A Microchip Technology Company
SST's 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 ulti-
mately lowers total system costs. The SST25VF016B devices are enhanced with
improved operating frequency and lower power consumption. SST25VF016B SPI
serial flash memories are manufactured with SST's proprietary, high-performance
CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunnel-
ing injector attain better reliability and manufacturability compared with alternate
approaches.
