The 25 series Serial Flash family features 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. The SST25PF040C devices are enhanced with extended operating voltage of 2.3-3.6V. SST25PF040C SPI serial flash memories are manufactured with 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.
Single Voltage Read and Write Operations Serial Interface Architecture High Speed Clock Frequency Hold Pin - Suspend a serial sequence without deselecting the device Write Protection - Enables/Disables the Lock-Down function of the status register Software Write Protection - Write protection through Block-Protection bits in status register Temperature Range -40°C to +85°C
