Dynamic NFC Tag ICs Expand into New Applications

The near field communications (NFC) ecosystem and associated services expands beyond just payments. NFC enables simplified data exchange, pairing, and wireless connections between two objects when in close proximity to one another. Unlike preceding RFID technology, NFC was designed for applications that require higher levels of security and where larger amounts of data may be exchanged.

Some of the latest NFC tag ICs are considered ‘dynamic.’ Dynamic tag ICs are chips that can communicate two ways: either via the RF interface or a serial port. The dynamic NFC tag chip allows for battery-free operation in RF mode.

One example of a modern NFC tag IC is the ST25DV from STMicroelectronics. It has 4, 16, or 64 Kbits of EEPROM and connects via either the RF interface or its I2C port for a microprocessor connection.

A product equipped with the ST25DV can be tracked on the production floor with no worry about a barcode that might be damaged or dirty. The product being manufactured can be customized to one of several versions with a simple tap of an NFC equipped cell phone, tablet, or card.

Furthermore, thanks to the ST25DV’s ISO 15693 compatibility, long-range operations can be supported as well. The chip combines analog and digital functions and has an analog front end that connects to an external antenna, plus an internal 28.5 pf tuning capacitor.

Applications abound, including automotive (security, customization), medical and pharmaceutical, manufacturing, and more.

At the end of the day, these NFC tag ICs enhance operations with their fast transfer modes and larger memory capabilities.

This reminds me of my blog post several years ago! Wow, has it really been 5 years?
