1.0 Introduction
1.1 Description
The AU6375 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 AU6375 is maximized by implementing the latest and fastest card
specification available form the industry.
Especially, AU6375 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.
