Product details
Overview
PN5120A0HN1/C2 from NXP Semiconductors is a full NFC Forum-compliant 13.56 MHz NFC frontend IC supporting Reader/Writer, Card Operation, and NFCIP-1 modes. It integrates analog modulation/demodulation, CRC coprocessor, 64-byte FIFO, and supports ISO/IEC 14443A/MIFARE, ISO/IEC 14443B, FeliCa, and NFCIP-1 protocols up to 424 kbit/s - deployed in secure access terminals and contactless payment readers.
For engineers reviewing the PN5120A0HN1/C2 datasheet, PN5120A0HN1/C2 pinout, PN5120A0HN1/C2 application, or PN5120A0HN1/C2 equivalent, key selection considerations include its HVQFN32 package, 2.5–3.6 V supply range, support for SPI/I²C/UART host interfaces, integrated RF level detector, and compatibility with MIFARE Classic encryption in Reader mode.
Technical Context
The PN5120A0HN1/C2 implements a fully integrated analog front-end for 13.56 MHz contactless communication, with independent transmitter (TX1/TX2) and receiver (RX) paths, internal oscillator for 27.12 MHz crystal, and digital baseband handling framing, parity, and CRC per ISO/IEC 14443-3 and FeliCa standards. Its S2C interface enables secure IC coupling for card emulation.
It operates across four distinct modes: ISO/IEC 14443A/MIFARE Reader/Writer (106/212/424 kbit/s), ISO/IEC 14443B Reader/Writer, FeliCa Reader/Writer (212/424 kbit/s), and NFCIP-1 (106/212/424 kbit/s, active/passive). Each mode uses dedicated demodulation logic, data mode detection, and protocol-specific UART control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz carrier with internal 27.12 MHz crystal oscillator support - enables precise RF timing without external clock source. |
| Supply Voltage Range | 2.5 V to 3.6 V (VDDA/VDDD) - compatible with standard 3.3 V embedded systems and allows direct integration with low-voltage microcontrollers. |
| Max Data Rate | 424 kbit/s in ISO/IEC 14443A, FeliCa, and NFCIP-1 modes - supports high-throughput transaction processing in transit fare and secure ID applications. |
| FIFO Depth | 64-byte bidirectional buffer - reduces host CPU interrupt load and enables burst transfers over SPI/I²C without data loss. |
| Receiver Sensitivity | Robust demodulation for ISO/IEC 14443A/MIFARE, FeliCa, and NFCIP-1 signals - achieves typical 50 mm read range with tuned antenna and 100 mm card emulation range. |
| Power-Down Current | <5 µA hard power-down (NRSTPD = LOW) - enables ultra-low-power standby in battery-powered handheld readers and wearables. |
| Host Interfaces | SPI (up to 10 Mbit/s), I²C (Fast/High-speed modes), UART (RS232-level, up to 1228.8 kBd) - provides flexible connectivity to diverse host controllers without level-shifting. |
Pinout & Package
HVQFN32 package (5 × 5 × 0.85 mm, SOT617-1), thermally enhanced, leadless, with exposed thermal pad - optimized for compact PCB layouts and efficient RF thermal management in space-constrained readers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX1, TX2 | RF Transmitter Outputs | Drive 13.56 MHz modulated carrier directly to antenna matching network - eliminates need for external PA in most reader designs. |
| RX | RF Receiver Input | Accepts load-modulated signal from cards/transponders - internally conditioned for high-SNR demodulation of ASK/Manchester/BPSK schemes. |
| IRQ | Interrupt Request Output | Active-low signal indicating frame completion, error, or FIFO status - enables event-driven host firmware with minimal polling overhead. |
| N_RSTPD | Reset & Power-Down Control | Asynchronous active-low input that disables oscillator, disconnects I/Os, and cuts internal current sinks - ensures deterministic low-power entry/exit. |
| OSCIN / OSCOUT | Crystal Oscillator Interface | Supports 27.12 MHz fundamental-mode quartz crystal - provides stable, low-jitter RF clock without external oscillator component. |
| VMID | Internal Reference Voltage | Delivers stable mid-supply reference for analog circuitry - improves ADC/DAC linearity and RF detector accuracy across voltage/temperature. |
| D1–D7, A0, A1 | Parallel Data/Address (I/O) | Configurable as I²C address pins or test I/Os - no 8-bit parallel interface enabled on HVQFN32 variant per datasheet Table 3 remark. |

It handles physical layer modulation/demodulation and baseband framing for all modes, with MIFARE Classic Crypto-1 licensing embedded. The PN5120A0HN1/C2 requires an external host controller to manage higher-layer protocol stacks.
Does the PN5120A0HN1/C2 include an integrated crystal oscillator?
Yes, the PN5120A0HN1/C2 includes an internal oscillator circuit supporting a 27.12 MHz fundamental-mode quartz crystal connected via OSCIN/OSCOUT pins. This eliminates the need for an external clock generator and ensures precise 13.56 MHz carrier synthesis. The oscillator is disabled during hard power-down (NRSTPD = LOW) to minimize leakage current.
What is the maximum operating temperature range for the PN5120A0HN1/C2?
The PN5120A0HN1/C2 is rated for ambient temperatures from −30 °C to +85 °C, as specified in the official NXP datasheet Rev. 5.2. This range applies to the standard version (PN5120A0HN1/C2); the industrial-grade PN512AA0HN1/C2 variant extends to −40 °C to +90 °C but is a separate orderable part.
Can the PN5120A0HN1/C2 operate in card emulation mode?
Yes, the PN5120A0HN1/C2 supports Card Operation mode for both ISO/IEC 14443A/MIFARE and FeliCa schemes. In this mode, it generates digital load-modulated signals and interfaces with a secure IC via the S2C interface to enable full card emulation functionality - essential for secure element integration in mobile wallets and identity tokens.
What host interfaces are available on the PN5120A0HN1/C2 HVQFN32 package?
The PN5120A0HN1/C2 in HVQFN32 supports SPI (up to 10 Mbit/s), I²C (Fast/High-speed modes), and UART (RS232-level, up to 1228.8 kBd). The 8-bit parallel interface is explicitly unavailable on this package variant per datasheet Table 3 remark - only HVQFN40 and TFBGA64 packages support parallel mode.
