Product Description

SST25WF020A 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

manufacturability compared with alternate approaches.

This Serial Flash significantly improves 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 consumed

during any Program or Erase operation is less

than alternative Flash memory technologies.
