2. Application Block Diagram
Following application diagram demonstrates a typical card reader using the AU6336
chip. By connecting the card reader to a desktop or notebook PC through USB bus,
the AU6336 becomes a bus-powered, high speed USB card reader, which can be
used as a bridge for data transfer between Desktop PC and Notebook PC.
