Freescale adds MCU functionality to TSS portfolio

TEXAS, USA: Without increasing system cost, Freescale semiconductor adds MCU functionality to its Xtrinsic touch sensing software (TSS) portfolio.

It has included some more features that includes water tolerance, noise detection and a touch-detection algorithm for reduced false touches under electrical noise.

TSS 3.0 is the latest addition to Freescale's growing portfolio of touch-sensing software for button replacement. It targets applications in industrial, medical, consumer and auto infotainment industries.

With simplified user interfaces, customers can now develop an application within minutes using a broad range of tools and demonstration software with reduced effort and minimised cost.

Through its reliable touch detection, it provides high sensitivity with very low capacitance measurement resolution, offering a highly accurate and robust solution. TSS 3.0 helps the user define the sensitivity level, or auto-sensitivity calibration (ASC) will do it based on noise level analysis.

TSS 3.0 is immune to droplets of water and able to distinguish touch on the electrodes even when the electrodes are covered with a water film.
