Note:
The large center pad underneath the MLF packages is made of metal and internally connected to
GND. 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.
1.1 Disclaimer
Typical values contained in this datasheet are based on simulations and characterization of
other AVR microcontrollers manufactured on the same process technology. Min and Max values
will be available after the device is characterized.
