PRODUCT DESCRIPTION
The SST serial flash family features a four-wire, SPI-
compatible interface that allows for a low pin-count pack-
age occupying less board space and ultimately lowering
total system costs. SST25VF040 SPI serial flash memo-
ries are manufactured with SST 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 SST25VF040 device significantly improves perfor-
mance, 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
SST25VF040 device operates with a single 2.7-3.6V
power supply.
The SST25VF040 device is offered in an 8-lead SOIC 200
mil body width (S2A) package and in an 8-contact WSON
package. See Figure 2 for the pin assignments.
