SST25WF040BT-40I/SN is a member 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 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.This Serial Flash significantly improve performance and reliability, while lowering power consumption. The device writes (Program or Erase) with a single power supply of 1.65-1.95V. The total energy consumed is a function of the applied voltage, current, and time of application. Since for any given voltage range, the SuperFlash technology uses less current to program and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than alternative flash memory technologies.
