The ST25DV16K-IER6T3 is a dynamic NFC/RFID tag IC with a dual interface from STMicroelectronics, which incorporates both a contactless NFC/RFID interface and an I2C interface. This IC is part of the ST25DV series, known for its robust and versatile RFID/NFC solutions designed for various applications including consumer electronics, industrial, and IoT devices.

With a 16-Kbit memory capacity, the ST25DV16K-IER6T3 offers ample space for storing user data, accessible via both the RF interface and the I2C interface. This enables seamless interaction between NFC-enabled devices, such as smartphones, and the host system through the I2C connection. The memory is organized into sectors and blocks, offering flexibility in data management and security settings.

The device's energy harvesting capabilities are a standout feature, allowing it to power external components from the energy collected via the RF field, thereby reducing the overall power consumption of the system it's embedded in. This is particularly beneficial for battery-operated devices, extending their operational lifespan and reliability.

The ST25DV16K-IER6T3 supports the ISO/IEC 15693 and NFC Forum Type 5 tag standards, ensuring compatibility with a wide range of NFC devices and RFID readers. It also offers fast data transfer rates and a long-range proximity operating distance, which is advantageous for user convenience and efficient data exchange.

This dynamic tag IC is equipped with a multitude of safety features, including a 32-bit password protection mechanism and a TruST25 digital signature, which guarantees the authenticity of the product for end-users. Additionally, the GPO (General Purpose Output) feature can be used to trigger external events based on the status of the tag, such as incoming RF commands or interrupts.

The ST25DV16K-IER6T3 is available in a small and thin package, making it suitable for integration into compact designs where space is at a premium. Its robust design and wide temperature range ensure reliable operation even in harsh environmental conditions, making it an ideal choice for a broad spectrum of applications.
