All rights reserved. www.rohm.com TSZ22111・14・001 14.Jul.2016 Rev.004 Capacitive Controller ICs Capacitive Switch Controller ICs BU21072MUV / BU21078MUV / BU21078FV General Description BU21072MUV/BU21078MUV/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. Features ■ 10 capacitive sensor ports. (BU21072MUV) 12 capacitive sensor ports. (BU21078MUV / BU21078FV) ■ Supported Matrix switches. Maximum 16 switches. (BU21072MUV) Maximum 36 switches. (BU21078MUV / BU21078FV) ■ 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. Applications ■ Appliance that require multiple switches. ■ Information appliance as printer. ■ AV appliance as digital TV and HDD recorder. ■ Notebook PC. Key Specifications ■ Input voltage range ■ Operating temperature range ■ Operating current ■ Scan rate 3.0 to 5.5V -20 to 85°C 3.5mA (Typ.) 16msec (Typ.)
