1. 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

2. Application Block Diagram
The following application drawing demonstrates a typical card reader block diagram
using AU6371. By connecting one card reader to a desktop or notebook PC through
USB bus, the AU6371 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.
