Renesas Electronics Smart Coffee Machine

More About Renesas Electronics

Renesas Electronics Smart Coffee Machine solution is based on the RA4 MCU series, enabling the designing of a coffee machine with minimal components. The microprocessors feature an integrated capacitive touch sensing unit (CTSU), 12-bit ADC, display, and USB with high-performance system control, automatic detection, human machine interface (HMI), and touch control. The touch algorithm of this Renesas solution enables touch control and automatic water level detection so that it can be used simultaneously. Combining the Renesas flow sensor enables automatic control of the coffee output.
