STMicroelectronics ST25TV02K-AP6G9

Overview

ST25TV02K-AP6G9 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-AP6G9 datasheet, ST25TV02K-AP6G9 pinout, ST25TV02K-AP6G9 application, or ST25TV02K-AP6G9 equivalent, key selection considerations include RF interface security architecture, tamper-detect loop implementation, EAS enablement, and password-protected memory partitioning across two or three user areas.

Technical Context

The ST25TV02K-AP6G9 implements a fully autonomous RF-powered architecture with no external power supply required. Its ISO/IEC 15693-compliant interface supports all subcarrier modes (1 of 4, 1 of 256), coding schemes (Manchester, BPSK), and data rates (26.48 kbit/s, 53 kbit/s), including proprietary Fast Read commands for accelerated inventory.

Memory management is split into user memory (2-Kbit EEPROM, organized in 64 blocks × 4 bytes) and system configuration area (nonvolatile registers), each protected by distinct encrypted passwords: 32-bit for Area 1/2 or 64-bit for two-area mode, plus separate 32-bit configuration and kill passwords. Tamper detection uses differential loop sensing on TD0/TD1 pins with open/short event capture.

Key Specifications

Pinout & Package

FAQ

What is the purpose of the TD0 and TD1 pins?

TD0 and TD1 form a dedicated tamper-detect loop interface that monitors continuity between the two pins. An open or short circuit on this loop triggers a persistent tamper flag in the system configuration area, enabling forensic detection of physical intrusion or unauthorized disassembly. This feature is implemented in silicon and requires no external components beyond the loop wire.

How does the Kill mode differ from Untraceable mode?

Kill mode permanently disables all RF communication by muting responses to all commands - it is irreversible and requires presentation of the 32-bit PWD_KILL password. Untraceable mode temporarily masks the UID during inventory while preserving memory contents and allowing future reactivation - it also uses PWD_KILL but does not alter device functionality beyond UID suppression.

Can the ST25TV02K-AP6G9 operate without an external antenna?

No. The ST25TV02K-AP6G9 has no integrated antenna and relies entirely on an external LC tank connected across AC0 and AC1. Internal tuning capacitances (23 pF and 99.7 pF) allow optimization for different antenna geometries, but RF power harvesting and communication require proper impedance matching and resonance tuning at 13.56 MHz using discrete or PCB-trace antennas.

What memory protection options are available for user data?

User memory can be partitioned into two or three independent areas, each protected by its own 32-bit or 64-bit encrypted password. Access rights (read-only, write-only, read/write, or read-locked) are configured per area via AiSS registers. Additionally, individual 4-byte blocks can be permanently locked using the Lock Block command - a hardware fuse-like operation that cannot be reversed.
