Product Summary

The SST25VF040-80-4I-S2AE is a SPI serial flash memory which features a four-wire, SPI-com-patible interface that allows for a low pin-count package occupying less board space and ultimately lowering total system costs. The SST25VF040-80-4I-S2AE is manufactured with SST’s proprietary, high perfor-mance CMOS SuperFlash Technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches.
