EOL Data Sheet

Product Description

The SST25WF512, SST25WF010, SST25WF020, and SST25WF040 are members of the Serial Flash

25 Series family and feature a four-wire, SPI-compatible interface that allows for a low pin-count pack-

age which occupies less board space and ultimately lowers total system costs. SST25WF512/010/

020/040 SPI serial flash memories are manufactured with SST proprietary, high-performance CMOS

SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reli-

ability and manufacturability compared with alternate approaches.

The SST25WF512/010/020/040 devices significantly improve performance and reliability, while lower-

ing power consumption. The devices write (Program or Erase) with a single power supply of 1.65-

1.95V for SST25WF512/010/020/040. 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.

The SST25WF512/010/020/040 devices are offered in both 8-lead SOIC and an 8-contact WSON

packages. See Figure 2 for the pin assignment.
