Product Description

The Serial Quad I/O™ (SQI™) family of Flash memory

devices features a six-wire, 4-bit I/O interface that allows for

low-power, high-performance operation in a low pin-count

package. SST26VF032B/032BA also support full command-

set compatibility to traditional Serial Peripheral Interface

(SPI) protocol. System designs using SQI Flash

devices occupy less board space and ultimately lower

system costs.

All members of the 26 Series, SQI family are manufactured

with 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.
