  Note: The large center pad underneath the QFN/MLF package is made of metal and internally connected to AVSS. It should be soldered or glued to the board to ensure good mechanical stability. If the center pad is left unconnected, the package might loosen from the board. It is not recommended to use the exposed paddle as a replacement of the regular AVSS pins.
