1.0 Introduction
1.1 Description
The AU6391 is a single chip controller designed for bridgingg USB 2.0 to ATA/ATAPI bus interface. It is used as the primary controller of building an external USB 2.0 hard disk or CD/DVD drives. To maximize the data throughput and achieve the best compatibility, AU6391 is equipped with Alcor's proprietary automatic speed negotiation (ASN) algorithm. The ASN algorithm allows AU6391 to select optimized operating mode that device can best support a reliable data transfer from PIO mode 0~4 and Ultra DMA mode 2/4. The silicon would work with the default device driver from Windows ME, Windows 2000, Windows XP and Mac OS X, however, vendor device driver provided by Alcor Micro would enable the built device working under Windows 98, Windows 2000 (SP1/SP2) and Mac OS 9.
1.2 Features
Supports USB 2.0 specification and USB Device Class Definition for Mass Storage, Bulk-Transport V1.0 Supports ATA/ATAPI-6 specification Revision 1.0 PIO mode 0~4 UDMA mode 2/4 Supports ATA/ATAPI device configured in master or slave mode Supports 48-bit addressing for large capacity hard drive Hardware DMA engine integrated inside for performance enhancement Works with default device driver from Windows ME/2000/XP and Mac OS X. One spared LED pin for disk access indication Built-in voltage regulator 48-pin LQFP package
