Dishwashers require fine-grained control over water pumps, complex system control over valves, and so on. To meet these requirements, Renesas Electronics supplies RX Family and RL78 Family microcontrollers, among others, as solutions for system control and operation, as well as semiconductor devices such as control TRIACs, and photocouplers. These chips are designed to meet demand for advanced functionality, high-performance, reduced power consumption, and lower cost.
