Features & Applications

The CLRC66301HN,551 is a highly integrated transceiver IC for contactless communication at 13.56 MHz. It is available in HVQFN32 Package.

The CLRC663’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443A/MIFARE cards and transponders without additional active circuitry. The digital module manages the complete ISO/IEC 14443A framing and error detection functionality (parity and CRC).

The CLRC663 supports MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight,MIFARE Ultralight C, MIFARE PLUS and MIFARE DESFire products. The CLRC663 supports MIFARE higher transfer speeds of up to 848 kbit/s in both directions.

Features and Benefits:

  • High RF output power frontend IC for transfer speed up to 848 kbit/s
  • Supports ISO/IEC 14443 A/MIFARE, ISO/IEC 14443 B and FeliCa
  • P2P passive initiator mode in accordance with ISO/IEC 18092
  • Supports ISO/IEC15693, ICODE EPC UID and ISO/IEC 18000-3 mode 3/ EPC Class-1 HF
  • Supports MIFARE Classic encryption in read/write mode
  • Low-Power Card Detection
  • Compliance to “EMV contactless protocol specification V2.0.1” on RF level can be achieved
  • Antenna connection with minimum number of external components
  • Supported host interfaces:
    • SPI up to 10 Mbit/s
    • I²C-bus interfaces up to 400 kBd in Fast mode, up to 1000 kBd in Fast mode plus
    • RS232 Serial UART up to 1228.8 kBd, with voltage levels dependent on pin voltage supply
  • Separate I²C-bus interface for connection of a secure access module (SAM)
  • FIFO buffer with size of 512 byte for highest transaction performance
  • Flexible and efficient power saving modes including hard power down, standby and low-power card detection
  • Cost saving by integrated PLL to derive system CPU clock from 27.12 MHz RF quartz crystal
  • 3.3 V to 5 V power supply
  • Up to 8 free programmable input/output pins
  • Typical operating distance in read/write mode for communication to a ISO/IEC 14443A/MIFARE Card up to 12 cm, depending on the antenna size and tuning
