Product details
Overview
ST25DV16KC-IE8T3 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 maintenance logs where secure, battery-free memory access is required.
For engineers reviewing the ST25DV16KC-IE8T3 datasheet, ST25DV16KC-IE8T3 pinout, ST25DV16KC-IE8T3 application, or ST25DV16KC-IE8T3 equivalent, key selection criteria include RF/I²C fast transfer mode (256-byte mailbox), configurable GPO interrupt behavior, energy harvesting analog output (V_EH), and multi-level password protection (three 64-bit RF user passwords + one I²C password).
Technical Context
The device implements a dual-interface architecture: I²C operates as a standard slave with addressable byte access and 5 ms typical write time per 1–16 bytes, while RF conforms fully to ISO/IEC 15693 and NFC Forum Type 5, supporting all subcarrier modes, data rates up to 53 Kbit/s, and block-level (4-byte) read/write with extended command support.
Its internal 256-byte volatile buffer enables fast transfer mode between interfaces, decoupling RF and I²C operations; system configuration is stored in protected EEPROM with UID, AFI, DSFID, and five 64-bit password registers - all accessible only after successful password authentication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory capacity | 16 Kbit EEPROM = 2048 bytes (I²C) / 512 blocks × 4 bytes (RF); supports split into four configurable, password-protected user areas |
| I²C interface | Two-wire, 1 MHz max clock rate; open-drain SDA/SCL; supports multiple-byte programming up to 256 bytes per transaction |
| RF interface | ISO/IEC 15693 & NFC Forum Type 5 compliant; supports all modulations, coding, subcarriers, and data rates; custom fast read up to 53 Kbit/s |
| Supply voltage | 1.8 V to 5.5 V DC on VCC; internal regulator isolates VCC from rectified RF supply; V_EH provides unregulated analog energy harvesting output |
| Operating temperature | –40 °C to 105 °C (Range 8); RF interface rated to 105 °C in UDFPN8/UFDFPN12 packages; full functionality at 125 °C supported only in SO8N/TSSOP8 |

| Package | UFDFPN8 (8-pin, exposed pad); RoHS-compliant ECOPACK2; open-drain GPO; no LPD/VDCG pins - low-power mode not available |
Pinout & Package
ST25DV16KC-IE8T3 is supplied in an 8-pin UFDFPN8 package (ECOPACK2, RoHS-compliant), featuring an exposed pad (EP) left floating. It implements open-drain GPO output and lacks LPD/VDCG pins - thus low-power down mode is not supported in this variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V_EH | Energy harvesting analog output | Delivers unregulated RF-derived analog voltage when field strength is sufficient; high-Z when disabled or field weak |
| AC0 / AC1 | RF antenna coil terminals | Differential inputs for external LC tank; must be isolated from all other DC/AC paths; internal 28.5 pF tuning capacitance |
| VSS | Ground reference | Common return for VCC, V_EH, and internal analog/digital circuits; requires local 10 nF + 100 nF decoupling |
| VCC | DC supply input | 1.8–5.5 V power source; internal regulator prevents backfeed from RF rectifier; boot sequence requires stable VCC before I²C access |
| GPO | Configurable interrupt output | Open-drain output; requires external pull-up (>4.7 kΩ); signals RF field change, memory write completion, or fast transfer events |
| SCL | I²C serial clock input | Strobes I²C data; open-drain compatible; pull-up resistor required to VCC; supports 1 MHz protocol timing |
| SDA | I²C serial data bidirectional | Open-drain I/O; wire-OR capable; pull-up resistor required to VCC; handles byte-addressed EEPROM reads/writes |
Key Features
| Feature | Design Value |
|---|---|
| Fast transfer mode | 256-byte volatile mailbox buffer enables synchronous data exchange between I²C and RF interfaces without host intervention |
| Multi-layer password security | Three independent 64-bit RF user passwords + one 64-bit I²C password + one 64-bit system configuration password - each protecting distinct memory areas |
| Energy harvesting output | V_EH pin delivers usable analog voltage from RF field for powering external sensors or logic - eliminates need for local battery in passive tag designs |
| NFC Forum Type 5 certification | Fully certified interoperability with NFC smartphones and readers; guarantees compliance with NFC Data Exchange Format (NDEF) message handling |
| Configurable GPO interrupt | GPO pin can be programmed to signal RF field presence, memory write completion, or fast transfer status - enabling wake-on-event for ultra-low-power systems |

FAQ
What is the maximum RF data rate supported by ST25DV16KC-IE8T3?
The device supports custom fast read access up to 53 Kbit/s per ISO/IEC 15693, achieved using high-speed modulation and optimized command sequencing. This rate applies to single/multiple block reads and is independent of I²C speed. Standard ISO/IEC 15693 data rates (e.g., 26.48 Kbit/s) are also fully supported for backward compatibility with legacy readers.
Can the GPO pin be used to wake up a microcontroller from deep sleep?
Yes - the GPO pin is configurable to assert on RF field detection, memory write completion, or fast transfer events. When set to "field change" mode (default), it outputs a pulse or level change upon RF field activation, enabling direct wake-up of an MCU's external interrupt pin without active polling. No additional components are needed beyond the required pull-up resistor.
How does energy harvesting work on ST25DV16KC-IE8T3, and what load can V_EH drive?
V_EH delivers unregulated analog voltage derived from the RF carrier field; its output depends on field strength, antenna coupling, and coil Q-factor. It operates in high-Z state when disabled or under insufficient field. While not designed to power digital ICs directly, it can drive low-current analog sensors (e.g., temperature or humidity ICs drawing <10 µA) or bias comparators in passive sensing nodes.
Is the UID programmable, or is it factory-fixed?
The 64-bit UID is factory-programmed by STMicroelectronics during wafer test and is permanently stored in the system configuration area. It complies with ISO/IEC 15693 and is used in anticollision inventory sequences. Users cannot modify the UID, but may configure AFI and DSFID registers to classify device families or storage types within their system architecture.
