mTouch™ Sensing Solutions

Supported 8-bit & 16-bit Architectures: PIC® Microcontrollers

Touch sensing has become an alternative to traditional pushbutton switch user interfaces. It requires no mechanical movement and enables modern-looking design. Touch sensing is expanding beyond the consumer market and is taking hold in medical, industrial and automotive applications because of aesthetics, flexibility, maintenance, cost and cleanliness.

Microchip’s mTouch technology offers a wide variety of solutions for keys and sliders as well as turnkey touch screen controllers. These are easy to implement, consume extremely low power and are offered in small packages.

mTouch Technology provides a free and easy method for designers to add touch sensing keys to applications utilizing PIC® MCUs. Being a source-code solution further helps engineers quickly integrate touch sensing functionality with their existing application code in a single, standard microcontroller, thus reducing the total system cost associated with current solutions.
