... Device Overview 1.1 Introduction Freescale Semiconductor’s MPR083 proximity capacitive touch sensor controller is one of a family of products designed to detect the state of capacitive touch pads. The MPR083 offers designers a cost-efficient alternative to mechanical rotary switches for control panel applications. 2 The MPR083 uses interface to communicate with the host which configures the operation and an interrupt to advise the host of status changes ...
