STMicroelectronics X-NUCLEO-NFC07A1

Overview

X-NUCLEO-NFC07A1 from STMicroelectronics is an Arduino UNO R3–compatible expansion board for STM32 Nucleo platforms, integrating the ST25DV64KC dynamic NFC/RFID tag IC with 64-Kbit dual-interface EEPROM, I²C interface, and energy harvesting capability. It enables NFC-based data exchange, secure configuration, and batteryless operation in embedded systems.

For engineers reviewing the X-NUCLEO-NFC07A1 datasheet, X-NUCLEO-NFC07A1 pinout, X-NUCLEO-NFC07A1 application, or X-NUCLEO-NFC07A1 equivalent, key selection criteria include I²C compatibility with STM32 Nucleo, 54 mm PCB-etched antenna performance, self-powered operation via RF field, and support for NDEF messaging and multi-event interrupt handling.

Technical Context

The board implements a Type V NFC Forum tag (ST25DV64KC) with dual-interface memory: contactless RF (13.56 MHz) and wired I²C (up to 1 MHz). It supports fast transfer mode for high-speed data exchange between host MCU and tag memory.

Energy harvesting is enabled via the V_EH pin, delivering regulated voltage from RF field strength ≥ 1.5 A/m; VOUT enters high-Z when field drops below threshold or harvesting is disabled. Interrupt outputs (GPO) signal six configurable events including field change, mailbox fill, and EEPROM update completion.

FAQ

Does X-NUCLEO-NFC07A1 require external power to operate?

No. The board operates in two modes: powered via the STM32 Nucleo board's 3.3 V rail through Arduino UNO R3 connectors, or autonomously via energy harvesting from the RF field. When sufficient RF field strength (>1.5 A/m) is present, the ST25DV64KC delivers regulated voltage on V_EH, enabling fully batteryless operation for data read/write and interrupt signaling.

Which STM32 Nucleo boards are compatible with X-NUCLEO-NFC07A1?

X-NUCLEO-NFC07A1 is mechanically and electrically compatible with all STM32 Nucleo-64 and Nucleo-144 boards featuring Arduino UNO R3 connectors (e.g., NUCLEO-F401RE, NUCLEO-L476RG, NUCLEO-H743ZI2). It uses dedicated I²C pins (SCL/SDA), GPO, and power rails mapped to standard Arduino layout, ensuring plug-and-play integration without jumpering or modification.

Can multiple X-NUCLEO-NFC07A1 boards be stacked on one Nucleo board?

Yes. The board supports stacking with other X-NUCLEO expansion boards using standardized Arduino UNO R3 and ST morpho headers. I²C bus sharing is supported via pull-up resistors on each board; users must ensure unique I²C addresses (ST25DV64KC supports A0/A1/A2 address pins) and avoid GPO pin conflicts when cascading for multi-tag or distributed NFC node evaluation.

What development resources are provided for X-NUCLEO-NFC07A1?

ST provides the X-CUBE-NFC7 software expansion package for STM32Cube, including full HAL drivers, NDEF message parsing/writing APIs, energy harvesting control routines, and interrupt event handlers for all six GPO triggers. Example projects target multiple Nucleo boards and integrate with STM32CubeMX for rapid configuration of I²C, GPIO, and clock settings.
