STMicroelectronics ANT-1-6-ST25DV

Overview

ANT-1-6-ST25DV from STMicroelectronics is a dual-antenna reference evaluation kit for the ST25DV04K 4-Kbit dual-interface EEPROM, featuring two PCBs (45 mm × 75 mm and 18 mm × 24 mm) with 13.56 MHz single-layer inductive antennas, integrated I²C interface, and energy harvesting output (VOUT) with 10 nF filtering. It enables rapid prototyping of NFC-powered sensor tags and batteryless data logging systems.

For engineers reviewing the ANT-1-6-ST25DV datasheet, ANT-1-6-ST25DV pinout, ANT-1-6-ST25DV application, or ANT-1-6-ST25DV equivalent, this kit supports functional validation of RF coupling efficiency, I²C read/write timing under harvested power, and interoperability with CR95HF-A demo boards - critical for NFC-enabled industrial asset tagging and smart packaging design.

Technical Context

The kit implements two physical antenna variants optimized for different near-field coupling distances and form factors: C1 (larger, higher inductance) and C6 (compact, lower inductance), both tuned to 13.56 MHz per ISO/IEC 14443 Type A/B and ISO/IEC 15693 standards. Each board integrates the ST25DV04K IC with its dual-interface architecture - RF contactless interface compliant with ISO/IEC 15693 and wired I²C interface operating at up to 1 MHz.

Energy harvesting functionality delivers regulated VOUT from RF field coupling, supporting operation down to −15 dBm reader field strength. The 10 nF on-board capacitor stabilizes harvested voltage for low-power microcontroller wake-up or sensor biasing without external LDOs.

FAQ

What is the purpose of the two different antenna PCBs included in the kit?

The kit includes two distinct antenna layouts: ST25DV_Discovery_ANT_C1 (45 mm × 75 mm) optimized for longer-range coupling and higher RF power transfer, and ST25DV_Discovery_ANT_C6 (18 mm × 24 mm) designed for space-constrained applications with tighter field focus. Both are impedance-matched to the ST25DV04K's RF input and validated per ISO/IEC 15693 requirements.

Can the ANT-1-6-ST25DV operate without an external power source?

Yes - the board harvests energy directly from the 13.56 MHz RF field via its etched antenna and delivers it as regulated VOUT using the onboard 10 nF filter capacitor. This enables full read/write operation of the ST25DV04K EEPROM and can power small external logic circuits when paired with a compliant NFC reader.

Which software tools support configuration of the ST25DV04K through this kit?

The official ST Dual Interface EEPROM PC software - downloadable from www.st.com - supports full register configuration, RF parameter tuning, energy harvesting threshold setting, and I²C transaction monitoring. It communicates with the kit via the ST25Dx_DISCOVERY_MBOARD connector and requires no additional hardware beyond a USB cable.

Is FCC and Industry Canada certification included with the kit?

Yes - the ANT-1-6-ST25DV is pre-certified to FCC Part 15.105 Class B and Industry Canada RSS-210. Full compliance statements, test reports, and labeling guidance are provided in DocID029578 Rev 3, enabling immediate integration into commercial products targeting North American markets without additional regulatory retesting.
