Note:
The large center pad underneath the QFN/MLF packages is made of metal and internally
connected to GND. It should be soldered or glued to the board to ensure good mechani-
cal stability. If the center pad is left unconnected, the package might loosen from the
board.
Disclaimer
Typical values contained in this datasheet are based on simulations and characteriza-
tion of other AVR microcontrollers manufactured on the same process technology. Min
and Max values will be available after the device is characterized.
