PRODUCT DESCRIPTION
The SST39SF010A/020A/040 are 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 SST39SF010A/020A/040 devices write
(Program or Erase) with a 4.5-5.5V power supply. The
SST39SF010A/020A/040 devices conform to JEDEC stan-
dard pinouts for x8 memories.
Featuring
high
performance
Byte-Program,
the
SST39SF010A/020A/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, these devices are offered with a guaranteed
typical endurance of 10,000 cycles. Data retention is rated
at greater than 100 years.
The SST39SF010A/020A/040 devices are suited for appli-
cations that require convenient and economical updating of
program, configuration, or data memory. For all system
applications, they significantly improve performance and
reliability, while lowering power consumption. They inher-
ently use less energy during erase and program than alter-
native flash technologies. The total energy consumed is a
function of the applied voltage, current, and time of applica-
tion. 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 technolo-
gies. These devices also improve flexibility while lowering
the cost for program, data, and configuration storage appli-
cations.
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
SST39SF010A/020A/040 are offered in 32-lead PLCC and
32-lead TSOP packages. A 600 mil, 32-pin PDIP is also
available. See Figures 1, 2, and 3 for pin assignments.
