PRODUCT DESCRIPTION

The SST27SF512/010/020 are a 64K x8 / 128K x8 / 256K

x8 CMOS, Many-Time Programmable (MTP) low cost

flash, manufactured with SST’s proprietary, high perfor-

mance 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 pro-

grammed at least 1000 times using an external program-

mer with a 12V power supply. They have to be erased prior

to programming. These devices conform to JEDEC stan-

dard pinouts for byte-wide memories.

Device Operation

The SST27SF512/010/020 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 func-

tionality, these devices also support electrical Erase

operation via an external programmer. They do not

require a UV source to erase, and therefore the pack-

ages do not have a window.

Featuring

high-performance

Byte-Program,

the

Read

SST27SF512/010/020 provide a Byte-Program time of 20

µs. Designed, manufactured, and tested for a wide spec-

trum of applications, these devices are offered with an

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

greater than 100 years.

The Read operation of the SST27SF512/010/020 is con-

trolled 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_CE). Data is available at the out-

put after a delay of T_OEfrom the falling edge of OE#,

assuming that CE# pin has been low and the addresses

have been stable for at least T_CE-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.

The SST27SF512/010/020 are suited for applications that

require infrequent writes and low power nonvolatile stor-

age. 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 SST27SF512 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.
