Product details
Overview
PR5331C3HN/C370E from NXP Semiconductors is a USB/HSU-interfaced NFC transceiver module integrating an 80C51 microcontroller, RF front-end, and CCID-compliant host interface for contactless reader/writer systems operating at 13.56 MHz. It supports ISO/IEC 14443A/B (up to 848 kbps), FeliCa (212/424 kbps), MIFARE, and picoPass protocols, with typical read/write range up to 50 mm using matched antenna circuits.
For engineers reviewing the PR5331C3HN/C370E datasheet, PR5331C3HN/C370E pinout, PR5331C3HN/C370E application, or PR5331C3HN/C370E equivalent, this page delivers verified electrical parameters, HVQFN40 package mapping, I²C master and dual UART interface capabilities, EMV Contactless V2.0.1 compliance, and low-power mode current values - all confirmed from NXP's official PR533 Short Data Sheet Rev. 3.6.
Technical Context
The PR5331C3HN/C370E implements a dedicated ROM-based firmware architecture with integrated 44 kB ROM and 1.2 kB RAM, enabling protocol handling for PCD-mode NFC communication without external host processing overhead. Its analog front-end includes buffered TX1/TX2 drivers, integrated RF level and data mode detectors, and antenna presence self-test circuitry with programmable current thresholds.
It operates in USB 2.0 full-speed (bus- or host-powered) or HSU (9.6 kbps–1.2 Mbps) host interface modes, with CCID protocol stack execution on-chip. The I²C master interface supports configuration EEPROM (address A0h) or TDA8029 contact smart card reader control, while dedicated GPIOs (P30–P35, P70_IRQ) enable system-level event signaling and peripheral coordination.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7150B01HN/C1 | Lower integration: no embedded 80C51 core; requires external host processor for protocol handling. | Lacks on-chip CCID stack and EMV V2.0.1 firmware - mandates host-side driver and security stack implementation. | Choose when system already includes capable host MCU and requires smaller footprint or lower unit cost. |
| CLRC66302HN | Supports same RF protocols but lacks USB interface; only offers SPI/parallel host interface. | Requires external USB bridge IC (e.g., CP2102) for USB connectivity - increases BOM count and layout complexity. | Prefer when existing design uses SPI host interface or when USB is not required and higher RF sensitivity is prioritized. |
Compared with PN7150B01HN/C1 and CLRC66302HN, PR5331C3HN/C370E uniquely integrates CCID-compliant USB, embedded firmware, and dual-host flexibility - delivering fastest time-to-market for certified USB NFC readers without host software development.

FAQ
What host interfaces does the PR5331C3HN/C370E support?
The PR5331C3HN/C370E supports USB 2.0 full-speed (bus- or host-powered) and High-Speed UART (9.6 kbps–1.2 Mbps) host interfaces. Interface selection is controlled by strap pins I0 and I1. USB mode implements the CCID protocol natively, while HSU mode uses a transparent serial protocol. Both interfaces are fully supported in the PR5331C3HN/C370E firmware without external configuration.
Does the PR5331C3HN/C370E include an integrated microcontroller?
Yes, the PR5331C3HN/C370E integrates an 80C51-compatible microcontroller with 44 kB ROM and 1.2 kB RAM. This embedded core executes the RF protocol stack, CCID command parsing, antenna tuning algorithms, and power management - eliminating the need for an external host processor in many reader designs.
What is the maximum read/write distance achievable with the PR5331C3HN/C370E?
The PR5331C3HN/C370E achieves a typical read/write distance of up to 50 mm for ISO/IEC 14443A/MIFARE, ISO/IEC 14443B, and FeliCa cards. This performance depends on antenna size, matching network quality, and environmental conditions. The device includes integrated RF level detection and antenna presence self-test to ensure consistent field strength calibration.
Is the PR5331C3HN/C370E compliant with EMV Contactless specifications?
Yes, the PR5331C3HN/C370E in PCD mode is compliant with EMV Contactless Communication Protocol Specification V2.0.1. This compliance is implemented in firmware and verified through NXP's qualification process. Application-level Smart eID compliance is also achievable using the PR5331C3HN/C370E's protocol engine and secure I²C interface to external secure elements.
What power supply configurations does the PR5331C3HN/C370E support?
The PR5331C3HN/C370E supports two primary power configurations: USB bus power (4.02–5.25 V on VBUS) and non-USB mode (2.5–3.6 V on VDDD/VDDA/VDD(TVDD)). In USB mode, an internal regulator generates 3.3 V digital/analog supplies. In non-USB mode, separate 2.5–3.6 V supplies must be provided to each domain (DVDD, AVDD, TVDD, PVDD, SVDD). Total power dissipation is rated at ≤550 mW.
