PRODUCT DESCRIPTION

The SST27SF256/512/010/020 are a 32K x8 / 64K x8 /

128K x8 / 256K x8 CMOS, Many-Time Programmable

(MTP) low cost flash, manufactured with SST’s proprietary,

high performance SuperFlash technology. The split-gate

cell design and thick oxide tunneling injector attain better

reliability and manufacturability compared with alternate

approaches. These MTP devices can be electrically erased

and programmed at least 1000 times using an external pro-

grammer with a 12 volt power supply. They have to be

erased prior to programming. These devices conform to

JEDEC standard pinouts for byte-wide memories.

Featuring high performance Byte-Program, the

SST27SF256/512/010/020 provide a Byte-Program time of

20 µs. Designed, manufactured, and tested for a wide

spectrum of applications, these devices are offered with an

endurance of at least 1000 cycles. Data retention is rated at

greater than 100 years.

The SST27SF256/512/010/020 are suited for applications

that require infrequent writes and low power nonvolatile

storage. These devices will improve flexibility, efficiency,

and performance while matching the low cost in nonvolatile

applications that currently use UV-EPROMs, OTPs, and

mask ROMs.

To meet surface mount and conventional through hole

requirements, the SST27SF256/512 are offered in 32-lead

PLCC, 32-lead TSOP and 28-pin PDIP packages. The

SST27SF010/020 are offered in 32-pin PDIP 32-lead

PLCC, and 32-lead TSOP packages. See Figures 1, 2, and

3 for pin assignments.

Device Operation

The SST27SF256/512/010/020 are a low cost flash

solution that can be used to replace existing UV-

EPROM, OTP, and mask ROM sockets. These devices

are functionally (read and program) and pin compatible

with industry standard EPROM products. In addition to

EPROM functionality, these devices also support elec-

trical Erase operation via an external programmer. They

do not require a UV source to erase, and therefore the

packages do not have a window.

Read

The Read operation of the SST27SF256/512/010/020 is

controlled by CE# and OE#. Both CE# and OE# have to be

low for the system to obtain data from the outputs. Once

the address is stable, the address access time is equal to

the delay from CE# to output (T

). Data is available at the

output after a delay of T

from the falling edge of OE#,

assuming that CE# pin has been low and the addresses

have been stable for at least T

-T

OE.

When the CE# pin is

high, the chip is deselected and a typical standby current of

10 µA is consumed. OE# is the output control and is used

to gate data from the output pins. The data bus is in high

impedance state when either CE# or OE# is high.
