1 Introduction
The AS3990UHF reader development kit supports the EPC generation 2 standards. The aim
of the Demonstration kit is to show some of the features of the AS3990 UHF reader chip and
to allow the customers to start development of the application.
The system comprises of one board with two configurations: the UHF stand alone operation
with the help of the on board microcontroller.
For development purposes the MCU board can be disabled and the host system can directly
access the AS3990 using pin header. The operational RF part can be used to develop
customized software that will control the AS3990. A description of the interface can be found
in the chapter of technical description. This operation mode will allow to direct acces to the
IO pins with an external microcontroller and so speed up the design.
