STMicroelectronics X-STM32MP-NFC08

Overview

X-STM32MP-NFC08 from STMicroelectronics is an NFC card reader evaluation board built around the ST25R3916B high-performance NFC universal IC. It features a 47 × 34 mm four-turn 13.56 MHz PCB-etched antenna, SPI/I²C/GPIO interface to STM32MP157F-DK2 and STM32MP135F-DK, EEPROM-based automatic GPIO/driver setup, and six user LEDs with one tactile switch for interactive prototyping in secure access and payment validation systems.

For engineers reviewing the X-STM32MP-NFC08 datasheet, X-STM32MP-NFC08 pinout, X-STM32MP-NFC08 application, or X-STM32MP-NFC08 equivalent, this board enables rapid integration of ISO 14443A/B, FeliCa™, ISO 15693, and active/passive NFC-A/F/V modes into Linux-based embedded platforms using standard 40-pin GPIO headers compatible with Raspberry Pi layouts.

Technical Context

The X-STM32MP-NFC08 implements a complete NFC front-end subsystem centered on the ST25R3916B, which integrates an analog front end (AFE) supporting 13.56 MHz carrier generation, adaptive antenna tuning (AAT), and EMI filtering. It delivers up to 53 kbps ISO 15693 read rates and supports all major NFC protocols including initiator, target, reader, and card emulation modes.

Interface connectivity uses dedicated SPI (MOSI/MISO/CLK/CS), I²C (SCL/SDA/EN), and GPIO lines (IRQ, LED control, switch input) routed to a 40-pin expansion header. The board includes M24C32-RMN6TP EEPROM for persistent configuration storage and onboard 27.12 MHz crystal timing reference for ST25R3916B clocking.

FAQ

Does X-STM32MP-NFC08 require external firmware or drivers?

No. The board operates with ST's official ST25R3916B middleware and STM32CubeMP1 software package. Pre-integrated Linux kernel drivers and userspace libraries are provided for STM32MP1 series, enabling immediate NFC protocol handling without custom low-level firmware development.

Can X-STM32MP-NFC08 be used with non-ST host processors?

Yes - its 40-pin GPIO header follows Raspberry Pi mechanical and signal layout conventions. Any host platform supporting 3.3 V logic, SPI/I²C, and interrupt-capable GPIO can interface with it, though ST-provided software support is optimized for STM32MP1 Linux environments.

What is the maximum read range achievable with the onboard antenna?

Measured performance shows up to 65 mm read distance with ISO 14443A cards (e.g., MIFARE Classic) under optimal alignment and low-noise conditions. Range varies with tag type, orientation, and environmental EMI; antenna tuning components (AAT_PARALLEL/AAT_SERIES) allow fine adjustment for specific use cases.

Is the EEPROM pre-programmed with default configuration?

Yes. The M24C32-RMN6TP EEPROM contains factory-loaded GPIO mapping and ST25R3916B initialization sequences. This enables plug-and-play operation on supported DK boards; users may reprogram it via I²C to customize LED behavior, IRQ polarity, or peripheral enable states.
