the atmega164pa/324pa 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
atmega164pa/324pa achieves throughputs approaching 1 mips per mhz allowing the system
designer to optimize power consumption versus processing speed.
