Cypress CY8CMBR2044 Capacitive Button Controllers

Cypress Semiconductor CY8CMBR2044 CapSense® Capacitive Button Controllers incorporates several innovative features to quickly enable a capacitive touch sensing user interface in your next design. Cypress Semiconductor 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 Cypress Semiconductor 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. The CY32080-MBR Auto-Tuning Kit is a development kit designed to showcase the features of the CY8CMBR2044.
