CLRC663

Contactless reader IC

8.3 Contactless interface unit

The contactless interface unit of the CLRC663 supports the following read/write operating

modes:

• ISO/IEC14443A/MIFARE

• ISO/IEC14443B

• FeliCA

• ISO/IEC15693/ICODE

• ICODE EPC UID

• ISO/IEC 18000-3 mode 3/ EPC Class-1 HF

A typical system using the CLRC663 is using a microcontroller to implement the higher

levels of the contactless communication protocol and a power supply (battery or external

supply).

8.3.1 ISO/IEC14443A/MIFARE functionality

The physical level of the communication is shown in Figure 5.

The physical parameters are described in Table 5.
