Capacitive touch evaluation kit compliant with IEC/EN 61000-4-6 industry standard
The system has been designed to demonstrate the ability to pass up to 15V noise injection level over the full frequency range of 150kHz to 230MHz for all keys. This performance surpasses the IEC/EN 61000-4-6 Level 3 specification, which goes beyond the requirements of typical consumer and industrial applications. The kit is based on Renesas’ R8C/3xT-A MCUs, the latest line-up of R8C family devices designed for capacitive touch key applications. The R8C touch MCUs incorporate a specialized hardware block called Touch Sensor Control Unit (SCU), which handles touch scanning and processing functions completely independent from the CPU. With this solution, Renesas provides engineers with all of the demonstration, evaluation and development tools needed to get to market with robust touch key solutions for medical, home appliance, consumer and building/office automation systems requiring enhanced human-machine interfaces (HMI).
The touch kit enables engineers to evaluate keypad, slide and wheel configurations (including a 3×4 keypad) for touch sensitivity and noise performance on a single-board system.
