8-bit AVR Microcontrollers
ATmega328/P
DATASHEET COMPLETE
Introduction
The Atmel® 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 1MIPS per MHz. This empowers system
designer to optimize the device for power consumption versus processing
speed.
