Introduction 1.1 Description The AU6371 is a highly integrated single chip media USB card reader controller that supports all popular form factor digital cards, such as CF, MD, SMC, SD, MMC, MS, MS Pro, MS Duo and XD. In addition to the small form factor and low BOM cost the solution also implement high performance operation a sophisticated DMA engine. With the compliance with USB Storage Class V1.0, AU6371 not only exhibits wide acceptance in various OS platforms, its multiple slot design further enables the solution adapters become the content exchange center for mobile media. It 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. With the AU6371, users can transfer digital data between flash memory card and PC or these electronic devices. The AU6371 used 48 pin package specifically designed for small foot print application, such as Note book and printer. In addition to its high performance and outstanding compatibility, the solution of AU6371 comes with a user-friendly utility to enhance users' experience. Moreover, AU6371 integrates power switch to reduce the overall BOM cost. 1.2 Features Supports USB 2.0 specification and USB Device Class Definition for Mass Storage, Bulk-Transport V1.0 Supports CF/MD/SD/MMC/MS/MS_Pro/MS_Duo/xD/SMC compatible flash card in 48 pin package Supports the latest flash card specification: CF 4.0 (with True IDE PIO mode 6), SD 2.0 (SDHC), MMC 4.2 (8-bit), MS Pro parallel mode (4-bit), xD 1.2, SMC2003. A built-in DMA engine for data transmission performance enhancement Work with default driver from Windows ME/2000/XP and Mac OS X; Vendor device driver from Alcor Micro are available to run under Windows 98/2000(SP1/SP2) and Mac OS 9 Ping-pong FIFO implementation for concurrent bus operation Supports multiple sector burst transfer for optimized performance Supports Dynamic Icon Utility to enhance user experience Supports LED for bus activities indication Power switch integrated to reduce production BOM cost Support power saving mode for notebook when no card inserted.
