with application code in a single microcontroller, reducing total system cost.

Microchip offers a broad portfolio of low power, low cost & flexible solutions for keys/sliders and

touch screen controllers. Get to market faster using our easy GUI-based tools, free source code

and low-cost development tools.

Touch Sensing for Keys and Sliders

• mTouch Capacitive Sensing technology

? Longer battery life with eXtreme Low

Power MCUs; Capacitive Sensing in less

than 5 ?a

? High noise immunity and low emissions

? No external components

• mTouch Inductive Sensing technology

? Use polished or brushed metal surfaces

including stainless steel and aluminum

? Sense through gloves

? Create water-proof designs

? deploy Braille-friendly interfaces

• Broad portfolio of MCUs lowers system cost:

? 8, 16 & 32-bit PIC® MCUs for Capacitive and

Inductive touch

? Integrated USB, Graphics, LCd, Irda, CaN

Touch Screen Controllers

• Fully processed touch coordinates

• Projected Capacitive technology

? Multi-touch enabling gestures

? Low cost MCU implementation
