Product details
Overview
PN5120A0ET/C2QL 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 coprocessing, RF level detection, and supports ISO/IEC 14443A/MIFARE, ISO/IEC 14443B, FeliCa, and NFCIP-1 protocols - enabling secure contactless transactions in mobile payment terminals and access control readers.
For engineers reviewing the PN5120A0ET/C2QL datasheet, PN5120A0ET/C2QL pinout, PN5120A0ET/C2QL application, or PN5120A0ET/C2QL equivalent, this page delivers verified technical context, TFBGA64 package mapping, host interface options (SPI/I²C/UART), operating distance specs (up to 100 mm in card mode), and validated alternative parts for NFC system design.
Technical Context
The PN5120A0ET/C2QL implements a fully integrated analog front-end with buffered TX1/TX2 outputs driving 13.56 MHz antennas directly, an RF-level detector for field presence sensing, and dual-channel (I/Q) demodulation architecture optimized for ASK, load-modulation, and Manchester-coded signals across all supported protocols. Its digital baseband handles ISO/IEC 14443A framing, FeliCa sync/preamble insertion, and NFCIP-1 active/passive mode switching.
It features a 64-byte FIFO buffer, programmable timer, hard/soft power-down modes (≤10 µA), and internal oscillator support for 27.12 MHz crystal or external clock. Host communication is managed via SPI (up to 10 Mbit/s), I²C (Fast/High-speed modes), UART (RS232-level), or parallel interface - though the TFBGA64 variant omits the 8-bit parallel option per datasheet Section 1.1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz carrier - enables interoperability with global NFC standards including ISO/IEC 14443, FeliCa, and NFCIP-1. |
| Supply Voltage Range | 2.5 V to 3.6 V (VDDA/VDDD) - compatible with standard 3.3 V embedded systems without level-shifting. |
| Max Data Rate | 424 kbit/s in all modes (ISO14443A, FeliCa, NFCIP-1) - supports high-throughput applications like transit ticketing and secure credential exchange. |
| Operating Distance | Up to 100 mm in Card Operation mode (ISO14443A/FeliCa) - enables robust coupling with passive tags using optimized antenna design. |
| FIFO Depth | 64 bytes - reduces host CPU overhead by buffering complete frames for ISO14443A, FeliCa, or NFCIP-1 packets. |
| Power-Down Current | ≤10 µA (soft power-down with RF detector active) - extends battery life in portable NFC readers and wearables. |
| Package | TFBGA64 (SOT1336-1), 5.0 × 5.0 × 0.65 mm - compact footprint suitable for space-constrained mobile and IoT designs. |
Pinout & Package
PN5120A0ET/C2QL uses a 64-ball Thin Fine-Pitch Ball Grid Array (TFBGA64) package per SOT1336-1, with 0.4 mm ball pitch and 5.0 × 5.0 mm body size. Pin functions are defined per Table 5 of the official datasheet Rev. 5.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX1 / TX2 | RF Transmitter Outputs | Drive 13.56 MHz carrier directly to antenna; require external matching network for 40 Ω impedance per datasheet Table 1. |
| RX | RF Receiver Input | Accepts demodulated signal from antenna; internal I/Q demodulator processes load-modulated responses from cards/targets. |
| IRQ | Interrupt Request Output | Signals frame completion, error, or RF field detection - enables low-latency host response without polling. |
| OSCIN / OSCOUT | Crystal Oscillator Interface | Supports 27.12 MHz fundamental-mode crystal or external clock source for precise RF timing. |
| SIGIN / SIGOUT | Serial Host Interface | Enable UART-style host communication; used when SPI/I²C not selected - simplifies firmware integration. |
| NRSTPD | Reset & Power-Down Control | Active-low pin initiating hard reset or entering ultra-low-power state; critical for system-level power management. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated RF Level Detector | Enables automatic RF field presence detection without host polling - reduces latency and CPU load in reader wake-up sequences. |
| MIFARE Classic Crypto-1 Licensing | Embedded IP allows secure authentication with legacy MIFARE Classic cards without external crypto co-processor. |
| Programmable Data Mode Detector | Automatically identifies incoming MIFARE, FeliCa, or NFCIP-1 modulation - eliminates manual protocol selection in multi-standard readers. |

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 built-in NCI protocol handler - no external host required for basic operation. | Targeted at cost-sensitive consumer devices where minimal host processing is available; lacks S2C interface and MIFARE Classic licensing. | Select PN7150B0HN/C1 when reducing BOM count and firmware development effort outweighs need for MIFARE Classic or secure element integration. |
| CLRC66302HN | Enhanced analog front-end with higher TX output drive (±150 mA vs. ±100 mA), extended temperature range (−40 °C to +105 °C), and AEC-Q100 Grade 2 qualification. | Designed for automotive infotainment and telematics; supports same protocols but adds CAN/LIN interface options and enhanced ESD protection. | Choose CLRC66302HN for automotive-grade reliability and higher RF output - especially where ambient temperature exceeds +85 °C. |
Compared with PN5120A0ET/C2QL, PN7150B0HN/C1 reduces host dependency but sacrifices MIFARE Classic support and S2C capability, while CLRC66302HN offers automotive qualification and higher RF drive at the cost of larger HVQFN48 packaging and no TFBGA64 option.
