Proximity Capacitive Touch Sensor Controllers

MPR031/2

2- or 3-pad touch sensor controllers

Overview

Mechanical buttons and switches for

touch user interfaces are becoming a thing

of the past. Proximity capacitive touch

sensors in simple linear or rotational sliders

offer significant advantages for numerous

applications. They are more convenient to

use with no moving parts to wear out, more

energy efficient and are more easily integrated

to create an intelligent system. Freescale’s

MPR031 and MPR032 proximity capacitive

touch sensor controllers are CMOS-based

state machines that simplify designing

numerous touch applications for Bluetooth

headsets, mobile phones, multimedia players,

remote controls and other low-power,

handheld, electronic products.

The MPR031 and MPR032 devices have

several implementations to use in your design

including touch pads and switch replacements.

The MPR03x devices control up to three touch

pads. The MPR03x can communicate via the

inter-integrated circuit (I

optimized to manage two electrodes with

interrupt functionality, or three electrodes with

the interrupt disabled. It can accommodate a

wide range of implementations due to increased

sensitivity and a specialized feature set.

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.
