St Um2960 User manual

Introduction

The X-NUCLEO-NFC07A1 dynamic NFC/RFID tag IC expansion board is based on the ST25DV64KC dynamic NFC/RFID

tag IC with a 64-Kbit dual interface EEPROM and fast transfer mode feature. It can be powered through the STM32 Nucleo

development board or directly through the received carrier electromagnetic field.

The X-NUCLEO-NFC07A1 expansion board is compatible with the Arduino UNO R3 connector pin assignment and can easily

be plugged onto any STM32 Nucleo development board. You can stack other expansion boards to evaluate different devices

that work together with the dynamic NFC tag.

The board also features a single-layer antenna with a diameter of 54 mm and copper etched on the PCB.

The expansion board package with order code X-NUCLEO-NFC07A1 contains the X$NUCLEO-NFC07A board.

1Getting started

1.1 Hardware and software requirements

To operate correctly, connect the X-NUCLEO-NFC07A1 expansion board to an STM32 Nucleo development

board as shown below.

Figure 2. X-NUCLEO-NFC07A1 expansion board plugged to an STM32 Nucleo development board

The X-NUCLEO-NFC07A1 is designed to be used with any STM32 Nucleo development board, even if complete

testing has been performed using the NUCLEO-L053R8 (based on the STM32L053R8 ultra-low power Arm®

Cortex®-M0+ MCU) and the NUCLEO-F401RE (hosting the STM32F401RE dynamically efficient MCU based on

Arm® Cortex®-M4).

To use the STM32 Nucleo development boards with the X-NUCLEO-NFC07A1 expansion board, the following

software and hardware specifications are required:

• a PC or laptop with Microsoft Windows ® 7 and above to install the software package (X-CUBE-NFC7)

• a type A to mini-B USB cable to connect the STM32 Nucleo development board to your PC or laptop

• the X-CUBE-NFC7 software package

1.2 Board setup

To set up the board:

Step 1. Check that the jumper on the X-NUCLEO-NFC07A1 ST1 connector is in place.

This jumper provides the required voltage to the device on the board (see Section 2.1.1 Power supply

option for further details).

Step 2. Connect the X-NUCLEO-NFC07A1 on top of the STM32 Nucleo development board as shown in

Figure 2.

Step 3. Power the STM32 Nucleo development board using the Mini-B USB cable.

Step 4. Program the firmware in the STM32 Nucleo development board using the provided firmware example.

Step 5. Reset the MCU board using the reset button available on the STM32 Nucleo development board.

The evaluation kit is ready to be used.

2Hardware description and configuration

The X-NUCLEO-NFC07A1 expansion board allows the user to test the functionality of the ST25DV64KC dynamic

NFC/RFID tag IC with a 64-Kbit dual interface EEPROM.

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 through the STM32 Nucleo development board or directly through the

received carrier electromagnetic field.

The ST25DV64KC features 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 ST25DV64KC 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 (available even when RF is disabled) (e.g., RF Busy, MailBox filled, EEPROM update, RF user Interrupt

and RF User Set/Reset).

These functions can be exploited using the firmware package contained in the X-CUBE-NFC7 software.

Note: To program the microcontroller on the STM32 Nucleo board refer to user manuals UM1724," STM32 Nucleo-64

board", and UM1725, "Description of STM32F4 HAL and LL drivers", available on www.st.com.).

The STM32 Nucleo and the X-NUCLEO-NFC07A1 are connected through CN5, CN6, CN8, and CN9 connectors

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 (the power supply of the

STM32 Nucleo development board) or ST25DV energy harvesting, indicated on the board silkscreen with 3.3 V

and EH, respectively.

2.1.2 GPIO option

You can disconnect the ST25DV_GPO optional signal from the STM32 Nucleo development board by removing

R1.

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).

In case you modify these connections, update the firmware to enable proper use of the STM32 Nucleo resources.
