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 tun-
neling injector attain better reliability and manufacturability
compared with alternate approaches. The SST39LF512/
010/020/040 devices write (Program or Erase) with a 3.0-
3.6V 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 low-
ering power consumption. They inherently use less energy
during Erase and Program than alternative flash technolo-
gies. 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 oper-
ation 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 indi-
cate the completion of Program operation. 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, 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 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 surface mount requirements, the SST39LF512/
010/020/040 and SST39VF512/010/020/040 devices are
offered in 32-lead PLCC and 32-lead TSOP packages. The
SST39LF/VF010 and SST39LF/VF020 are also offered in
a 48-ball TFBGA package. See Figures 1, 2, 3, and 4 for
pin assignments.
The SST39LF512/010/020/040 and SST39VF512/010/
020/040 devices are suited for applications that require
convenient and economical updating of program, configu-
ration, or data memory. For all system applications, they
