CY8C201A0-LDX2I Datasheet - Cypress Semiconductor

Overview
These CapSense Express™ controllers support 4 to 10 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 CapSense Express controller enables the control of 10 I/Os configurable as one capacitive sensing slider (10 segments)[1] or one slider (5 segments) with the rest of the pins as buttons or GPIOs (for driving LEDs or interrupt signals based on various button conditions).
