8-bit AVR Microcontroller
ATmega328PB
DATASHEET COMPLETE
Introduction
The Atmel
®
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 designer to optimize the
device for power consumption versus processing speed.
