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.
