Engineering Brief
The ST25TV02K is a dual-interface NFC tag IC combining ISO 15693 RFID functionality with energy harvesting capabilities. It provides 2 Kbit of EEPROM memory organized in 64 blocks, accessible via 13.56 MHz RF interface with reading distances up to 1.5 meters depending on antenna design. The chip features an integrated energy harvesting output that can power external circuits or sensors by extracting power from the NFC field, making it ideal for battery-free IoT applications. It includes basic security features such as password protection and supports fast read/write operations with anti-collision for multi-tag environments.
Typical Applications
- NFC energy harvesting for battery-free sensors
- Wireless temperature or environmental data logging
- Asset tracking and identification
- Supply chain management
- Industrial automation and smart labels
- Consumer electronics with NFC wake-up
