... This saves valuable engineering time, test time, production yield loss, and speeds the time to volume. The CY8CMBR2044 CapSense controller supports up to four capacitive sensing buttons and four GPOs. The GPO is an active low output controlled directly by the CapSense input making it ideal for a wide variety of consumer, industrial, and medical appli- cations ...
