xb Number of products: CBM7026

   CBM7026 is a capacitive touch button controller launched by Chipbond Technology Corporation . This chip is mainly used for

Appliances, consumption costs electrical key sub-field detection, and other industrial, with high sensitivity, anti-interference ability of microwave, anti

Water, dust, highly depend of other advantages. Can widely replace traditional mechanical buttons.

CBM7026 uses self-developed 8-Bit MCU processor, I2C-slave / Host, UART interface transmission

Key input letter information. I / O Mode can also be used to transmit key information, making it easier to develop application systems without analysis

Communication protocol package. Capacitive touch sensors can be made directly on the PCB, with few peripheral devices and system assembly

This is superior to the conventional press key scheme. The adaptive touchpad capacitance detection range is 1pF to 40pF.
