1.0 Introduction
1.1 Description
The AU9350 is a single chip integrated USB SmartMediaCard (SMC) 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 appliances.
The AU9350 reads digital data saved on SmartMediaCard while users manipulating electronic
devices such as digital cameras, MP3 players, PDAs and mobile phones… etc. By the
AU9350, users can transfer information such as data, graphics, texts or digital images from
one electronic device to another quickly and easily. With AU9350, users’experience will be
further enhanced by the USB Plug-and-Play nature built into latest operation systems such as
Windows 2000/XP and Mac OS X.
By integrating of various analog components, the AU9350 is the most powerful and most
effective solution for smar mediacard reader.
1.2 Features
Fully compliant with USB v1.1 specification and USB Device Class Definition for
Mass Storage, Bulk-Transport v1.0
Fully compliant with SmartMediaCard (SMC) Standard 2000 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.
