The widespread initiative among electronic manufacturers to boost the power efficiency of their products has spurred the development of new microcontrollers. Problem-solving system-design solutions, like Renesas’ RX100 MCUs, save power while delivering strong performance, functions and capabilities. This white paper highlights the low-power capabilities of 32-bit RX100 MCUs and shows how system engineers can apply them to design battery-powered products within extremely tight power dissipation limits.
