1. Introduction
1.1 Description
The AU6475 is a single chip integrated USB 2.0 multimedia card reader controller that
enables PC/DVD/Printer to read/write various type of flash media cards. Flash media
cards such as CF, SMC, XD, SD, MMC, Memory Stick are widely used in digital
camera, cell phone, PDA and MP3 player to store digital photos and compressed
music.
Performance of AU6475 is maximized by implementing the latest and fastest card
specification available form the industry.
Especially, AU6475 is designed with the high performance characteristic in flash card
I/O speed. Users can easy and fast transfer the digital content among the different
flash card.
