Product details
Overview
CLRC66301HN,557 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 CLRC66301HN,557 datasheet, CLRC66301HN,557 pinout, CLRC66301HN,557 application, or CLRC66301HN,557 equivalent, this page provides verified technical context, validated pin functions, confirmed protocol support boundaries, real-world operating distance data, and direct alternative part comparisons - all specific to the CLRC66301HN,557 variant with HVQFN32 package and 3.0–5.5 V operation.
Technical Context
The CLRC66301HN,557 implements dual transmitter outputs (TX1/TX2) for 13.56 MHz carrier generation and differential receiver inputs (RXP/RXN) with internal VMID reference, enabling high-sensitivity demodulation of ASK-modulated signals per ISO/IEC 14443A and load-modulated FeliCa signals. Its analog front-end includes integrated PLL for clock derivation from 27.12 MHz crystal, eliminating external oscillator components.
Digital functionality includes hardware-accelerated MIFARE Classic encryption, full ISO/IEC 14443A framing/CRC handling, and firmware-managed ISO/IEC 14443B anticollision. Host interface selection (SPI/I²C/UART) is controlled via IFSEL0/IFSEL1 pins, and interrupt-driven operation is supported through IRQ pin with configurable sources including RxIRQ, TxIRQ, LPCDIRQ, and timer underflow events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 5.5 V - supports direct integration into 3.3 V or 5 V industrial power rails without level-shifting. |
| Max Transfer Speed | 848 kbit/s - enables high-throughput MIFARE Classic transactions, reducing reader response latency in access control systems. |
| FIFO Buffer Size | 512 bytes - accommodates full APDU exchanges without host intervention, improving throughput in SPI/I²C host interfaces. |
| Operating Distance | Up to 12 cm - achievable with optimized antenna design, critical for hands-free access readers in door entry systems. |
| Power-Down Current | 8 nA typical - allows ultra-low-power wake-on-card-detection operation in battery-powered portable readers. |
| Host Interfaces | SPI (up to 10 Mbit/s), I²C (Fast-mode Plus, 1000 kBd), UART (RS-232 compatible, up to 1228.8 kBd) - offers flexible microcontroller connectivity options. |
| Package | HVQFN32, 5 × 5 × 0.85 mm, wettable flanks - supports automated optical inspection (AOI) and reliable reflow soldering in high-volume manufacturing. |
Pinout & Package
HVQFN32 package (SOT617-1), 5 mm × 5 mm body, 0.85 mm height, wettable flanks, MSL2 rating. Thermal pad (pin 33/VSS) serves as heatsink and ground reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX1 / TX2 | RF Transmitter Outputs | Deliver modulated 13.56 MHz carrier to antenna matching network; dual outputs enable balanced drive or redundancy. |
| RXP / RXN | Differential RF Receiver Inputs | Accept demodulated signal from antenna; differential topology rejects common-mode noise in noisy industrial environments. |
| VMID | Internal Receiver Reference | Provides stable mid-rail bias for receiver amplifiers - must be decoupled with 100 nF capacitor to PVDD. |
| IRQ | Interrupt Request Output | Active-low open-drain signal indicating RxIRQ, TxIRQ, LPCDIRQ, or timer events - enables low-latency host response. |
| IFSEL0 / IFSEL1 | Host Interface Selection | Configure interface mode (SPI/I²C/UART) at power-up - determines function of IF0–IF3 pins without firmware dependency. |
| PDOWN | Power-Down Control Input | Active-high signal entering hard power-down state with 8 nA current draw - essential for battery life in portable readers. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware MIFARE Classic Encryption | Accelerates authentication and data ciphering in read/write mode - eliminates MCU overhead and improves transaction security. |
| Low-Power Card Detection (LPCD) | Enables periodic wake-up scanning with <8 nA quiescent current - extends battery life in handheld NFC interrogators. |
| Dedicated SAM I²C Interface | Separate I²C bus (SCL/SDA) for secure access module connection - isolates cryptographic key storage from main host interface. |
| Integrated PLL Clock Generator | Derives system clock from 27.12 MHz crystal - removes need for external clock source and reduces BOM count. |
| Flexible Power Supply Domains | VDD (3.0–5.5 V), TVDD (3.0–5.0 V), PVDD (3.0–5.5 V), AVDD/DVDD (buffered) - enables independent noise isolation for analog/digital sections. |

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-flank HVQFN32 package; extended LPCD register set (LPCD_OPTIONS); supports 2.5–5.5 V supply. | Preferred for new designs requiring enhanced low-power card detection flexibility and broader voltage tolerance. | Select CLRC66303HNE when designing battery-powered devices needing deeper sleep states or wider input voltage range. |
| PN5180A0HN/C1 | Single-chip NFC controller with integrated MCU core; supports same protocols but adds firmware-executed anticollision and higher-level stack offload. | Reduces host MCU load in complex P2P or reader-to-reader use cases; lacks dedicated SAM interface. | Choose PN5180A0HN/C1 when host processing headroom is limited and firmware offload for ISO/IEC 14443B anticollision is required. |
Compared with CLRC66301HN,557, CLRC66303HNE offers superior low-power configurability and voltage flexibility but shares identical pinout and protocol engine; PN5180A0HN/C1 trades dedicated hardware crypto acceleration for embedded processing capability, making it suitable for stack-integrated rather than pure frontend roles.

FAQ
What is the maximum operating distance supported by CLRC66301HN,557?
The CLRC66301HN,557 achieves up to 12 cm read/write range with ISO/IEC 14443A and MIFARE Classic cards under optimal conditions: properly tuned 50 Ω antenna, 5 V supply, and minimal environmental interference. Range varies with antenna geometry, matching network Q-factor, and card type - actual deployment should validate against target transponders using the CLRC66301HN,557's built-in field strength monitoring registers.
Does CLRC66301HN,557 support ISO/IEC 14443B anticollision natively?
No, CLRC66301HN,557 does not implement ISO/IEC 14443B anticollision in hardware. The datasheet explicitly states that anticollision must be implemented in host firmware. CLRC66301HN,557 handles physical layer modulation/demodulation and framing only; upper-layer protocol management, including UID collision resolution, remains the responsibility of the connected microcontroller.
Can CLRC66301HN,557 interface directly with a secure access module (SAM)?
Yes, CLRC66301HN,557 includes a dedicated I²C interface (SCL/SDA pins) for connecting an external SAM. This isolated bus enables secure key storage and cryptographic operations independent of the main host interface - a requirement for EMV Level 1 certification and PCI PTS compliance in payment terminals using CLRC66301HN,557.
What host interface options are available on CLRC66301HN,557?
CLRC66301HN,557 supports SPI (up to 10 Mbit/s), I²C (Fast-mode Plus, 1000 kBd), and UART (RS-232 compatible, up to 1228.8 kBd). Interface selection is determined at power-up via IFSEL0/IFSEL1 pins, and multifunction pins IF0–IF3 adapt dynamically - allowing CLRC66301HN,557 to integrate with diverse host MCUs without hardware redesign.
Is CLRC66301HN,557 pin-compatible with CLRC66303HNE?
Yes, CLRC66301HN,557 and CLRC66303HNE share identical HVQFN32 pinout, mechanical dimensions, and electrical pin functions. Both use SOT617-1 package with wettable flanks and 32-terminal layout. However, CLRC66303HNE introduces new register bits (e.g., LPCD_OPTIONS) and supports 2.5 V minimum supply - firmware must verify register map compatibility before drop-in replacement.
