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 conforms to ISO/IEC14443 (type A and

type B up to 848kbps), ISO/IEC18092 (up to 424kbps)

and

ISO/IEC15693

international

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 a stand-alone easy

and

quick

evaluation

Development mode can also be selected to control the

device through a set of TCL script examples allowing

the development of higher layer applications.

Figure 4: Ezdit TCL editor configuration 4.2.3. DVK90132 DLL This DLL is used to link the DVK90132 with the TCL scripts. After having downloaded it from Melexis SoftDist (directory MLX90132/MLX90132_Software) it has to be placed at the root of the D:/ or C:/ drive.
Page 10: Getting Started With The Dvk90132
The DVK90132 allows very quick and easy evaluation of the MLX90132 NFC/RFID reader IC. By simply connecting the USB port to the user computer, the DVK90132 is supplied and Start-up menu appears. Then the user simply has to select the mode by moving left/right the Joystick on the board (a blue square shows the mode currently selected) and press on it.
