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.
