From Microchip the SST26WFxxxB family of products are Serial Quad I/O (SQI) Flash Memory devices available in 4-, 8- and 16-bit variants. These devices support full command-set compatibility with Serial Peripheral Interface (SPI) protocol and enable minimum latency Execute-in-Place (XIP) capability without the need for code shadowing on an SRAM. The SST26WFxxxB devices exhibit low power consumption, making them suitable for portable battery powered applications.
