MFRC500

The MFRC500 is a member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz. This family of reader ICs provide:

• outstanding modulation and demodulation for passive contactless communication
• a wide range of methods and protocols
• pin compatibility with the CLRC632, MFRC530, MFRC531 and SLRC400

All protocol layers of the ISO/IEC 14443 A are supported.
