Product details

Overview

X-NUCLEO-NFC04A1 from STMicroelectronics is an expansion board for STM32 Nucleo platforms based on the ST25DV04K dynamic NFC/RFID tag IC, featuring 4-Kbit dual-interface EEPROM, I²C interface, energy harvesting capability, and ISO/IEC 15693-compliant 54 mm circular antenna - used for rapid prototyping of contactless data exchange in smart labels and IoT edge nodes.

For engineers reviewing the X-NUCLEO-NFC04A1 datasheet, X-NUCLEO-NFC04A1 pinout, X-NUCLEO-NFC04A1 application, or X-NUCLEO-NFC04A1 equivalent, key selection criteria include Arduino UNO R3 connector compatibility, ST25DV04K-based I²C+RF dual-interface operation, NDEF message support, FCC/IC regulatory certification, and stackable board architecture for multi-tag system evaluation.

Technical Context

The board implements the ST25DV04K IC in Type V (ISO/IEC 15693) RFID mode with I²C host control, supporting fast transfer mode and field-change-triggered interrupts. It enables bidirectional communication between STM32 MCU and NFC-enabled smartphones or readers via RF coupling or wired I²C.

Energy harvesting is implemented through the V_E_H pin, delivering regulated voltage to external circuitry when RF field strength exceeds threshold; otherwise, V_E_H enters high-Z state. The board uses a single-layer 54 mm diameter PCB antenna optimized for 13.56 MHz operation and compliant with ISO/IEC 14443-A/B and ISO/IEC 15693 standards.

FAQ

Does X-NUCLEO-NFC04A1 require external firmware to operate with STM32 Nucleo?

Yes - it requires ST's free STM32Cube expansion package (X-CUBE-NFC3) containing HAL drivers, middleware, and NDEF examples. The board itself has no onboard processor; all logic runs on the host STM32 MCU via I²C, with ST25DV04K handling RF protocol stack and memory management.

Can X-NUCLEO-NFC04A1 be powered solely by RF field without external supply?

Yes - the ST25DV04K IC supports true energy harvesting: when exposed to sufficient 13.56 MHz RF field strength, it powers internal circuitry and delivers up to 3 V on the V_E_H pin. Below threshold, V_E_H goes high-Z and RF-only operation continues using harvested energy only.

What interrupt events does the ST25DV04K on this board support?

It supports six configurable RF-triggered interrupts: Field Change, RF Busy, Mailbox Full, E² Update Complete, RF User Interrupt, and RF User Set/Reset - routed to the ST25DV_GPO pin and usable for wake-up or event notification to the STM32 host MCU.

Is antenna tuning required before using X-NUCLEO-NFC04A1?

No - the 54 mm circular PCB antenna is pre-tuned and factory-validated for 13.56 MHz operation per ISO/IEC 15693. No external matching components or calibration are needed; performance meets FCC/IC radiated emission limits out-of-box when used per layout guidelines.
