General Description BU21079F is a capacitive switch controller used for operating switches. Low power consumption is achieved using the intermittent operation mode. In addition to a regular simple switch, it supports matrix switches which are arranged in the matrix sensors. If external noise and temperature drift are detected, the automatic self-calibration is activated. Features
- 8 capacitive sensor ports
- Supports matrix switches. Maximum of 16 switches.
- Automatic self-calibration
- Continued touch detection
- Sends an interrupt when there is a detected result of switch operation
- 2-wire serial bus interface
- 3.3V...
