PRODUCT DESCRIPTION
The SST39LF512/010/020/040 and SST39VF512/010/
020/040 are 64K x8, 128K x8, 256K x8 and 5124K x8
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 SST39LF512/
010/020/040 devices write (Program or Erase) with a 3.03.6V power supply. The SST39VF512/010/020/040
devices write with a 2.7-3.6V power supply. The devices
conform to JEDEC standard pinouts for x8 memories.
significantly improves performance and reliability, while lowering power consumption. They inherently use less energy
during Erase and Program than alternative flash technologies. 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.
Featuring high performance Byte-Program, the
SST39LF512/010/020/040 and SST39VF512/010/020/
040 devices provide a maximum Byte-Program time of 20
µsec. These devices use Toggle Bit or Data# Polling to indicate the completion of Program 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, they
are offered with a guaranteed typical endurance of 10,000
cycles. Data retention is rated at greater than 100 years.
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.
The SST39LF512/010/020/040 and SST39VF512/010/
020/040 devices are suited for applications that require
convenient and economical updating of program, configuration, or data memory. For all system applications, they
