The SST26WF064C Serial Quad I/O (SQI) flash device utilizes a 4-bit multiplexed I/O serial interface to boost performance while maintaining the compact form factor of standard serial flash devices. SST26WF064C also supports full command-set compatibility to traditional Serial Peripheral Interface (SPI) protocol. Operating at frequencies reaching 104 MHz, the SST26WF064C enables minimum latency execute-in-place (XIP) capability without the need for code shadowing on an SRAM. The SST26WF064C writes (Program or Erase) with a single power supply of 1.65-1.95V and significantly lower power consumption. The device’s low power consumption makes it the ideal choice for wireless and any battery powered devices. Further benefits are achieved with SST’s proprietary, high-performance CMOS SuperFlash® technology, which significantly improves performance and reliability.
