 Touch Sensing


 
Freescale has a broad portfolio of hardware and software touch sensing solutions help you choose the best fit for your design. Touch sensing technology can reliably replace mechanical buttons and switches to eliminate mechanical wear and tear. Freescale touch sensors can be configured into simple sliders, rotary wheels and touch pads to offer significant advantages for more intuitive user interfaces, allowing greater freedom for designers while reducing overall system cost.
