Xtrinsic touch sensing software 2.6 offers highly accurate touch detection for Freescale microcontrollers

New software enables robust touch-sensing performance for Kinetis, S08 and ColdFire+ microcontrollers for consumer, industrial and medical applications

AUSTIN, Texas – Jan. 24, 2012 – Freescale Semiconductor (NYSE: FSL) continues to help make touch-sensing application development easier and faster with its touch sensing software (TSS), a software library with a set of development tools that adds touch functionality to Freescale microcontrollers (MCUs). The latest version (TSS 2.6) adds robustness and support for an S08 8-bit MCU family and two 90 nanometer ColdFire+ and Kinetis 32-bit MCU families.

Freescale’s MCU-based TSS 2.6 is complimentary licensed software that allows customers to incorporate human machine interfaces (HMIs) into next-generation designs without increasing system cost. The TSS 2.6 addition to the Xtrinsic sensing portfolio allows integration of touch sensing capabilities for consumer electronics, multimedia Internet devices, medical and industrial equipment and home appliances.

Advantages of TSS 2.6

  • Touch detection algorithm for reduced false touches with electrical noise

Greater flexibility for product designers to select from more than 1,000 MCUs within Freescale's broad 8-bit to 32-bit portfolio

  • Reliable touch detection using the touch sensing input (TSI) module provides extremely high sensitivity
    • Modern upgrade from mechanical to touch-activated push-button, slider and rotary user interfaces
    • Flexible, low maintenance and supports a variety of sensitivity levels and overlay surfaces
    • Functional in low-power modes, with wake-up via touch
    • Low-power mode current consumption adder of one to three micro amps
    • Up to 16 electrodes using a single pin per electrode, with no external component requirements
    • High sensitivity – capacitance measurement resolution down to 0.02 fF
  • User interface controllers manage multiple keypad layout configurations
  • Simplifies user interface designs, enabling customers to develop an application within minutes using a broad range of tools and demonstration software
  • Reduces overall system cost by simplifying mechanical design and assembly

Enhances reliability by replacing mechanical button wear and tear, increasing device longevity

Pricing and availability
Xtrinsic touch sensing software 2.6 provides a cost-effective, comprehensive solution through complimentary software licenses and cost effective development tools. The new TSS 2.6 version is planned for availability in Q2 2012.

Freescale touch sensing software tools include:

  • ColdFire+ TWR-MCF51QM ($69 USD) and TWR-MCF51JF ($79 USD)
  • Kinetis TWR-K40X256-KIT ($69 USD), TWR-K60N512-KIT ($69 USD), TWR-K53N512-KIT ($109 USD) and KWIKSTIK-K40 ($35 USD)
