Product details

Overview

ST25DV16KC-JF6D3 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 tags, and industrial IoT sensors for secure over-the-air configuration and energy harvesting.

For engineers reviewing the ST25DV16KC-JF6D3 datasheet, ST25DV16KC-JF6D3 pinout, ST25DV16KC-JF6D3 application, or ST25DV16KC-JF6D3 equivalent, key selection criteria include RF/I²C fast transfer mode (256-byte mailbox), configurable GPO interrupt behavior, multi-level password protection (three 64-bit RF + one 64-bit I²C user passwords), and low-power LPD control in WLCSP10/UFDFPN12 packages.

Technical Context

The ST25DV16KC-JF6D3 implements a dual-interface architecture where the I²C interface operates as a standard slave device (7-bit address, 1 MHz max) while the RF interface complies fully with ISO/IEC 15693-3 and NFC Forum Type 5 specifications - supporting all subcarrier modes (single/dual), data rates (26.48/52.96 kbit/s), and modulation schemes (ASK/PSK). Its analog front end includes an on-die 28.5 pF tuning capacitor to simplify antenna matching.

It features a dedicated 256-byte volatile buffer enabling fast bidirectional data exchange between I²C and RF domains without EEPROM wear; memory access is partitioned into four user-configurable areas with independent read/write protection, and system registers are secured by a separate 64-bit configuration password. The GPO pin supports mixed-event triggering (RF field change, memory write completion, fast transfer notification) and is implemented as open-drain in SO8/TSSOP8/UFDFPN8 packages.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory capacity	16 Kbit EEPROM = 2048 bytes (I²C) / 512 blocks × 4 bytes (RF)
I²C interface speed	Up to 1 MHz - enables high-speed wired configuration without bus contention
RF interface standard	ISO/IEC 15693 & NFC Forum Type 5 certified - ensures interoperability with commercial NFC readers
Write endurance	1 million cycles at 25 °C - sufficient for frequent firmware parameter updates in field-deployed devices

Supply voltage range	1.8 V to 5.5 V - compatible with both 3.3 V and 5 V microcontroller systems
Tuning capacitance	Integrated 28.5 pF - eliminates need for external matching capacitors in most antenna designs

Pinout & Package

ST25DV16KC-JF6D3 is packaged in UFDFPN8 (8-pin, 2 × 2 mm, ECOPACK2), featuring an open-drain GPO output and no LPD/VDCG pins - distinguishing it from WLCSP10 and UFDFPN12 variants. Pin functions are validated per DS13519 Rev 8 Figures 4 and 246.

Pin/Terminal	Circuit Role	Design Meaning
V_EH	Energy harvesting analog output	Delivers unregulated RF-derived voltage to power external low-current peripherals (e.g., temperature sensor bias)
AC0 / AC1	RF antenna coil terminals	Differential inputs for connecting series-tuned LC antenna; internal 28.5 pF capacitor reduces external component count
V_CC	DC supply input	Accepts 1.8–5.5 V; powers I²C interface and internal logic; internal regulator isolates RF and DC supplies
V_SS	Ground reference	Common return for V_CC, V_EH, and RF analog circuitry; must be low-impedance
SDA	I²C bidirectional data line	Open-drain I/O requiring external pull-up; supports multi-master arbitration and clock stretching
SCL	I²C clock input	Input-only; synchronizes all I²C transfers; requires external pull-up resistor
GPO	Configurable interrupt output	Open-drain output; signals RF field presence, memory write completion, or fast transfer events per register settings
EP	Exposed thermal pad	Must remain floating per datasheet - not connected to PCB ground or power planes

Key Features

Feature	Design Value
Fast transfer mode buffer	256-byte volatile mailbox enables zero-wear synchronization of I²C and RF data without EEPROM cycling
Multi-level password protection	Three 64-bit RF passwords + one 64-bit I²C password allow granular access control across four user memory areas
Energy harvesting output	V_EH pin delivers usable analog voltage under RF field - powers auxiliary sensors without separate battery
NFC Forum Type 5 certification	Guarantees out-of-box compatibility with Android/iOS NFC readers and enterprise RFID infrastructure
Configurable GPO interrupt	Single pin reports up to 7 RF/I²C events (e.g., field-on, write-complete, mailbox-ready) - reduces GPIO usage

Applications

Smart Industrial Labels

Secure Product Authentication

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-interface NFC tag applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ST25DV04KC-JF6D3	4-Kbit EEPROM (512 bytes / 128 blocks); identical pinout and feature set except memory size	Lower memory density suits simple ID/counter use cases; reduced cost for basic tagging	Select when application requires only UID + minimal metadata and cost sensitivity outweighs future scalability
ST25DV64KC-JF6D3	64-Kbit EEPROM (8192 bytes / 2048 blocks); same package options and protocol stack	Supports embedded firmware patches or multi-sensor logs; higher write latency per block due to larger array	Select when field-upgradable code or extended diagnostic history must reside on-tag without cloud dependency

Compared with ST25DV04KC-JF6D3 and ST25DV64KC-JF6D3, the ST25DV16KC-JF6D3 offers optimal balance: sufficient memory for firmware revision tracking and sensor calibration tables while maintaining fast 5 ms typical write time and full backward-compatible register mapping.

FAQ

Is ST25DV16KC-JF6D3 pin-compatible with ST25DV04KC-JF6D3 and ST25DV64KC-JF6D3?

Yes - all three variants share identical UFDFPN8 pinout, register map, and electrical characteristics; only memory size differs. This allows hardware reuse across product tiers, with firmware handling capacity detection via UID or system register reads. No layout changes are needed when scaling memory requirements.

How does the fast transfer mode reduce EEPROM wear during frequent I²C-to-RF data sync?

The 256-byte volatile buffer acts as a scratchpad: I²C writes populate the buffer, then a single RF write command commits the entire block to EEPROM. This avoids repeated byte-level RF writes - reducing 2048-byte sync from ~512 individual EEPROM writes (each consuming 1/1M endurance) to just one, extending effective lifetime by >500× for high-frequency updates.

What antenna design guidance applies given the integrated 28.5 pF tuning capacitance?

With 28.5 pF on-chip, external matching typically requires only a series inductor (L) and optional parallel capacitor (C) to resonate at 13.56 MHz. Recommended starting point: L = 1.0 µH, C = 0 pF; adjust L ±10% based on measured field strength. Antenna Q-factor should exceed 20 to ensure reliable energy harvesting at >5 cm read distance.

Can the GPO pin wake a host microcontroller from deep sleep using RF field detection?

Yes - GPO can be configured to assert on RF field presence (FIELD_CHANGE event). When wired to a GPIO with wake-on-change capability, it triggers MCU wake-up within 10 µs of field onset. No I²C activity is required; the RF analog front end autonomously drives GPO, enabling ultra-low-power listening modes with <1 µA standby current in compatible packages.
