Our RX100 and RX200 series products are equipped with high-sensitivity, noise-resistant second-generation Capacitive Touch Sensing Unit (CTSU) Intellectual Property (IP). The products are used in operation panels for applications ranging from home appliances to industrial equipment. The new RX600 series products, also equipped with second-generation touch IP, are scalable.

In addition, the RX100-series products are available with third-generation touch IP (CTU2L, CTUS2SL), which offers dramatically higher noise immunity – as well as water resistance – for an even wider range of applications.

RX Capacitive Touch Solutions

Demo Videos - Check out how easy it is to implement high function, high performance capacitive touch applications.

Capacitive Touch Evaluation System for RX130 - The RX130 capacitive touch evaluation system makes it easy for users to evaluate touch solutions offered by Renesas. You can start evaluating immediately out of the box using the board and software included in each kit.

QE for Capacitive Touch: Development Assistance Tool for Capacitive Touch Sensors - The QE for Capacitive Touch development assistance tool supports the development of embedded systems which use capacitive touch sensors.

Touch-Free User Interface Reference Design - The 3D Gesture Reference Design is a solution that can detect the position (x, y and z coordinates) of a hand in space using Renesas' capacitive touch solution. Standard (160mm2) and small (80mm2) versions are available.
