The ATmega164P-B 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 ATmega164P-B achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
