1 General description

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 and

CRC).

The CLRC663 supports MIFARE Classic with 1 kB memory, MIFARE Classic with 4 kB memory, MIFARE

Ultralight, MIFARE Ultralight C, MIFARE Plus and MIFARE DESFire products. The CLRC663 supports higher

transfer 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 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. The FeliCa receiver part provides the

demodulation and decoding circuitry for FeliCa coded signals. The CLRC663 handles the FeliCa framing and

error detection such as CRC. The CLRC663 supports FeliCa higher transfer speeds of up to 424 kbit/s in both

directions.

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 mode

3/ 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)

2 Features and benefits

? Includes NXP ISO/IEC14443-A and Innovatron ISO/IEC14443-B intellectual property licensing rights

? High performance multi-protocol NFC frontend for transfer speed up to 848 kbit/s

? Supports ISO/IEC 14443 type A, MIFARE Classic, ISO/IEC 14443 B and FeliCa reader modes

? P2P passive initiator mode in accordance with ISO/IEC 18092

? Supports ISO/IEC15693, ICODE EPC UID and ISO/IEC 18000-3 mode 3/ EPC Class-1 HF

? Supports MIFARE Classic product encryption by hardware in read/write mode

Allows reading cards based on MIFARE Ultralight, MIFARE Classic with 1 kB memory, MIFARE Classic with 4

kB memory, MIFARE DESFire EV1, MIFARE DESFire EV2 and MIFARE Plus ICs

? Low-Power Card Detection

? Compliance to EMV contactless protocol specification on RF level can be achieved

? Supported host interfaces:

– SPI up to 10 Mbit/s

– I2C-bus interfaces up to 400 kBd in Fast mode, up to 1000 kBd in Fast mode plus

– RS232 Serial UART up to 1228.8 kBd, with voltage levels dependent on pin voltage supply

? Separate I2C-bus interface for connection of a secure access module (SAM)

? FIFO buffer with size of 512 bytes for highest transaction performance

? Flexible and efficient power-saving modes including hard power down, standby and low-power card detection

? Cost saving by integrated PLL to derive system clock from 27.12 MHz RF quartz crystal

? 3.0 V to 5.5 V power supply (CLRC66301, CLRC66302)

2.5 V to 5.5 V power supply (CLRC66303)

? Up to 8 free programmable input/output pins

? Typical operating distance in read/write mode for communication to a ISO/IEC 14443 type A and MIFARE

Classic card up to 12 cm, depending on the antenna size and tuning

? Two package options are available for the CLRC66303:

1. HVQFN32: Package with wettable flanks easing the soldering process and quality control of soldered parts

2. VFBGA36: Smallest package with optimized pin configuration for simple PCB layout

? The version CLRC66303 offers a more flexible configuration for Low-Power Card detection compared to the

CLRC66301 and CLRC66302 with the new register LPCD_OPTIONS. In addition, the CLRC66303 offers new

additional settings for the Load Protocol which fit very well to smaller antennas. The CLRC66303 is therefore

the recommended version for new designs.
