Datasheet Atmel ATmega328P-AN

ATmega328/P
AVR® Microcontroller with picoPower® Technology
Introduction
® ® The picoPower ATmega328/P 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 ATmega328/P achieves
throughputs close to 1 MIPS per MHz. This empowers system designers to optimize the device for power
consumption versus processing speed. Feature
