the atmega329/3290/649/6490 is a low-power cmos 8-bit microcontroller based on the avr enhanced risc architecture.
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.
