Dynamic NFC tag expansion board based on M24SR
for STM32 Nucleo
Introduction
The X-NUCLEO-NFC01A1 is a demonstration kit to evaluate the features and capabilities of
the M24SR series. It is based on the M24SR64 device. This shield can be plugged on the
Arduino UNO R3 connectors of any STM32 Nucleo board. This module is compatible with
the following STM32 class of microcontrollers: STM32L0, STM32L1, STM32F0, STM32F1,
STM32F3, STM32F4.
The M24SR64 device is a dynamic NFC/RFID tag IC with a dual interface. It embeds a
64 Kbit EEPROM memory. It can be operated from:
• an I
2
C interface
• a 13.56 MHz RFID reader or a NFC phone.
The I
2
C interface uses a two-wire serial interface, consisting of a bidirectional data line and
a clock line. It behaves as a slave with respect to the I
2
C protocol.
The RF protocol is compatible with ISO/IEC 14443 Type A and NFC Forum Type 4 Tag.
The board is powered through the Arduino UNO R3 connectors. It also includes three LEDs
for general purpose.
