1.1
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.
The MPR083 uses an I
host of status changes. The MPR083 includes a piezo sounder drive which provides audible feedback to simulate mechanical
key clicks. The MPR08X family has several implementations to use in your design including control panels and switch
replacements. The MPR083 controls rotary and linear sliders. Other members of the MPR08X family are well suited for other
application interface situations such as individual touch pads or rotary/touch pad combinations.
Freescale offers a broad portfolio of proximity sensors for products ranging from appliance control panels to portable electronics.
Target markets include consumer, appliance, industrial, medical and computer peripherals.
