1. Introduction
1.1 Description
AU9525 is a highly integrated single chip, is the second generation USB Smart Card
reader controller. Highly integration enables the lowest BOM cost of USB Smart Card
reader. The AU9525 supports multiple international standards including ISO7816 for
IC card standard, PC/SC 1.0 for windows smart card standard, Microsoft WHQL, EMV
for Europay MasterCard Visa standard and USB-IF CCID standard. And support
flexible Keyboard/LCM display interface. With our embedded enhanced 8051 MCU,
user can self control Keyboard/LCM display by AP. Manufacturers can easily create a
higher-security Smart Card reader by deploying Au9525. The application of AU9525
can be generally applied to Smart Card read/write terminal device, such as ATM, POS
terminal, Public telephone, E-Commerce, personal consumption on Internet, personal
certification, prepay system, loyalty system…etc.
