1 Introduction
The AS3990UHF reader development kit supports the EPC generation 2 standards. The aim
of the development 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 software in the host system prior
to reader hardware design completion.
The system comprises of two boards: the UHF board and the MCU board including the LCD.
On the UHF board the main components are the AS3990 UHF chip, external RF power
amplifier, circulator, external VCO, and TCXO. On the MCU board the main components are
MSP430 micro controller, LCD display, and USB interface. The two boards are connected via
30 pin connector.
The demonstration board can both operate as stand-alone Reader as well as operate by graphic
user interface (GUI) when connected to a USB PC port. All mandatory commands and some
optional commands for the EPC generation2 standard are supported.
For development purposes the MCU board can be removed and the host system can directly
access the AS3990 using a 30 pin connector. 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.
1.1 Getting started
1.1.1 System assembly
Use a 50 Ohm coaxial cable to connect the SMA connector on the reader board with
the SMA connector on the patch antenna.
Use DC power supply or a stabilized laboratory power supply with current rating of at
least 600 mA at output voltage with a voltage setting of 8 Vdc for supply the reader
board. Use USB cable to connect PC and the reader board.
1.1.2 Stand-alone operation
When power is supplied to the board, Reader automatically starts stand-alone operation. In
this operation Reader continuously searches transponders in antenna field and inventories
them up to a maximum count of 8 pieces.
Basic data is displayed on LC-Display:
in the first line selected frequency, Tari selection, modulation selection and link
frequency are displayed
second line shows current number of transponders in the field and number of slots that
are used .
PC and EPC information of inventoried transponders in hexadecimal format are
displayed in the third and fourth line.
