ATMEGA328P-AU

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P21P22-P24
8-bit AVR Microcontrollers
ATmega328/P
DATASHEET SUMMARY
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.
