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
