SST25VF040 - SST

SST25VF040 2 Mbit / 4 Mbit SPI Serial Flash

The SST serial flash family features a four-wire, SPIcompatible interface that allows for a low pin-count package occupying less board space and ultimately lowering total system costs. SST25VF040 SPI serial flash memories are manufactured with SST proprietary, high performance CMOS SuperFlash Technology. The split-gate cell design and thick-oxide tunneling i.
