Overview

The ST25DV02K-W1/2 is an ISO 15693 and NFC Forum Type 5 tag, with one or two pulse width modulation (PWM) outputs and 2 Kbits of electrically erasable programmable memory (EEPROM).It offers two interfaces. The first delivers up to 2x independent PWM output signals and the second is an RF link activated by the received carrier electromagnetic wave.The PWM outputs are configured at boot time, and can be updated live through RF link. RF and PWM are independently powered and can work in stand-alone mode.The ST25DV02K-W1/2 contains 256 bytes (64 blocks) of memory for User data. This memory is accessible through the RF interface, following ISO/IEC 15693 or NFC Forum Type 5 Tag recommendations.The device is based on technology and design solutions for which there are pending patents.Discovery kit for the ST25DV-PWM NFC/RFID tag IC...

Wiki Reference

Wireless communication, also known simply as wireless, refers to the transfer of information between two or more points without the use of physical conduits like electrical wires or optical fibers. This technology commonly utilizes radio waves, allowing for communication over short distances, such as with Bluetooth, or very long distances, such as with deep-space radio communications. Wireless communication encompasses a wide range of applications, including two-way radios, cellular phones, PDAs, wireless networking, GPS units, and many other devices that operate without the need for physical connections. The term "wireless" has been used historically to describe early radio technology and was later revived in the 1980s and 1990s to distinguish digital communication devices that do not require physical wires. Today, wireless technology enables a variety of services, including mobile and interplanetary communications, that would be impossible or impractical to achieve with wired connections. The telecommunications industry commonly uses the term "wireless" to refer to systems that utilize energy, such as radio waves and acoustic energy, to transfer information over short or long distances without the need for physical wires.
