Product details
Overview
PR5331C3HN/C350,55 from NXP Semiconductors is a USB/HSU-interfaced NFC transceiver IC implementing integrated 80C51 microcontroller, RF front-end, and CCID protocol stack for contactless reader/writer systems 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 distance up to 50 mm using matched antenna - deployed in secure access terminals and EMV-compliant payment kiosks.
For engineers reviewing the PR5331C3HN/C350,55 datasheet, PR5331C3HN/C350,55 pinout, PR5331C3HN/C350,55 application, or PR5331C3HN/C350,55 equivalent, key selection factors include its dual-interface support (USB 2.0 full-speed + HSU), embedded ROM-based protocol handling, I²C master capability for EEPROM or TDA8029 integration, low-power modes (hard/soft power-down), and compliance with EMV Contactless Communication Protocol V2.0.1.
Technical Context
The PR5331C3HN/C350,55 integrates an 80C51 CPU with 44 kB ROM and 1.2 kB RAM, a fractional-N PLL for precise 13.56 MHz carrier generation, and analog front-end blocks including buffered TX1/TX2 drivers, RX input with internal VMID reference, and integrated RF/data mode detectors. Its firmware implements PCD-mode protocol stacks for multiple standards without host-side processing overhead.
It operates across two primary power domains: USB bus-powered mode (VBUS = 4.02–5.25 V) and non-USB mode (VDDD/VDDA/VDD(TVDD) = 2.5–3.6 V), with dedicated SVDD output for SAM power control and PVDD supply for interface I/Os. Antenna presence detection is performed via IVDDD current thresholds, configurable through register bits andet_ithl[1:0] and andet_ithh[2:0].

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN5180A/C1 | Higher RF output power (up to 1.2 W), integrated 32-bit ARM Cortex-M0+, supports NFC Forum LLCP and SNEP - lacks native CCID/PC/SC support. | Targeted at Android Things and Linux-based IoT gateways requiring peer-to-peer or card emulation; not drop-in for Windows PC/SC environments. | Select when needing advanced NFC controller features beyond reader/writer mode - requires full firmware development and USB CDC/ACM driver integration. |
| CLRC66303HN | Same HVQFN40 package, 13.56 MHz analog front-end, but no embedded microcontroller - requires external host MCU to run protocol stack. | Suitable for deeply embedded systems where host MCU already implements ISO14443/FeliCa stacks; no CCID or USB interface built-in. | Choose for cost-sensitive, MCU-rich designs where protocol flexibility and firmware control outweigh USB plug-and-play convenience. |

The PR5331C3HN/C350,55 supports Microsoft Windows 2000 through Windows 7 (32/64-bit), Windows Server editions, and GNU/Linux (via PC/SC-Lite with libusb 1.0.x), Mac OS Leopard/Snow Leopard, Solaris, and FreeBSD. Its CCID compliance enables plug-and-play operation without custom driver development on all listed platforms - the PR5331C3HN/C350,55 enumerates as a standard smart card reader device.
Does the PR5331C3HN/C350,55 require an external microcontroller to operate?
No, the PR5331C3HN/C350,55 contains an integrated 80C51 microcontroller with 44 kB ROM and 1.2 kB RAM that executes all RF protocol stacks (ISO/IEC 14443A/B, FeliCa, MIFARE) and CCID command handling internally. The host only sends/receives APDUs via USB or HSU - no external MCU is needed for basic reader/writer functionality. The PR5331C3HN/C350,55 is a complete standalone NFC controller.
How is antenna tuning and presence detection handled in the PR5331C3HN/C350,55?
The PR5331C3HN/C350,55 implements antenna presence detection by monitoring IVDDD supply current thresholds (configurable from 5 mA to 150 mA via andet_ithl/andet_ithh registers). It also includes integrated RF level and data mode detectors to validate signal integrity during communication. These features enable automatic antenna fault reporting and eliminate need for external sensing circuitry - critical for maintenance-free deployment of the PR5331C3HN/C350,55 in unattended kiosks.
Can the PR5331C3HN/C350,55 interface with a contact smart card reader?
Yes, the PR5331C3HN/C350,55 includes a master I²C-bus interface (P50_SCL/SDA) that can directly control the TDA8029 contact smart card reader IC. When configured as I²C master, the PR5331C3HN/C350,55 manages power sequencing, clock generation, and data exchange - enabling hybrid contact/contactless terminals using a single PR5331C3HN/C350,55 controller and shared host processor.
What is the role of the DELATT pin on the PR5331C3HN/C350,55?
The DELATT pin (Pin 27) provides an optional output for connecting an external 1.5 kΩ pull-up resistor to DP (USB D+), which is required for USB device enumeration. When enabled, DELATT simplifies USB interface design by eliminating need for manual resistor placement - ensuring reliable host recognition during PR5331C3HN/C350,55 startup. This pin is inactive in HSU mode.
