Getting started with ST25R3916-DISCO

Introduction

ST25R3916-DISCO is a ready-to-use development kit to evaluate the features and functionality in reader/writer, peer-to-peer and card emulation modes of the high-performance NFC universal device ST25R3916 for contactless applications.

The kit is composed of two boards:

• MB1396 (ST25_Discovery_Mboard): a microprocessor motherboard, which includes a complement of hardware and software tools enabling the use the full STM32 Nucleo ecosystem. The board is powered through USB connectors.

• MB1414 (ST25R3916_Discovery_DB): a daughter board, which embeds the ST25R3916 device and an antenna etched on the PCB with its tuning circuit.

The communication link between the two boards is the SPI bus and the processor card provides the power. Specific data lines complete the pin connector assignment shared between cards.

A variety of demonstrations can be performed with this kit, which allows the users to develop and test their applications.

The MB1396 and the MB1414 boards schematics, BOM, Gerber files, drivers and firmware are available on the STMicroelectronics website www.st.com

Description

2 Description

UM2358

The ST25R3916-DISCO kit allows the user to evaluate the features and capabilities of the

ST25R devices, a series of high performance HF readers.

The kit comes with application notes, software applications, drivers, BOM (bill of materials), board schematics, Gerber files and firmware schematics. All these documents can be downloaded from www.st.com

, they help the user to reduce the design efforts.

The kit is composed of two boards:

1.

The MB1396 (ST25_Discovery_Mboard) is a microprocessor motherboard embedding a 32-bit microcontroller of the STM32L476 line, based on Arm

®(a)

Cortex

®

-M4 high-performance CPU with FPU.

The MB1396 is powered through the USB bus. It includes:

– an ST-LINK in-circuit debugger and programmer for STM32 microcontrollers

– a 2.4” TFT LCD with touch screen capability

– LEDs

– push buttons (reset and user)

– a mini USB debug connector

– a user-dedicated micro USB connector.

– features for ST NFC TAG

2. The MB1414 (ST25R3916_Discovery_DB) daughter board, which embeds the

ST25R3916, an antenna etched on the PCB and its tuning circuit. A switch allows the user to select 3.3 V or 5 V RF powering.

UM2358 Rev 4

UM2358 Quick start

3.2

The motherboard and the daughter board must be connected together.

The jumper configuration when the kit is delivered is the default one.

The ST25R3916-DISCO kit is powered (like a PC) by the micro USB bus via a cable connected to the power source.

The unit must be supplied by a safety extra low voltage (SELV) limited power source through the USB port, the source must not exceed 60 V

DC

/ 8A / 100VA

When powered up, the microcontroller starts the firmware, which is already downloaded in the Flash memory.

This makes it possible to demonstrate the different capabilities of the ST25R3916.

• Reader and writer

• Card emulation

• Peer to peer

• Automatic antenna tuning

• USB mode (see

Section 3.2

)

There is no need for modifications or configurations to run the demonstration. Refer to the firmware’s user manual available on STMicroelectronics website to get more details.

Getting started with USB mode

Connect the discovery kit to a PC using a micro USB cable. The USB port of the PC must be capable of delivering at least 250 mA at 5 Volt.

To control the board, download the software from the dedicated page on www.st.com

and install it. Further information on how to operate the software and the GUI that can be used to control the control the board can be found in UM2511 “ST25R3916-DISCO kit user manual”, available on www.st.com

.

• Micro USB cable

• USB port, capable of delivering at least 250 mA at 5 V (1.25 W)

• Unit must be supplied by a safety extra low voltage (SELV) limited power source through the USB port

• For embedded ST link and STM32 Nucleo ecosystem development usage a mini USB cable is required

MB1396 hardware UM2358

The PCB (printed circuit board) of the motherboard is usually connected via USB to the PC.

The embedded firmware controls the STM32 MCU that operates the ST25R3916 via the extension connectors.

Both boards are powered by the 5 V supply of the USB bus. An LDO converts this voltage down to 3.3 V to supply the microcontroller and the ST25R3916. The extension board is provided with both 3.3 and 5 V supplies, it is possible to select one of them.

A green LED close to the motherboard micro USB plug indicates when the board is powered.

5.1 ST25R3916

The ST25R3916 is directly connected to the filtered 5 V USB supply. There are additional supply filtering components placed close to the NFC/HF reader IC.

During layout all decoupling capacitors have been placed as close as possible to the

ST25R3916 chip.

To demonstrate the capacitive wake-up feature, two capacitive sensing electrodes are placed on the PCB.

For SPI cross-connecting another reader PCB, serial resistors can be removed and CN100 used.

By default, the SPI is the firmware and hardware access bus. The I2C bus can be used instead by changing J200, J201, J202, J203, J204 and J205.

J206 makes it possible to bypass the internal V
