2. 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.
