Mt25q is a high-performance multi input / output serial flash memory device. It has high-speed SPI compatible bus interface, local execution (XIP) function, advanced write protection mechanism and extended address access function. Innovative, high-performance, dual and Quad I / O commands double or quadruple the transmission bandwidth of read and program operations.

The device provides an advanced security protection scheme. Each sector can be locked independently through volatile or nonvolatile locking function. The non-volatile locking configuration can also be locked and password protected.
