com CY8C20110 CapSense Express™-10 Configurable GPIOs with PWM Control Features ■ Overview The CapSense ExpressTM controller allows the control of 10 IOs configurable as capacitive sensing buttons or as GPIOs for driving LEDs or interrupt signals based on various button conditions.
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 user has the ability to configure buttons, outputs, and parameters through specific commands sent to the I2C port.
The IOs have the flexibility of mapping to capacitive buttons and as standard GPIO functions such as interrupt output or input, LED drive, and digital mapping of input to output using simple logical operations.
This enables easy PCB trace routing and reduces the PCB size and stack up.
CapSense Express products are designed for easy integration into complex products.
