General Description
The eKTF5832 is an 8-bit microprocessor and supports 24 touch sensor pin. The board material can accept the PCB/film, low cost ITO material process. For Slider application, 4~6 sensor pins per slider or dual slider are supported. The slider function is provided with 256 Steps of sliding resolution. In addition to slider sensor pins, the system also supports up to 20 touch buttons.
The eKTF5832 can auto-calibrate the parameters for a wide range of capacitance on the touch button sensor. After power-on, automatic adjustment of the external environment, not just touch gestures influence. If the sensor environmental conditions are changed (temperature/shift, etc.), it will automatically recalibrate the sensor capacitance to adjust and compensate capacitance shift. It supports touch sensor for small surface area or sketchpad sensor width relatively small distance, allowing small 3C product design. The sensor cable length can be quite large-scale, and supports the need for large-volume products. It can be compatible with multi-product program design.
