Product Description

SST25WF040B 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 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 consumed

during any Erase or Program operation is less

than alternative flash memory technologies.
