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:

• MB1

396 (ST25_Discovery_Mboard): a micropro

cessor 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

ovides the power. Specific data lines complete the pin connector assignment shared

between cards.

A variety of demonstrations can be performed with this kit, w

hich allows the users to

develop and test their applications.

The MB1396 and the MB1414 boards schematics, BOM, Gerber files, drivers and firmware

e available on the STMicroelectronics website www.st.com.

Description 2 UM2358 Description 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.

UM2358 Quick start 3 Quick start 3.1 Getting started in standalone mode 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.

MB1396 hardware 4 UM2358 MB1396 hardware 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.

MB1414 hardware 5 MB1414 hardware 5.1 ST25R3916 UM2358 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.
