1.0 Introduction
1.1 Description
The AU6330 is a highly integrated single chip for USB SD/MMC flash card reader controller. It supports USB2.0 high/full speed transmission via USB port interface to Host PC and 4-bit parallel transmission via SD/MMC interface to flash card. The AU6330 supports USB2.0 Storage Class Specification, Bulk-Transport Protocol. It can read digital content stored in SD/MMC flash card designed to cover a wide area of application such as digital camera, PDA, MP3 player and smart phone...etc. With the AU6330, users can transfer digital data between SD/MMC flash card and PC or these electronic devices.
1.2 Features
Support USB2.0 specification 480Mbps transmission and USB Device Class Definition for Mass Storage, Bulk-Transport V1.0 Integrated USB2.0 Transceiver Macrocell Interface (UTMI) transceiver and Serial Interface Engine (SIE) Support SD card and MMC specification Work with default driver from Windows ME/2000/XP, Mac OS X and Linux kernel 2.4.1 above. Windows 98 & Windows 2000 SP1/2 are supported by vendor driver from Alcor. Ping-pong FIFO implementation for concurrent bus operation Support multiple sectors transfer optimize performance Support optional external EEPROM for USB VID, PID and string customization Capable of handling 8 sets of built-in PID, VID and strings to minimize inventory control and improve production lead time Support LED for bus activity indication. Runs at 30MHz, built-in 480 MHz PLL Built-in to 3.3V to 2.5V regulator
