Product Description
The SST 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. SST25VF020
SPI serial flash memories are manufactured with SST’s proprietary, high performance CMOS Super-
Flash Technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability
and manufacturability compared with alternate approaches.
The SST25VF020 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 SST25VF020 device operates with a single 2.7-3.6V power supply.
The SST25VF020 device is offered in an 8-lead SOIC 150 mil body width (SA) package, and in an 8-
contact WSON package. See Figure 2 for the pin assignments.
