The ST25DV64K-JFR6D3 from STMicroelectronics is an innovative dynamic NFC/RFID tag IC that offers a unique combination of flexibility, power, and security for near-field communication applications. It is part of ST's ST25DV series, which is designed to provide wireless connectivity to any electronic device, enabling a wide range of NFC applications such as smart advertising, machine maintenance, product authentication, and NFC-based configuration.

This dynamic tag features a 64-Kbit EEPROM, divided into areas that can be protected by passwords to restrict access to authorized users only. The EEPROM can be accessed via an I2C interface or by an NFC-enabled phone or reader. The dual-interface feature allows for seamless communication, regardless of the power state of the host device.

The ST25DV64K-JFR6D3 supports the ISO/IEC 15693 and NFC Forum Type 5 tag standards, ensuring compatibility with a wide range of NFC devices. The tag IC is also capable of energy harvesting, which means it can power external components with the energy it receives from the NFC reader field.

This dynamic tag comes in an ultra-compact SO8N package, making it ideal for integration into space-constrained applications. The device also features a wide temperature range, making it suitable for industrial applications that require robust performance under varying environmental conditions.

Key features of the ST25DV64K-JFR6D3 include:

• 64-Kbit EEPROM with byte granularity
• I2C interface and NFC RF communication
• Fast transfer mode capabilities
• Energy harvesting support
• Password protection for secure data access
• Multiple counter functions with tamper detection
• Long-range RFID/NFC functionality

With its robust set of features, the ST25DV64K-JFR6D3 is an excellent choice for designers looking to add NFC functionality to their products while ensuring secure data transfer and user-friendly interaction.
