ATmega328PB
ATmega328PB Summary Datasheet
Introduction
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 1MIPS per MHz. This empowers system designers to optimize the device for power
consumption versus processing speed.
