This design demonstrates a kitchen range hood that utilizes Renesas’ capacitive touch sensing unit technology (CTSU) for touchless control. The RA2 MCU series provides a complete solution in a single chip thanks to the integrated 16-bit SAR ADC, 24-bit sigma-delta ADC, touch control, and lower power performance. Additionally, the combination of high performance power and analog systems from Renesas’ LDOs, op amps and triacs can be utilized in other home appliances (washing machines, IH cooking heaters) that require touch panel functionality.

System Benefits

  • Built-in high-touch sensitivity CTSU to support touch key and 2D gesture input. Improved noise immunity, sensitivity and water resistance is an ideal match for consumer electronics products that are used in wet environments, such as the kitchen or bathroom.
  • High-performance LDO, op amps and triacs provide a full solution.
