PRODUCT DESCRIPTION
The SST39WF800B is a 512K x16 CMOS Multi-Purpose
Flash (MPF) manufactured with SST proprietary, high-per-
formance CMOS SuperFlash technology. The split-gate
cell design and thick-oxide tunneling injector attain better
reliability and manufacturability compared to alternate
approaches. The SST39WF800B writes (Program or
Erase) with a 1.65-1.95V power supply. This device con-
forms to JEDEC standard pin assignments for x16 memo-
ries.
The SST39WF800B features high-performance Word-Pro-
gramming which provides a typical Word-Program time of
28 µsec. It uses Toggle Bit or Data# Polling to detect the
completion of the Program or Erase operation. On-chip
hardware and software data protection schemes protects
against inadvertent writes. Designed, manufactured, and
tested for a wide spectrum of applications, the
SST39WF800B is offered with a guaranteed typical endur-
ance of 100,000 cycles. Data retention is rated at greater
than 100 years.
The SST39WF800B is suited for applications that require
convenient and economical updating of program, configu-
ration, or data memory. It significantly improves perfor-
mance and reliability of all system applications while
lowering power consumption. It inherently uses less energy

during Erase and Program than alternative flash technolo-
gies. When programming a flash device, the total energy
consumed is a function of the applied voltage, current, and
time of application. For any given voltage range, Super-
Flash technology uses less current to program and has a
shorter erase time; therefore, the total energy consumed
during any Erase or Program operation is less than alterna-
tive flash technologies. These devices also improve flexibil-
ity while lowering the cost for program, data, and
configuration storage applications.
SuperFlash technology provides fixed Erase and Program
times independent of the number of Erase/Program cycles
that have occurred. Consequently, 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 SST39WF800B
is offered in a 48-ball TFBGA package and a 48-ball Micro-
Package. See Figure 3 and Figure 2 for pin assignments.
