Device Overview

Introduction
Freescale Semiconductor’s MPR084 proximity capacitive touch sensor controller is one of a family of products designed to detect
the state of capacitive touch pads. The MPR084 offers designers a cost-efficient alternative to mechanical keys for control panel
applications.
The MPR084 uses an I2C interface to communicate with the host which configures the operation and an interrupt to advise the
host of status changes. The MPR084 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 MPR084 controls individual touch pads. 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.
1.1.1
Devices in the MPR08X series
The MPR08X series of Proximity Capacitive Touch Sensor Controllers allows for a wide range of applications and
implementations. Each of the products in Table 1 perform a different application specific task and are optimized for this specific
functionality.
