Overview

Compared with traditional mechanical buttons, capacitive touch keyhas the advantages of long service life, low wear resistance, fashionable appearance and low cost, and are widely used in various electronic products. The CH55X series MCU integrates 6 touch keydetection channels to help customers quickly implement touch buttons.

Program introduction

CH55X series MCU integrates 6 touch button detection channels, 6 touch keys can be realized in self-capacitance mode, and 15 touch keys can be realized in mutual capacitance mode. Typical touch forms include touch keys, spring touch keys, and touch key sliders.
