PRODUCT DESCRIPTION
The SST39LF200A/400A/800A and SST39VF200A/400A/
800A devices are 128K x16 / 256K x16 / 512K x16 CMOS
Multi-Purpose Flash (MPF) manufactured 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 SST39LF200A/400A/800A
write (Program or Erase) with a 3.0-3.6V power supply. The
SST39VF200A/400A/800A write (Program or Erase) with a
2.7-3.6V power supply. These devices conform to JEDEC
standard pinouts for x16 memories.
Featuring high performance Word-Program, the
SST39LF200A/400A/800A and SST39VF200A/400A/
800A devices provide a typical Word-Program time of 14
µsec. The devices use Toggle Bit or Data# Polling to detect
the completion of the Program or Erase operation. To protect against inadvertent write, they have on-chip hardware
and software data protection schemes. Designed, manufactured, and tested for a wide spectrum of applications,
these devices are offered with a guaranteed endurance of
10,000 cycles. Data retention is rated at greater than 100
years.
The SST39LF200A/400A/800A and SST39VF200A/400A/
800A devices are suited for applications that require convenient and economical updating of program, configuration,
or data memory. For all system applications, they signifi-

cantly improve performance and reliability, while lowering
power consumption. They inherently use less energy during Erase and Program than alternative flash technologies.
When programming a flash device, the total energy consumed is a function of the applied voltage, current, and
time of application. Since for any given voltage range, the
SuperFlash technology uses less current to program and
has a shorter erase time, the total energy consumed during
any Erase or Program operation is less than alternative
flash technologies. These devices also improve flexibility
while lowering the cost for program, data, and configuration
storage applications.
The SuperFlash technology provides fixed Erase and Program 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/Program cycles.
To meet surface mount requirements, the SST39LF200A/
400A/800A and SST39VF200A/400A/800A are offered in
both 48-lead TSOP packages and 48-ball TFBGA packages. See Figures 1 and 2 for pinouts.
