1.0 Introduction
1.1 Description
The AU6370 is an integrated single chip memory card reader controller specially
designed for notebook, hand-held and other PC peripheral devices, which require
fewer components for small PCB area. It supports a widely used flash memory card
such as CF, MD, SMC, xD Picture Card, MS, MS Pro, MS Duo, SD and MMC. It can be
used as removable storage disks in enormous data exchange applications between
PC and PC or PC and various consumer electronic appliances.
The AU6370 reads digital content saved on memory card that user captured with the
portable device such as notebook, digital camera, MP3 player, PDA and mobile
phone… etc. In addition, AU6370 allows user to transfer information such as data,
graphics, texts or digital images from one electronic device to another quickly and
easily. Furthermore, AU6370 integrates power switch function; manufacturers can
use fewer components in their product design.
With AU6370, user’s experience will be also further enhanced by the Plug-and-Play
nature built into latest operation systems such as Windows 2000/XP and Mac OS X.
1.2 Features
Support USB v2.0 specification and USB Device Class Definition for Mass
Storage, Bulk-Transport v1.0
Support CF/MD, SDHC/SD/MMC, MS/MS PRO/MS ROM/MS Duo AND xD/SMC
specification
Work with default driver from Windows ME, Windows XP, and Mac OS X.
Windows 98, Windows 2000 are supported by vendor AP (The AP included
both win98 and 2000 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 auto-detecting slot with card inserted on Win 2000 without driver.
Capable of handing 4 sets of built-in PID, VID and strings to minimize
inventory control and improve lead production lead-time.
Support LED for bus activity indication.
Each slot can be enables/disabled by 5 independent pins to fit all the
different card readers’ combination requirement.
Runs at 30MHz, built-in 480 MHz PLL
Built-in 3.3V to 1.8V regulator

2.0 Application Block Diagram
The following application drawing demonstrates a typical card reader block diagram
using AU6370. By connecting one card reader to a desktop or notebook PC through
USB bus, the AU6370 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.
