Product details
Overview
CLRC66302HN,118 from NXP Semiconductors is a high-performance multi-protocol NFC frontend IC supporting ISO/IEC 14443A/B, FeliCa (JIS X 6319-4), ISO/IEC 15693, ISO/IEC 18092 P2P passive initiator, and EPC Class-1 HF modes. It delivers up to 848 kbit/s transfer speed in MIFARE Classic read/write mode, integrates a 512-byte FIFO buffer, and operates from 3.0 V to 5.5 V supply. It is used in secure access control terminals requiring robust contactless card detection at up to 12 cm range.
For engineers reviewing the CLRC66302HN,118 datasheet, CLRC66302HN,118 pinout, CLRC66302HN,118 application, or CLRC66302HN,118 equivalent, this page provides verified technical context, validated pin functions, real-world use scenarios, and confirmed alternative options for industrial and secure access designs.
Technical Context
The CLRC66302HN,118 implements dual transmitter outputs (TX1/TX2) and differential receiver inputs (RXP/RXN) for optimized 13.56 MHz RF front-end performance. Its analog interface handles full ASK modulation and subcarrier load modulation demodulation per ISO/IEC 14443-A/B and FeliCa standards, with hardware-accelerated CRC and parity handling for type A framing.
Digital functionality includes five independent timers (four configurable to 13.56 MHz or 212 kHz, one LFO-based wake-up timer), a dedicated SAM I²C interface, and host interface selection via IFSEL0/IFSEL1 pins for SPI, UART, or I²C-L operation. The device uses an internal PLL to derive system clocks from a 27.12 MHz crystal connected to XTAL1/XTAL2.

FAQ
What is the maximum operating distance supported by CLRC66302HN,118?
The CLRC66302HN,118 achieves a typical operating distance of up to 12 cm in ISO/IEC 14443 type A and MIFARE Classic read/write mode. This range depends on antenna size, tuning, and environmental factors such as nearby metal or shielding. The device's dual TX outputs and differential RX inputs enable robust field shaping and signal recovery critical for consistent long-range performance.
Does CLRC66302HN,118 support FeliCa communication?
Yes, CLRC66302HN,118 supports FeliCa (JIS X 6319-4) communication in read/write mode, including demodulation, decoding, framing, and CRC handling. It supports FeliCa transfer speeds up to 424 kbit/s in both directions and handles FeliCa-specific signal characteristics such as subcarrier modulation and pulse-position encoding.
Can CLRC66302HN,118 operate with a 2.5 V supply?
No, CLRC66302HN,118 requires a minimum supply voltage of 3.0 V and supports operation up to 5.5 V. For 2.5 V operation, the CLRC66303 variant (e.g., CLRC66303HNE) must be used, as it is explicitly rated for 2.5 V to 5.5 V supply - a key differentiator confirmed in the official datasheet's Quick Reference Data tables.
How does CLRC66302HN,118 handle MIFARE Classic encryption?
CLRC66302HN,118 includes on-chip hardware acceleration for MIFARE Classic authentication and data encryption using Crypto1. This allows secure read/write operations with MIFARE Classic 1 kB and 4 kB cards without burdening the host MCU, reducing transaction time and improving system responsiveness in access control and payment terminals.
What host interfaces are available on CLRC66302HN,118?
CLRC66302HN,118 supports SPI (up to 10 Mbit/s), I²C-bus (Fast-mode Plus, up to 1000 kBd), and Serial UART (RS-232 compatible, up to 1228.8 kBd). Interface selection is controlled via IFSEL0/IFSEL1 pins, and a dedicated I²C bus is provided for secure access module (SAM) connection - enabling simultaneous host and SAM communication.
