Key Features
- 64-Kbit EEPROM accessible via both NFC RF interface (ISO 15693) and I2C bus, enabling seamless wireless and wired data sharing in one device
- Fast transfer mode supporting high-speed NFC data exchange at rates above standard ISO 15693, accelerating bulk configuration and data logging use cases
- Integrated energy harvesting output pin providing RF-powered supply to an external MCU or sensor from a standard NFC reader field
- Configurable memory partitions with password-protected zones enabling secure multi-application data storage in a single tag IC
Applications
The ST25DV64KC-IE8C3 is designed for IoT sensor nodes, smart packaging, and asset tracking applications where wireless NFC configuration and data readout complement a wired I2C host controller. Its energy harvesting capability allows the tag to power a companion microcontroller or sensor from a nearby NFC reader field, enabling batteryless data capture for condition monitoring, logistics labels, and industrial asset tags. The 64-Kbit EEPROM and password-protected memory zones support multi-vendor supply chain workflows where different parties need access to distinct data regions on the same physical tag.

Frequently Asked Questions
How does the ST25DV64KC-IE8C3's dual interface allow both NFC readers and a host MCU to access the 64-Kbit EEPROM?
The ST25DV64KC-IE8C3 exposes its 64-Kbit EEPROM through two independent interfaces: an ISO 15693-compliant NFC RF interface for contactless smartphone or reader access, and an I2C bus operating at up to 1 MHz for wired host MCU access. Both interfaces share the same memory array, allowing an MCU to write sensor data at 1 MHz via I2C while an NFC reader retrieves it wirelessly without physical connectors.
What energy harvesting capability does the ST25DV64KC-IE8C3 provide for batteryless IoT sensor designs?
The ST25DV64KC-IE8C3 includes an energy harvesting output pin that rectifies power from an incident 13.56 MHz NFC field and delivers it to an external load. The harvested voltage can power a low-energy microcontroller or sensor for short bursts, enabling batteryless smart label or asset tag designs to perform a sensor reading and write it to EEPROM during an NFC reader interaction, without requiring a dedicated battery or external power supply.
How do the password-protected memory zones in the ST25DV64KC-IE8C3 support multi-stakeholder supply chain applications?
The ST25DV64KC-IE8C3 supports up to 4 configurable memory area partitions, each independently protected by a 64-bit password. A manufacturer can restrict write access to one zone for product authentication data while a logistics partner writes shipping records to a second zone and an end customer reads a third zone with no password. This multi-zone security model enables a single 64-Kbit tag to serve multiple parties across a product's lifecycle without exposing sensitive data across zones.
For an NFC-enabled smart packaging design, how does the fast transfer mode of the ST25DV64KC-IE8C3 reduce read-write time compared to standard ISO 15693?
Standard ISO 15693 operates at 26.48 Kbps in single-subcarrier mode. The ST25DV64KC-IE8C3's fast transfer mode increases the data rate significantly, allowing bulk EEPROM transfers of several kilobytes to complete in hundreds of milliseconds rather than several seconds. This is critical for smart packaging applications where a consumer or logistics scanner passes an NFC reader over a label briefly, and the full 64-Kbit product configuration or sensor log must be transferred within the time the reader field is active.
