64 Mbit SPI Serial Dual I/O Flash
A Microchip Technology Company
SST25VF064C
Data Sheet
The SST 25 series Serial Flash family features a four-wire, SPI-compatible inter-
face that allows for a low pin-count package which occupies less board space and
ultimately lowers total system costs. SST25VF064C SPI serial flash memory is
manufactured with SST proprietary, high-performance CMOS SuperFlash tech-
nology. The split-gate cell design and thick-oxide tunneling injector attain better
reliability and manufacturability compared with alternate approaches.
