Device Overview
1.1
Introduction
MPR03X is a small outline, low profile, low voltage touch sensor controller in a 2 mm x 2 mm
DFN which manages up to three
touch pad electrodes. An I2C interface communicates with the host controller at data rates up to 400 kbits/sec. An optional
interrupt output advises the host of electrode status changes. The interrupt output is a multiplexed with the third electrode output,
so using the interrupt output reduces the number of electrode inputs to two. The MPR03X includes three levels of input signal
filtering to detect pad input condition changes due to touch without any processing by the application.
