AN1475 Developing an ST7265x Mass Storage Application
The document describes a solution for developing a USB Mass Storage application on the ST7265x microcontroller. It includes a generic USB Mass Storage Layer (MSL) compliant with the USB Mass Storage Class and dedicated Media Access Layer (MAL) add-ins for various storage media types such as Flash memory cards, hard disk drives, CompactFlash, SmartMedia, MultiMediaCard, and Sony Stick.
The software architecture is modular to allow users to easily replace or customize modules. The note details the project file structure, defines the maximum number of logical units (LUNs), and provides specific instructions on media selection and hardware interface pin configurations for different storage devices.
