Description
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
300milliwatts 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 to support NFC Peer to Peer passive
communication mode. 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 encoding/decoding
functions. It contains a digital demodulator based
on sub-carrier detection and a programmable
bit/symbol encoder/decoder. It also encodes and
decodes the start and stop bits, parity bits, extra
guard time (EGT), start and end of frame
(SOF/EOF) and CRC.
Its 528 byte buffer handles an entire RFID frame.
The SPI/UART communication ports guarantee
easy interface with the majority of
microcontrollers.
