CLRC66302HN,151

CLRC663, the high performance multi-protocol NFC frontend.

The CLRC663 multi-protocol NFC frontend IC supports the following operating modes

• Read/write mode supporting ISO/IEC 14443 type A and MIFARE Classic communication mode

• Read/write mode supporting ISO/IEC 14443B

• Read/write mode supporting JIS X 6319-4 (comparable with FeliCa)1• 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/ EPC Class-1 HF

The CLRC663’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443A and MIFARE Classic IC-based cards and transponders without additional active circuitry.

The digital module manages the complete ISO/IEC 14443A framing and error detection functionality (parity andCRC).

The CLRC663 supports MIFARE Classic with 1 kB memory, MIFARE Classic with 4 kB memory, MIFAREUltralight, MIFARE Ultralight C, MIFARE Plus and MIFARE DESFire products.

The CLRC663 supports highertransfer speeds of the MIFARE product family up to 848 kbit/s in both directions.The CLRC663 supports layer 2 and 3 of the ISO/IEC 14443B reader/writer communication scheme exceptanticollision. The anticollision needs to be implemented in the firmware of the host controller as well as in theupper layers.The CLRC663 is able to demodulate and decode FeliCa coded signals. The FeliCa receiver part provides thedemodulation and decoding circuitry for FeliCa coded signals.

The CLRC663 handles the FeliCa framing anderror detection such as CRC. The CLRC663 supports FeliCa higher transfer speeds of up to 424 kbit/s in bothdirections.The CLRC663 is supporting the P2P passive initiator mode in accordance with ISO/IEC 18092.

The CLRC663 supports the vicinity protocol according to ISO/IEC15693, EPC UID and ISO/IEC 18000-3 mode3/ EPC Class-1 HF.The following host interfaces are supported:

• Serial Peripheral Interface (SPI)

• Serial UART (similar to RS232 with voltage levels dependent on pin voltage supply)

• I2C-bus interface (two versions are implemented: I2C and I2CL)
