ATmega328PB
AVRВ® Microcontroller with Core Independent Peripherals
and PicoPowerВ® Technology
Introduction
В® В® 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. Features
