Getting started with the NFC card reader expansion board based on ST25R3916B for STM32 and STM8 Nucleos

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, FeliCaTM, 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.

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.

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.

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

The X-CUBE-NFC6 firmware and the related documentation are available at www.st.com.

Board setup

To set up the board:
Step 1. Connect the X-NUCLEO-NFC08A1 expansion board to the STM32 Nucleo board from the top through the Arduino UNO R3 connectors
Step 2. Power the STM32 Nucleo board using a Mini-B USB cable
Step 3. Program the firmware on the STM32 Nucleo board using the provided example
Step 4. Reset the MCU using the reset button available on the STM32 Nucleo board. The evaluation kit is ready to be used.

Hardware

The X-NUCLEO-NFC08A1 expansion board allows the user to test the functionality of the ST25R3916B, which supports the reader/writer and the card emulation modes.
The ST25R3916B IC module and the STM32 Nucleo board are connected through CN5, CN6, CN8 and CN9 connectors (see the tables below).
