Obsolete Device Please contact Microchip Sales for replacement information. 512 Kbit / 1 Mbit / 2 Mbit / 4 Mbit 1.8V SPI Serial Flash SST25WF512 / SST25WF010 / SST25WF020 / SST25WF040 EOL Data Sheet SST25WF512 / SST25WF010 / SST25WF020 / SST25WF040 are members of the Serial Flash 25 Series family and feature a four-wire, SPI-compatible interface that allows for a low pin-count package which occupies less board space and ultimately lowers total system costs. SPI serial flash memory is manufactured with SST proprietary, high performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. Features • Single Voltage Read and Write Operations – 1.65-1.
