Microwave Oven (High-End)
详情介绍
Overview
Renesas has a broad lineup of microcontroller products suitable for microwave ovens. These include 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 R8C/3xT, which incorporates a touch detection circuit.
