The SST25VF010A-33-4I-SAE is a 1Mbit SPI 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. The SPI serial flash memory is manufactured with SST proprietary, high performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunnelling injector attain better reliability and manufacturability compared with alternate approaches. This device significantly improves performance, while lowering power consumption. 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. This device operates with a single 2.7 to 3.6V power supply.
