Product details
Overview
ST25DV16KC-JF8D3 from STMicroelectronics is a dynamic NFC/RFID tag IC with dual I²C and ISO/IEC 15693 contactless interfaces, 16-Kbit EEPROM (2048 bytes via I²C / 512 blocks × 4 bytes via RF), 1 MHz I²C support, 1.8–5.5 V supply, and integrated 28.5 pF tuning capacitance - deployed in smart labels, asset tracking tags, and industrial NFC-enabled sensors.
For engineers reviewing the ST25DV16KC-JF8D3 datasheet, ST25DV16KC-JF8D3 pinout, ST25DV16KC-JF8D3 application, or ST25DV16KC-JF8D3 equivalent, key selection criteria include RF/I²C fast transfer mode (256-byte mailbox), energy harvesting output (V_EH), configurable GPO interrupt behavior, and multi-level password protection across four user memory areas.
Technical Context
The device implements a dual-interface architecture: I²C handles byte-addressed EEPROM access and system configuration, while RF operates per ISO/IEC 15693 with full modulation/coding/subcarrier support and up to 53 Kbit/s custom fast read. The 256-byte volatile buffer enables synchronous data exchange between wired and contactless domains without host intervention.
Memory is partitioned into four user-configurable areas, each independently protected by 64-bit RF and I²C passwords; system registers control RF management (e.g., RF command interpreter enable/disable), GPO event mapping (field change, write completion, fast transfer), and low-power modes (LPD pin active only in WLCSP10/UFDFPN12 packages).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| I²C Speed | Up to 1 MHz - enables high-throughput configuration and firmware updates without bus contention in microcontroller-hosted systems. |
| RF Standard | ISO/IEC 15693 & NFC Forum Type 5 certified - ensures interoperability with standard NFC readers and mobile devices supporting Type 5 tag operations. |
| EEPROM Size | 16 Kbit (2048 bytes I²C / 512 blocks × 4 bytes RF) - supports extended sensor calibration data, device history logs, or secure credential storage in edge-tagged assets. |
| Write Endurance | 1 million cycles at 25 °C - guarantees reliable field-programmable parameter retention over multi-year deployments in industrial monitoring nodes. |
| Energy Harvesting | V_EH analog output - delivers unregulated RF-derived voltage to power external low-power circuitry (e.g., temperature sensor bias, wake-up comparator) without separate battery. |
| Operating Temp | –40 °C to 105 °C (UDFNP8/12) - maintains functional integrity in automotive under-hood or factory-floor environments where thermal cycling exceeds consumer-grade limits. |
| Tuning Capacitance | Integrated 28.5 pF - eliminates need for external matching capacitor in antenna design, reducing BOM count and PCB footprint in compact NFC tag layouts. |
Pinout & Package
ST25DV16KC-JF8D3 is supplied in an 8-pin SO8N package (ECOPACK2, RoHS compliant), featuring open-drain GPO output and no LPD/VDCG pins - optimized for cost-sensitive, space-constrained NFC label applications requiring minimal external components.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V_EH | Energy harvesting analog output | Delivers unregulated RF-derived voltage to power external low-power peripherals; high-Z when RF field is absent or insufficient. |
| AC0 / AC1 | Antenna coil connections | Differential RF interface inputs tuned to 13.56 MHz; must connect directly to external LC antenna without DC/AC coupling paths. |
| VSS | Ground reference | Common return for VCC, V_EH, and internal analog/digital blocks; requires low-impedance connection to minimize noise coupling into RF front-end. |
| VCC | DC supply input | Accepts 1.8–5.5 V; powers I²C interface and internal logic; internal regulator isolates VCC from rectified RF supply to prevent backfeed. |
| GPO | Configurable interrupt output | Open-drain output requiring external pull-up (>4.7 kΩ); signals RF field detection, memory write completion, or fast transfer events per register settings. |
| SDA | I²C bidirectional data line | Open-drain I/O; supports multi-master I²C bus sharing; requires external pull-up resistor to VCC for proper signal integrity. |
| SCL | I²C clock input | Input-only clock line; synchronizes all I²C transfers; must be driven by master with open-drain output and pull-up resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Fast Transfer Mode | 256-byte volatile mailbox enables zero-latency data handoff between I²C host and RF reader - critical for real-time sensor log synchronization in predictive maintenance tags. |
| Four-Region Memory Protection | User memory split into four independently password-protected areas (64-bit RF + 64-bit I²C per area) - allows tiered access control: e.g., public calibration data (Area 1), OEM firmware (Area 2), end-user config (Area 3), secure keys (Area 4). |
| NFC Forum Type 5 Certification | Guarantees compatibility with Android Beam, iOS Core NFC, and enterprise NFC infrastructure - eliminates interoperability validation effort in mobile-first IoT deployments. |
| Configurable GPO Events | GPO pin maps to 10+ RF/I²C events (field change, activity, write complete, fast transfer, pulse) - enables direct hardware wake-up of MCU or status LED without polling overhead. |
| Integrated Tuning Capacitance | 28.5 pF on-chip capacitance reduces external component count by one capacitor and improves antenna matching repeatability across manufacturing batches. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dynamic NFC tag applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NT3H2201W0FHKH | 1 Kbyte EEPROM, no energy harvesting, fixed 7-bit I²C address, no LPD/GPO flexibility | Limited to simple NFC data exchange (e.g., URL launch); lacks fast transfer buffer and multi-area protection | Select when cost is primary constraint and advanced security/energy features are unnecessary. |
| ST25DV04KC-JF8D3 | 4-Kbit EEPROM (512 bytes I²C), identical pinout and feature set except memory size and endurance (1M @25°C vs 600k @85°C) | Same use cases but constrained by smaller memory - suitable for basic ID tokens or firmware version stamps | Choose when memory demand is ≤512 bytes and thermal margin is <85°C. |
Compared with NT3H2201W0FHKH and ST25DV04KC-JF8D3, ST25DV16KC-JF8D3 provides 4× more EEPROM, energy harvesting capability, and full fast transfer mode - making it the only option among the three for battery-free sensor integration and multi-layer secure data partitioning.

FAQ
What is the maximum RF data rate supported by ST25DV16KC-JF8D3?
The device supports a custom fast read access mode up to 53 Kbit/s per ISO/IEC 15693 specifications, exceeding standard 26.48 Kbit/s high-data-rate mode. This is achieved through optimized subcarrier handling and reduced protocol overhead, enabling rapid bulk reads of sensor logs or firmware patches during NFC interrogation.
How does the 256-byte fast transfer buffer operate between I²C and RF interfaces?
The buffer acts as a volatile mailbox: I²C writes data to designated buffer addresses, then triggers a fast transfer command; the RF interface immediately reads that data as a contiguous block without EEPROM latency. No host polling is required - GPO asserts on completion, enabling deterministic handoff for time-critical applications like firmware updates.
Can the GPO pin be used to wake up a microcontroller from deep sleep?
Yes - GPO can be configured to assert on RF field detection or memory write completion. When wired to a GPIO interrupt pin with wake capability, it triggers MCU wake-up without continuous polling. For SO8N packages, an external pull-up resistor (>4.7 kΩ) is mandatory; CMOS GPO variants (WLCSP10/UFDFPN12) require VDCG supply for active-high assertion.
What is the role of the integrated 28.5 pF tuning capacitance?
This on-die capacitance forms part of the resonant LC tank with the external antenna coil, eliminating the need for a discrete capacitor. It improves impedance matching consistency across production units and simplifies antenna layout - particularly valuable in ultra-thin smart labels where component height and placement tolerance are critical.
