CY8C20110-SX2I Datasheet

CapSense Express™ Button Capacitive Controllers


These CapSense Express™ controllers support four to ten capacitive sensing (CapSense) buttons. The device functionality is configured through an I2C port and can be stored in onboard nonvolatile memory for automatic loading at power-on. The CY8C20110 is optimized for dimming LEDs in 15 selectable duty cycles for back light applications. The device can be configured to have up to 10 GPIOs connected to the PWM output. The PWM duty cycle is programmable for variable LED intensities.
