Product Description

SST25WF080B is a member of the Serial Flash 25

Series family and feature a four-wire, SPI-compatible

interface that allows for a low pin-count package which

occupies less board space and ultimately lowers total

system costs. SPI serial flash memory is manufactured

with proprietary, high-performance CMOS SuperFlash

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

tunneling injector attain better reliability and manufac-

turability compared with alternate approaches.

This Serial Flash significantly improve performance

and reliability, while lowering power consumption. The

device writes (Program or Erase) with a single power

supply of 1.65-1.95V. 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 con-

sumed during any Erase or Program operation is less

than alternative flash memory technologies.

SST25WF080B is offered in 8-lead SOIC and 8-contact

USON packages. See Figure 2-1 for the pin assign-

ments.
