X-NUCLEO-NFC01A1

UM1793 User manual 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 I2C interface • a 13.56 MHz RFID reader or a NFC phone. The I2C 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 I2C 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. The X-NUCLEO-NFC01A1 (MB1163) schematics, BOM, gerber files, drivers and firmware are available for download on www.st.com. Figure 1.

It is a dynamic NFC/RFID tag IC. It features a 64 Kbit EEPROM memory, preformatted for NFC transactions, and which can be protected by a unique and flexible 128-bit password scheme. The memory bank can be accessed by any of its two interfaces, either from an I2C interface or by a 13.56 MHz passive NFC interface. The I2C interface is a two-wire serial interface, consisting of a bidirectional data line and a clock line. It behaves as a slave with respect to the I2C protocol. The NFC interface is based on the ISO/IEC 14443 type A and NFC Forum type 4 tag specifications. Because it is a passive RF interface, it operates when the board is powered on but also when the board is powered off. Two control pins are also available from the M24SR64-Y chip, allowing flexible management of the NFC interface. 2/9 DocID026566 Rev 2 UM1793 2 Features Features Ready-to-use printed circuit board (PCB) including: • M24SR64-Y dynamic NFC/RFID tag • 31 mm x 30 mm 13.56 MHz double layer inductive antenna etched on the PCB (ANT14) • Different color LEDs • Arduino UNO R3 connectors for Nucleo Board.
