MCU 8Bit ATmega AVR RISC 32KB Flash 3.3V/5V 32Pin TQFP
**Overview**
The ATmega328P 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 ATmega328P achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
