Note:

The large center pad underneath the QFN/MLF packages is made of metal and internally con-

nected 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.

2. 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.

3. Overview

The ATmega329/3290/649/6490 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architec-

ture. By executing powerful instructions in a single clock cycle, the ATmega329/3290/649/6490 achieves throughputs

approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
