简介

本设计展示了一款厨房抽油烟机,利用瑞萨的电容式触摸传感单元技术(CTSU)实现非接触式控制。RA2 MCU 系列提供了一个单芯片完整解决方案,得益于其集成的 16 位 SAR ADC、24 位 sigma-delta ADC、触摸控制和低功耗性能。此外,瑞萨 LDO、运算放大器和三端双向可控硅开关器件等高性能电源和模拟系统的组合可用在带触摸面板功能的家用电器(洗衣机、IH 烹饪加热器)中。

系统优势:

  • 内置高触摸灵敏度 CTSU,以支持触摸键和 2D 手势输入。增强的抗噪性、灵敏度和耐水性非常适合在潮湿环境(如厨房或浴室)中使用的消费类电子产品。
  • 高性能 LDO、运算放大器和三端双向可控硅开关器件提供了完整解决方案。
