The MT25Q is a high-performance multiple input/output serial Flash memory device manufactured on 45nm NOR technology. It features a high-speed SPI-compatible bus interface, execute-in-place (XIP) functionality, advanced write protection mechanisms, and extended address access. Innovative, high-performance, dual and quad input/ output commands enable double or quadruple the transfer bandwidth for READ and PROGRAM operations.
