The Microchip 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. It also supports full command-set compatibility to traditional Serial Peripheral Interface (SPI) protocol. Operating at frequencies reaching 104 MHz, the SST26VF040A enables minimum latency execute-in-place (XIP) capability without the need for code shadowing on an SRAM. The device’s high performance and reliability make it the ideal choice for network appliance, smart home, wireless connectivity, computing, digital TV, smart meter, datacentre, automotive and other industrial applications. Further benefits are achieved with SST’s proprietary, high-performance CMOS Super flash® technology, which significantly improves performance and reliability, and lowers power consumption for high bandwidth, compact designs.
