Product details
Overview
PR5331C3HN/C360,55 from NXP Semiconductors is a USB/HSU-interfaced NFC transceiver IC with integrated 80C51 microcontroller, supporting ISO/IEC 14443A/B (up to 848 kbps), FeliCa (212/424 kbps), MIFARE, and picoPass protocols at 13.56 MHz. It delivers up to 50 mm read/write distance with buffered RF drivers and operates from 2.5–3.6 V or USB 5 V bus power.
For engineers reviewing the PR5331C3HN/C360,55 datasheet, PR5331C3HN/C360,55 pinout, PR5331C3HN/C360,55 application, or PR5331C3HN/C360,55 equivalent, this page provides verified RF protocol support, CCID-compliant USB interface details, I²C master configuration for EEPROM/TDA8029, low-power modes, and HVQFN40 package-level design constraints.
Technical Context
The PR5331C3HN/C360,55 integrates an 80C51 CPU with 44 kB ROM and 1.2 kB RAM, executing protocol stacks for PCD-mode contactless communication. Its analog front end includes dual TX outputs (TX1/TX2), RX input, integrated RF level and data mode detectors, and a 27.12 MHz fractional-N PLL.
It supports three host interfaces: USB 2.0 full-speed (CCID class), HSU UART (9.6 kbps–1.2 Mbps), and I²C master (for external EEPROM at 0xA0 or TDA8029). Power management includes hard/soft power-down modes with sub-10 µA current draw and regulated SVDD output for SAM interfacing.

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 (1.5 W vs 0.55 W), integrated NFC controller (no 80C51), supports ISO14443A/B/F only - no FeliCa or MIFARE encryption. | Targeted at high-range (>70 mm) industrial readers; lacks built-in FeliCa/MIFARE crypto acceleration. | Choose PN5180A/C1E when maximum range and lower host processing load are prioritized over multi-protocol flexibility. |
| CLRC663P/041 | Same 80C51 core, 48 kB ROM, supports identical protocols but lacks USB CCID stack - requires host-side USB firmware implementation. | Used in embedded systems where host MCU handles USB enumeration and CCID command parsing. | Choose CLRC663P/041 when full USB stack offload is unnecessary and cost-sensitive BOM optimization is required. |
Compared with PN5180A/C1E and CLRC663P/041, PR5331C3HN/C360,55 uniquely combines certified CCID USB compliance, integrated FeliCa/MIFARE crypto, and 50 mm range in a single HVQFN40 package - making it optimal for plug-and-play EMV/FeliCa readers requiring zero host driver development.

FAQ
What host interfaces does the PR5331C3HN/C360,55 support?
The PR5331C3HN/C360,55 supports three host interfaces: USB 2.0 full-speed compliant with CCID class (enabling plug-and-play on Windows/macOS/Linux), High-Speed UART (9.6 kbps to 1.2 Mbps), and I²C master (for configuring external EEPROM or controlling TDA8029 contact readers). All interfaces are selectable via I0/I1 pins at power-up, and the PR5331C3HN/C360,55 handles protocol translation internally without host firmware intervention.
Does the PR5331C3HN/C360,55 support EMV Contactless v2.0.1 certification?
Yes, the PR5331C3HN/C360,55 implements the EMV Contactless Communication Protocol Specification v2.0.1 in ROM firmware and is designed to meet the RF and protocol requirements for Level 1 certification. Its PCD-mode operation, precise timing control, and built-in RF level detector ensure compliance - though final system-level certification requires validation of the complete reader module, including antenna design and enclosure.
What is the maximum operating distance achievable with the PR5331C3HN/C360,55?
The PR5331C3HN/C360,55 achieves up to 50 mm typical read/write distance with ISO/IEC 14443A/MIFARE, ISO/IEC 14443B, or FeliCa cards when paired with a properly tuned 40 Ω antenna connected between TX1 and TX2. This distance assumes optimal antenna geometry, matching network, and 3.3 V supply; performance decreases below 3 V or with mismatched antennas.
Can the PR5331C3HN/C360,55 operate without an external crystal oscillator?
No - the PR5331C3HN/C360,55 requires an external 27.12 MHz crystal oscillator connected to OSCIN/OSCOUT pins. The crystal must meet specified parameters: frequency tolerance ±13 kHz (27.107–27.133 MHz), ESR ≤100 Ω, and load capacitance 10 pF. An external clock source is not supported; the internal fractional-N PLL relies exclusively on this crystal for RF carrier generation and timing accuracy.
How does the PR5331C3HN/C360,55 handle power management in battery-powered applications?
The PR5331C3HN/C360,55 offers two ultra-low-power states: hard power-down (1.3 µA total current) and soft power-down (9 µA with RF level detector active). In soft mode, it detects incoming RF fields and wakes within microseconds - ideal for battery-powered access readers. Both modes retain register state and require no reinitialization upon wake, and the PR5331C3HN/C360,55 supports 2.5–3.6 V operation to maximize battery utilization.
