Product Description

Data Sheet

The SST 25 series Serial Flash family features a four-wire, SPI-compatible interface that allows for a

low pin-count package which occupies less board space and ultimately lowers total system costs.

SST25VF032B 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 bet-

ter reliability and manufacturability compared with alternate approaches.

The SST25VF032B devices significantly improve performance and reliability, while lowering power

consumption. The devices write (Program or Erase) with a single power supply of 2.7-3.6V for

SST25VF032B. 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 pro-

gram and has a shorter erase time, the total energy consumed during any Erase or Program operation

is less than alternative flash memory technologies.

The SST25VF032B device is offered in 8-lead SOIC (200 mils) and 8-contact WSON packages. See

Figure 2 for pin assignments.
