描述 Description

The eKT5205 is a microprocessor with 4kx15bit programmable ROM and 432 byte SRAM.The system application supports up to 12 touch buttons which can be applied to One-Line type touch sensors.

The button of eKT5205 can be used in the different application supports up to Slider function, Anti-Ignition Noiseetc. It can overcome operation voltage impulse noise from Igniter of water heater generate.

The eKT5205 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.
