MLX90132 13.56MHz RFID / NFC Transceiver Features and Benefits Application Examples Conforms with ISO/IEC 18092 (NFC) NFC enabled car for access and start Conforms with ISO/IEC 14443A and B, Combo NFC and Wireless Power Charging Conforms with ISO/IEC 15693 solutions Conforms with ISO/IEC 18000-3 mode 1 NFC applications in Industrial area (e.g. White High speed communication (up to 848kbit/s) goods, security ) Standard SPI/UART interfaces Built-in Field and TAG detectors Ordering Information Part Code Temperature Code Package Code Option Code Packing Form Code MLX90132 R (-40C to 105C) LQ (Lead free QFN 5x5 32 leads) AEA-000 RE MLX90132 R (-40C to 105C) LQ (Lead free QFN 5x5 32 leads) AEA-000 TU MLX90132 S (-20C to 85C) LQ (Lead free QFN 5x5 32 leads) AEA-000 RE MLX90132 S (-20C to 85C) LQ (Lead free QFN 5x5 32 leads) AEA-000 TU The dual driver architecture of the MLX90132 Functional Diagram requires minimal external support components and allows the transmitter to provide up to 300milliwatts RF power to an appropriate antenna MLX90132 load. This delivered power is suitable for most short to mid-range applications. RX1 TX1 The MLX90132 embeds tag emulation microcontroller TX2 SPI/UART Analog Digital functionality to support NFC Peer to Peer passive RX2 section section communication mode. Enhanced tag and field detection capabilities provide significant power consumption reduction in RFID reader configuration and in NFC mode. Figure 1: MLX90132 functional diagram The digital section of the MLX90132 handles the low protocol layers from API to physical layer Description using advanced bit and frame encoding/decoding functions. It contains a digital demodulator based on sub-carrier detection and a programmable The MLX90132 is a 13.56MHz, fully integrated, bit/symbol encoder/decoder. It also encodes and multi-protocol RFID/NFC transceiver IC. It has decodes the start and stop bits, parity bits, extra been designed to handle sub-carrier frequencies guard time (EGT), start and end of frame from 106 to 848 kHz and baud rates up to (SOF/EOF) and CRC. 848kbit/s. Its 528 byte buffer handles an entire RFID frame. The SPI/UART communication ports guarantee easy interface with the majority of microcontrollers. 3901090132 Page 1 of 44 Jan-2014 Rev. 009 MLX90132 13.56MHz RFID / NFC Transceiver Table of Contents 1
