BU21078FV Overview
BU21072MUV/BU21078MUV/BU21078FV is a capacitive sensor controller for switch operation. In addition to a regular simple switch, support matrix switches which are arranged in the matrix sensors. If external noise and temperature drift are detected, the automatic self-calibration is operated.
