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.
