GENERAL DESCRIPTION

The

)729F040B

is a 4 Mbit, 5.0 volt-only Flash mem-

ory organiVed as 524,288 Kbytes of 8 bits each. The

512 Kbytes of data are divided into eight sectors of 64

Kbytes each for flexible erase capability. The 8 bits of

data appear on DQ0–DQ7. The

)729F040B

is offered

in 32-pin PLCC, TSOP, and PDIP packages. This device

is designed to be programmed in-system with the stan-

dard system 5.0 volt V

supply. A 12.0 volt V

is not

required for write or erase operations. The device can

also be programmed in standard EPROM programmers.

This device is manufactured using 0.32 μm pro-

cess technology, and offers all the features and

benefits of the

)729F040,

which was manufactured

using 0.5 μm process technology. In addtion, the

)729F040B

has a second toggle bit, DQ2, and also of-

fers the ability to program in the Erase Suspend mode.

The standard

)729F040B

offers access times of 55,

70, 90, 120, and 150 ns, allowing high-speed micropro-

cessors to operate without wait states. To eliminate bus

contention the device has separate chip enable (CE#),

write enable (WE#) and output enable (OE#) controls.

The device requires only a

single 5.0 volt power sup-

ply

for both read and write functions. Internally

generated and regulated voltages are provided for the

program and erase operations.

The device is entirely command set compatible with the

JEDEC single-power-supply Flash standard.

Com-

mands are written to the command register using

standard microprocessor write timings. Register con-

tents serve as input to an internal state-machine that

controls the erase and programming circuitry. Write cy-

cles also internally latch addresses and data needed

for the programming and erase operations. Reading

data out of the device is similar to reading from other

Flash or EPROM devices.

Device programming occurs by executing the program

command sequence. This initiates the

Embedded

Program

algorithm—an internal algorithm that auto-

matically times the program pulse widths and verifies

proper cell margin.

Device erasure occurs by executing the erase com-

mand sequence. This initiates the

Embedded Erase

algorithm—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 host system can detect whether a program or

erase operation is complete by reading the DQ7 (Data#

Polling) and DQ6 (toggle)

status bits.

After a program

or erase cycle has been completed, the device is ready

to read array data or accept another command.

The

sector erase architecture

allows memory sectors

to be erased and reprogrammed without affecting the

data contents of other sectors. The device is fully

erased when shipped from the factory.

Hardware data protection

measures include a low

detector that automatically inhibits write opera-

tions during power transitions. The

hardware sector

protection

feature disables both program and erase

operations in any combination of the sectors of mem-

ory. This can be achieved via programming equipment.

The

Erase Suspend

feature enables the user to put

erase on hold for any period of time to read data from,

or program data to, any sector that is not selected for

erasure. True background erase can thus be achieved.

The system can place the device into the

standby mode.

Power consumption is greatly reduced in this mode.

2XU

Flash technology combines years of Flash

memory manufacturing experience to produce the

highest levels of quality, reliability and cost effective-

ness. The device electrically erases all bits within a

sector simultaneously via Fowler-Nordheim tunneling.

The data is programmed using hot electron injection.
