AU9321 General Description


The AU9321 is a single chip integrated USB Compact Flash (CF) card reader controller.  It can be used as a removable storage disk in enormous data exchange applications between PC and PC or PC and various consumer electronic devices. 
 
The AU9321 can read of CF card's contents created by handheld consumer electronic devices such as digital camera, MP3 player, PDA and mobile phone. etc. It provides a faster and convenient way of data transfer scheme to meet the emerging need of a data exchange center between PC and various consumer devices. With AU9320, users' experience will be further enhanced by the Plug-and-Play nature built into latest operation systems such as Windows 2000/XP and Mac OS X.
 
Because of the multiple sectors transfer up to 4G bytes and the single chip integration, AU9321 will be the most powerful and cost efficient CF card reader controller solution in the market.

AU9321 Features

 Fully compliant with USB v1.1 specification and USB Device Class Definition for Mass Storage, Bulk-Transport v1.0
Fully compliant with Compact Flash (CF) v1.4 Specification.
Work with default driver from Windows ME, Windows 2000, Windows XP, Mac OS 9.1, and Mac OS X. Windows 98 is supported by vendor driver from Alcor.
