2 Mbit SPI Serial Flash
SST25LF020A
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. SST25LF020A SPI serial flash memory is manufactured with
SST proprietary, high performance CMOS SuperFlash Technology. The split-gate
cell design and thick-oxide tunneling injector attain better reliability and manufac-
turability compared with alternate approaches.
Not recommended for new designs.

Product Description
SST’s 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.
SST25LF020A SPI serial flash memories are manufactured with SST’s proprietary, high perfor-
mance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector
attain better reliability and manufacturability compared with alternate approaches.
The SST25LF020A devices significantly improve 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 SST25LF020A devices operate with a single
3.0-3.6V power supply.
The SST25LF020A devices are 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.
