CAPSENSE™ Controllers

Infineon Technologies CAPSENSE™ Controllers are a Capacitive Sensing solution that has replaced more than 3.5 Billion sensors with a Capacitive touch interface. The CAPSENSE Family is based on Infineon's Programmable System on Chip (PSoC™) platform that provides customers with the flexibility needed to make last-minute changes, offers robust noise immunity, enables quick time to market, and system scalability. Infineon's ultra-low power CY8C20xx6A family is ideal for the most demanding Capacitive Sensing applications. This low-power family is enabled by Infineon SmartSense™ - the advanced Capacitive Sensing algorithm that makes Infineon CAPSENSE easy to use.
