The MLX90121 13.56MHz RFID transceiver IC is aiming at target applications such as portable data terminals, access control readers, contact-less payment terminals and smart label printers. The chip consists of an analogue front end hooked up to a digital pre-processor which handles ASK, FSK and PSK demodulation and data encoding. The front-end circuitry may be used independently of the digital pre-processor when in direct mode. It conforms to ISO/IEC14443A/B and ISO/IEC15693 standards and provides support for non-ISO/IEC compliant applications. The device will be further upgraded later this year in order to accommodate the higher data rates of the ISO/IEC standards, as well as to fully support the Near Field Communication (NFC) protocol.
