General Description
The MLX90132 is a 13.56MHz RFID/NFC transceiver IC developed by Melexis. The DVK90132 is an assembled printed circuit board simplifying the evaluation of the MLX90132 and allowing the development of specific applications like NFC reader for car access.
The DVK90132 embeds a minimum set of components around the MLX90132 IC to make it functional as an NFCIP-2 reader compliant with ISO/IEC144 43 (type A and type B up to 848kbps), ISO /IEC18092 (up to 42 4kbps) and ISO/IEC15693 interna tional protoc ols. The development kit DVK90132 also features on-PCB printed RFID antennas with optimized matching network for the maximum RFID performances.
The DVK90132 is connected to a microcontroller board based on a STM32F103 ARM CORTEX M3 from the company STMicroelectronics embeds the required firmware for stand-alone RFID communications for easy and quick evaluation. A Development mode can also be selected to control the MLX90132 through a set of TCL scripts allowing the development of higher layer applications.

1 DVK90132 global description

The development kit DVK90132 is composed of two boards connected together with specific PCB connections.
The first board embeds the MLX90132 NFC reader IC and the minimum required components to make it functional as an NFCIP-2 reader compliant with ISO/IEC14443 (type A and type B up to 848kbps), ISO/IEC18092 (up to 424kbps) and ISO/IEC15693 international protocols. Two on-PCB printed RFID antennas are availabl e and selected through 0ohm bridg e resistors. An optimized matching n etwork is also available for maximum RFID performances.
The second board form ing the DVK90132 is a microcontrol ler PCB based on a STM32F103 ARM CO RTEX M3 form the com pan y STMic roelec tronics RFID communications for eas y and quick evaluation . A Deve lopm ent m ode can als o be selecte d to contr ol th e MLX90132 through a s et of TCL scripts allowing the development of higher la yer applications. The board is featuring an LCD displaying information in stand-alone mode and also a on-PCB joystick use for user selection.

3 Software installation

The f ollowings paragra phs describe ho w to download and ins tall the TCL s oftware and how to instal l the USB driver.

3.1 STM32 USB driver

The USB drivers are autom atically installed and recognized b y the operating system when connected to the user computer, there is no need of specific driver installing.

3.2 TCL software

There are several p ossib ilities to int erf ace the D VK901 32 a nd sev eral s oftwar es a vailabl e to write T CL sc ripts . The following paragraphs propose a suite of software w hich can be downloaded and use d for free. The user has to agree with the respective software license.

3.2.1 TCL engine: ActiveTcl

The software can be downloaded on: http://www.activestate.com/activetcl/downloads Select the version corresponding to your computer OS and ins ta ll it . This software includes the TCL compiler.

3.2.2 TCL editor: Ezdit

The software can be downloaded on: http://code.google.com/p/ezdit/downloads/detail?name=ezdit-windows-
0.9.1.zip&can=2&q
This editor allows to edit and to execute TCL scripts. It can be used without installation. To link the editor to the TCL engine, named wish85, installed with ActiveTCL it is necessary to do the following:
- Select TOOLS and click run
- In the second row write the path to the executable tclsh85.exe and add the command {%F}. In our example “C:/Tcl/bin/tclsh85.exe {%F} “
