The SQI FLASH Click Board™ is based on the SST26VF064B, a 64 Mbit Serial Quad I/O flash device from Microchip. The chip utilizes a 4-bit multiplexed I/O serial interface to boost the performance. The Click Board™ is a very fast solid-state, non-volatile data storage medium, that can be electrically erased and reprogrammed. Operating at 104 MHz, the SST26VF064B enables minimum latency execute-in-place (XIP) capability, without the need for code shadowing.
