Peripheral Touch Controller (PTC) offers built-in hardware
for capacitive touch measurement on sensors that function as buttons,
sliders, and wheels. The PTC supports both mutual and self-capacitance
measurement without the need for any external component. It offers superb
sensitivity and noise tolerance, as well as self-calibration, and minimizes the
sensitivity tuning effort by the user.
The PTC is intended for autonomously performing capacitive touch sensor
measurements. The external capacitive touch sensor is typically formed on a
PCB, and the sensor electrodes are connected to the analog charge
integrator of the PTC using the device I/O pins. The PTC supports mutual
capacitance sensors organized as capacitive touch matrices in different X-Y
configurations, including Indium Tin Oxide (ITO) sensor grids. In mutual
capacitance mode, the PTC requires one pin per X-line (drive line) and one
pin per Y-line (sense line). In self-capacitance mode, the PTC requires only
one pin with a Y-line driver for each self-capacitance sensor.
