Capable of converting position and direction of movement into electrical signals based on slight changes in the electrostatic capacitance when lightly touched.

ROHM's electrostatic sensors reduce the load on the host CPU by integrating sensor data processing and application functions into a dedicated IC. Systems can be built with minimal set restrictions using anything from simple touch switches to high precision two-dimensional touch panels.

• The sensing circuitry utilizes unique CV conversion circuit technology to avoid the resistance effects of the sensor electrode material
• Supports both SPI and I²C serial interfaces (BU21010MUV supports I²C only)
• Includes LED illumination functions (fading, PWM control)
  
• Gesture determination function (short press, long press, slide)
