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. The four key blocks that make up these devices are: a robust capacitive sensing core with high immunity against radiated and conductive noise, control registers with nonvolatile storage, configurable outputs, and I2C communications. The user can configure registers with parameters needed to adjust the operation and sensitivity of the CapSense buttons and outputs and permanently store the settings. The standard I2C serial communication interface enables the host to configure the device and read sensor information in real time. The I2C address is fully configurable without any external hardware strapping.
