Features and Applications

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


  • Highly integrated analog circuitry for demodulating and decoding card response
  • Buffered output drivers enable antenna connection using the minimum of external
  • Proximity operating distance up to 100 mm
  • Supports the ISO/IEC 14443 A standard, parts 1 to 4
  • Supports MIFARE Classic protocol
  • Crypto1 and secure non-volatile internal key memory
  • Pin-compatible with the CLRC632, MFRC530, MFRC531 and the SLRC400
  • Parallel microprocessor interface with internal address latch and IRQ line
  • Flexible interrupt handling
  • Automatic detection of parallel microprocessor interface type
  • 64-byte send and receive FIFO buffer
  • Hard reset with low power function
  • Software triggered Power-down mode
  • Programmable timer
  • Unique serial number
  • User programmable start-up configuration
  • Bit-oriented and byte oriented framing
  • Independent power supply pins for analog, digital and transmitter modules
  • Internal oscillator buffer optimized for low phase jitter enables 13.56 MHz quartz
  • Clock frequency filtering
  • 3.3 V operation for transmitter in short range and proximity applications
