Product Summary

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
The digital part handles ISO 14443A framing and
error detection (Parity & CRC). Additionally it
supports the fast CRYPTO 1 stream cipher to
authenticate MIFAREò Classic (MIFARE?
Standard, MIFARE? Light) products.
A comfortable parallel interface which can be
directly connected to any 8-bit μController gives
high flexibility for Reader / Terminal design.


The MF RC500 is tailored to fit the requirements
of various applications using contactless
communication based on ISO/IEC 14443A
standard where cost-effectiveness, small size,
high performance with a single voltage supply are
· Public transport terminals
· Handheld terminals
