產品詳細資訊
BU21078FV is a capacitive sensor controller for switch operation. In addition to a regular simple switch, support matrix switches which are arranged in the matrix sensors. If external noise and temperature drift are detected, the automatic self-calibration is operated. Include LED controller with PWM function.
12 capacitive sensor ports
Supported Matrix switches. Maximum 36 switches
Automatic self-calibration
Continued touch detection
LED controller with PWM function
Inform the detected result of switch operation by interrupt
2-wire serial bus interface
Single power supply
Built-in Power-On-Reset and Oscillator
