STMicroelectronics ST25TV02K-AP6F9

Overview

ST25TV02K-AP6F9 from STMicroelectronics is an NFC Forum Type 5 contactless RFID tag IC compliant with ISO/IEC 15693, featuring 2-Kbit EEPROM, tamper-detect capability, TruST25 digital signature, and dual-mode privacy protection (Kill and Untraceable modes). It operates at 13.56 MHz, supports fast read up to 53 Kbit/s, and delivers 60-year data retention with 100 k write cycles - deployed in secure product authentication and anti-counterfeiting systems.

For engineers reviewing the ST25TV02K-AP6F9 datasheet, ST25TV02K-AP6F9 pinout, ST25TV02K-AP6F9 application, or ST25TV02K-AP6F9 equivalent, key selection criteria include RF interface security architecture, tamper-detect loop implementation, EAS integration, and configurable memory partitioning with encrypted password protection for user and configuration areas.

Technical Context

The ST25TV02K-AP6F9 implements a fully autonomous RF interface with internal tuning capacitance (23 pF / 99.7 pF), enabling direct connection to external antenna coils without external matching components. Its ISO/IEC 15693-compliant transceiver supports all subcarrier modes (1-of-4, 1-of-256), data rates (26.48 kbit/s, 53 kbit/s), and modulation schemes (ASK, PSK).

Memory management is split into user memory (2 Kbits, organized in 64 blocks of 4 bytes) and system configuration area containing protected registers for AFI/DSFID, UID (8-byte), TruST25 signature, tamper detect status, and kill/untraceable mode control - all accessed via dedicated Read/Write Configuration commands requiring encrypted password sessions.

FAQ

What is the function of the TD0 and TD1 pins?

TD0 and TD1 form a dedicated tamper-detect loop interface that monitors continuity of an external conductive trace. An open or short circuit between these pins during RF field presence triggers a persistent tamper flag in the system configuration area, used to invalidate digital signatures or disable functionality in security-critical applications.

How does the TruST25 digital signature work?

TruST25 is a hardware-generated ECDSA signature bound to the chip's unique 64-bit UID and factory-programmed parameters. It is stored in the system configuration area and verified using ST's public key - enabling third-party validation of chip authenticity without exposing private keys or requiring cloud connectivity.

Can ST25TV02K-AP6F9 be used without an external antenna coil?

No - the device requires an external LC tank connected between AC0 and AC1. It contains internal tuning capacitance (23 pF or 99.7 pF selectable via configuration), but no integrated inductor. Antenna design must meet ISO/IEC 15693 inductance and Q-factor requirements for reliable 13.56 MHz coupling.

What happens when the Kill command is executed?

Upon successful presentation of the 32-bit PWD_KILL password, the KILL_MUTE bit is set, rendering the device permanently unresponsive to all RF commands - including Inventory, Read, and Write. The tag emits no carrier signal and becomes electrically silent, satisfying irreversible disablement requirements in privacy-sensitive deployments.
