STMicroelectronics ST25DV64KC-DISCO

Overview

ST25DV64KC-DISCO from STMicroelectronics is a demonstration kit for evaluating the ST25DV64KC dynamic NFC/RFID tag IC, featuring an STM32F476VGT6 microcontroller (LQFP100, 1 MB Flash, 192+4 KB SRAM), color LCD (320×200), touch driver, and dual antenna boards (50×40 mm and 25×20 mm, 13.56 MHz) with integrated ST25DV64KC tags.

For engineers reviewing the ST25DV64KC-DISCO datasheet, ST25DV64KC-DISCO pinout, ST25DV64KC-DISCO application, or ST25DV64KC-DISCO equivalent, this kit enables rapid validation of I2C-controlled NFC tag operation, energy harvesting (VOUT), GPO configuration, ISO/IEC 15693/NFC Forum Type 5 interoperability, and embedded firmware-driven use-case execution.

Technical Context

The kit implements a three-board architecture: a motherboard with STM32F476VG hosting firmware that drives two daughterboards - one with Class 3 antenna and one with Class 6 antenna - each embedding an ST25DV64KC tag IC. The ST25DV64KC operates in dual-interface mode: I2C slave (standard two-wire interface) and contactless RF (ISO/IEC 15693 compliant, NFC Forum Type 5).

Power is supplied via USB (micro or mini); onboard ST-LINK enables firmware update and debug. Energy harvesting output (VOUT) delivers harvested RF power through a 10 nF filter, and the GPO is software-configurable for event signaling. All demonstration use cases are pre-stored in the STM32's Flash memory.

FAQ

What interfaces does the ST25DV64KC device on this kit support?

The ST25DV64KC IC supports dual interfaces: an I2C slave interface (two-wire, bidirectional SDA/SCL) for host MCU control, and a contactless RF interface compliant with ISO/IEC 15693 and NFC Forum Type 5 standards for reader and smartphone interaction. Both interfaces access the same 64 Kbit EEPROM concurrently.

Does the kit include firmware and source code?

Yes - the STM32F476VG motherboard ships with preloaded demonstration firmware stored in Flash memory. Full schematics, BOM, Gerber files, drivers, and firmware source code are publicly available for download from www.st.com under the ST25DV64KC-DISCO product page.

Can the energy harvesting output (VOUT) power external circuitry?

The VOUT pin delivers harvested RF energy filtered by a 10 nF capacitor, intended for low-power auxiliary functions such as wake-up signaling or biasing simple sensors. It is not rated for continuous load driving; maximum output depends on field strength and antenna coupling, and no voltage regulation is provided.

How is debugging and firmware update performed?

Debugging and firmware updates are performed via the onboard ST-LINK debugger, accessible through the ST-LINK mini-USB connector. The ST-LINK supports SWD protocol, enabling real-time debugging, flash programming, and register inspection without requiring external tools.
