CapSense Controllers Overview

smartsense

Cypress is the world leader in Capacitive Sensing technologies. Our broad range of solutions provide robust noise immunity, enable quick time to market and system scalability and have replaced more than 3.5 Billion sensors over the past several years. The CapSense® portfolio ranges from simple buttons and sliders to more sophisticated solutions integrating other system components to reduce total BOM cost and form factor. Key to this market space: low power consumption, wide voltage range operation, small form factor packaging and performance across a variety of overlay materials and thicknesses. Cypress low power technology enables supply current in run mode as low as 15uA per button and operating voltage as low as 1.71volts. Industry leading small form factor packaging such as WLCSP that is under 2mm x 2mm and a wide variety of Small Outline and QFN packages optimize board space. Advanced sensing techniques easily provide finger detection with up to 15mm glass or 5mm plastic overlays. This portfolio also enables additional User Interface functionality such as LED effects, proximity and water rejection. Cypress recently introduced the revolutionary SmartSense™auto tuning solution to the CapSense portfolio. This innovation drives the next quantum step of simplicity for adding the capacitive sense user experience to an ever-broader range of end products.

CapSense® Express is easy to use and supports simple button or button / slider designs with up to 10 capacitive buttons or up to 5 capacitive buttons and 1 slider.

CY8CMBR2044, CY8C201xx

CapSense® - supports up to 33 capacitive buttons and 6 sliders and features such as proximity, water rejection and LED effects.

CY8C20x34, CY8C20xx6A

CapSense®Plus our full featured offering handles up to 44 capacitive buttons and 8 sliders. Supporting LED effects, proximity detection, water rejection as well as further system level integration of various analog and digital blocks to reduce total BOM cost
