked by the device manufacturer(

factory-locked) or a customer( customer-lock-

able). At the same time, a lock indicator bit (DQ7)

is permanently set to a 1 if the part is factory- locked,

or set to 0 if it is customer-lockable. Therefore, this

lock indicator bit (DQ7) can be properly used to

avoid that any customer-lockable part is used to

replace a factory-locked part. The extra security

sector is an extra memory space for customers

when it is used as a customer-lockable version. So,

it can be read and written like any other sectors. But

it should be noted that the number of E/W(Erase and

Write) cycles is limited to 300 times (maximum) only

in the Security Sector.

The ES29LV320 offers access time as fast as 80ns

or 90ns, allowing operation of high-speed micropro-

cessors without wait states. Three separate control

pins are provided to eliminate bus contention : chip

enable (CE#), write enable (WE#) and output

enable (OE#).

Special services such as ESN and factory-lock are

available to customers ( ESI’s Special-Code ser-

vice ) The ES29LV320 is completely compatible with

the JEDEC standard command set of single power

supply Flash. Commands are written to the internal

command register using standard write timings of

microprocessor and data can be read out from the

cell array in the device with the same way as used in

other EPROM or flash devices.

All program and erase operation are automatically

and internally performed and controlled by embed-

ded program/erase algorithms built in the device.

The device automatically generates and times the

necessary high-voltage pulses to be applied to the

cells, performs the verification, and counts the num-

ber of sequences. Some status bits (DQ7, DQ6 and

DQ5) read by data# polling or toggling between

consecutive read cycles provide to the users the

internal status of program/erase operation: whether

it is successfully done or still being progressed.

DEVICE BUS OPERATIONS

on the device address inputs produce valid data on

the device data outputs. The device stays at the read

mode until another operation is activated by writing

commands into the internal command register. Refer

to the AC read cycle timing diagrams for further

details ( Fig. 18 ).

Several device operational modes are provided in

the ES29LV320 device. Commands are used to ini-

tiate the device operations. They are latched and

stored into internal registers with the address and

data information needed to execute the device

operation.

The available device operational modes are listed

in Table 1 with the required inputs, controls, and the

resulting outputs. Each operational mode is

described in further detail in the following subsec-

tions.

Word/Byte Mode Configuration ( BYTE# )

The device data output can be configured by BYTE#

into one of two modes : word and byte modes. If the

BYTE# pin is set at logic ‘1’, the device is configured

in word mode, DQ0 - DQ15 are active and controlled

by CE# and OE#. If the BYTE# pin is set at logic ‘0’,

the device is configured in byte mode, and only data

I/O pins DQ0 - DQ7 are active and controlled by CE#

and OE#. The data I/O pins DQ8 - DQ14 are tri-

stated, and the DQ15 pin is used as an input for the

LSB (A-1) address.

Read

The internal state of the device is set for the read

mode and the device is ready for reading array data

upon device power-up, or after a hardware reset. To

read the stored data from the cell array of the

device, CE# and OE# pins should be driven to V

control and gates array data to the output pins.

When the device is not selected or activated in a

system, it needs to stay at the standby mode, in

which current consumption is greatly reduced with

outputs in the high impedance state.

Word or byte mode of output data is determined by

the BYTE# pin. No additional command is needed

in this mode to obtain array data. Standard micro-

processor read cycles that assert valid addresses

The entire memory space of cell array is divided

into a many of small sectors: 8kbytes x 8 boot sec-

tors and 64Kbytes x 63 main sectors. In erase

access, before it is ready for read data. And even if

the device is deselected by CE# pin during erase or

programming operation, the device draws active cur-

rent until the operation is completely done. While the

device stays in the standby mode, the output is

placed in the high impedance state, independent of

the OE# input.

Accelerated Program Mode

The device offers accelerated program operations

through the ACC function. This is one of two func-

tions provided by the WP#/ACC pin. This function

is primarily intended to allow faster manufacturing

signals.

Autoselect Mode

Writing Commands

Flash memories are intended for use in applica-

tions where the local CPU alters memory contents.

In such applications, manufacturer and device

identification (ID) codes must be accessible while

the device resides in the target system ( the so

called “in-system program”). On the other hand,

signature codes have been typically accessed by

raising A9 pin to a high voltage in PROM program-

mers. However, multiplexing high voltage onto

address lines is not the generally desired system

design practice. Therefore, in the ES29LV320

device an autoselect command is provided to

allow the system to access the signature codes

without any high voltage. The conventional A9

high-voltage method used in the PROM program-

ers for signature codes are still supported in this

device.

To write a command or command sequences to ini-

tiate some operations such as program or erase, the

system must drive WE# and CE# to V , and OE# to

IL

V . For program operations, the BYTE# pin deter-

IH

mines whether the device accepts program data in

bytes or words. Refer to “BYTE# timings for Write

Operations” in the Fig. 21 for more information.

Unlock Bypass Mode

To reduce more the programming time, an unlock-

bypass mode is provided. Once the device enters

this mode, only two write cycles are required to ini-

tiate the programming operation instead of four

cycles in the normal program command sequences

which are composed of two unlock cycles, program

If the system writes the autoselect command

sequence, the device enters the Autoselect mode.

The system can then read some useful codes such

as manufacturer and device ID from the internal reg-

isters on DQ7 - DQ0. Standard read cycle timings

apply in this mode. In the Autoselect mode, the fol-

lowing four informations can be accessed through

either autoselect command method or A9 high-volt-

age autoselect method. Refer to the Table 2.

boot-up firmware from the Flash memory.Refer to

the AC Characteristics tables for RESET# parame-

SECTOR GROUP PROTECTION

The ES29LV320 features hardware sector group

protection. A sector group consists of two or more

adjacent sectors that are protected or unprotected

at the same time. In the device, sector protection is

performed on the group of sectors previously

defined in the Table 3-4. Once after a group of sec-

tors are protected, any program or erase operation

is not allowed in the protected sector group. The

previously protected sectors must be unprotected

by one of the unprotect methods provided here

before changing data in those sectors. Sector pro-

tection can be implemented via two methods.

Hardware Device Reset ( RESET# )

The RESET# pin provides a hardware method of

resetting the device to read array data. When the

RESET# pin is driven low for at least a period of t

the device immediately terminates any operation in

progress, tristates all output pins, and ignores all

read/write commands for the duration of the

state machine to reading array data. The operation

that was interrupted should be reinitiated once after

the device is ready to accept another command

sequence, to ensure data integrity.

In-system protection

A9 High-voltage protection

To check whether the sector group protection was

successfully executed or not, another operation

called “protect verification” needs to be per-

formed after the protection operation on a group of

sectors. All protection and protect verifications pro-

vided in the device are summarized in detail at the

write cycle to avoid any over-erase due to the intrin-

sic erase characteristics of the protection cell. After

the unprotection operation, all previously protected

sectors will need to be individually re-protected.

Standard microprocessor bus cycle timings are used

in the unprotection and unprotect verification opera-

tions. Three unprotect methods are provided in the

ES29LV320 device. All unprotection and unprotect

verification cycles are summarized in detail at the

Table 1.

IL

device disables program and erase functions in the

two “outermost” 8Kbytes boot sectors indepen-

dently of whether those sectors were protected or

unprotected using the method described in “Sector

Group Protection and Unprotection”. The two outer-

most of 8 Kbyte 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-configured device.

service

SECURITY SECTOR

The security sector of the ES29LV320 device pro-

vides an extra flash memory space that enables

permanent part identification through an Electronic

Serial Number (ESN). The security sector uses a

security lock-Indicator Bit (DQ7) to indicate

whether or not the security sector is locked when

shipped from the factory. This bit is permanently set

at the factory and cannot be changed, which pre-

vents cloning of a factory locked part. This ensures

the security of the ESN once the product is shipped

to the field. Note that the ES29LV320 has a security

sector size of 256 bytes.

- Both a random, secure ESN and customer

code through the ESI’s Special-Code service.

ESN ( Electronic Serial Number )

In devices that have an ESN, a Bottom Boot device

will have the 16-byte (8-word) ESN in sector 0 at

addresses 000000h-00000Fh in byte mode (or

000000h-000007h in word mode). In the Top Boot

device the ESN will be in sector 70 at addresses

3FFF00h-3FFF0Fh in byte mode (or 1FFF80h-

1FFF87h in word mode). Note that in upcoming top

boot versions of this device, the ESN will be located

in sector 70 at addresses 3FFF00h-3FFF0Fh in byte

mode (or 1FFF80h-1FFF87h in word mode).

Security Lock-Indicator Bit (DQ7)

In the device, the security sector can be provided in

either factory locked version or customer lockable

version. The factory-locked version is always pro-

tected when shipped from the factory, and has the

security lock-Indicator Bit permanently set to a “1”.

The customer-lockable version is shipped with

the security sector unprotected, allowing customers

to utilize the sector in any manner they choose. The

customer-lockable version has the security lock-

Indicator Bit permanently set to a “0”. Thus, the

security lock-Indicator Bit prevents customer-lock-

able devices from being used to replace devices

that are factory locked.

ESI’s Special-Code Service

Customers may opt to have their code programmed

by ESI through the ESI’s Special-Code service. ESI

programs the customer’s code, with or without the

random ESN. The devices are then shipped from

ESI’s factory with the Security Sector permanently

locked. Contact an ESI representative for details on

using ESI’s Special-Code service.

Customer-Lockable Device

The customer lockable version allows the security

sector to be freely programmed or erased and then

permanently locked. Note that the ES29LV320 has

a security sector size of 256 bytes (128 words). Note

that the accelerated programming (ACC) and unlock

bypass functions are not available when program-

ming the security sector.

Access to the Security Sector

The security sector can be accessed through a

command sequence: Enter security and Exit

security sector commands. After the system has

written the Enter security sector command

sequence, it may read the security sector by using

the addresses normally occupied by the boot sec-

tors. This mode of operation continues until the sys-

tem issues the Exit security sector command

sequence, or until power is removed from the

device. On power-up, or following a hardware reset,

the device returns to read mode in which the nor-

mal boot sectors can be accessed, instead of the

security sector.

Protection of the Security Sector

The security sector area can be protected using the

following procedures: Write the three-cycle “Enter

security sector command” sequence, and then fol-

lowing the in-system sector protect algorithm as

shown in Fig. 2, except that RESET# may be at

either V or V . This allows in-system protection

ID

of the security sector without raising any device pin

to a high voltage. Note that this method is only appli-

cable to the security sector. To verify the protect/

unprotect status of the security sector. follow the

algorithm shown in Fig. 2.

Factory-Locked Device

In a factory-locked device, the security sector is

protected when the device is shipped from the fac-

tory. The security sector cannot be modified in any

way. The device is available preprogrammed with

one of the following:

cycle, CE# and WE# must be a logical zero while

OE# is a logical one.

Power-up Write Inhibit

Once the Security Sector is locked protected and

verified, the system must write the Exit Security

Sector Region command sequence to return to

reading and writing the remainder of the array.

If WE#=CE#=V and OE#=V during power up, the

IL

IH

device does not accept any commands on the rising

edge of WE#. The internal state machine is automat-

ically reset to the read mode on power-up.

Caution for the Security Sector Protection

The security sector protection must be used with

caution since, once protected, there is no proce-

dure available for unprotecting the security sector

area and none of the bits in the security sector

memory space can be modified in any way.

HARDWARE DATA PROTECTION

The ES29LV320 device provides some protection

measures against accidental erasure or program-

ming caused by spurious system level signals that

may exist during power transition. During power-

up, all internal registers and latches in the device

are cleared and the device automatically resets to

the read mode. In addition, with its internal state

machine built-in the device, any alteration of the

memory contents or any initiation of new operation

This device enters the CFI Query mode when the

system writes the CFI query command, 98h, to

address 55h in word mode (or address AAh in byte

mode), any time the device is ready to read array

data. The system can read CFI information at the

addresses given in Tables 5-8. To terminate reading

CFI data, the system must write the reset com-

mand.The CFI query command can be written to the

system when the device is in the autoselect mode

or the erase-suspend-read mode. The device

enters the CFI query mode, and the system can read

CFI data at the addresses given in Tables 5-8.

When the reset command is written, the device

returns respectively to the read mode or erase-sus-

pend-read mode.

Common Flash Memory

Interface (CFI)

CFI is supported in the ES29LV320 device. The

Common Flash Interface (CFI) specification out-

lines device and host system software interrogation

handshake, which allows specific vendor-specified

software algorithms to be used for entire families of

devices. Software support can then be device-inde-

pendent, JEDEC ID-independent, and forward- and

backward-compatible for the specified flash device

families. Flash vendors can standardize their exist-

ing interfaces for long-term compatibility.

COMMAND DEFINITIONS

Writing specific address and data commands or

sequences into the command register initiates

device operations. Table 9 defines the valid register

command sequences. Note that writing incorrect

address and data values or writing them in the

improper sequence may place the device in an

unknown state. A reset command is required to

return the device to normal operation.

the Device Bus Operations section for more informa-

tion.The Read-Only Operations table provides the

read parameters, and Fig. 18 shows the timing dia-

gram

RESET COMMAND

Writing the reset command resets the device to the

read or erase-suspend-read mode. Address bits are

don’t cares for this command.

All addresses are latched on the falling edge of WE#

or CE#, whichever happens later. All data is latched

on the rising edge of WE# or CE#, whichever hap-

pens first. Refer to the AC Characteristics section for

timing diagrams.

The reset command may be written between the

sequence cycles in an erase command sequence

before erasing begins. This resets the device to

which the system was writing to the read mode.

Once erasure begins, however, the device ignores

reset commands until the operation is complete.

READING ARRAY DATA

The device is automatically set to reading array data

after device power-up. No commands are required

to retrieve data. The device is ready to read array

data after completing an Embedded Program or

Embedded Erase algorithm.

The reset command may be written between the

sequence cycles in a program command sequence

before programming begins. This resets the device

to which the system was writing to the read mode. If

the program command sequence is written to a sec-

tor that is in the Erase Suspend mode, writing the

reset command returns the device to the erase-sus-

pend-read mode. Once programming begins, how-

ever, the device ignores reset commands until the

operation is complete.

After the device accepts an Erase Suspend com-

mand, the device enters the erase-suspend-read

mode, after which the system can read data from

any non-erase-suspended sector. After completing a

programming operation in the Erase Suspend mode,

the system may once again read array data with the

same exception. See the Erase Suspend/Erase

Resume Commands section for more information.

The reset command may be written between the

sequence cycles in an autoselect command

sequence. Once in the autoselect mode, the reset

command must be written to return to the read

mode. If the device entered the autoselect mode

while in the Erase Suspend mode, writing the reset

command returns the device to the erase-suspend-

read mode.

The system must issue the reset command to return

the device to the read (or erase-suspend-read)

mode if DQ5 goes high during an active program or

erase operation, or if the device is in the autoselect

mode. See the next section, Reset Command, for

more information.

If DQ5 goes high during a program or erase opera-

tion, writing the reset command returns the device to

the read mode (or erase-suspend-read mode if the

device was in Erase-Suspend).

AUTOSELECT COMMAND

SECURITY SECTOR COMMAND

In the ES29LV320 device, the security sector region

(256 bytes) provides a secured data area containing

a random, sixteen-byte electronic serial num-

ber(ESN) or customer’s security codes. The secu-

rity sector region can be accessed by issuing the

three-cycle Enter Security Sector command

sequence. The device continues to access the

security sector region until the system issues the

four-cycle Exit Security Sector command

sequence. The Exit Security Sector command

sequence returns the device to normal operation.

Table 9 shows the address and data requirements

for both command sequences. Note that the accel-

erated programming function by WP#ACC and

unlock bypass mode are not available when the

device has entered the security sector. Refer to the

Fig. 7 for the security sector operation.

The autoselect command sequence allows the host

system to access the manufacturer and device

codes, and determine whether or not a sector is

protected, including information about factory-

locked or customer lockable version.

Table 9 shows the address and data requirements.

This method is an alternative to “A9 high-voltage

PROM programmers and requires V on address

pin A9. The autoselect command sequence may be

written to an address within sector that is either in

the read mode or erase-suspend-read mode. The

auto-select command may not be written while the

device is actively programming or erasing. The

autoselect command sequence is initiated by first

writing two unlock cycles. This is followed by a third

write cycle that contains the autoselect command.

The device then enters the autoselect mode. The

system may read at any address any number of

times without initiating another autoselect com-

mand sequence.

Once after the device enters the auto-select mode,

the manufacture ID code ( 4Ah ) can be accessed

by one of two ways. Just one read cycle ( with A6,

A1 and A0 = 0 ) can be used. Or four consecutive

read cycles ( with A6 = 1 and A1, A0 = 0 ) for con-

tinuation codes (7Fh) and then another last cycle

for the code (4Ah) (with A6, A1 and A0 = 0) can be

used for reading the manufacturer code.

BYTE / WORD PROGRAM

Program Status Bits : DQ7, DQ6 or RY/BY#

The system may program the device by word or

byte, depending on the state of the BYTE# pin.

Programming is a four-bus-cycle operation. The

program command sequence is initiated by writing

two unlock write cycles, followed by the program

set-up command. The program address and data

are written next, which in turn initiate the Embedded

Program algorithm. The system is not required to

provide further controls or timings. The device auto-

matically provides internally generated program

pulses and verifies the programmed cell margin.

Table 9 shows the address and data requirements

for the byte program command sequence. Note that

the autoselect, commands related with the security

sector, and CFI modes are unavailable while a pro-

gramming operation is in progress.

When the Embedded Program algorithm is com-

plete, the device then returns to the read mode and

addresses are no longer latched. The system can

determine the status of the program operation by

using DQ7, DQ6, or RY/BY#. Refer to the Write

Operation Status section Table 10 for information on

these status bits.

Any Commands Ignored during Program-

ming Operation

Any commands written to the device during the

Embedded Program algorithm are ignored. Note that

a hardware reset can immediately terminates the

program operation. The program command

sequence should be reinitiated once the device has

returned to the read mode, to ensure data integrity.

Programming from “0” back to “1”

Programming is allowed in any sequence and

across sector boundaries. But a bit cannot be pro-

grammed from “0” back to a ”1”. Attempting to do so

may cause the device to set DQ5 = 1, or cause the

DQ7 and DQ6 status bits to indicate the operation

was successful. However, a succeeding read will

show that the data is still “0”. Only erase operations

can convert a “0” to a “1”

In the ES29LV320 device, an unlock bypass pro-

gram mode is provided for faster programming oper-

ation. In this mode, two cycles of program command

sequences can be saved. To enter this mode, an

unlock bypass enter command should be first written

to the system. The unlock bypass enter command

sequence is initiated by first writing two unlock

cycles. This is followed by a third write cycle contain-

ing the unlock bypass command, 20h. The device

then enters the unlock-bypass program mode. A

two-cycle unlock bypass program command

sequence is all that is required to program in this

mode. The first cycle in this sequence contains the

unlock bypass program set-up command, A0h; the

second cycle contains the program address and

data. Additional data is programmed in the same

manner. This mode dispenses with the initial two

unlock cycles required in the standard program com-

mand sequence, resulting in faster total program-

may result. Fig. 8 illustrates the algorithm for the

for parameters, and Fig. 22 for timing diagrams.

SECTOR ERASE COMMAND

By using a sector erase command, a single sector or

multiple sectors can be erased. The sector erase

command is a six bus cycle operation. The sector

erase command sequence is initiated by writing two

unlock cycles, followed by a set-up command. Two

additional unlock cycles are written, and are then fol-

lowed by the address of the sector to be erased, and

the sector erase command. Table 9 shows the

address and data requirements for the sector erase

command sequence. Note that the autoselect, secu-

rity sector, and CFI modes are unavailable while an

erase operation is in progress.

CHIP ERASE COMMAND

To erase the entire memory, a chip erase command

is used. This command is a six bus cycle operation.

The chip erase command sequence is initiated by

writing two unlock cycles, followed by a set-up com-

mand. Two additional unlock write cycles are then

followed by the chip erase command, which in turn

invokes the Embedded Erase algorithm. The chip

erase command erases the entire memory includ-

ing all other sectors except the protected sectors,

but the internal erase operation is performed on a

single sector base.

Embedded Sector Erase Algorithm

The device does not require the system to prepro-

gram prior to erase. The Embedded Erase algorithm

automatically programs and verifies the entire mem-

ory for an all zero data pattern prior to electrical

erase. The system is not required to provide any con-

trols or timings these operations.

Sector Erase Time-out Window and DQ3

Status Bits : DQ7,DQ6,DQ2, or RY/BY#

After the command sequence is written, a sector

erase time-out of 50us occurs. During the time-out

period, additional sector addresses and sector

erase commands may be written. Loading the sec-

tor erase buffer may be done in any sequence, and

the number of sectors may be from one sector to all

sectors. The time between these additional cycles

must be less than 50 us, otherwise the last address

and command may not be accepted, and erasure

may begin. It is recommended that processor inter-

rupts be disabled during this time to ensure all com-

mands are accepted. The interrupts can be re-

enabled after the last Sector Erase command is

written. The system can monitor DQ3 to determine

if the sector erase timer has timed out (See the sec-

tion on DQ3:Sector Erase Timer.). The time-out

begins from the rising edge of the final WE# pulse

in the command sequence.

When the Sector Erase Embedded Erase algorithm

is complete, the device returns to reading array data

and addresses are no longer latched. Note that while

the Embedded Erase operation is in progress, the

system can read data from the non-erasing sector.

The system can determine the status of the erase

operation by reading DQ7,DQ6,DQ2, or RY/BY# in

the erasing sector. Refer to the Write Operation Sta-

tus section Table 10 for information on these status

bits.

Valid Command during Sector Erase

Once the sector erase operation has begun, only the

Erase Suspend command is valid. All other com-

mands are ignored. However, note that a hardware

reset immediately terminates the erase operation. If

that occurs, the sector erase command sequence

should be reinitiated once the device has returned to

reading array data, to ensure data integrity.

Any command other than Sector Erase or Erase

Suspend during the time-out period resets the

device to the read mode. The system must rewrite

the command sequence and any additional

addresses and commands.

Fig. 9 illustrates the algorithm for the erase opera-

tion. Refer to the Erase and Program Operations

tables in the AC Characteristics section for parame-

ters, and Fig. 23 section for timing diagrams.

ERASE SUSPEND/ERASE RESUME

An erase operation is a long-time operation so that

two useful commands are provided in the

ES29LV320 device Erase Suspend and Erase

Resume Commands. Through the two commands,

erase operation can be suspended for a while and

the suspended operation can be resumed later when

it is required. While the erase is suspended, read or

program operations can be performed by the system.

Erase Suspend Command, (B0h)

The Erase Suspend command, B0h, allows the sys-

read data from, or program data to, any sector not

selected for erasure. This command is valid only dur-

ing the sector erase operation, including the 50us

time-out period during the sector erase command

sequence. The Erase Suspend command is ignored

if written during the chip erase operation or Embed-

ded Program algorithm. When the Erase Suspend

command is written during the sector erase opera-

tion, the device requires a maximum of 20us to sus-

pend the erase operation. However, when the Erase

time-out, the device immediately terminates the time-

Read and Program during Erase-Suspend-

Read Mode

After the erase operation has been suspended, the

device enters the erase-suspend-read mode. The

system can read data from or program data to any

sector not selected for erasure. (The device “erase

suspends” all sectors selected for erasure.) Reading

at any address within erase-suspended sectors pro-

duces status information on DQ7-DQ0. The system

can use DQ7, or DQ6 and DQ2 together, to deter-

mine if a sector is actively erasing or is erase-sus-

pended. Refer to the Write Operation Status section

for information on these status bits (Table 10).

After an erase-suspended program operation is

complete, the device returns to the erase-suspend-

read mode. The system can determine the status for

the program operation using the DQ7 or DQ6 status

bits, just as in the standard Byte Program operation.

Refer to the Write Operation Status section for more

information.

Autoselect during Erase-Suspend- Read

Mode

In the erase-suspend-read mode, the system can

also issue the autoselected command sequence.

Refer to the Autoselect Mode and Autoselect Com-

mand Sequence section for details (Table 9).

Erase Resume Command

To resume the sector erase operation, the system

must write the Erase Resume command. Further

writes of the Resume command are ignored.

Another Erase Suspend command can be written

after the chip has resumed erasing.

WRITE OPERATION STATUS

Erase algorithm is complete, or if the device enters

the Erase Suspend mode, Data# polling produces a

“1” on DQ7. The system must provide an address

within any of the sectors selected for erasure to read

valid status information on DQ7.

In the ES29LV320 device, several bits are provided

to determine the status of a program or erase oper-

ation: DQ2, DQ3, DQ5, DQ6, DQ7 and RY/BY#.

Table 10 and the following subsections describe the

function of these bits. DQ7 and DQ6 each offer a

method for determining whether a program or erase

operation is complete or in progress. The device

also provides a hardware-based output signal, RY/

BY#, to determine whether an Embedded Program

or Erase operation is in progress or has been com-

pleted.

Erase on the Protected Sectors

After an erase command sequence is written, if all

sectors selected for erasing are protected, Data#

Polling on DQ7 is active for approximately 1.8us,

then the device returns to the 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. How-

ever, if the system reads DQ7 at an address within a

protected sector, the status may not be valid.

DQ7 (DATA# POLLING)

The Data# Polling bit, DQ7, indicates to the host

system whether an Embedded Program or Erase

algorithm is in progress or completed, or whether a

device is in Erase Suspend. Data# Polling is valid

after the rising edge of the final WE# pulse in the

command sequence.

Data# Polling Algorithm

Just prior to the completion of an Embedded

Program or Ease operation, DQ7 may change

asynchronously with DQ0-DQ6 while Output

Enable(OE#) is asserted low. That is, this device

may change from providing status information to

valid data on DQ7. Depending on when the system

samples the DQ7 output, it may read the status or

valid data. Even if the device has completed the

program or erase operation and DQ7 has valid data,

the data outputs on DQ0-DQ7 will appear on

successive read cycles.

During Programming

During the Embedded Program algorithm, the

device outputs on DQ7 the complement of the

datum programmed to DQ7. This DQ7 status also

applies to programming during Erase Suspend.

When the Embedded Program algorithm is com-

plete, the device outputs the datum programmed to

DQ7. The system must provide the program

address to read valid status information on DQ7. If

a program address falls within a protected sector,

Data# Polling on DQ7 is active for approximately

250ns, then the device returns to the read mode.

Table 10 shows the outputs for Data# Polling on

DQ7. Fig. 11 shows the Data# Polling algorithm. Fig.

24 in the AC Characteristics section shows the

Data# Polling timing diagram.

During Erase

During the Embedded Erase algorithm, Data# Poll-

ing produces a “0” on DQ7. When the Embedded

Erase Suspend mode. Toggle Bit I may be read at

any address, and is valid after the rising edge of the

final WE# pulse in the command sequence ( prior to

the program or erase operation), and during the sec-

tor erase time-out. During an Embedded Program or

Erase algorithm operation, successive read cycles to

any address cause DQ6 to toggle. The system may

use either OE# or CE# to control the read cycles.

When the operation is complete, DQ6 stops tog-

gling.

The system can use DQ6 and DQ2 together to

determine whether a sector is actively erasing or is

ing (that is, the Embedded Erase algorithm is in

progress), DQ6 toggles. When the device enters the

Erase Suspend mode, DQ6 stops toggling. How-

ever, the system must also use DQ2 to determine

which sectors are erasing or erase-suspended.

Alternatively, the system can use DQ7(see the sub-

section on DQ7:Data# Polling). DQ6 also toggles

during the erase-suspend-program mode, and stops

toggling once the Embedded Program algorithm is

complete.

Fig. 12 shows the toggle bit algorithm. Fig. 25 in the

“AC Characteristics” section shows the toggle bit

timing diagrams. Fig. 26 shows the differences

between DQ2 and DQ6 in graphical form. See also

the subsection on DQ2 : (Toggle Bit II).

2. DQ7 should be rechecked even if DQ5 = “1” because

DQ7 may change simultaneously with DQ5

Figure 11. Data# Polling Algorithm

Toggling on the Protected Sectors

After an erase command sequence is written, if all

sectors selected for erasing are protected, DQ6 tog-

gles for approximately 1.8us, then returns to reading

array data. If not all selected sectors are protected,

the Embedded Erase algorithm erases the unpro-

tected sectors, and ignores the selected sectors that

are protected. If a program address falls within a

protected sector, DQ6 toggles for approximately

250ns after the program command sequence is writ-

ten, then returns to reading array data.

RY/BY# ( READY/BUSY# )

The RY/BY# is a dedicated, open-drain output pin

which indicates whether an Embedded Algorithm is

in progress or complete. The RY/BY# status is valid

after the rising edge of the final WE# pulse in the

command sequence. Since RY/BY# is an open-

drain output, several RY/BY# pins can be tied

together in parallel with a pull-up resistor to Vcc. If

the output is low (Busy), the device is actively eras-

ing or programming. (This includes programming in

the Erase Suspend mode.) If the output is high

(Ready), the device is in the read mode, the

standby mode, or in the erase-suspend-read mode.

Table 10 shows the outputs for RY/BY#.

DQ2 ( TOGGLE BIT II )

The “Toggle Bit II” on DQ2, when used with DQ6,

indicates whether a particular sector is actively eras-

ing (that is, the Embedded Erase algorithm is in

progress), or whether that sector is erase-sus-

pended. Toggle Bit II is valid after the rising edge of

the final WE# pulse in the command sequence DQ2

DQ6 ( TOGGLE BIT I )

Toggle Bit I on DQ6 indicates whether an Embed-

ded Program or Erase algorithm is in progress or

complete, or whether the device has entered the

toggles when the system reads at addresses within

those sectors that have been selected for erasure.

(The system may use either OE# or CE# to control

the read cycles.) But DQ2 cannot distinguish

whether the sector is actively erasing or is erase-

suspended. DQ6, by comparison, indicates

whether the device is actively erasing, or is in Erase

Suspend, but cannot distinguish which sectors are

selected for erasure. Thus, both status bits are

required for sector and mode information. Refer to

Table 10 to compare outputs for DQ2 and DQ6. Fig.

12 shows the toggle bit algorithm in flowchart form,

and the section “DQ2: Toggle Bit II” explains the

algorithm. See also the DQ6: Toggle Bit I subsec-

tion. Fig. 25 shows the toggle bit timing diagram.

pared with DQ6.

Refer to Fig. 12 for the following discussion. When-

ever the system initially begins reading toggle bit

status, it must read DQ7-DQ0 at least twice in a row

to determine whether a toggle bit is toggling. Typi-

cally, the 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-DQ0 on the following read cycle. However,

if after the initial two read cycles, the system deter-

mines 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 tog-

gling, since the toggle bit may have stopped tog-

gling just as DQ5 went high. If the toggle bit is no

longer toggling, the device has successfully com-

pleted the program or erase operation. If it is still

toggling, the device did not completed 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 deter-

mines 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, this sys-

tem must start at the beginning of the algorithm

when it returns to determine the status of the opera-

tion (top of Fig. 12).

If additional sectors are selected for erasure, the

entire time-out also applies after each additional

sector erase command. When the time-out period is

complete, DQ3 switches from a “0” to a”1”. If the

time between additional sector erase commands

from the system can be assumed to be less than

50us, the system need not monitor DQ3. See also

the Sector Erase Command Sequence section. After

the sector erase command is written, the system

should read the status of DQ7 (Data# Polling) or

DQ6 (Toggle Bit I) to ensure that the device has

accepted the command sequence, and then read

DQ3. If DQ3 is “1”, the Embedded Erase algorithm

has begun; all further commands (except Erase Sus-

pend) are ignored until the erasure operation is com-

plete. If DQ3 is “0”, the device will accept additional

sector erase commands. To ensure the command

has been accepted, the system software should

check the status of DQ3 prior to and following each

subsequent sector erase command. If DQ3 is high

on the second status check, the last command might

not have been accepted. In Table 10, DQ3 status

operation is well defined and summarized with other

status bits, DQ7, DQ6, DQ5, and DQ2.

DQ5 ( EXCEEDED TIMING LIMITS )

DQ5 indicates whether the program or erase time

has exceeded a specified internal pulse count limit.

Under these conditions DQ5 produces a “1”, indi-

cating that the program or erase cycle was not suc-

cessfully completed. The device may output a “1”

on DQ5 if the system tries to program a “1” to a

location that was previously programmed to “0”

Only an erase operation can change a “0” back to a

“1”. Under this condition, the device halts the opera-

tion, and when the timing limit has been exceeded,

DQ5 produces a ”1”. Under both these conditions,

the system must write the reset command to return

to the read mode.

DQ3 ( SECTOR ERASE TIMER )

After writing a sector erase command sequence,

the system may read DQ3 to determine whether or

not erasure has begun. (The sector erase time

does not apply to the chip erase command.)

Notes:

1. Typical program and erase times assume the following conditions: 25^oC, 3.0V Vcc, 10,000 cycles. Additionally, programming

typicals assume checkerboard pattern.

2. Under worst case conditions of 90^oC, Vcc = 2.7V, 100,000 cycles.

3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes

program faster than the maximum program times listed.

4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.

5. System-level overhead is the time required to execute the two-or-four-bus-cycle sequence for the program command. See

Table 9 for further information on command definitions.

6. The device has a minimum erase and program cycle endurance of 100,000 cycles

.
