HT672B Datasheet PDF - Holtek Semiconductor

General Description
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.
