Touch Sensors


Freescale offers designers a broad portfolio of Xtrinsic touch sensing solutions providing the best fit for HMI designs. 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.

Freescale's fourth generation Xtrinsic Touch Sensing Software Suite (TSS) 2.6, is an innovative touch sensing software that adds value to targeted Freescale Silicon. The free downloading software, in addition to its previous version TSS 2.5 now supports a larger MCU portfolio including the new HCS08 PT family and two new 90nm families: ARM®Cortex™-M4 Kinetis MCUs and ColdFire+.

MCU-Based Capacitive Touch-Sensing 
(3:18) The Touch-sensing interface panel for appliances provides sleek controls. The second consists of a metal cap design over the electrodes to detect capacitive changes. The third is an inductive cooker that radiates electromagnetic fields that translate to heat.
