Winning Combinations to Design Faster

Smart coffee machine

Coffee maker design with minimal components

Renesas’ coffee machine solution is based on the high-performance RA4 MCU series, a complete solution in a single chip. Integrated system features of the MCU include system control, automatic detection, human-machine interface, and touch control. The touch algorithm enables touch control and automatic water level detection so it can be used simultaneously. Combining the Renesas flow sensor enables automatic control of the coffee output.

System Benefits:

  • The RA4M1 MCU features an integrated capacitive touch sensing unit (CTSU), 12-bit ADC, display, and USB with high performance
  • Ability to design a coffee machine with minimal components
  • High-performance DC/DC and flow sensor
