ST25R3916B High Performance NFC Universal Device and Emvco Reader
Owner’s Manual
Introduction
The STEVAL25R3916B is a ready-to-use kit based on the ST25R3916B high-performance NFC universal device for contactless applications. The kit allows evaluating this device features and functionality in the reader/writer, peer to peer, and card emulation modes. The kit consists of:
- a microprocessor main board (STEVAL-M25R16B), which includes hardware and software tools that enable using the entire STM32 ecosystem. This board is powered through USB connectors
- a reader expansion board (STEVAL-D25R16B), which embeds the ST25R3916B device and an antenna etched on the PCB with its tuning circuit
The communication link between the two boards is the SPI bus. The processor card provides the power. Specific data lines complete the pin connector assignment shared between the cards.
Thanks to several demonstrations that can be performed, this kit helps the users develop and test their applications. The kit is FCC certified, with FCC ID: YCPR3916BD1. It is also IC certified, with IC: 8976A-R3916BD1; PMN: STEVAL-25R3916B; HVIN: STEVAL-25R3916B.

Hardware overview
The main board PCB is usually connected to the PC via USB.
The STM32 MCU firmware controls the ST25R3916B via the extension connectors.
The 5 V supply of the USB bus powers both boards. An LDO converts this voltage down to 3.3 V to supply the microcontroller and the ST25R3916B.
For the reader expansion board, you can select a 3.3 or 5 V RF powering. A green LED close to the motherboard micro-USB plug indicates when the board is powered.
2.1 Main board hardware
The STEVAL-25R3916B main board embeds a 32-bit microcontroller of the STM32L476 series, which is based on the Arm Cortex-M4 high-performance CPU with FPU. This board is powered through the USB bus. It includes:
- an ST-LINK in-circuit debugger and programmer for STM32 microcontrollers
- push buttons (reset and user)
- a mini-USB debug connector
- a user-dedicated micro-USB connector
- support for ST NFC tag

2.1.2 Software development configuration
This section describes the software development configuration for the main board. It also describes the USB connection when using the embedded ST-LINK.
The J1 micro-USB connector powers the STEVAL-25R3916B.
The J2 mini-USB allows exchanging data between the board and the computer.
2.2 Expansion board hardware
The STEVAL-25R3916B reader expansion board embeds:
- ST25R3916B
- an antenna, with its own tuning circuit, etched on the PCB
- a switch to select 3.3 V or 5 V RF powering
The ST25R3916B is directly connected to the filtered 5 V USB supply.
There are additional supply filtering components close to the NFC/HF reader IC. All the decoupling capacitors have been placed as close as possible to the ST25R3916B.
To connect another reader PCB via SPI, remove the serial resistors and use CN100. By default, the SPI is the firmware and hardware access bus.
Use the I²C bus, instead, by changing J200, J201, J202, J203, J204, and J205.
J206 allows bypassing the internal VDD_RF/VDD_AM regulators to supply an output current higher than 350 mA.

2.2.1 Antenna and matching network components
This board contains the matching network and the automatic antenna tuning capacitors based on varicap.
Getting started
3.1 System requirements
- A micro-USB cable
- A USB port capable of delivering at least 400 mA at 5 V (2 W)
- A safety extra-low voltage (SELV) limited power source to supply the unit through the USB port
- A mini-USB cable to use the embedded ST-LINK and the STM32 ecosystem development
3.2 How to use the kit in standalone mode
Step 1. Connect the STEVAL-25R3916B main board to the reader expansion board.
Important: It must be used on a clean and non-flammable surface.
Step 2. The kit is delivered with the default jumper configuration. Power it through the micro-USB via a cable connected to the power source.
Step 3. Supply the unit through a safety extra-low voltage (SELV) limited power source via the USB port.
The source must not exceed 60 VDC/8 A/100 V.
When powered up, the microcontroller starts the firmware, which is already downloaded in the flash memory. This allows demonstrating the ST25R3916B features:
– reader and writer
– card emulation
– peer to peer
– automatic antenna tuning
– USB mode (refer to the next section for further details)
3.3 How to use the kit in USB mode
Step 1. Connect the STEVAL-25R3916B kit to a PC via a micro-USB cable.
Important: It must be used on a clean and non-flammable surface.
The PC USB port must be capable of delivering at least 250 mA at 5 V.
Step 2. To control the board, download the STSW-ST25R010 software and install it.
