Product details

Overview

ST25R3916-DISCO from STMicroelectronics is a ready-to-use evaluation kit comprising an STM32L476-based motherboard (MB1396) and an ST25R3916 HF NFC reader daughterboard (MB1414) with integrated PCB antenna and VHBR tuning circuit, supporting ISO 14443A/B, ISO 15693, FeliCa™, NFC-A/B/F/V, and EMVCo-compliant contactless transactions at 13.56 MHz.

For engineers reviewing the ST25R3916-DISCO datasheet, ST25R3916-DISCO pinout, ST25R3916-DISCO application, or ST25R3916-DISCO equivalent, this kit enables rapid validation of high-performance NFC reader functionality, host card emulation (NFC-F and NFC-A), automatic antenna tuning, capacitive/inductive tag presence detection, and SPI/I²C interface integration in secure payment, access control, and industrial ID systems.

Technical Context

The ST25R3916-DISCO integrates two hardware boards: MB1396 hosts an Arm® Cortex™-M4 MCU with ST-LINK debugger, 2.4" TFT touchscreen, USB power, and firmware-ready peripherals; MB1414 implements the ST25R3916 IC - a fully integrated 13.56 MHz NFC transceiver with 3.3 V operation, 10 Mb/s SPI, and 400 kbit/s / 1 Mb/s I²C interfaces.

It supports dual-mode operation (initiator and target), NFC Forum tag type emulation (Type 3 & Type 4A), stream mode for custom protocol extension, and low-power tag detection via both capacitive and inductive sensing - eliminating external wake-up circuitry in battery-powered applications.

FAQ

What hardware components are included in the ST25R3916-DISCO kit?

The kit contains two printed circuit boards: MB1396 (STM32L476-based motherboard with Arm® Cortex™-M4 CPU, ST-LINK debugger, 2.4" TFT touchscreen, LEDs, buttons, and dual USB connectors) and MB1414 (daughterboard embedding the ST25R3916 NFC transceiver IC, PCB antenna, and VHBR tuning circuit). No additional hardware is required for basic evaluation.

Does the ST25R3916-DISCO support host card emulation (HCE)?

Yes - the ST25R3916 IC on the MB1414 board natively supports NFC Forum Type 3 (FeliCa™-based) and Type 4A (ISO 14443A-based) host card emulation modes. Firmware examples and middleware for HCE are provided in the downloadable package from st.com, enabling secure element–free emulation in access control and transit ticketing use cases.

Can the ST25R3916-DISCO be used for EMVCo certification testing?

Yes - the ST25R3916-DISCO implements all mandatory physical layer and protocol features required by EMVCo Level 1 (physical/radio) and Level 2 (protocol) specifications for 13.56 MHz contactless readers, including field strength control, modulation depth compliance, timing accuracy, and anti-collision handling per ISO/IEC 14443.

What software and documentation are provided with the kit?

ST provides application notes, firmware source code, drivers, full schematics (PDF and Gerber), BOM, and PC software tools - all downloadable from www.st.com under document DB3799. The package includes ready-to-run examples for tag reading, peer-to-peer communication, HCE, and automatic antenna tuning calibration.
