Infineon Technologies CY8CMBR2044 CAPSENSE™ Capacitive Button Controller

Infineon Technologies CY8CMBR2044 CAPSENSE™ Capacitive Button Controllers incorporate several innovative features to quickly enable a capacitive touch sensing user interface in designs. Infineon CY8CMBR2044 CAPSENSE Capacitive Button Controllers require no software tools or coding because system configuration is done using hardware. These features allow capacitive buttons to be implemented without learning new tool sets and developing code.

These Infineon Technologies controllers include SmartSense™ auto-tuning, which eliminates manually tuning of a user interface during development and re-tuning during production ramp. The CY8CMBR2044 supports up to four capacitive sensing buttons and four GPOs.
