General Description  
Key Specifications  
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.
