PRODUCT DESCRIPTION

The SST29SF020/040 and SST29VF020/040 are 256K

x8 / 512K x8 CMOS Small-Sector Flash (SSF) manufac-

tured with SST’s proprietary, high-performance CMOS

SuperFlash technology. The split-gate cell design and

thick-oxide tunneling injector attain better reliability and

manufacturability compared with alternate approaches.

The SST29SF020/040 devices write (Program or Erase)

with a 4.5-5.5V power supply. The SST29VF020/040

devices write (Program or Erase) with a 2.7-3.6V power

supply. These devices conform to JEDEC standard pin

assignments for x8 memories.

ory. For all system applications, they significantly improve

performance and reliability, while lowering power consump-

tion. They inherently use less energy during Erase and

Program than alternative flash technologies. The total

energy consumed is a function of the applied voltage, cur-

rent, and time of application. Since for any given voltage

range, the SuperFlash technology uses less current to pro-

gram and has a shorter erase time, the total energy con-

sumed during any Erase or Program operation is less than

alternative flash technologies. They also improve flexibility

while lowering the cost for program, data, and configuration

storage applications.

Featuring high performance Byte-Program, the

SST29SF020/040 and SST29VF020/040 devices pro-

vide a maximum Byte-Program time of 20 µsec. To protect

against inadvertent write, they have on-chip hardware and

Software Data Protection schemes. Designed, manufac-

tured, and tested for a wide spectrum of applications, these

devices are offered with a guaranteed endurance of at least

10,000 cycles. Data retention is rated at greater than 100

years.

The SuperFlash technology provides fixed Erase and Pro-

gram times independent of the number of Erase/Program

cycles that have occurred. Therefore, the system software

or hardware does not have to be modified or de-rated as is

necessary with alternative flash technologies, whose Erase

and Program times increase with accumulated Erase/Pro-

gram cycles.

To meet high density, surface mount requirements, the

SST29SF020/040 and SST29VF020/040 devices are

offered in 32-lead PLCC and 32-lead TSOP packages. The

pin assignments are shown in Figures 2 and 3.

The SST29SF020/040 and SST29VF020/040 devices

are suited for applications that require convenient and eco-

nomical updating of program, configuration, or data mem-
