2 Mbit SPI Serial Flash drives

The SST serial flash family features a four-wire, SPIcompatible  interface that allows for a low pin-count package  occupying less board space and ultimately lowering  total system costs. SST25VF040 SPI serial flash memories  are 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.

The SST25VF040 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. The  SST25VF040 device operates with a single 2.7-3.6V  power supply.

The SST25VF040 device is offered in an 8-lead SOIC 200  mil body width (S2A) package and in an 8-contact WSON  package.
