ATmega328P 8-Bit AVR Microcontroller (Arduino bootloaded)

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.
