# 1.1.13.3 W25 Driver

This driver provides a blocking interface to read, write and erase W25 Flash memory. The driver uses the QMSPI peripheral library to interface with the W25 Flash.

Key Features:

- Supports Multiple variants of the W25 Flash devices

- Supports a single instance of the W25 Flash and a single client to the driver

- Supports Sector/Block/Chip Erase Operations

- Supports writes to random memory address within page boundaries

- The library interface is compliant to the block media interface expected by the Memory Driver. This allows running a file system on the W25 Flash using the Memory Driver and the File System Service

- The library can be used in both Bare-Metal and RTOS environments
