1. Introduction
1.1 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.
1.2 Features
ꢀSupports USB 2.0 specification and USB Device Class Definition for Mass
Storage, Bulk-Transport V1.0.
ꢀSupport SATA 1.5G/3.0G Speed Negotiation
ꢀSupport SATAII Asynchronous Signal Recovery (Hot Plug) feature.
ꢀSupport 480Mbps High Speed (HS) and 12Mbps Full Speed USB operation.
ꢀSupports SATA specification Revision 2.5.
ꢀSupport ATA/ATAPI LBA48 bit addressing mode.
ꢀHardware DMA engine integrated inside for performance enhancement
ꢀWorks with default device driver from ME/2000/XP and Mac OS.
ꢀBuilt in 3.3V to 1.8V Voltage Regulator.
ꢀOne spared LED pin for disk access indication
