New Update

Freescale Semiconductor upgrades Xtrinsic touch-sensing software (TSS) portfolio for next generation human-machine interface. It has included new features such as 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 in industrial, medical, consumer and auto infotainment applications, said a press note.

“The latest release of our touch-sensing software comes with feature-rich updates that provide robust functionality for more of Freescale's microcontrollers,” said Geoff Lees, vice president and general manager of Freescale's Industrial & Multi-Market MCU business.

"Reliable touch detection provides extremely high sensitivity with very low capacitance measurement resolution, offering a highly accurate and robust solution. With TSS 3.0, the user can 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," added the note.
