Product Description
The SST 25 series Serial Flash family features 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. SST25VF032B SPI serial flash memories are manufactured with SST’s 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.
The SST25VF032B devices significantly improve performance and reliability, while lowering power
consumption. The devices write (Program or Erase) with a single power supply of 2.7-3.6V for
SST25VF032B. 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 SST25VF032B device is offered in 8-lead SOIC (200 mils) and 8-contact WSON packages.
