MFRC530

The MFRC530 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, MFRC500, MFRC531 and SLRC400

 

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

The receiver module provides a robust and efficient demodulation/decoding circuitry implementation for compatible transponder signals. The digital module, manages the complete ISO/IEC 14443 A standard framing and error detection. In addition, it supports the fast Crypto1 security algorithm for authenticating the MIFARE products.

The internal transmitter module can directly drive an antenna designed for a proximity operating distance up to 100 mm without any additional active circuitry.

A parallel interface can be directly connected to any 8-bit microprocessor to ensure reader/terminal design flexibility. In addition, Serial Peripheral Interface (SPI) compatibility is supported.
