PRODUCT DESCRIPTION

SST’s serial flash family features a four-wire, SPI-com-

patible interface that allows for a low pin-count package

occupying less board space and ultimately lowering total

system costs. SST25LF020A/040A SPI serial flash

memories are manufactured with SST’s 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 SST25LF020A/040A devices significantly improve

performance, while lowering power consumption. The

total energy consumed is a function of the applied volt-

age, current, and time of application. Since for any given

voltage range, the SuperFlash technology uses less cur-

rent 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/040A 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. The SST25LF040A

devices are offered in an 8-lead SOIC 200 mil body width

(S2A) package. All densities are offered in the 8-contact

WSON package. See Figure 1 for the pin assignments.
