BU21079F-E2 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.

Key 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 or 5.0V single power supply
Built-in Power-On-Reset and Oscillator
