Renesas has a broad lineup of microcontroller products suitable for microwave ovens. These include RX13T Group of high performance MCU, RL78/L1x Series of LCD MCUs, which are built around a high-performance CPU and integrate a PWM (Pulse Width Modulation) function for IGBT control and A/D converters to handle a variety of sensor inputs, and RX130/RX230 Group, which incorporate a touch detection circuit. Also, recent trend of voice command operation for advanced HMI is realized by the RX651 group.
