[原创] NXP CLRC663无接触读卡器解决方案

NXP公司的CLRC663是新一代高性能近距离非接触式读卡器,支持多种协议如MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight,MIFARE Ultralight C, MIFARE PLUS和MIFARE DESFire,数据速率高达848kbps,适用于银行,电子政务,交通,移动支付等众多基础设施应用.本文介绍了CLRC663主要特性和优势,框图,应用电路以及CLEV663无接触读卡器评估板主要特性,电路图和材料清单.

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.

The CLRC663 supports layer 2 and 3 of the ISO/IEC 14443B　reader/writercommunication scheme except anticollision. The anticollision needs to be implemented in the firmware of the host controller as well as in the upper layers.

The CLRC663 is able to demodulate and decode FeliCa coded signals.TheFeliCa receiver part provides the demodulation and decoding circuitry for FeliCa coded signals...
