GL811S Product Overview
GENERAL DESCRIPTION
The GL811S 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 GL811S can support various kinds of ATA / ATAPI device. There are totally 4
endpoints in the GL811S 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 GL811S can support not only plug and
play but also Windows XP/ 2000/ ME default driver.
The GL811S uses 12MHz crystal and slew-rate controlled pads to reduce the EMI issue. With 48-pin LQFP
(7mmX7mm) package, the GL811S 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.
