1. Introduction
1.1 Description
The AU6376 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 AU6376-GEL is maximized by implementing the latest and fastest card specification available form the industry. Especially, AU6376-GEL 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.
1.2 Features
Support USB V2.0 specification and USB Device Class Definition for Mass Storage, Bulk-Transport V1.0 Support CF/MD/SD/MMC/MS/MS_Pro/MS_Duo/xD/SMC compatible flash card Support SD1.1/SD2.0 Support MMC4.1. MMC4.2. Support CF4.0 DMA mode. Compliant to xD 1.2 spec. Hardware DMA engine integrated for performance enhancement. Work with default driver from Windows ME/2000/XP/Vista and Mac OS X; Windows 98/2000(SP1/SP2) and Mac OS 9 are supported by vendor driver from Alcor. Ping-pong FIFO implementation for concurrent bus operation Support multiple sectors transfer optimize performance Support slot-to-slot read/write operation Support Dynamic Icon Utility Support LED for bus operating indication Power switch integrated to reduce production BOM cost 30MHz 8051 CPU Built in 3.3V to 1.8V regulator Runs at 12MHz crystal Available in 100-pin LQFP package
