Introduction 1.1 Description AU6336 is an USB2.0 high-speed transmission controller, which is designed as a bridge between USB and SD compatible flash card interface, such as SD, HS-SD, MMC, HS-MMC, RS-MMC, MMCmicro…etc. AU6336 can read digital contents stored on memory card designed to cover a wide area of applications such as digital cameras, PDAs, MP3 players and smart phones…etc. AU6336 inherits the high-performance and cost-efficiency character from Alcor’s products, included power switch integration, dynamic icon utility support, and DMA engine integration. 1.2 Features Support USB V2.0 specification and USB Device Class Definition for Mass Storage, Bulk-Transport V1.0 Support SD/MMC compatible flash card Support the latest flash card specification: SD2.0 (SDHC), MSPro parallel mode (4-bit) Alcor 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. Compliant to xD 1.2 spec. Ping-pong FIFO implementation for concurrent bus operation. Support multiple sectors transfer optimize performance Support Dynamic Icon Utility Support LED for bus operating indication Power switch integrated to reduce production BOM cost 5 3.3 and 3.3 1.8V regulators built in 28-SSOP package for SD/MMC 24-QFN package for SD/MMC AU6336 USB2.0 SD/MMC Single LUN Card Reader Controller V1.00W 1 2. Application Block Diagram Following application diagram demonstrates a typical card reader using the AU6336 chip. By connecting the card reader to a desktop or notebook PC through USB bus, the AU6336 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.
