The FM17522 is a highly integrated Transceiver IC for Contactless communication at 13.56MHz.
The FM17522 Transceiver IC support Reader/Writer mode supporting ISO14443A protocal.
The FM17522’s internal transmitter part is able to drive a reader/writer antenna designed to communicate with ISO/IEC14443A cards and transponders without additional active circuitry. The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from ISO/IEC14443A compatible cards and transponders. The digital part handles the complete ISO/IEC 14443A framing and error detection. The FM17522 supports ISO/IEC14443A cards and transponders with transfer speeds from 106kbit/s to 424kbit/s in both directions.
