1.8V Serial Quad I/O (SQI) Flash Memory
SST26WF032
Advance Information
The SST26WF032 Serial Quad I/O™ (SQI™) flash device utilizes a 4-bit mul-
tiplexed I/O serial interface to boost performance while maintaining the com-
pact form factor of standard serial flash devices. Operating at frequencies
reaching 80 MHz, the SST26WF032 enables minimum latency execute-in-
place (XIP) capability without the need for code shadowing on an SRAM. The
device’s high performance and small footprint make it the ideal choice for
mobile handsets, Bluetooth headsets, optical disk drives, GPS applications
and other portable electronic products. Further benefits are achieved with
SST’s proprietary, high-performance CMOS SuperFlash® technology, which
significantly improves performance and reliability, and lowers power consump-
tion for high bandwidth, compact designs.
