Product details

Overview

ST25DV04KC-JF6D3 from STMicroelectronics is a dynamic NFC/RFID tag IC with 4-Kbit EEPROM, dual I²C and ISO/IEC 15693 contactless interfaces, 1.8–5.5 V supply, 256-byte fast-transfer buffer, and energy harvesting output (V_EH). It operates as a secure, field-powered memory node in smart labels, asset tags, and industrial IoT sensors where wired configuration and wireless read/write coexist.

For engineers reviewing the ST25DV04KC-JF6D3 datasheet, ST25DV04KC-JF6D3 pinout, ST25DV04KC-JF6D3 application, or ST25DV04KC-JF6D3 equivalent, key selection criteria include I²C-to-RF mailbox latency, RF write endurance at 105 °C, configurable password-protected memory areas, and GPO event triggering for host wake-up - all validated in DS13519 Rev 8.

Technical Context

This device implements a dual-interface architecture: the I²C interface accesses 512 bytes of EEPROM as byte-addressable memory, while the RF interface accesses the same storage as 128 blocks of 4 bytes each, compliant with ISO/IEC 15693 and NFC Forum Type 5. Internal tuning capacitance is fixed at 28.5 pF for antenna matching.

It features a dedicated 256-byte volatile buffer enabling fast transfer mode between interfaces, with GPO interrupt support for RF field change, memory write completion, and mailbox activity. The LPD pin enables sub-1 μA standby in 10-ball and 12-pin packages - not present in the 8-pin SO8/TSSOP8/UFDFPN8 variants like JF6D3.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory capacity	4-Kbit (512 bytes) EEPROM, organized as 128 RF blocks × 4 bytes or 512 I²C byte addresses
I²C interface speed	Up to 1 MHz - supports high-speed configuration without bus arbitration delays
RF data rate	Up to 53 Kbit/s fast read - enables rapid tag interrogation in logistics scanning
Write endurance	1 million cycles at 25 °C; 600k at 85 °C - validated for repeated firmware patching in field-deployed devices
Data retention	40 years at 25 °C - ensures long-term calibration or serial number storage in medical devices
Supply voltage range	1.8 V to 5.5 V - interoperable with 3.3 V microcontrollers and legacy 5 V systems
Energy harvesting output	V_EH analog pin delivers unregulated RF-derived voltage - powers low-current external comparators or wake-up circuits

Pinout & Package

ST25DV04KC-JF6D3 is supplied in an 8-pin SO8N package (ECOPACK2, RoHS-compliant), featuring open-drain GPO output and no LPD or VDCG pins. Pin functions are electrically defined and mechanically fixed per DS13519 Figure 2.

Pin/Terminal	Circuit Role	Design Meaning
V_EH	Energy harvesting analog output	Unregulated voltage source powered by RF field - requires external RC filter for stable biasing of ultra-low-power peripherals
AC0 / AC1	RF antenna coil terminals	Differential inputs for 13.56 MHz LC tank - must be matched to 28.5 pF internal capacitance for optimal power transfer
V_SS	Ground reference	Common return for V_CC, V_EH, and RF analog circuitry - requires low-inductance connection to minimize noise coupling
V_CC	DC supply input	1.8–5.5 V wired power source - powers I²C logic and internal regulator; isolates RF rectified supply from V_CC pin
GPO	Configurable open-drain interrupt output	Signals RF field presence, memory write completion, or mailbox status - requires external pull-up ≥4.7 kΩ
SCL	I²C clock input	Master-generated clock strobe - open-drain compatible; pull-up required to V_CC
SDA	I²C bidirectional data line	Open-drain I/O shared across multiple devices - pull-up required to V_CC; supports multi-master arbitration

Key Features

Feature	Design Value
ISO/IEC 15693 & NFC Forum Type 5 compliance	Fully certified interoperability with standard NFC readers - eliminates protocol validation effort in consumer electronics integration
Four configurable password-protected memory areas	Enables segmented access control: e.g., Area 1 for calibration data (read-only RF), Area 2 for logs (I²C-write-only), Area 3 for user config (dual-interface R/W)
256-byte fast-transfer buffer (mailbox)	Eliminates I²C-RF handshaking overhead - allows burst transfers of sensor metadata from MCU to NFC reader in <10 ms
RF-triggered GPO events	Wakes host MCU on field detection or memory write - reduces system-level polling power by >90% in battery-powered trackers
Internal 28.5 pF tuning capacitance	Reduces external BOM count - only antenna coil and optional trim capacitor needed for full ISO 15693 compliance

Applications

Smart Industrial Labels

Medical Device Calibration Tags

Use Scenario: Reusable metal-mount label on CNC tooling stores calibration offsets, usage counters, and maintenance history.

IC Role / Device Role / Timing Role: Dual-interface EEPROM node: I²C updates calibration via PLC during setup; NFC reads data during tool change.

Use Value: Eliminates manual data entry errors and enables traceable, tamper-evident calibration records with password-protected write zones.

Use Scenario: Sterilizable tag on surgical instrument housing stores sterilization cycle count, last calibration date, and firmware version.

IC Role / Device Role / Timing Role: Secure memory hub: I²C writes after calibration; NFC reads during pre-op check without opening sealed packaging.

Use Value: Supports UDI compliance with 40-year data retention and RF write endurance up to 105 °C - survives repeated autoclaving.

Asset Tracking Beacons

IoT Sensor Node Configuration

Use Scenario: Tamper-resistant tag on shipping container logs GPS coordinates, temperature excursions, and door-open events via connected MCU.

IC Role / Device Role / Timing Role: Field-powered data sink: RF writes event timestamps from MCU's GPO-triggered interrupts; I²C reads full log during depot download.

Use Value: Enables offline logging with zero-battery design - energy harvesting powers MCU wake-up and timestamp writes during RF interrogation.

Use Scenario: Configurable sensor node in HVAC duct monitors airflow, humidity, and particulate levels; settings updated via NFC during commissioning.

IC Role / Device Role / Timing Role: Configuration bridge: I²C loads sensor thresholds from MCU; NFC reads/writes parameters without disassembly or wiring.

Use Value: Reduces field service time by 70% - technicians adjust setpoints using smartphones instead of laptop + USB adapter.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dynamic NFC tag applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP NT3H2111W0FHKH	2-Kbit EEPROM, no energy harvesting output, integrated 13.56 MHz oscillator for active mode	Lacks V_EH pin and fast-transfer buffer - unsuitable for MCU wake-up or burst sensor data transfer	Select when compact size and lower cost outweigh need for energy harvesting or high-speed I²C-RF sync
ON Semiconductor N24RF04	4-Kbit EEPROM, I²C-only interface, no RF capability, 1.7–5.5 V supply	No contactless functionality - cannot serve as NFC-readable tag or field-powered node	Select only for pure wired EEPROM replacement where NFC is unnecessary

Compared with NT3H2111W0FHKH and N24RF04, ST25DV04KC-JF6D3 uniquely combines 4-Kbit dual-interface memory, energy harvesting, and 256-byte mailbox - making it the sole choice for battery-free, high-throughput NFC-configurable edge nodes.

FAQ

What is the maximum RF data rate supported by ST25DV04KC-JF6D3?

The device supports a custom fast read access mode up to 53 Kbit/s, verified per DS13519 Rev 8 Section 1.1. This exceeds standard ISO/IEC 15693 high-data-rate mode (26.48 Kbit/s) and enables rapid inventory scans in high-throughput logistics environments.

Does ST25DV04KC-JF6D3 support password protection for individual memory areas?

Yes - it provides three 64-bit RF passwords and one 64-bit I²C password, allowing independent read/write protection for up to four user memory areas. Area boundaries are configured via ENDA registers in the system configuration area, with granularity of 8 RF blocks (32 bytes).

Can the GPO pin be used to wake up an external microcontroller?

Yes - the GPO pin is configurable to assert on RF field detection, memory write completion, or fast-transfer buffer activity. In SO8N package (JF6D3), it is open-drain and requires an external pull-up; it drives a logic-high signal to wake a host MCU's external interrupt pin.

Is energy harvesting output regulated, and what load can it drive?

No - V_EH is an unregulated analog output derived from the RF field. Per DS13519 Section 2.5, it enters high-Z state when RF field strength is insufficient. It can drive ultra-low-power circuits (e.g., comparators, reset ICs) drawing ≤10 µA; external regulation is required for higher loads.
