Product details
Overview
PN5120A0HN1/C1,118 from NXP Semiconductors is a full NFC Forum-compliant frontend IC for 13.56 MHz contactless communication, supporting Reader/Writer, Card Operation, and NFCIP-1 modes. It integrates analog modulation/demodulation, CRC coprocessing, RF level detection, and supports ISO/IEC 14443A/MIFARE, ISO/IEC 14443B, FeliCa, and NFCIP-1 protocols - enabling secure transit ticketing, mobile payment terminals, and access control readers.
For engineers reviewing the PN5120A0HN1/C1,118 datasheet, PN5120A0HN1/C1,118 pinout, PN5120A0HN1/C1,118 application, or PN5120A0HN1/C1,118 equivalent, this device delivers verified 424 kbit/s transfer speeds in MIFARE, FeliCa, and NFCIP-1 modes; operates from 2.5 V to 3.6 V; features a 32-pin HVQFN32 package; and includes integrated transmitter drivers for direct antenna connection without external active circuitry.
Technical Context
The PN5120A0HN1/C1,118 implements a fully integrated analog front-end with dual TX outputs (TX1/TX2), single-ended RX input, internal 27.12 MHz oscillator support via OSCIN/OSCOUT, and programmable RF level and data mode detectors. Its digital baseband handles ISO/IEC 14443A framing, FeliCa sync/preamble insertion, and NFCIP-1 active/passive mode arbitration.
It supports four host interfaces - SPI (up to 10 Mbit/s), I²C (Fast/High-speed modes), UART (RS232-level), and 8-bit parallel (not available in HVQFN32) - with a 64-byte FIFO buffer, interrupt-driven operation via IRQ, and hardware reset/power-down control via NRSTPD. The S2C interface enables secure IC coupling for card emulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC frontend applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7150B0HN/C1 | Integrated NFC controller + secure element; supports Android Host Card Emulation (HCE); lower power (2.5 µA standby); no S2C interface. | Targeted at smartphone peripheral accessories and IoT devices requiring certified HCE stack, not standalone secure IC coupling. | Select PN7150B0HN/C1 when Android compatibility, built-in firmware, and ultra-low-power operation outweigh need for external secure IC integration. |
| CLRC66302HN/C1 | Same HVQFN32 footprint; adds ISO/IEC 15693 support; higher analog supply current (12 mA typ); no NFCIP-1 active mode. | Suitable for library RFID, asset tracking, and multi-standard industrial readers where VICC compatibility is required alongside MIFARE. | Choose CLRC66302HN/C1 when ISO/IEC 15693 tag reading and broader ISO/IEC 14443B interoperability are mandatory, and NFCIP-1 active mode is unnecessary. |
Compared with PN5120A0HN1/C1,118, PN7150B0HN/C1 offers simplified Android integration but lacks S2C and MIFARE Crypto-1 licensing, while CLRC66302HN/C1 extends tag protocol coverage at the cost of NFCIP-1 functionality and higher power draw - making PN5120A0HN1/C1,118 optimal for secure transit and payment systems requiring certified MIFARE/FeliCa/NFCIP-1 convergence.
