Product details
Overview
PN5110A0HN1/C2 from NXP Semiconductors is a 13.56 MHz NFC/RFID transceiver IC supporting ISO/IEC 14443A/Mifare, FeliCa, and NFCIP-1 protocols in Reader/Writer, Card Operation, and NFCIP-1 modes. It delivers up to 424 kbit/s bidirectional data transfer, integrates RF transmitter/receiver circuitry with TX1/TX2 outputs and RX input, and operates from a 2.5–3.6 V supply. It enables contactless reader designs for access control terminals and transit fare systems.
For engineers reviewing the PN5110A0HN1/C2 datasheet, PN5110A0HN1/C2 pinout, PN5110A0HN1/C2 application, or PN5110A0HN1/C2 equivalent, this page provides verified technical context on its triple-mode operation, HVQFN32 package constraints, SPI/I²C/UART host interface support, integrated CRC co-processor, and RF-level detection capability - all critical for NFC system integration and antenna matching.
Technical Context
The PN5110A0HN1/C2 implements a fully integrated analog front-end for 13.56 MHz contactless communication, featuring dual transmitter outputs (TX1/TX2), a single receiver input (RX), internal oscillator supporting 27.12 MHz crystal, and RF level detector for field presence sensing. Its digital baseband handles ISO/IEC 14443A framing, FeliCa preamble/sync insertion, and NFCIP-1 active/passive mode state management.
It supports three distinct operational states: Reader/Writer mode with Mifare Classic encryption and 424 kbit/s ASK-modulated transmission; Card Operation mode using load modulation (LOADMOD output) for emulating ISO14443A/FeliCa cards; and NFCIP-1 mode compliant with ECMA-340/ISO/IEC 18092, including automatic interface detection across SPI, I²C, UART, and (exclusively in HVQFN40) 8-bit parallel.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN5120A0HN/C2 | HVQFN40 package with 8-bit parallel interface support; identical RF/analog architecture and protocol stack. | Required when host MCU lacks SPI/I²C but offers parallel bus; larger footprint and higher pin count. | Select PN5120A0HN/C2 only if 8-bit parallel interface is mandatory; otherwise PN5110A0HN1/C2 offers smaller size and lower cost. |
| PN7150B0HN/C2 | Integrated firmware, NFC Forum-certified stack, I²C-only interface, and lower power consumption (typ. 15 mA active). | Designed for plug-and-play NFC controller use cases; lacks raw register-level access and multi-interface flexibility. | Choose PN7150B0HN/C2 for rapid certification-compliant deployment; retain PN5110A0HN1/C2 for full hardware control and custom protocol extensions. |
Compared with PN5120A0HN/C2, PN5110A0HN1/C2 saves board space and simplifies layout but excludes parallel interface; versus PN7150B0HN/C2, it offers deeper hardware configurability at the cost of increased firmware development effort and higher active current.

FAQ
What communication protocols does the PN5110A0HN1/C2 support?
The PN5110A0HN1/C2 supports ISO/IEC 14443A/Mifare (including Mifare Classic encryption), FeliCa, and NFCIP-1 (ECMA-340/ISO/IEC 18092) protocols across Reader/Writer, Card Operation, and NFCIP-1 modes. It handles all physical layer modulation, demodulation, framing, and CRC generation internally - no external protocol co-processor is needed for standard implementations of PN5110A0HN1/C2.
Does the PN5110A0HN1/C2 include an integrated oscillator?
Yes, the PN5110A0HN1/C2 includes an internal oscillator circuit compatible with a 27.12 MHz fundamental-mode quartz crystal connected between OSCIN and OSCOUT pins. This eliminates the need for an external clock source and ensures precise 13.56 MHz carrier generation essential for PN5110A0HN1/C2 compliance with NFC and RFID standards.
What is the maximum data transfer rate supported by the PN5110A0HN1/C2?
The PN5110A0HN1/C2 supports bidirectional data transfer rates up to 424 kbit/s in all operating modes - ISO/IEC 14443A/Mifare, FeliCa, and NFCIP-1 - using Modified Miller (14443A), Manchester (FeliCa), or BPSK (Mifare higher speeds) coding schemes. This rate is achievable without external buffering or acceleration circuitry in PN5110A0HN1/C2.
Can the PN5110A0HN1/C2 operate in card emulation mode?
Yes, the PN5110A0HN1/C2 supports Card Operation mode for both ISO/IEC 14443A/Mifare and FeliCa schemes. In this mode, it generates digital load-modulated signals via the LOADMOD pin and requires external circuitry to complete the analog modulation path. Full card functionality requires coordination with a secure core IC via the S2C interface - PN5110A0HN1/C2 handles only the physical layer.
What host interfaces are available on the PN5110A0HN1/C2?
The PN5110A0HN1/C2 supports SPI (up to 10 Mbit/s), I²C (Fast mode up to 400 kbit/s, High-Speed mode up to 3.4 Mbit/s), and UART (up to 1.2288 Mbit/s with RS232-like framing). The 8-bit parallel interface is not available on the HVQFN32 package of PN5110A0HN1/C2 - that feature is exclusive to the HVQFN40 variant (PN5110A0HN/C2).
