The MLX90131 is a 13.56MHz 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 robust and flexible receiver part of the MLX90131 enables designers of NFC/RFID reader device to fit their system requirements and to address the main communication standards with the same device.
The class-E amplifier allows the transmitter part to provide up to 250 miliwatts to a suitable antenna load. This delivered power is suitable for most short to mid range applications.
The MLX90131 embed tag emulation function for NFC capability. The tag and field detector will limit the power consumption in pure RFID reader configuration and in NFC mode.
The serial data interface of the MLX90131 is a compromise between flexibility for high speed data transfer and the pin-count required for the connection.
Several internal digital registers are used to configure the MLX90131 according to the standard of communication used. The digital section of the device contains ASK/FSK and PSK decoders based on sub-carrier detection, a programmable symbol encoder as well as a 15-bits FIFO.
