ATMEGA328PB-AU

The picoPower ATmega328PB 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 ATmega328PB achieves throughputs close to 1 MIPS per MHz. This empowers system designers to optimize the device for power consumption versus processing speed.
