ST25DV04KC-JF6D3 - Dynamic NFC/RFID Tag IC

The ST25DV04KC-JF6D3 from STMicroelectronics is a dynamic NFC/RFID tag IC with a dual interface that not only provides long-range radio frequency communication but also features fast data transfer and convenient NFC connectivity. This product is part of the ST25DV series, which is designed to deliver a flexible and cost-effective solution for a wide range of applications such as consumer electronics, industrial systems, and Internet of Things (IoT) devices.

This NFC tag features a 4-Kbit EEPROM memory that can be accessed through either an RF interface compliant with ISO 15693 and NFC Forum Type 5 tag or an I2C interface. This dual-interface approach allows for seamless interaction between the tag and NFC-enabled phones, tablets, or readers, as well as microcontrollers or other I2C-capable devices.

The ST25DV04KC-JF6D3 boasts an energy harvesting capability that can power external components with the energy from the RF field, thus enabling battery-less solutions. Additionally, it offers a unique and flexible protection system, including user-configurable memory access rights, a password protection system for the I2C interface, and a lockable RF configuration.

Its fast transfer mode capability enhances system performance by allowing rapid exchanges between the tag and an NFC device or an I2C master. The product also supports a wide range of operating temperatures, making it suitable for harsh environments.

Key features of the ST25DV04KC-JF6D3 include:

• 4-Kbit EEPROM with NDEF support
• Dual interface: RF and I2C
• Energy harvesting capabilities
• Multiple security features
• Fast data transfer mode
• Endurance of 1 million write cycles
• Data retention of 40 years
• ISO 15693 and NFC Forum Type 5 compliant

The ST25DV04KC-JF6D3 is delivered in a small, surface-mount UFDFPN8 package, which is ideal for applications where space is at a premium. This dynamic tag IC is a perfect choice for designers looking to add NFC functionality to their products with minimal power consumption and robust security features.
