1. General Description
The GL813 is a high performance, low cost USB2.0 CompactFlash-single card
reader controller. With the integration of GenesysLogic own design USB 2.0 high
speed UTMI transceiver, the GL813 has made a conspicuous improvement with
full speed USB 1.1 card readers on data transfer rate between PC host and flash
memory card.
There are totally 4 endpoints in GL813 controller, Control, Bulk In, Bulk Out, and
Interrupt. Complies with USB 480Mbps specification ver. 2.0 and USB Storage
Class specification ver. 1.0. (Bulk only protocol), the GL813 can support not only
plug and play but also Windows ME/ 2000/ XP default driver. For the EMI
consideration, the GL813 uses 12MHZ crystal and slew-rate controlled pads to
reduce the EMI issue.
The GL813 is 48-pin LQFP package (9mmX9mm) to make the best cost
competitive for the high speed single flash card reader design and applications.
Also we provide 100-pin LQFP package (14mmX14mm) with external ROM/ Flash
for design flexibility.
