Description

General part information

SST25VF040B Series

The 25 series Serial Flash family features a four-wire, SPIcompatible interface that allows for a low pin-count package which occupies less board space and ultimately lowers total system costs. The SST25VF040B devices are enhanced with improved operating frequency for lower power consumption. SST25VF040B 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 reliability and manufacturability compared with alternate approaches.
