Introduction 1.1 Description The AU6366 is a single chip integrated USB 2.0 multimedia card reader controller that enables PC/DVD/Printer to read/write various type of flash media cards. Flash media cards such as CF, SMC, XD, SD, MMC, Memory Stick are widely used in digital camera, cell phone, PDA and MP3 player to store digital photos and compressed music. Performance of AU6366 is maximized by implementing the latest and fastest card specification available form the industry. The AU6366 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/MD/SD/MMC/MS/MS_Pro/MS_Duo/xD/SMC compatible flash card Support the latest flash card specification: CF 3.0 (16-bit IDE mode), SD1.1 (HS-SD), MMC4.0 (8-bit), MSPro parallel mode (4-bit), xD 1.2 Hardware DMA engine integrated for performance enhancement Work with default driver from Windows ME/2000/XP 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 2.5V regulator Run at 12MHz crystal Available in 48-pin LQFP package AU6366 USB 2.0 Single LUN Multiple Flash Card Reader Controller V1.03W 1 2. Application Block Diagram The following application drawing demonstrates a typical card reader block diagram using AU6366. By connecting one card reader to a desktop or notebook PC through USB bus, the AU6366 becomes a bus-powered, high speed USB card reader, which can be used as a bridge for data transfer between Desktop PC and Notebook PC.
