Melexis公司的MLX90132是13.56MHz全集成的多协议NFC/RFID收发器,可处理亚载波频率106kHz到848kHz,波特速率高达848kbps.双路驱动器架构把外接元件数降到最少,能向合适的天线负载提供高达70mW RF功率,和ISO/IEC 18092 (NFC), ISO/IEC 14443 A1与B2, ISO/IEC 15693以及ISO/IEC 18000-3 模式1兼容.主要用在汽车接入和起动, 汽车发动机防盗,汽车诊断和汽车租赁.本文介绍了MLX90132主要特性和优势, 简化方框图, 典型应用电路, 外接天线网络和天线电路框图和并联接收的天线电路框图.

The MLX90132 is a 13.56MHz, fully integrated, multi-protocol RFID/NFC transceiver IC. It has been designed to handle sub-carrier frequencies from 106 to 848 kHz and baud rates up to 848kbit/s.

The dual driver architecture of the MLX90132 requires minimal external support components and allows the transmitter to provide up to 70 milliwatts RF power to an appropriate antenna load. This delivered power is suitable for most short to mid range applications.

The MLX90132 embeds tag emulation functionality for NFC support. Enhanced tag and field detection capabilities provide significant power consumption reduction in RFID reader configuration and in NFC mode.

The digital section of the MLX90132 handles the low protocol layers from API to physical layer using advanced bit and frame decoding functions.
