ATMEGA168PB-MU

The ATmega48PB/88PB/168PB 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 ATmega48PB/88PB/ 168PB achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
