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.
