ATmega328P Datasheet
ATmega328P Datasheet Complete Download - 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.
