ATmega328 8-Bit AVR MCUs

Microchip Technology ATmega328 8-Bit AVR MCUs are low-power, CMOS 8-bit microcontrollers based on the AVR® enhanced RISC architecture. The devices execute instructions in a single clock cycle to achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz. This allows for optimizing power consumption versus processing speed.
