Product details
Overview
ST25TV16K-AP6G3 from STMicroelectronics is an NFC Forum Type 5 contactless RFID tag IC with 16 Kbit EEPROM, ISO/IEC 15693-compliant RF interface, 28.5 pF internal tuning capacitance, and hardware-based kill capability for privacy protection. It operates across –40 to +85 °C and delivers up to 53 Kbit/s fast read access in smart label, asset tagging, and secure product authentication systems.
For engineers reviewing the ST25TV16K-AP6G3 datasheet, ST25TV16K-AP6G3 pinout, ST25TV16K-AP6G3 application, or ST25TV16K-AP6G3 equivalent, key selection criteria include NFC Type 5 compliance, configurable multi-area memory protection, kill-mode security, RF power harvesting behavior, and EEPROM endurance at elevated temperature.
Technical Context
The ST25TV16K-AP6G3 implements a fully autonomous analog front-end with integrated 28.5 pF tuning capacitance, enabling direct connection to external antenna coils without external matching components. Its digital unit enforces ISO/IEC 15693 protocol stack including all subcarrier modes (1 of 4, 1 of 256), coding schemes (Manchester, BPSK), and data rates (26.48 kbit/s standard, 53 kbit/s fast).
Memory management is partitioned into user EEPROM (16 Kbit, organized as 1024 × 4-byte blocks) and system configuration area (protected by 64-bit PWD_0), supporting four independently password-protected user areas with programmable end addresses (ENDA1–ENDA3) and per-area read/write lock granularity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Standard | ISO/IEC 15693 & NFC Forum Type 5 certified - ensures interoperability with commercial NFC readers and inventory systems. |
| Memory Size | 16 Kbit EEPROM (1024 blocks × 4 bytes) - supports firmware metadata, calibration data, or serialized identifiers in compact form factors. |
| Data Rate | Up to 53 Kbit/s Fast Read - reduces tag interrogation time in high-throughput logistics scanning environments. |
| Write Endurance | 1 million cycles at 25 °C - enables field-updatable configuration in industrial maintenance tags. |
| Data Retention | 40 years - guarantees long-term integrity of embedded serial numbers or cryptographic keys without refresh. |
| Operating Temp | –40 to +85 °C - qualified for automotive under-hood labeling, outdoor equipment ID, and industrial asset tracking. |
| Kill Function | Hardware-enforced KILL_MUTE/KILL_ERROR bits - provides irreversible privacy control compliant with GDPR and product recall requirements. |
Pinout & Package
ST25TV16K-AP6G3 is offered in a wafer-level chip-scale package (WLCSP) with two terminals: AC0 and AC1. These are dedicated RF antenna coil connections with no DC bias or digital I/O functionality. The device draws power entirely from the incident RF field and contains no VDD/VSS pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC0 | Antenna Coil Terminal 0 | RF input node for electromagnetic coupling; must be connected only to tuned LC antenna structure - no DC path allowed. |
| AC1 | Antenna Coil Terminal 1 | Completes resonant tank with AC0; internal 28.5 pF capacitance sets nominal resonance near 13.56 MHz when paired with external coil inductance. |
Key Features
| Feature | Design Value |
|---|---|
| NFC Forum Type 5 Certification | Guarantees out-of-box compatibility with Android NFC hosts and enterprise-grade RFID readers without custom driver development. |
| Four-Password Memory Protection | Enables tiered access control: three 64-bit user passwords (PWD_1–PWD_3) plus one 64-bit configuration password (PWD_0) for system register lockdown. |
| Configurable Memory Areas | ENDA1–ENDA3 registers allow dynamic partitioning of 16 Kbit EEPROM into up to four zones with independent read/write permissions - ideal for multi-stakeholder data sharing. |
| Fast Read Protocol Extension | 53 Kbit/s throughput achieved via optimized Manchester decoding and reduced inter-block gaps - cuts scan latency by >40% vs standard ISO/IEC 15693 reads. |
| Hardware Kill Mode | Dedicated KILL register (bits KILL_MUTE/KILL_ERROR) disables RF response permanently - meets EU ePrivacy Directive requirements for consumer electronics deactivation. |
Applications
| Smart Product Authentication | Industrial Asset Tagging |
|---|---|
Use Scenario: Embedded in luxury goods packaging or medical device consumables to verify authenticity at point-of-sale or point-of-use. IC Role / Device Role / Timing Role: Passive NFC tag storing cryptographically signed serial number and batch ID; responds to reader-initiated inventory commands within 10 ms. Use Value: Prevents counterfeiting via hardware-enforced kill mode and write-protection on critical fields - no software patching required. |
Use Scenario: Mounted on factory-floor machinery, test fixtures, or calibration tools to log maintenance history and firmware version. IC Role / Device Role / Timing Role: Contactless EEPROM storing timestamped service records and technician IDs; accessed via handheld NFC reader during scheduled inspections. Use Value: Eliminates manual logbooks; 40-year data retention ensures full lifecycle traceability even for equipment deployed beyond 10 years. |
| Secure Access Credentials | Automotive Service Labels |
Use Scenario: Integrated into employee badges or door-access tokens where credential revocation must be instantaneous and irreversible. IC Role / Device Role / Timing Role: NFC Type 5 tag holding encrypted access profile; disabled via KILL_MUTE command upon staff termination. Use Value: Meets ISO/IEC 27001 physical security controls - no residual RF signature remains after kill activation. |
Use Scenario: Applied to EV battery packs or ADAS ECUs to store production date, software version, and safety certification status. IC Role / Device Role / Timing Role: Temperature-hardened RFID tag readable through plastic housing; retains UID and DSFID across thermal cycling from –40 to +85 °C. Use Value: Enables automated VIN-level diagnostics at service centers using standard NFC smartphones - no proprietary scanner needed. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC Type 5 tag applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP NT3H2111W0FHKH | 16 Kbit EEPROM, same ISO/IEC 15693 support, but lacks hardware kill register; uses software-based lock commands only. | Suitable for non-critical authentication where reversible lockdown suffices; not compliant with GDPR-mandated irreversible deactivation. | Select when cost sensitivity outweighs privacy enforcement requirements and field updates are frequent. |
| ON Semiconductor N24RF16DT | 16 Kbit EEPROM, I²C + RFID dual-interface, but RF side lacks NFC Forum Type 5 certification and fast read mode. | Preferred in mixed-wireless/wired systems needing local MCU access; incompatible with Android NFC Host Card Emulation workflows. | Choose only if I²C debug access is mandatory and NFC reader ecosystem is vendor-controlled. |
Compared with NT3H2111W0FHKH and N24RF16DT, ST25TV16K-AP6G3 uniquely combines NFC Forum Type 5 certification, hardware kill, and 53 Kbit/s fast read - making it the sole option for privacy-critical, high-speed, standards-compliant passive tagging.

FAQ
Does ST25TV16K-AP6G3 require an external power supply?
No. The device is entirely passive and derives operating power from the 13.56 MHz RF field generated by the reader antenna. Its internal analog front-end rectifies and regulates this energy to power the EEPROM and logic circuits - no VDD pin or battery is needed.
How is memory protection configured on ST25TV16K-AP6G3?
Memory protection is implemented via three 64-bit user passwords (PWD_1–PWD_3) stored in the system configuration area and controlled by A1SS–A4SS registers. Each of the four user memory areas can be independently set to allow read-only, password-protected write, or full lockdown - all enforced in hardware without MCU intervention.
What is the function of the ENDA1–ENDA3 registers?
ENDA1–ENDA3 define the ending block addresses of user memory Areas 1–3, enabling flexible partitioning of the 1024-block EEPROM space. Each register uses 8× granularity (e.g., ENDA1 = 0x3F → Area 1 ends at block 0x1FF), allowing up to four contiguous, non-overlapping zones with distinct access policies.
Can ST25TV16K-AP6G3 be reactivated after issuing a KILL command?
No. Once KILL_MUTE is set to '1', the device ceases all RF communication permanently and cannot be powered up or interrogated again - this is a hardware-fused, irreversible state verified by NFC Forum certification testing. KILL_ERROR mode similarly prevents functional operation while returning error code 0xF on valid commands.
