The Microchip low-power, CMOS 8-bit microcontrollers are built on the AVR enhanced RISC architecture. These devices execute instructions in a single clock cycle, enabling CPU throughput close to one million instructions per second (MIPS) per megahertz. This capability allows system designers to optimize power consumption in relation to processing speed, providing flexibility in balancing performance and energy efficiency.
