Product details

Overview

ST25DV04KC-JF8D3 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_E_H). It operates as a secure, field-powered memory node in smart labels, asset tags, and industrial IoT sensors where battery-free operation and host-controlled RF access are required.

For engineers reviewing the ST25DV04KC-JF8D3 datasheet, ST25DV04KC-JF8D3 pinout, ST25DV04KC-JF8D3 application, or ST25DV04KC-JF8D3 equivalent, key selection criteria include I²C-to-RF mailbox transfer latency, configurable GPO event triggering (field change, write completion), RF password-protected memory segmentation, and compatibility with NFC Forum Type 5 readers in industrial temperature ranges.

Technical Context

The device implements a dual-interface architecture: an I²C master-controlled serial interface for wired configuration and data loading, and an ISO/IEC 15693-compliant RF front end with analog tuning capacitance (28.5 pF) for coil matching. Its internal 256-byte volatile buffer enables deterministic fast transfer mode between interfaces without host polling.

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 via I²C), GPO behavior, and low-power modes. The GPO pin supports open-drain output (SO8/TSSOP8/UFDFPN8) or CMOS output (WLCSP10/UFDFPN12) with LPD-triggered standby current reduction to <1 µA.

Key Specifications

Pinout & Package

ST25DV04KC-JF8D3 is supplied in SO8N (8-pin narrow SOIC) package with exposed pad (EP), RoHS-compliant ECOPACK2. Pin functions are fixed per mechanical layout and match ST's standard SO8N footprint for drop-in PCB replacement.

Pin/Terminal	Circuit Role	Design Meaning
V_E_H	Energy harvesting analog output	Delivers unregulated RF-derived voltage to power external sensors or wake-up circuitry; high-Z when RF field is absent or insufficient
AC0 / AC1	RF antenna coil terminals	Differential inputs for external LC tank; require no DC bias; must be isolated from other signal paths
V_SS	Ground reference	Common return for V_CC, V_DCG, and V_E_H; decoupling capacitors must be placed adjacent to this pin
V_CC	DC supply input	Accepts 1.8–5.5 V; powers I²C interface and internal logic; internal regulator prevents backfeed from RF rectifier
GPO	Configurable interrupt output	Open-drain output; requires external pull-up (>4.7 kΩ); signals RF field presence, memory write completion, or fast-transfer readiness
SCL	I²C clock input	Master-generated clock; open-drain compatible; requires external pull-up; defines timing for all I²C transactions
SDA	I²C bidirectional data line	Open-drain I/O; shared across multiple I²C slaves; pull-up resistor mandatory for bus arbitration
EP	Exposed thermal pad	Must remain electrically floating; improves thermal dissipation but is not connected to internal ground or power

Key Features

Feature	Design Value
NFC Forum Type 5 certification	Guarantees interoperability with certified readers (e.g., smartphones, industrial scanners) without protocol stack customization
256-byte fast-transfer buffer	Eliminates host polling overhead by enabling atomic I²C-to-RF data handoff; critical for real-time sensor logging
Four independent memory protection areas	Enables tiered security: e.g., Area 1 for public calibration data (read-only), Area 3 for encrypted firmware (write-protected)
Configurable GPO events	Allows hardware-level wake-up of host MCU on RF field detection or memory write completion-reducing system power consumption
Energy harvesting output (V_E_H)	Provides up to ~2.5 V (typ.) from RF field-sufficient to power low-threshold comparators or RTCs in battery-free designs

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ST25DV16KC-JF8D3	16-Kbit EEPROM (2048 bytes), same pinout and feature set	Supports larger calibration tables or multi-sensor metadata storage	Select when >512 bytes of persistent, field-accessible data is required without changing PCB layout
NXH3670UK/N1E	16-Kbit NFC tag with integrated antenna matching network and 3.3 V LDO; no I²C interface	Designed for pure contactless use cases; lacks wired programming capability	Choose only if I²C host control and dual-interface flexibility are unnecessary and board space is constrained

Compared with ST25DV16KC-JF8D3, this part trades memory density for cost and footprint efficiency; compared with NXH3670UK/N1E, it adds design flexibility through I²C configurability and GPO-driven host coordination-but requires external antenna tuning and separate power routing.

FAQ

What is the maximum RF data rate supported by ST25DV04KC-JF8D3?

The device supports a custom fast read access mode up to 53 Kbit/s over ISO/IEC 15693, significantly exceeding the base 26.48 Kbit/s standard rate. This enables rapid inventory scanning in high-throughput logistics or tool-tracking applications where reader dwell time must be minimized. The rate is achieved using optimized subcarrier modulation and internal buffer handoff, not external controller intervention.

How does the GPO pin function in SO8N package variants?

In the SO8N package, GPO is an open-drain output requiring an external pull-up resistor (>4.7 kΩ) to V_CC. It can be configured to assert on RF field detection, memory write completion, or fast-transfer buffer readiness. Default behavior is RF field change detection, making it ideal for waking a host MCU from sleep upon NFC reader proximity-without continuous polling or additional GPIO resources.

Can ST25DV04KC-JF8D3 operate without a DC supply (V_CC)?

Yes-the device supports pure RF-powered operation. When V_CC is unconnected, the internal RF rectifier supplies power to the analog front end and EEPROM, enabling full ISO/IEC 15693 functionality including block reads/writes and UID transmission. However, I²C interface, GPO configuration, and fast-transfer buffer access require V_CC to be active.

What memory protection mechanisms are implemented?

The device provides layered protection: user memory is split into four configurable areas, each individually secured by up to three 64-bit RF passwords and one 64-bit I²C password. System configuration registers-including ENDA area limits and UID-are protected by a dedicated 64-bit configuration password. Passwords are stored in EEPROM and enforced at hardware level, preventing unauthorized read/write access regardless of interface used.
