Introduction
The ST72682 is a USB 2.0 high-speed Flash drive controller. The USB 2.0 high-speed interface includes PHY and function and supports USB 2.0 mass storage device class.
The Mass storage controller interface (MSCI), combined with the Reed-Solomon encoder/decoder on-the-fly correction (4 bytes on 512-byte data blocks), provides a flexible high transfer rate solution for interfacing a wide of range NAND Flash memory devices.
