INTRODUCTION
Scope
The MF RC500 is member of a new family of highly integrated reader ICs for contactless communication on 13,56MHz. This new reader IC family utilises an outstanding modulation and demodulation concept completely integrated for all major kinds of passive contactless communication methods and protocols on 13,56MHz.
The MF RC500 supports all layers of ISO14443A.
The internal transmitter part is able to drive a proximity antenna (up to 100mm) directly without additional active circuitry.
The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals of ISO14443A compatible transponders.
