Product details

Overview

EVAL-ST95HF from STMicroelectronics is an evaluation kit for the ST95HF 13.56 MHz NFC transceiver, enabling rapid prototyping of dual-mode NFC systems (reader and card emulation) compliant with ISO/IEC 14443A/B, 15693, and 18092 standards. It integrates STM32F103RGT6 MCU (ARM Cortex-M3, 1 MB Flash), a 47 mm × 34 mm four-turn PCB antenna, color LCD (320×200), five-color status LEDs, joystick interface, and mini-USB power/debug connectivity.

For engineers reviewing the EVAL-ST95HF datasheet, EVAL-ST95HF pinout, EVAL-ST95HF application, or EVAL-ST95HF equivalent, this kit delivers validated hardware-software reference design for NFC tag emulation, peer-to-peer NDEF exchange (URI/VCARD/URL), and multi-protocol reader deployment - all with on-board SPI interconnect, JTAG debug support, and production-ready antenna tuning circuitry.

Technical Context

The EVAL-ST95HF implements a complete NFC system architecture centered on the ST95HF transceiver, which operates in two mutually exclusive modes selected via on-screen menu: ISO/IEC 14443A-compliant card emulation (NFC Forum Type 1–4 tag support) and full multi-protocol reader mode (including ISO/IEC 14443B, 15693, and 18092). Communication between ST95HF and STM32F103RGT6 occurs over a dedicated SPI bus with hardware CS control.

Power is supplied exclusively via USB 5 V, regulated locally to 3.3 V for digital logic and analog RF sections; the etched antenna features integrated matching network components (capacitors and inductors) optimized for 13.56 MHz operation without external tuning tools. Firmware execution resides in the STM32's internal Flash memory, with JTAG access enabled for real-time debugging and firmware updates.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, analog ICs, power devices, sensors, and wireless solutions for industrial, automotive, and consumer applications.

The EVAL-ST95HF belongs to ST's NFC evaluation platform family, engineered to accelerate time-to-proof-of-concept for dual-mode NFC applications - specifically targeting interoperability validation, NDEF message exchange, and antenna performance benchmarking in real-world RF environments.

FAQ

Does EVAL-ST95HF support NFC peer-to-peer (P2P) mode?

Yes. The ST95HF transceiver on the board fully supports ISO/IEC 18092 (NFCIP-1) for P2P communication. Two EVAL-ST95HF boards can operate face-to-face in P2P mode to exchange NDEF messages such as URIs, vCards, or URLs - with mode selection handled via the on-screen menu and joystick interface.

Can the onboard antenna be replaced or extended?

No. The 47 mm × 34 mm, four-turn etched antenna is integral to the PCB layout and tuned with fixed matching components. ST does not provide mechanical or electrical provisions for antenna replacement or extension; modifications would invalidate RF performance and compliance with NFC Forum specifications.

What software tools are required to develop firmware for EVAL-ST95HF?

Development requires STM32 Standard Peripheral Library or HAL drivers, STM32CubeMX for initialization code generation, and ARM GCC or Keil MDK-ARM toolchain. ST provides the STM32-EVAL-ST95HF application firmware source code and documentation downloadable from www.st.com under DocID026572.

Is USB CDC (Virtual COM Port) functionality available out-of-the-box?

Yes. The STM32F103RGT6 firmware preloaded on the board implements USB CDC class, enabling serial communication over the mini-USB connection. This allows host PC applications to send/receive AT-style commands to the ST95HF transceiver and monitor status via standard terminal software without additional drivers on Windows, macOS, or Linux.
