Product details

Overview

ST25DV16KC-IE6S3 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), 256-byte fast-transfer buffer, energy harvesting output (V_E_H), and configurable GPO interrupt. It operates from 1.8–5.5 V and supports 1 MHz I²C, NFC Forum Type 5 certification, and field-powered operation in industrial sensor tagging and smart packaging.

For engineers reviewing the ST25DV16KC-IE6S3 datasheet, ST25DV16KC-IE6S3 pinout, ST25DV16KC-IE6S3 application, or ST25DV16KC-IE6S3 equivalent, key selection criteria include RF/I²C dual-interface coordination, 40-year data retention, password-protected memory segmentation, GPO event configuration (field change, write completion), and package-specific LPD/VDCG support for low-power modes.

Technical Context

The ST25DV16KC implements a dual-domain architecture: an I²C interface handles byte-level EEPROM access and system configuration, while the RF interface complies fully with ISO/IEC 15693 for block-level (4-byte) contactless reads/writes at up to 53 Kbit/s. Its internal 28.5 pF tuning capacitance enables direct antenna coil connection without external matching components.

Fast transfer mode uses a dedicated 256-byte volatile buffer to shuttle data between I²C and RF domains without host intervention; energy harvesting delivers unregulated analog voltage (V_E_H) during RF field presence; GPO supports both open-drain (SO8/TSSOP8/UFDFPN8) and CMOS (WLCSP10/UFDFPN12) outputs with programmable event triggering including RF activity, memory write completion, and mailbox status.

Key Specifications

Pinout & Package

ST25DV16KC-IE6S3 is supplied in UFDFPN8 package (8-pin, 2 × 2 mm, ECOPACK2 RoHS-compliant), featuring open-drain GPO and no LPD/VDCG pins. This variant supports full I²C and RF functionality with minimal footprint for space-constrained PCBs.

Pin/Terminal	Circuit Role	Design Meaning
V_E_H	Energy harvesting analog output	Delivers unregulated RF-derived voltage to power external low-power peripherals; high-Z when field absent or harvesting disabled.
AC0 / AC1	RF antenna coil terminals	Differential inputs for connecting resonant LC tank; internal 28.5 pF tuning capacitance eliminates need for external trim caps.
V_SS	Ground reference	Common return for V_CC, V_E_H, and RF analog front-end; must be low-impedance for stable RF performance.
V_CC	DC supply input	Accepts 1.8–5.5 V; powers internal regulator and I²C logic; isolated from RF rectified 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.
SCL	I²C serial clock input	Master-generated clock strobe; requires external pull-up; supports standard/fast-mode plus 1 MHz high-speed mode.
SDA	I²C bidirectional data line	Open-drain I/O shared across multiple devices; requires external pull-up; handles address recognition and byte transfers.

Key Features

Feature	Design Value
Configurable memory protection	Four user areas with independent 64-bit RF/I²C passwords - enables secure partitioning of calibration data, firmware, and user settings.
Fast transfer mode buffer	256-byte volatile mailbox - decouples RF and I²C timing, allowing background data sync without host polling or latency stalls.
NFC Forum Type 5 certification	Full compliance with NFC Forum specifications - guarantees out-of-box reader compatibility for mobile and industrial NFC infrastructure.
Multi-event GPO configuration	Single pin reports RF field change, memory write completion, or fast-transfer readiness - reduces GPIO count and simplifies host wake-up logic.
Integrated RF tuning capacitance	28.5 pF internal capacitor - eliminates external matching network, reducing BOM cost and layout sensitivity for antenna design.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ST25DV04KC-IE6T3	4-Kbit EEPROM (512 bytes I²C / 128 blocks RF), same pinout and feature set	Limited memory depth for complex calibration or multi-sensor data logging	Select when cost sensitivity outweighs memory requirement and full 16-Kbit capacity is unused.
ST25DV64KC-IE6T3	64-Kbit EEPROM (8192 bytes I²C / 2048 blocks RF), identical architecture and package options	Higher density supports firmware image storage or extended audit trails but increases unit cost	Choose for future-proofing or applications requiring >2 KB of persistent, dual-interface data storage.

Compared with ST25DV04KC-IE6T3, ST25DV16KC-IE6S3 provides 4× more EEPROM for richer device metadata without changing board layout; versus ST25DV64KC-IE6T3, it offers optimal balance of memory headroom and cost for mid-tier industrial tagging and authentication use cases.

FAQ

What is the maximum RF data rate supported by ST25DV16KC-IE6S3?

The ST25DV16KC-IE6S3 supports a custom fast read access mode up to 53 Kbit/s per ISO/IEC 15693, exceeding standard 26.48 Kbit/s high-data-rate mode. This is achieved through optimized command sequencing and internal buffering, enabling rapid retrieval of multi-block payloads during NFC reader interrogation without protocol extension.

How does the energy harvesting function operate, and what load can it drive?

V_E_H delivers unregulated analog voltage derived from the RF carrier field, active only when sufficient field strength is present and energy harvesting is enabled via configuration register. It is not current-limited or regulated; typical output ranges from 1.2 V to 3.3 V depending on field strength and antenna coupling, and is rated for ≤1 mA continuous load - sufficient for biasing low-power comparators or enabling wake-up logic in companion ICs.

Can the GPO pin be used to wake up a microcontroller from deep sleep?

Yes - the GPO pin can be configured to assert a pulse or level change on RF field detection, memory write completion, or fast-transfer buffer readiness. When connected to a microcontroller's external interrupt pin with appropriate pull-up, it reliably triggers wake-up from STOP or standby modes, eliminating the need for periodic polling and reducing system power consumption in battery-operated designs.

Is the 64-bit UID factory-programmed and guaranteed unique across all ST25DV16KC units?

Yes - each ST25DV16KC-IE6S3 device contains a globally unique 64-bit UID programmed during wafer sort and verified per ISO/IEC 15693. The UID is stored in a read-only system configuration block and cannot be altered; it serves as the primary identifier during anticollision inventory and is traceable to ST's manufacturing lot and die position for full supply-chain accountability.
