• Product Introduction

KITMPR03XEVM Touch sensor

The MPR03X is an I2C-interfaced intelligent capacitive touch sensor controller that is ideal for applications with two electrodes (with interrupt function) or three electrodes (with interrupt function disabled). Thanks to its increased sensitivity and many features, the MPR03X can be adapted to a wide range of applications.

Since there is no chip selector, a separate address is required to use the I2C protocol device. Therefore, for the use of two MPR03x devices in the same system, the MPR031 and MPR032 can be assigned different I2C addresses for each part number. In this way, one of the devices can achieve 4-6 electrodes in the final system based on the same I2C bus, without the need for additional communication lines or dedicated hardware.
