ST X-NUCLEO-NFC08A1 Manuel utilisateur
Introduction
The X-NUCLEO-NFC08A1 NFC card reader expansion board is based on the ST25R3916B device.
The expansion board is configured to support ISO14443A/B, ISO15693, FeliCa™, and AP2P communication.
The ST25R3916B manages frame coding and decoding in reader mode for standard applications, such as NFC,
proximity, and vicinity HF RFID standards. It supports ISO/IEC 14443 type A and B, ISO/IEC 15693 (single
subcarrier only) and ISO/IEC 18092 communication protocols as well as the detection, reading and writing of NFC
forum type 1, 2, 3, 4, and 5 tags.
The on-board low-power capacitive sensor performs ultra-low power wake-up without switching the reader field on
and traditional inductive wake-up to select amplitude or phase measurement.
The automatic antenna tuning (AAT) technology enables operation close to metallic parts and/or in changing
environments.

• ISO 15693
• FeliCa™
• Up to 1.7 W output power with differential antenna
• Possibility of driving two antennas in single-ended configuration
• Inductive wake-up
• Automatic antenna-tuning system
• Transparent and stream modes to implement MIFARE™ classic compliant or other custom protocols
• Equipped with Arduino UNO R3 connector
• Free comprehensive development firmware library compatible with STM32Cube and samples for
ST25R3916B
• Scalable solution for multiple board cascade
• FCC certified
• RoHS and WEEE compliant
1.2 Board connection
Connect the X-NUCLEO-NFC08A1 to an STM32 Nucleo-64 development board via Arduino UNO R3 connectors.
The PC USB port has to be capable of delivering at least 300 mA at 5 V supply.
A green LED indicates whether the 5 V supply is present, while the six status LEDs are controlled via MCU.
Provision for unpopulated jumpers enable alternative connections of all lines (except the SPI) to the STM32 MCU.
To demonstrate the wake-up feature, two capacitive electrodes are placed on the PCB and the automatic antenna
tuning variable capacitors are also implemented.
The board is connected to a power supply. It should be used on a clean and non-flammable surface.
1.3 Hardware requirements
The X-NUCLEO-NFC08A1 expansion board is designed to be used with any STM32 Nucleo board, although
complete testing has been performed using the NUCLEO-L476RG hosting the STM32L476RG microcontroller.
The STM32 Nucleo firmware and the related documentation are available at http://www.st.com/stm32nucleo.
1.4 System requirements
To use STM32 Nucleo boards with the X-NUCLEO-NFC08A1 expansion board the following software and
hardware are required:
• an STM32 Nucleo-64 development board
• a Windows® PC to install the firmware package
• a USB type A to Mini-B USB cable to connect the STM32 Nucleo board to the PC
• the unit must be supplied by a safety extra low voltage with falling characteristics (<5 V, <15 W), according
to EN60950-1. This power supply has to be classified as ES1 (Electrical Source1), PS1 according to
EN62368-1
To install the board firmware package (order code: X-CUBE-NFC6) the PC must have:
• 128 MB of RAM
• 40 MB of free hard disk space
