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.

MLX90132 Development kit
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} “
