Smart kitchen appliances have several features, such as color display, touch control and sound feedback. Voice recognition is also an emerging feature for non-contact operation. Sensing functions such as humidity/temperature and gas, can also be added on as an additional feature to these systems.

This reference design shows a multi-HMI function control and sensing solution, with the RA6M3 32-bit microcontroller (MCU) consolidating system control.

System Benefits

  • Single-chip MCU, reduced bill-of-materials (BOM) cost and PCB size
  • High-performance HMI (voice recognition, graphic and sound feedback/adaptive differential pulse-code modulation) can be controlled in one chip
  • High-performance LDO, gas sensor and temperature/humidity sensor for an integrated solution
