Key Features
- 16 Kbit EEPROM accessible from both ISO 15693 NFC RF interface at 13.56 MHz and I2C host interface simultaneously for dynamic tag applications
- Fast transfer mode enables high-throughput data exchange between NFC reader and host MCU at speeds beyond standard ISO 15693, suitable for firmware update over NFC
- Energy harvesting output pin delivers power harvested from NFC field to the host system, enabling batteryless or battery-backup IoT node designs
Applications
The ST25DV16KC-IE8C3 is used in smart packaging, industrial asset tracking, and IoT device configuration where a product needs to be both tapped by an NFC phone and updated by an embedded microcontroller over I2C. Its energy harvesting feature enables wireless sensor nodes to operate from NFC field power alone during RF interrogation, eliminating the need for a battery in intermittently powered applications. Fast transfer mode also makes it suitable for over-the-air firmware distribution to small microcontrollers in access-restricted equipment.

Frequently Asked Questions
How much EEPROM does the ST25DV16KC-IE8C3 provide, and can both NFC and I2C interfaces access it simultaneously?
The ST25DV16KC-IE8C3 provides 16 Kbit (2 Kbyte) of EEPROM that is accessible from both the ISO 15693 NFC RF interface at 13.56 MHz and the I2C host interface. An internal arbitration mechanism prevents read/write conflicts between the two interfaces, allowing the host MCU to update data over I2C while an NFC reader reads it wirelessly without data corruption.
What is the fast transfer mode in ST25DV16KC-IE8C3, and for which application scenarios does it provide a meaningful throughput advantage?
Fast transfer mode is a proprietary STMicroelectronics extension to the ISO 15693 protocol that increases data transfer rates beyond the standard 26.48 kbps, enabling faster bulk data exchange between the NFC reader and the tag. This is particularly useful for transferring firmware images of several kilobytes to an embedded system over NFC, where standard ISO 15693 throughput would result in transfer times of several seconds.
How does the energy harvesting output on the ST25DV16KC-IE8C3 enable batteryless designs?
The device includes a dedicated energy harvesting output pin that rectifies and regulates power extracted from the 13.56 MHz NFC RF field. This pin can supply up to approximately 5 mW to an external circuit, which is sufficient to power an ultra-low-power microcontroller such as a PIC or MSP430 during an NFC session, allowing sensor data capture and tag memory update without any local battery.
What memory protection features does the ST25DV16KC-IE8C3 offer for securing configuration data in field-deployed products?
The 16 Kbit EEPROM is divided into up to 4 independently configurable protection zones, each with a separate password and access permissions for read and write via both NFC and I2C interfaces. Passwords are 64-bit values, preventing unauthorized modification of calibration constants, product configuration, or security credentials stored in protected zones even when the tag is presented to a reader in the field.
