The CLRC663 is a highly integrated transceiver IC for contactless communication at 13.56 MHz. This transceiver IC utilizes an outstanding modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz.
The CLRC663 transceiver ICs support the following operating modes
• read/write mode supporting ISO/IEC 14443A/MIFARE
• read/write mode supporting ISO/IEC 14443B
• read/write mode supporting FeliCa scheme
• passive initiator mode according to NFCIP-1
• read/write mode supporting ISO/IEC 15693
• read/write mode supporting ICODE EPC UID/ EPC OTP
• read/write mode supporting ISO/IEC 18000-3 Mode 3
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 receiver module provides a robust and efficient implementation for demodulating and decoding signals from ISO 14443A/MIFARE compatible cards and transponders. The digital module manages the complete ISO 14443A framing and error detection functionality (parity and CRC).
The CLRC663 supports MIFARE 1K, MIFARE 4K, MIFARE Ultralight, MIFARE Ultralight C, MIFARE PLUS and MIFARE DESFire products. The CLRC663 supports contactless communication and uses the MIFARE higher transfer speeds of up to 848 kbit/s in both directions.
The CLRC663 supports all layers of the ISO/IEC 14443B reader/writer communicatio...
