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. 2.1 Block Diagram
