Product details
Overview
PN5120A0HN/C1,518 from NXP Semiconductors is a full NFC Forum-compliant NFC frontend IC operating at 13.56 MHz, supporting Reader/Writer, Card Operation, and NFCIP-1 modes with transfer speeds up to 424 kbit/s. It integrates analog modulation/demodulation, CRC coprocessing, and RF level detection for ISO/IEC 14443A/MIFARE, ISO/IEC 14443B, and FeliCa protocols. Used in secure access terminals, transit ticketing readers, and industrial asset tag readers.
For engineers reviewing the PN5120A0HN/C1,518 datasheet, PN5120A0HN/C1,518 pinout, PN5120A0HN/C1,518 application, or PN5120A0HN/C1,518 equivalent, this page delivers verified technical context, validated HVQFN40 package mapping, confirmed 40-pin terminal roles, real-world operating distance data (up to 100 mm in card mode), and two documented alternative parts with functional and interface-level differences.
Technical Context
The PN5120A0HN/C1,518 implements a fully integrated analog front-end with buffered TX1/TX2 outputs capable of driving tuned antennas without external active circuitry in ISO/IEC 14443A/MIFARE Reader/Writer mode. Its digital baseband handles complete ISO/IEC 14443A framing, parity, and CRC16 generation/check, plus FeliCa and NFCIP-1 protocol framing with MSB-first CRC calculation.
It supports four host interfaces-SPI (up to 10 Mbit/s), I²C (Fast/High-speed modes), UART (RS232-level, up to 1228.8 kBd), and 8-bit parallel-with IRQ-driven interrupt control and a 64-byte FIFO buffer. The internal oscillator accepts 27.12 MHz crystal input via OSCIN/OSCOUT, and power domains include separate VDDA (2.5–3.6 V), VDDD, PVDD, TVDD, and SVDD rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz carrier frequency for all supported protocols - enables interoperability with global NFC infrastructure. |
| Max Data Rate | 424 kbit/s in ISO/IEC 14443A, FeliCa, and NFCIP-1 modes - supports high-throughput contactless transactions. |
| Supply Voltage Range | 2.5 V to 3.6 V on VDDA/VDDD - compatible with standard 3.3 V embedded systems without level-shifting. |
| Power-Down Current | ≤10 µA in soft power-down with RF level detector active - enables ultra-low-power standby in battery-powered devices. |
| Operating Temperature | −30 °C to +85 °C - qualified for industrial and consumer environments, excluding automotive-grade variants. |
| FIFO Depth | 64-byte send/receive buffer - reduces host CPU overhead during burst data transfers in reader or peer-to-peer mode. |
| Host Interfaces | SPI, I²C, UART, and 8-bit parallel - provides flexible integration with microcontrollers, SoCs, and legacy controllers. |
Pinout & Package
PN5120A0HN/C1,518 is housed in an HVQFN40 (SOT618-1) package: plastic thermal enhanced very thin quad flat package, no leads, 40 terminals, body size 6 × 6 × 0.85 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX1 / TX2 | RF Transmitter Outputs | Deliver modulated 13.56 MHz carrier to antenna; require external matching network for 40 Ω impedance. |
| RX | RF Receiver Input | Accepts load-modulated signals from cards/targets; internally amplified and demodulated. |
| IRQ | Interrupt Request Output | Active-low signal indicating completed command, FIFO status, or error condition - enables event-driven host operation. |
| NCS / NRD / NWR / ALE | Parallel Interface Control | Enable 8-bit parallel host interface (only available in HVQFN40); support address/data latching and strobed read/write. |
| D0–D7 | Bidirectional Data Bus | Transfer register data and FIFO contents; repurposable as I²C address pins or test I/Os in serial interface configurations. |
| OSCIN / OSCOUT | Crystal Oscillator Interface | Supports 27.12 MHz quartz crystal or external clock source - eliminates need for separate oscillator IC. |
| NRSTPD | Reset & Power-Down Input | Hard reset and power-down control: LOW disables oscillator, disconnects I/Os, and cuts internal current sinks. |
| TVDD / TVSS | Transmitter Power Domain | Dedicated supply for TX1/TX2 output stage - isolates RF power noise from digital/analog domains. |
Key Features
| Feature | Design Value |

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 firmware, single-wire host interface (SWP), no parallel interface; lower power (2.2 V–3.6 V). | Targeted for mobile accessories and wearables requiring compact BOM and simplified host integration. | Select when firmware offload and SWP compatibility outweigh need for parallel interface or 424 kbit/s FeliCa support. |
| CLRC66302HN/C1 | Enhanced security features (AES, DES), extended temperature range (−40 °C to +105 °C), same HVQFN40 package. | Designed for automotive and high-reliability industrial use cases requiring cryptographic acceleration and AEC-Q100 compliance. | Select when AES-128 encryption, extended temp range, or automotive qualification are mandatory design requirements. |
Compared with PN5120A0HN/C1,518, PN7150B0HN/C1 reduces host software complexity via embedded stack but sacrifices parallel interface and FeliCa speed; CLRC66302HN/C1 adds cryptographic engines and extended temperature rating at higher cost and power.

FAQ
What communication protocols does the PN5120A0HN/C1,518 support?
The PN5120A0HN/C1,518 supports ISO/IEC 14443A/MIFARE (including MIFARE Classic Crypto1), ISO/IEC 14443B, FeliCa, and NFCIP-1 protocols. It operates in Reader/Writer, Card Operation, and NFCIP-1 modes with transfer speeds up to 424 kbit/s. All protocol framing, CRC, and parity handling are performed in hardware, reducing host processing load for the PN5120A0HN/C1,518.
Does PN5120A0HN/C1,518 include an integrated oscillator?
Yes, the PN5120A0HN/C1,518 includes an internal oscillator circuit that accepts a 27.12 MHz quartz crystal connected between OSCIN and OSCOUT pins. This eliminates the need for an external oscillator IC and ensures precise timing alignment for 13.56 MHz carrier generation in the PN5120A0HN/C1,518.
What is the maximum operating distance achievable with PN5120A0HN/C1,518?
The PN5120A0HN/C1,518 achieves up to 50 mm in Reader/Writer mode and up to 100 mm in ISO/IEC 14443A/MIFARE or FeliCa Card Operation mode - both dependent on antenna size, tuning, and external field strength. These values are typical under optimized conditions with a 40 Ω matched antenna, as specified in the PN5120A0HN/C1,518 datasheet.
Which host interfaces are available on PN5120A0HN/C1,518?
The PN5120A0HN/C1,518 supports SPI (up to 10 Mbit/s), I²C (Fast/High-speed modes), UART (RS232-level, up to 1228.8 kBd), and 8-bit parallel interfaces. The 8-bit parallel interface is exclusive to the HVQFN40 package variant and requires NCS, NRD, NWR, and ALE control signals - a key differentiator of the PN5120A0HN/C1,518 over smaller-footprint versions.
Is PN5120A0HN/C1,518 pin-compatible with other PN512 variants?
No - PN5120A0HN/C1,518 (HVQFN40) is not pin-compatible with HVQFN32 or TFBGA64 variants due to differing pin counts and layouts. While functional register sets are consistent across the PN512 family, PCB layout must be redesigned when migrating between packages. The PN5120A0HN/C1,518 specifically requires 40-terminal routing and supports the full 8-bit parallel interface unavailable in 32-pin versions.
