Provides capacitive touch capability, adds gesture recognition to resistive screens
Freescale Semiconductor has extended Xtrinsic sensing portfolio with Xtrinsic touch sensing platform, an offering that combines gesture recognition on resistive screen technology and capacitive touch sensing in a single integrated circuit.
Xtrinsic touch sensing platform provides capacitive touch capability, adds gesture recognition to resistive screens for markets and situations and expands Freescale’s Ready Play solutions portfolio.
Freescale Ready Play offerings integrate certified application functionality, allowing customers to add features while reducing development cost, simplifying design cycles and enabling scalability in applications and systems.
The Xtrinsic touch sensing platform enables the addition of up to four capacitive electrodes to a customer’s system – all packaged in a 5×5 mm, 32-pin QFN and the platform includes standard X-Y resistive touch screen detection with optional calibration and pressure detection on resistive screens.
Gesture detection includes slide, two-touch pinch and expand, and two-touch rotate with four capacitive electrodes independent from the touch screen utilizing I2C and UART communications protocols, as well as a user-configurable screen resolution.
Freescale Industrial and Multi-Market MCU business vice-president Geoff Lees said Freescale’s Xtrinsic capacitive and resistive touch sensing platform is the first device to integrate gesture recognition without the need for complex hardware or screen modifications.
"It offers a quick and inexpensive solution for customers to develop advanced user interfaces for markets that haven’t previously incorporated touch sensing technologies and should have a strong impact on mobile health care applications, automobiles, netbooks and smart mobile devices," said Lees.
