HT672B Overview
The HT672B is a RF transponder IC operating with 13.56MHz RF carrier, which provides a low cost batteryless transponder solution with the addition of merely an external inductor. The inductor and internal capacitor form a LC tank which inducing voltage from the radiated 13.56MHz carrier signal generated from the reader antenna. HT672B has a built-in low power RC oscillator which is activated if the induced carrier...
