• 读写模式支持 ISO/IEC 14443A/MIFARE

• 读写模式支持 SO/IEC 14443IB

• JIS X 6319-4 读写模式支持（等效于FeliCa 1 方案，请参阅章节 21.5）

• 相应于 ISO/IEC 18092 的被动发起方模式

• 读写模式支持 ISO/IEC 15693

• 读写模式支持 ICODE EPC UID/EPC OTP

• 读写模式支持 ISO/IEC 18000-3 mode 3/ EPC Class-1 HF

CLRC663 能够透过内建发射器直接驱动外置天线与 ISO/IEC 14443A 或 MIFARE 卡片进行通信，而无

需附加有源电路。数字模块负责全部的 ISO/IEC 14443A 组帧和错误检测功能（奇偶校验和 CRC 循環

冗餘校驗）-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 JIS X 6319-4 (comparable with FeliCa 1 (see

Section 30.5) scheme)

•　passive initiator mode according to ISO/IEC 18092

•　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
