PRODUCT DESCRIPTION
The SST49LF00xA flash memory devices are designed
to be read-compatible with the Intel 82802 Firmware Hub
(FWH) device for PC-BIOS application. It provides pro-
tection for the storage and update of code and data in
addition to adding system design flexibility through five
general purpose inputs. Two interface modes are sup-
ported by the SST49LF00xA: Firmware Hub (FWH)
Interface Mode for In-System programming and Parallel
Programming (PP) Mode for fast factory programming of
PC-BIOS applications.
The SST49LF00xA flash memory devices are manufac-
tured with SST’s proprietary, high performance Super-
Flash Technology. The split-gate cell design and thick
oxide tunneling injector attain better reliability and manu-
facturability compared with alternate approaches. The
SST49LF00xA devices significantly improve performance
and reliability, while lowering power consumption. The
SST49LF00xA devices write (Program or Erase) with a
single 3.0-3.6V power supply. It uses less energy during
Erase and Program than alternative flash memory tech-
nologies. The total energy consumed is a function of the
applied voltage, current and time of application. Since for
