Page 1 GL811USB – USB 2.0 to ATA / ATAPI Bridge Controller 1. General Description The GL811USB is a highly-compatible, low cost USB 2.0 to ATA / ATAPI bridge controller, which integrates Genesys Logic own design high speed UTMI (USB 2.0 Transceiver Macrocell Interface) transceiver. As a one-chip solution which complies with Universal Serial Bus specification rev. 2.0 and ATA / ATAPI-6 specification rev 1.0, the GL811USB can support various kinds of ATA / ATAPI device. There are totally 4 endpoints in the GL811USB controller, Control (0), Bulk In (1), Bulk Out (2), and Interrupt (3). By complies with the USB Storage Class specification ver.1.0 (Bulk only protocol), the GL811USB can support not only plug and play but also Windows XP/ 2000/ ME default driver. The GL811USB uses 12MHz crystal and slew-rate controlled pads to reduce the EMI issue. With 48-pin LQFP (9mmX9mm) package, the GL811USB is the best cost/ performance solution to fit different situations in the USB 2.0 high speed storage class applications such as Hard Disk, CD-ROM, CD-R / RW and DVD-ROM. ©2000-2002 Genesys Logic Inc.—All rights reserved.
