    Datasheet >

    The CMS183x series of products are dedicated touch chips, with a working voltage of 3.0V~5.5V, with super strong anti-conducted disturbance (CS) ability, super anti-EFT ability, high waterproof performance, flexible adjustment of sensitivity, and self-adapting long and short line capabilities. It can be applied to different occasions. Support a variety of query methods, a variety of packaging options to improve design flexibility.


    Features

    > Super strong anti-conducted disturbance (CS) ability, passed 10V conducted immunity test

    > Super anti-EFT interference ability

    > Super anti-radio frequency interference ability, can prevent short-distance, multi-angle mobile phone / walkie-talkie interference

    > Adjustable sensitivity, pass Change the capacitance value of the external capacitor to adapt to different applications

    > Long-press button protection, when any button is pressed for more than 30 seconds, the system will automatically reset. The sensitivity of the buttons is basically the same

    > 3 or more buttons are valid at the same time, the system automatically resets

    > High waterproof performance

    > A variety of ways to query the output button key value, single-wire serial communication, three-wire BCD code communication, one-to-one output

    > Key induction plate shape : any shape (must ensure the contact area with the panel)

    > Key induction plate material: PCB copper foil, metal sheet, flat-top cylindrical spring, conductive rubber, conductive ink, conductive glass ITO layer, etc.

    > Panel material: insulating material, such as Plexiglass, ordinary glass, tempered glass, plastic, wood, paper, ceramics, stone, etc.

    > Panel thickness: 0-12mm, depending on different panel materials

    > Operating temperature: -20°C~85°C

    > Operating voltage: 3.0V-5.5V

    > Package types: SOP8, SOP14 and SOP16
