AU6337 USB 2.0 SD/MMC/MS Single/Dual LUN Flash Memory Card Reader V1.00W 1
1. Introduction
1
1. .1 1 D De es sc cr ri ip pt ti io on n
AU6337 is an USB2.0 high-speed transmission controller, which is designed as a
bridge between USB and SD/MS compatible flash card interface, such as SD, HS-SD,
MMC, HS-MMC, RS-MMC, MMCmicro, MS, MS Pro and MS Duo…etc. AU6337 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 AU6337, users can transfer digital data between flash memory card and PC
or other electronic devices.
AU6337 inherits the high-performance and cost-efficiency character from Alcor’s
products, included power switch integration, dynamic icon utility support, and DMA
engine integration.

2. Application Block Diagram
The following application drawing demonstrates a typical card reader block diagram
using AU6337. By connecting one card reader to a desktop or notebook PC through
USB bus, the AU6337 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.
