1. Introduction
1.1 Description
The AU6320 is a single chip integrated USB 2.0 multimedia card reader controller that enables PC/DVD/Printer to read/write CF (Conpact Flash) widely used in digital camera, cell phone, PDA and MP3 player to store digital photos and compressed music. Performance of AU6320 is maximized by implementing the latest and fastest card specification available form the industry. The AU6320 is designed in shared pin architecture to meet cost and space regulate for Notebook end reunite.
1.2 Features
Support USB V2.0 specification and USB Device Class Definition for Mass Storage, Bulk-Transport V1.0 Support CF compatible flash card, including Micro Drive (CF type II). Support CF 4.0 Ultra DMA mode. Hardware DMA engine integrated for performance enhancement. Work with default driver from Windows ME/2000/XP/Vista and Mac OS X; Windows 98/2000(SP1/SP2) and Mac OS 9 are supported by vendor driver from Alcor. Ping-pong FIFO implementation for concurrent bus operation Support multiple sectors transfer optimize performance Support slot-to-slot read/write operation Support Dynamic Icon Utility Support LED for bus operating indication Power switch integrated to reduce production BOM cost 30MHz 8051 CPU Built in 3.3V to 1.8V regulator Runs at 12MHz crystal Available in 48-pin LQFP package
