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.
Featuring
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 SST29SF020/040 and SST29VF020/040 devices
are suited for applications that require convenient and eco-
nomical updating of program, configuration, or data mem-
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.
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.
