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.

Fingerprint Sensor Based on OLED Microdisplays

Posted May 29, 2017 12:00 AM by Engineering360 eNewsletter

An optical fingerprint sensor integrates an OLED microdisplay as a light source on a microchip along with photodiodes. With the technology developed at Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology, Germany, objects can be illuminated as the reflected light is detected and analyzed.

Inductors Have Integrated Shielding

Posted February 13, 2017 12:00 AM by Engineering360 eNewsletter

A commercial version of Vishay's Automotive Grade IHLE series of low-profile, high current inductors integrate e-shields to reduce EMI. By eliminating the need for expensive board-level Faraday shielding to lower EMI, the devices reduce costs and save board space.
