Designed for automotive applications, the Melexis MLX90132 is a 13.56MHz, fully integrated, multi-protocol RFID/NFC transceiver IC that supports ISO/IEC protocols 18092, 14443A and B, 15693 as well as 18000-3. It has been designed to handle sub-carrier frequencies from 106 to 848 kHz and baud rates up to 848kbit/s. The digital section of the MLX90132 handles the low protocol layers from API to physical layer using advanced bit and frame decoding functions.
The MLX90132 embeds tag emulation functionality for NFC support. The device offers 2 modes and 6 different states of operation in order to enable ultra low power consumption of the whole system. In hibernate state power consumption is less than 10uA, while in NFC target the device consumes 2.5mA.
The MLX90132’s 256 byte buffer can handle buffering an entire RFID frame. The SPI/UART communication ports interface with the majority of microcontrollers.
Major use cases for the MLX90132 are:
Car access and car start
Car interior setup according to different drivers, such as infotainment; seat position, heating and mirrors; telematics; engine/chassis setup and preference configuration.
User authentication—car rentals
Support to wireless communication—such as Wi-Fi and Bluetooth—with benefit of reduced setup time
The MLX90132 is packaged in a 5x5mm QFN package and rated for operation over -40° to +105°C. It is manufactured and qualified according to AEC-Q100 automotive standard. The device is available in sample quantities immediately.
