Getting started with the X-NUCLEO-NFC04A1 NFC/RFID tag IC
expansion board based on ST25DV04K for STM32 Nucleo
Introduction
The X-NUCLEO-NFC04A1 dynamic NFC/RFID tag IC expansion board is based on the ST25DV04K
NFC Type V/RFID tag IC with a dual interface 4 Kbits EEPROM that also features an I²C interface. It
can be powered by the pin of Arduino connector or directly by the received carrier electromagnetic field.
The X-NUCLEO-NFC04A1 expansion board is compatible with the Arduino™ UNO R3 connector pin
assignment and can easily be plugged onto any STM32 Nucleo board. Various expansion boards can
also be stacked to evaluate different devices operating together with the dynamic NFC tag.
The board also features an antenna with a 54 mm iso 24.2 diameter, single layer, copper etched on
PCB.

1 Getting started
1.1 Hardware and software requirements
To operate correctly, the X-NUCLEO-NFC04A1 expansion board must be connected to the
STM32 Nucleo board as shown below.
Figure 2: X-NUCLEO-NFC04A1 expansion board plugged to an STM32 Nucleo board
The STM32 Nucleo firmware and the relative documentation are available at www.st.com.
The X-NUCLEO-NFC04A1 is designed to be used with any STM32 Nucleo board, even if
complete testing has been performed using the NUCLEO-L053R8 (based on the ultra-low
power STM32L053R8) and the NUCLEO-F401RE (hosting the dynamically efficient
STM32F401RE).
To use the STM32 Nucleo development boards with the X-NUCLEO-NFC04A1 expansion
board, the following software and hardware specifications are required:
a PC/Laptop with Microsoft Windows ® 7 and above to install the software package
(X-CUBE-NFC4)
a type A to Mini-B USB cable to connect the STM32 Nucleo board to the PC/Laptop
the X-CUBE-NFC4 software package (available on www.st.com)
1.2 Board setup
To set up the board:
1
Check that the jumper on the X-NUCLEO-NFC04A1 ST1 connector is in place.
This jumper provides the required voltage to the device on the boarda.
a
See Section 2.1.1: "Power supply option" for further details

2 Hardware description and configuration
The X-NUCLEO-NFC04A1 expansion board allows the user to test the functionality of the
ST25DV04K NFC Type V/RFID tag IC with a dual-interface 4 kBit electrically erasable
programmable read-only memory (EEPROM) that also features an I²C interface.
The EEPROM is organized in blocks of 512 bytes, arranged by pages of 4 bytes in I²C
mode, and in 128 blocks of 4 bytes in RF mode. It can be powered by STM32 Nucleo
board or directly by the received carrier electromagnetic field.
The ST25DV04K features a low power down (LPD) pin, a general purpose output (GPO)
and an energy harvesting feature that lets you output the energy coming from the RF field
on the Vout analog pin and acts on ST1 jumper to enable it.
The ST25DV04K can act as a mailbox in fast transfer mode in both directions between the
RF terminal (such as an e-reader or a smart phone) and the microcontroller through the
I²C. In this case, messages are stored in the RAM instead of EEPROM. This mode allows
exchanging up to 256 byte payload data via RF and I²C interfaces.
A user configurable output pin can also be used as an interrupt for the microcontroller, and
toggles during field change
a
(e.g., RF Busy, MailBox filled, EEPROM update, RF user
Interrupt and RF User Set/Reset).
ST25DV04K device standby current consumption can be further lowered using the Low
Power Down input pin that switches the ST25DV04K internal LDO off
b
.
These functions can be exploited using the firmware package contained in the X-CUBE-
NFC4 software
c
.
The STM32 Nucleo and the X-NUCLEO-NFC04A1 boards are connected through
connectors CN5, CN6, CN8 and CN9, as detailed in the following tables.

2.1 Power supply and GPIO connection options
2.1.1 Power supply option
The on-board jumper (ST1) allows the user to select the ST25DV power source: external
(STM32 Nucleo board power supply) or ST25DV energy harvesting, indicated on the board
silkscreen with 3.3 V and EH respectively.

2.1.2 GPIO option
The ST25DV_LPD and ST25DV_GPO optional signals can be disconnected from the
STM32 Nucleo board by removing, respectively, R11 and R1 resistors.
The same option applies to the lines driving the three general purpose LEDs (MCU_LED1,
MCU_LED2 and MCU_LED3) that can be dedicated to other purposes (by removing R2,
R3 and R4, respectively)
