Rushmore (1CA037) Touch AFE
Rushmore is a capacitive sensing analog front end ASIC that is utilized by various Cirque platforms including the GT4 touch screen platform, GlidePoint® Gen4 trackpads, and various gaming solutions including the VR Grip™ platform. Rushmore provides a highly flexible foundation for a touch input system. By leveraging the power of a separate microcontroller, various implementation configurations are possible. Additionally, multiple Rushmore AFEs can be scaled for larger applications such as secure ATM touch screens.
