Product details
Overview
ST25TA16K-AB6G3 from STMicroelectronics is an NFC Forum Type 4 Tag IC embedding 16-Kbit EEPROM, compliant with ISO/IEC 14443 Type A at 106 Kbps, featuring 25 pF internal tuning capacitance, 7-byte UID, and 128-bit password protection. It operates passively from an NFC reader or smartphone RF field and supports NDEF data structure for secure, standardized tag applications in smart packaging and access control.
For engineers reviewing the ST25TA16K-AB6G3 datasheet, ST25TA16K-AB6G3 pinout, ST25TA16K-AB6G3 application, or ST25TA16K-AB6G3 equivalent, key selection criteria include NFC Forum Type 4 compliance, 246-byte single-command read/write capability, 200-year data retention, 1-million-cycle endurance, and dual 128-bit read/write password enforcement - all verified in production-grade ST documentation (DocID027786 Rev 4).
Technical Context
The ST25TA16K-AB6G3 implements a fully passive RF interface based on ISO/IEC 14443 Type A, with no external power supply required - energy harvesting exclusively from the 13.56 MHz magnetic field. Its digital unit executes NFC Forum Type 4 Tag protocol commands including NDEF Tag Application Select, ReadBinary, UpdateBinary, and ST-proprietary ExtendedReadBinary and EnablePermanentState.
Memory management follows strict NDEF file layout per NFC Forum specifications: a read-only Capability Container (CC) file defines maximum read/write lengths (246 bytes), NDEF file size (2 KB), and access rights; a user-writable NDEF file stores payload; and an ST-proprietary System file holds configuration metadata and delivery-state flags.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Standard | NFC Forum Type 4 Tag + ISO/IEC 14443 Type A - ensures interoperability with all certified NFC readers and smartphones. |
| Data Rate | 106 Kbps - fixed baseband rate defining timing constraints for command-response latency and throughput. |
| Memory Capacity | 16-Kbit (2-Kbyte) EEPROM - provides sufficient space for multi-record NDEF messages including URI, text, and smart poster records. |
| Data Retention | 200 years - validated EEPROM endurance under standard storage conditions, critical for long-lifecycle tagging. |
| Endurance | 1 million erase-write cycles - enables repeated reprogramming in dynamic use cases like event ticketing or logistics tracking. |
| UID Length | 7-byte unique identifier - guarantees globally unique device identity for inventory, anti-counterfeiting, and secure pairing. |
| Password Protection | 128-bit read + 128-bit write passwords - enforces cryptographic-grade access control per NDEF file, preventing unauthorized reads/writes. |
Pinout & Package
ST25TA16K-AB6G3 uses a wafer-level chip-scale package (WLCSP) with two antenna terminals only - no conventional pins. The device is designed for direct bonding to a printed antenna coil (AC0/AC1), eliminating PCB pads or solderable leads. It is not mounted via SMT or through-hole; integration requires flip-chip or conductive adhesive attachment to tuned loop antennas.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC0 / AC1 | Antenna coil connection | Differential RF input pair - connects directly to external printed loop antenna; internal 25 pF tuning capacitance reduces need for external matching components. |
Key Features
| Feature | Design Value |
|---|---|
| NDEF-compliant memory architecture | Predefined CC, NDEF, and System files enable plug-and-play integration with Android Beam, iOS CoreNFC, and NFC Forum-certified middleware. |
| Single-command 246-byte I/O | Reduces transaction count and air-time overhead - improves read/write speed and battery efficiency in mobile readers. |
| Permanent lock capability | EnablePermanentState command makes NDEF file permanently read-only or write-locked - prevents post-deployment tampering in warranty seals or calibration tags. |
| ST-proprietary command set | ExtendedReadBinary, UpdateFileType, and EnablePermanentState extend base NFC Forum functionality for industrial configuration control. |
| Delivery-state flag in System file | Indicates factory-programmed vs user-modified state - supports traceability and supply-chain verification in OEM manufacturing flows. |
Applications
| Smart Packaging Authentication | Industrial Equipment Tagging |
|---|---|
|
Use Scenario: Embedded in pharmaceutical blister packs or luxury goods labels to verify authenticity via smartphone scan. IC Role / Device Role / Timing Role: Passive NFC tag IC storing cryptographically signed NDEF records; responds within <10 ms after RF field activation. Use Value: 7-byte UID + 128-bit password prevents cloning; 200-year data retention ensures validity across product shelf life. |
Use Scenario: Mounted on CNC machine panels or HVAC controllers to store firmware version, calibration data, and service history. IC Role / Device Role / Timing Role: Field-service-accessible memory node; supports 246-byte writes for full log entries without fragmentation. Use Value: Permanent lock capability secures calibration parameters against accidental overwrite during maintenance. |
| Access Control Credentials | Reusable Logistics Labels |
|
Use Scenario: Integrated into employee ID badges or door-access fobs for secure building entry using NDEF-based credential exchange. IC Role / Device Role / Timing Role: Secure credential carrier; leverages dual 128-bit passwords to separate read (authentication) and write (revocation) privileges. Use Value: 1-million-cycle endurance allows daily use over 27+ years; ISO/IEC 14443 Type A compatibility ensures reader interoperability. |
Use Scenario: Attached to returnable transport items (RTIs) for cycle tracking, cleaning status, and damage reporting across supply chain legs. IC Role / Device Role / Timing Role: Reconfigurable data hub; stores dynamic NDEF payloads updated at each depot using NFC-enabled handhelds. Use Value: Single 246-byte write command updates full cycle record atomically - avoids partial-write corruption in high-throughput environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC tag IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NT3H2111W0FHKH | 1-Kbyte EEPROM, integrated 13.56 MHz RF front-end with higher sensitivity; no internal tuning cap needed. | Better suited for low-field environments (e.g., metal-mounted tags); lacks permanent lock and delivery-state flag. | Select when antenna coupling is weak or space-constrained; avoid if permanent write-protection or factory-state tracking is required. |
| MF0ICU2 | 1-Kbyte EEPROM, MIFARE Ultralight C compliant; supports 48-bit password but no NDEF-native structure. | Requires custom NDEF wrapper implementation; lower security assurance than 128-bit AES-derived keys in ST25TA16K. | Choose for legacy MIFARE infrastructure compatibility; not recommended for new NFC Forum-certified designs requiring native NDEF support. |
Compared with NT3H2111W0FHKH and MF0ICU2, the ST25TA16K-AB6G3 uniquely combines NFC Forum Type 4 compliance, 2-Kbyte NDEF-native memory, permanent lock capability, and delivery-state visibility - making it optimal for high-integrity, standards-driven tagging where data structure fidelity and lifecycle control are mandatory.

FAQ
Does ST25TA16K-AB6G3 require an external power supply?
No. The ST25TA16K-AB6G3 is a fully passive device powered solely by the 13.56 MHz RF field from an NFC reader or smartphone. It contains no battery or VDD pin - energy harvesting occurs across AC0/AC1 antenna terminals, enabling maintenance-free operation in sealed or disposable applications.
How is memory access secured on ST25TA16K-AB6G3?
Memory access is secured via two independent 128-bit passwords - one for read operations and another for write operations - enforced at the protocol level. Passwords are verified before granting access to the NDEF file, and the EnablePermanentState command can irreversibly lock memory regions to prevent future modification.
What antenna design guidance applies to ST25TA16K-AB6G3?
The device integrates 25 pF internal tuning capacitance, simplifying antenna matching. Recommended antenna inductance is 1.0–1.5 µH with Q > 30 at 13.56 MHz. ST provides reference layouts (AN4914) and simulation models; impedance must be tuned to ~15–20 Ω resistive at resonance for optimal power transfer and communication range.
Can ST25TA16K-AB6G3 store multiple NDEF records?
Yes. The 2-Kbyte NDEF file supports multi-record NDEF messages per NFC Forum specification - including combinations of URI, Text, Smart Poster, and MIME-type records - with the NDEF Message Length field (first 2 bytes) dynamically indicating total payload size for proper parser handling.
