Creating a capacitive matrix keypad has never been simpler.
This solution supports direct LED drive and configurable LED effects at Power-on. Enabled with Infineon's SmartSense auto-tuning algorithm, it eliminates the need for manual tuning. This advancement enables designers to reduce the UI design task to the PCB layout of the sensor board – the CAPSENSE™ Express controller handles rest.aster time-to-market.
