Getting started with the NFC card reader expansion board based on ST25R3916
for STM32 and STM8 Nucleos
Introduction
The X-NUCLEO-NFC06A1 NFC card reader expansion board is based on the ST25R3916 device.
The expansion board is configured to support ISO14443A/B, ISO15693, FeliCa™ and AP2P communication.
The ST25R3916 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 T
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 operations close to metallic parts and/or in changing environments.

1.2 Board connection
Connect the X-NUCLEO-NFC06A1 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 if 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.
1.3 Hardware requirements
The X-NUCLEO-NFC06A1 expansion board is designed to be used with any STM32 Nucleo
