A Microchip Technology Company 512 Kbit SPI Serial Flash SST25VF512 Data Sheet SST serial flash family features a four-wire, SPI-compatible interface that allows for a low pin-count package occupying less board space and ultimately lowering total system costs. SST25VF512 SPI serial flash memory is manufactured with SST's proprietary, high-performance CMOS SuperFlash technology. The splitgate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. Features • Single 2.7-3.6V Read and Write Operations • Serial Interface Architecture – SPI Compatible: Mode 0 and Mode 3 • 20 MHz Max Clock Frequency • Superior Reliability – Endurance: 100,000 Cycles (typical) – Greater than 100 years Data Retention • Lo [ ... ]
