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 protocols. 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 a stand-alone easy and
quick evaluation of the MLX90132. A Development mode
can also be selected to control the device through a set of
TCL script examples allowing the development of higher
layer applications.
