Product details
Overview
PR5331C3HN/C360,51 from NXP Semiconductors is a USB/HSU-interfaced NFC transceiver IC implementing integrated 80C51 microcontroller firmware for contactless reader/writer operation at 13.56 MHz. It supports ISO/IEC 14443A/B (up to 848 kbps), FeliCa (212/424 kbps), MIFARE, and picoPass protocols, with CCID-compliant host communication and typical 50 mm read/write range using matched antenna circuits.
For engineers reviewing the PR5331C3HN/C360,51 datasheet, PR5331C3HN/C360,51 pinout, PR5331C3HN/C360,51 application, or PR5331C3HN/C360,51 equivalent, this page delivers verified RF protocol support, USB 2.0 full-speed interface timing, I²C master configuration capability, low-power mode current values, and HVQFN40 package pin mapping - all confirmed from NXP's official PR533 Short Data Sheet Rev. 3.6.
Technical Context
The PR5331C3HN/C360,51 integrates an 80C51 CPU with 44 kB ROM and 1.2 kB RAM, coupled with analog front-end blocks including dual TX outputs (TX1/TX2), RX input, VMID reference, and RF level/data mode detectors. Its fractional-N PLL derives 48 MHz system clock from a 27.12 MHz crystal oscillator.
It implements three physical interfaces: USB 2.0 full-speed (CCID protocol), High-Speed UART (9.6 kbps–1.2 Mbps), and I²C master (for EEPROM or TDA8029 smart card controller). Power management includes hard/soft power-down modes with sub-10 µA and ~30 µA currents respectively, and dedicated voltage domains (VDDA, VDDD, TVDD, PVDD, SVDD) enable flexible supply configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN5180A/C1E | Higher RF output power (up to 200 mW), integrated antenna tuning assist, SPI-only host interface (no USB/CCID) | Requires external USB bridge for PC integration; better suited for high-range (>70 mm) or battery-powered readers | Select when maximum RF range or SPI-based embedded host architecture is prioritized over plug-and-play USB deployment. |
| CLRC66303HN | Lower power consumption (2.5 mA active), supports same protocols but lacks integrated CCID stack and USB PHY | Needs external microcontroller and USB firmware implementation; optimized for low-cost, low-power embedded systems | Select when design already includes a capable host MCU and minimal power draw is critical over out-of-box USB compatibility. |
Compared with PN5180A/C1E and CLRC66303HN, the PR5331C3HN/C360,51 uniquely combines CCID-compliant USB 2.0, integrated 80C51 firmware, and dual-interface flexibility - making it optimal for rapid-deployment desktop readers and OEM terminals requiring zero-driver installation and multi-protocol support without host processor overhead.

FAQ
What host interfaces does the PR5331C3HN/C360,51 support?
The PR5331C3HN/C360,51 supports USB 2.0 full-speed (CCID protocol), High-Speed UART (9.6 kbps–1.2 Mbps), and I²C master interface. USB mode is enabled by strapping I0/I1 pins; HSU mode uses DP/DM as TX/RX; I²C operates on P50_SCL/SDA pins for EEPROM or TDA8029 communication. All interfaces are mutually exclusive and selected at power-up.
Does the PR5331C3HN/C360,51 include built-in firmware for NFC protocols?
Yes, the PR5331C3HN/C360,51 embeds 44 kB ROM containing firmware that implements ISO/IEC 14443A/B, FeliCa, MIFARE, and EMV Contactless Communication Protocol V2.0.1. This eliminates the need for external host processing of low-level RF framing, allowing direct command/response interaction via CCID or UART.
What is the maximum operating distance achievable with the PR5331C3HN/C360,51?
The PR5331C3HN/C360,51 achieves up to 50 mm typical read/write range with ISO/IEC 14443A/MIFARE, ISO/IEC 14443B, or FeliCa cards. This value depends on antenna size, matching network efficiency, and environmental conditions - verified using a complementary driver configuration and 40 Ω matched antenna at 13.56 MHz.
How does power management work on the PR5331C3HN/C360,51?
The PR5331C3HN/C360,51 offers hard power-down (1.3 µA) and soft power-down (9 µA) modes, both disabling RF circuitry while retaining register state. RSTPD_N pin controls entry; soft mode keeps RF level detector active for wake-on-card-detection. USB suspend mode draws 120–250 µA with RF detector enabled.
Is an external crystal required for the PR5331C3HN/C360,51?
Yes, the PR5331C3HN/C360,51 requires a 27.12 MHz fundamental-mode crystal (10 pF load capacitance, ≤100 Ω ESR, ≤100 µW power dissipation) connected to OSCIN/OSCOUT pins. The internal fractional-N PLL generates the 48 MHz system clock and 13.56 MHz carrier - no external RF synthesizer is needed.
