AU6391中文资料USB2.0 to ATA/ATAPI Bridge Controller数据手册ALCOR规格书

描述 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
