Product details
Overview
CLRC66302HN,151 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 HF modes. It integrates dual 13.56 MHz transmitters (TX1/TX2), 512-byte FIFO, hardware MIFARE Classic encryption, and operates from 3.0 V to 5.5 V. It enables contactless reader designs for access control terminals with up to 12 cm read range.
For engineers reviewing the CLRC66302HN,151 datasheet, CLRC66302HN,151 pinout, CLRC66302HN,151 application, or CLRC66302HN,151 equivalent, this page delivers verified technical context, exact package mapping (HVQFN32), confirmed host interface options (SPI/I²C/UART), real-world use value in low-power card detection, and validated alternative part selection guidance.
Technical Context
The CLRC66302HN,151 implements a dual-transmitter analog front-end with dedicated TX1 and TX2 outputs for optimized antenna coupling and RF field shaping. Its digital baseband handles full ISO/IEC 14443A framing, CRC/parity, and MIFARE Classic cryptographic acceleration - offloading layer-2 protocol handling from the host MCU.
It supports three independent host interfaces (SPI up to 10 Mbit/s, I²C Fast-mode Plus up to 1000 kBd, UART up to 1228.8 kBd) with configurable multifunction pins (IF0–IF3), plus a dedicated SAM I²C interface. Low-power card detection (LPCD) uses internal timers and analog threshold monitoring without host intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC frontend applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CLRC66303HNE | Wettable flanks HVQFN32; extended LPCD register (LPCD_OPTIONS); supports 2.5 V min supply | Better solder joint inspection; lower voltage operation enables direct connection to 2.5 V SoCs | Preferred for new designs requiring enhanced manufacturability or wider supply range |
| PN5180A0HN/C1 | Single-transmitter architecture; integrated 13.56 MHz oscillator; supports ISO14443A/B/FeliCa/15693 but no EPC HF mode | Limited to 10 cm max range; lacks dedicated SAM interface; smaller 40-pin HVQFN package | Suitable for cost-sensitive, space-constrained readers where EPC HF and SAM are not required |
Compared with CLRC66302HN,151, CLRC66303HNE offers improved production yield via wettable flanks and broader voltage flexibility, while PN5180A0HN/C1 trades protocol breadth and security features for reduced footprint and bill-of-materials cost - making it viable only when EPC HF, SAM integration, or maximum 12 cm range are non-critical.

FAQ
What host interfaces does CLRC66302HN,151 support?
CLRC66302HN,151 supports SPI (up to 10 Mbit/s), I²C-bus (Fast-mode Plus up to 1000 kBd), and Serial UART (up to 1228.8 kBd). Interface selection is configured via IFSEL0/IFSEL1 pins, and IF0–IF3 are multifunction pins assignable to any of these protocols. A separate I²C interface is provided for secure access module (SAM) connection.
Does CLRC66302HN,151 include hardware acceleration for MIFARE Classic?
Yes, CLRC66302HN,151 includes dedicated hardware for MIFARE Classic encryption and authentication, enabling full CRYPTO1 cipher execution without host MCU involvement. This reduces transaction latency and CPU load during read/write operations with MIFARE Classic 1 kB and 4 kB cards.
What is the operating temperature range for CLRC66302HN,151?
The CLRC66302HN,151 is rated for an operating ambient temperature range of −25 °C to +85 °C, as specified in Table 1 of the official datasheet. This range applies to industrial-grade deployment in access control panels, kiosks, and other commercial equipment with adequate PCB heat dissipation.
How does CLRC66302HN,151 implement low-power card detection (LPCD)?
CLRC66302HN,151 performs autonomous low-power card detection using internal analog comparators monitoring antenna signal amplitude, coupled with timer-controlled sampling. When a card enters the RF field, LPCD triggers the LPCDIRQ interrupt and wakes the device from standby - eliminating continuous host polling and extending battery life in portable readers.
What package type is used for CLRC66302HN,151?
CLRC66302HN,151 uses the HVQFN32 package: plastic thermal enhanced very thin quad flat package with 32 terminals + 1 central ground pad, body dimensions 5 × 5 × 0.85 mm, and moisture sensitivity level 1 (MSL1).
