[Alcor Micro, Corp.]

Description
The AU6395 is a single chip controller designed for bridging USB 2.0 to SATA 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, AU6395 is equipped with Alcor’s proprietary automatic speed negotiation (ASN) algorithm. The ASN algorithm allows AU6395 to select optimized operating mode that device can best support a reliable data transfer. 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.
