SST26WF040B Datasheet PDF - Microchip Technology

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. SST26WF040B/040BA and SST26WF080B/ 080BA 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.
