ST72681 USB 2.0高速闪存盘控制器

The ST72681 is a USB 2.0 high-speed Flash drive controller. The USB 2.0 high-speed interface including PHY and function 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-byte on 512-byte data blocks) provides a flexible,high transfer rate solution for interfacing a wide of range NAND Flash memory device types.

The internal 60 MHz PLL driven by the 12 MHz oscillator is used to generate the 480 MHz frequency for the USB 2.0 PHY.The ST7 8-bit CPU runs the application program from the internal ROM and RAM. USB data and patch code are stored in internal RAM. I/O ports provide functions for EEPROM connection, LEDs and write protect switch control.The internal 3.3 to 1.8 V voltage regulator provides the 1.8 V supply voltage to the digital part of the circuit.
