ST7267R8 USB 2.0高速大容量存储的微控制器

Storage microcontroller. The USB 2.0 highspeed interface including PHY and function supports USB 2.0 Mass Storage Device Class.The Mass Storage Controller Interface (MSCI) features a 16-bit RISC ALU core combined with the Reed-Solomon Encoder/Decoder on-the-fly correction on 512 data byte blocks provides a flexible,high transfer rate solution for interfacing all types of NAND Flash memory devices.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 CPU runs the application program from the internal ROM and RAM. USB data and patch code are stored in internal RAM. The I/O ports provide functions for EEPROM connection,LEDs and write protect switch control.The internal 3.3V to 1.8V voltage regulator provides the 1.8V supply voltage to the digital part of the circuit. 1.1 Related Documentation For details on the programming model of the ST7 CPU and the MSCI, please refer to the following manuals:
