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. SST25VF020/040 SPI serial flash memo-
ries 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 SST25VF020/040 devices significantly improve per-
formance, while lowering power consumption. The total
energy consumed is a function of the applied voltage, cur-
rent, 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
SST25VF020/040 devices operate with a single 2.7-3.6V
power supply.
The SST25VF020 devices are offered in an 8-lead SOIC
150 mil body width (SA) package. The SST25VF040
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.
