What is the feature of a new capacitive touch IP on the RX130?
What are the merits that manufacturers can obtain by using a new capacitive touch IP?


The RX130 Group of MCUs features a new capacitive touch IP that supports both self-capacity and mutual-capacity for improved robustness and sensitivity.

The capacitive touch sensor also significantly improves noise immunity and sensitivity for operation in wet conditions or dirty conditions.

This allows manufacturers to apply touch keys to a variety of challenging, non-traditional materials, such as wood, glass, or thick acrylic, opening up capacitive touch to a wider range of use in wet materials, while reducing safety or malfunction risks.
