AU6391 General Description
The AU6391 is a single chip USB 2.0 to ATA/ATAPI controller. It is used as the primary controller of an external USB 2.0 hard disk or CD/DVD box.
To maximize the data throughput and achieve the best compatibility, the AU6391 is equipped with Alcor's proprietary automatic speed negotiation (ASN) algorithm. The ASN algorithm allows AU6390 to select optimized operating mode that device can best support from PIO mode 0~4 and Ultra DMA mode 2/4.
