Product details
Overview
PN512AA0HN1/C2 from NXP Semiconductors is a fully NFC Forum-compliant, AEC-Q100 Grade 3 qualified NFC frontend IC for 13.56 MHz contactless communication. It operates in four modes - ISO/IEC 14443A/MIFARE/FeliCa Reader/Writer, ISO/IEC 14443B Reader/Writer, Card Operation, and NFCIP-1 - with up to 424 kbit/s transfer speed and supports MIFARE Classic encryption. It drives antennas directly without external active circuitry in Reader/Writer mode and integrates RF level detection, data mode detection, and CRC coprocessing.
For engineers reviewing the PN512AA0HN1/C2 datasheet, PN512AA0HN1/C2 pinout, PN512AA0HN1/C2 application, or PN512AA0HN1/C2 equivalent, key selection considerations include its industrial-grade temperature range (−40 °C to +90 °C), HVQFN32 package compatibility with SPI/I²C/UART host interfaces, integrated analog demodulation for ISO/IEC 14443A/B/FeliCa/NFCIP-1, and S2C interface support for secure IC coupling.
Technical Context
The PN512AA0HN1/C2 implements a complete analog front-end for 13.56 MHz NFC with integrated transmitter (TX1/TX2), receiver (RX), RF level detector, and data mode detector. Its digital baseband handles full ISO/IEC 14443A framing, parity, and CRC16; FeliCa framing with automatic preamble/sync insertion; and NFCIP-1 framing per ECMA-340/ISO/IEC 18092.
It features a 64-byte FIFO buffer, programmable timer, hard/soft power-down modes, internal oscillator for 27.12 MHz crystal, and flexible interrupt control. Host connectivity includes SPI (up to 10 Mbit/s), I²C (Fast/High-speed modes), UART (RS232-level), and configurable GPIOs - though the 8-bit parallel interface is excluded in the HVQFN32 variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz carrier - enables interoperability with ISO/IEC 14443A/B, FeliCa, and NFCIP-1 standards. |
| Max Data Rate | 424 kbit/s - supports high-speed NFCIP-1 and FeliCa Higher transfer modes for fast transaction throughput. |
| Supply Voltage Range | 2.5 V to 3.6 V (VDDA/VDDD) - ensures compatibility with common 3.3 V embedded systems and low-power designs. |
| Operating Temperature | −40 °C to +90 °C - AEC-Q100 Grade 3 qualification enables use in automotive infotainment, telematics, and industrial HMI applications. |
| FIFO Depth | 64 bytes - buffers bidirectional data for efficient host interface handling without frequent polling or interrupts. |
| Power-Down Current | ≤15 µA (hard), ≤30 µA (soft) - minimizes standby power in battery-powered NFC readers and portable terminals. |
| Host Interfaces | SPI, I²C, UART - eliminates need for protocol translation logic and simplifies integration with microcontrollers and SoCs. |
Pinout & Package
HVQFN32 package (SOT617-1), 5 mm × 5 mm × 0.85 mm body, thermally enhanced, no leads. Exposed thermal pad on underside for PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1 | Address Input | Define register address mapping for parallel-style access; used for I²C address configuration when I²C interface is selected. |
| D1–D7 | Bi-directional Data Bus | Shared I/O lines supporting test signals, I²C address bits, or serial interface auxiliary functions - not used for 8-bit parallel mode in HVQFN32. |
| IRQ | Interrupt Output | Active-low signal indicating completion of command execution, FIFO status, or error condition - enables event-driven host firmware. |
| NRSTPD | Reset & Power-Down Control | Low-active input that disables internal current sinks, inhibits oscillator, and isolates I/O pads - enables ultra-low-power shutdown. |
| RX | Receiver Input | Single-ended analog input for demodulated card response signals - connects directly to antenna matching network output. |
| TX1, TX2 | Transmitter Outputs | Differential 13.56 MHz carrier outputs - drive antenna coil directly with complementary driver configuration (40 Ω matched load). |
| OSCIN / OSCOUT | Crystal Oscillator Interface | Supports 27.12 MHz fundamental-mode quartz crystal - provides precise clock source for all timing-critical NFC protocols. |
| VMID | Internal Reference Voltage | Provides stable mid-supply reference (≈VDD/2) for analog circuit biasing - critical for consistent RX sensitivity and modulation accuracy. |
Key Features

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 + firmware stack; single-chip solution with embedded host processor; lower RF output power (150 mW vs 200 mW). | Reduces host MCU firmware burden but lacks raw analog flexibility; not AEC-Q100 qualified. | Choose PN7150B0HN/C1 for rapid prototyping where full stack offload is prioritized over industrial temperature range or analog tuning control. |
| ST25R3916B | Higher RF output (250 mW); extended 13.56 MHz reader range (up to 70 mm); supports ISO/IEC 15693 and NFC-V; no MIFARE Classic licensing. | Better suited for long-range asset tracking or multi-standard inventory readers; requires separate crypto licensing for MIFARE. | Choose ST25R3916B when >50 mm read distance or ISO/IEC 15693 support is required, and MIFARE Classic usage is not mandatory. |
Compared with PN7150B0HN/C1 and ST25R3916B, the PN512AA0HN1/C2 uniquely combines AEC-Q100 Grade 3 qualification, MIFARE Classic IP licensing, and full analog configurability - making it the only option for automotive-grade, license-compliant, and field-tunable NFC reader designs.

FAQ
What is the qualified operating temperature range for PN512AA0HN1/C2?
The PN512AA0HN1/C2 is AEC-Q100 Grade 3 qualified with a specified ambient temperature range of −40 °C to +90 °C. This industrial-grade rating is confirmed in Section 3 (Quick reference data) of the official datasheet Rev. 5.2 and applies specifically to the PN512AA0HN1/C2 variant in HVQFN32 packaging. The wider range distinguishes it from commercial versions like PN5120A0HN1/C2 (−30 °C to +85 °C). PN512AA0HN1/C2 must be used within these limits to maintain guaranteed RF performance and reliability.
Does PN512AA0HN1/C2 support MIFARE Classic encryption natively?
Yes, PN512AA0HN1/C2 includes licensed NXP MIFARE Classic Crypto-1 intellectual property as stated in Section 2 (Features and benefits). This allows the IC to perform authenticated read/write operations on MIFARE Classic 1K/4K cards in Reader/Writer mode without requiring external crypto hardware or software licensing. The encryption engine is implemented in hardware and controlled via dedicated registers - PN512AA0HN1/C2 handles all cryptographic calculations internally during MIFARE transactions.
Which host interfaces are available on PN512AA0HN1/C2?
PN512AA0HN1/C2 supports SPI (up to 10 Mbit/s), I²C (Fast mode up to 400 kBd, High-speed mode up to 3400 kBd), and UART (RS232-level, up to 1228.8 kBd). The 8-bit parallel interface is explicitly unavailable in the HVQFN32 package per Table 3 (Pin description) footnote. Pins D1–D7 and A0/A1 retain secondary functions for I²C addressing or test signals, but do not constitute a functional parallel bus in PN512AA0HN1/C2.
What is the maximum RF output power capability of PN512AA0HN1/C2?
PN512AA0HN1/C2 delivers up to 200 mW RF output power into a 40 Ω matched antenna load, as verified by typical TX1/TX2 current draw of 60–100 mA at TVDD = 3 V (Table 1, IDD(TVDD)). This output level enables typical operating distances of up to 50 mm in Reader/Writer mode and 100 mm in Card Operation mode, contingent on antenna size, tuning, and field strength. No external power amplifiers are needed for standard NFC applications.
Is PN512AA0HN1/C2 pin-compatible with other PN512 variants?
PN512AA0HN1/C2 shares identical pinout and footprint with PN5120A0HN1/C2 and PN5120A0HN1/C1 in the HVQFN32 (SOT617-1) package, as confirmed by Figures 3 and 6.1–6.2 in the datasheet. However, it is not pin-compatible with HVQFN40 or TFBGA64 variants due to differing pin counts and layouts. All HVQFN32 variants use the same 32-pin configuration, enabling mechanical drop-in replacement where AEC-Q100 qualification is not required.
