Freescale Touch Sensing Software Suite enables any 8-Bit S08 MCU as a touchsensor, providing cost effective and flexible solutions for Human Machine Interfaces.

Quick and Easy

Touch Sensing Software Suite Key Advantages

TSS simplifies user interface designs, enabling customers to develop an application within 10minutes from scratch.

Innovative and Reliable

Complementary & Green

TSS is complementary software with low cost development tools, allowing the designer to choosethe best MCU device for their application, and saving them the cost of an extra IC sensor.

TSS provides an evolution in user interfaces that avoid mechanical wear and tear, increases thelife time of products, and gives greater flexibility to designers by using the awarded FreescaleMCU portfolio.
