Engineering Brief
The ST25DV64KC is a dynamic dual-interface NFC/RFID tag IC offering both contactless RF (13.56 MHz) and wired I2C communication to a host microcontroller. It features 64 Kbit of EEPROM with fast transfer mode, energy harvesting capability to power external circuits, and a configurable GPO interrupt pin for mailbox-based communication between RF and I2C sides. Security includes multi-area password protection and write-lock features, making it ideal for IoT applications requiring wireless configuration, data exchange, and low-power operation.
Typical Applications
- IoT sensor data logging and wireless retrieval
- Smart shelf and inventory management
- Consumer electronics pairing and configuration
- Medical device tracking and authentication
- Industrial asset monitoring with energy harvesting
- Brand protection and anti-counterfeiting
