FEATURES:

• Firmware Hub for Intel 8xx Chipsets

• 8 Mbit SuperFlash memory array for code/data

• Flexible Erase Capability

• Single 3.0-3.6V Read and Write Operations

• Superior Reliability

• Low Power Consumption

• Fast Sector-Erase/Byte-Program Operation

PRODUCT DESCRIPTION

The SST49LF008A flash memory devices are designed to

be read-compatible with the Intel 82802 Firmware Hub

(FWH) device for PC-BIOS application. These devices pro-

vide protection 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 SST49LF008A: Firmware Hub (FWH) Inter-

face mode for in-system programming and Parallel

Programming (PP) mode for fast factory programming of

PC-BIOS applications.

The SST49LF008A flash memory devices are manufac-

tured with SST’s proprietary, high performance SuperFlash

technology. The split-gate cell design and thick-oxide tun-

neling injector attain better reliability and manufacturability

compared with alternate approaches. The SST49LF008A

devices significantly improve performance and reliability,

while lowering power consumption.

The SST49LF008A devices write (Program or Erase) with

a single 3.0-3.6V power supply. They use less energy dur-

ing 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

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 memory technologies.

The SST49LF008A products provide a maximum Byte-

Program time of 20 µsec. The entire memory can be

erased and programmed byte-by-byte typically in 15 sec-

onds when using status detection features such as Toggle

Bit or Data# Polling to indicate the completion of Program

operation. The SuperFlash technology provides fixed Erase

and Program times independent of the number of Erase/

Program cycles performed. Therefore the system software
