As the adoption of capacitive touch interfaces expands rapidly, the use of conventional mechanical keys with limited functions are effectively being replaced. Panels with user-friendly designs can be operated using actions such as finger touches and swipe motions. Capacitive touch technology allows even devices designed for complex and highly skilled operations to be controlled with intuitive finger movements.
As the capacitive touch operation scene expands, panel sensitivity and high-noise resistance have become key requirements in achieving accurate switching movements and sophisticated operational performance. There is also a demand for features involving environmental tolerance to water, dirt or temperature variations. In addition to these requirements, development periods and costs are also hurdles that need to be considered and overcome.
Renesas offers revolutionary design to switching devices and equipment with our 2nd generation capacitive touch solution that enables a user-friendly environment to support manufacturing processes and lowers hurdles in capacitive touch sensor development.
This human machine interface (HMI) solution kit is mounted with an LCD segment display circuit, sound reproducing circuit, capacitive touch circuit, etc. It can facilitate the development and evaluation of HMI and USB-applied products such as electric home appliances and healthcare products with built-in communication functions.
The RX130 Capacitive Touch Evaluation System is designed for easy evaluation of capacitive touch solutions offered by Renesas. With this system, evaluation may be conducted immediately after purchase, as the board and software are included in the kit.
QE for Capacitive Touch makes it easy to adjust the sensitivity of the touch buttons that are necessary for embedded system development that uses capacitive touch technology, shortening time to market. This tool supports the RX Family of 32-bit microcontrollers (MCUs).
