Broadening the Atmel | SMART Portfolio of Capacitive Touch Buttons, Sliders and Wheels, New Devices Shorten Development Cycle for Safety Critical Home Appliance Products by Up to 12 Months
Atmel® Corporation (Nasdaq: ATML), a leader in microcontroller (MCU) and capacitive touch solutions, today announced the new QTouch® safety platform for capacitive touch-enabled user interfaces in the home appliance market. The new QTouch safety platform adds mandatory safety and supports the Atmel | SMART ARM® Cortex®-M0+ based MCUs for safety critical home appliance applications.
The most recent QTouch capacitive touch platform is based on the Atmel | SMART SAM D20 integrating an on-chip peripheral touch controller (PTC) to deliver excellent EMC robustness, short response times and combines self- and mutual capacitance sensors for up to 256 channels. The QTouch platform has been widely adopted by the world's leading home appliance manufacturers.
With today's home appliance, designers are facing stringent certification requirements for safety and EMC robustness. Designers are looking for a platform that supports all the applicable safety standards required to pass end product qualification with minimal design time. Atmel's QTouch Safety Platform is pre-qualified for the VDE/UL 60730 Class B and UL 1998 certifications, reducing a designer's overall development time by as much as twelve months. Household appliance designers can now focus on more innovative, easy-to-use interfaces that support capacitive touch buttons, sliders and wheels on an Atmel | SMART ARM Cortex M0+-based MCU rather than focusing on safety certification features. The SAM D20 ARM-based Cortex M0+-based MCU is the first device to support the QTouch safety library. Support for future home appliance devices will be added as they become available.
Designers can download the QTouch Safety Library Firmware, FMEA library and QTouch Composer Development Software on an Atmel ARM Cortex M0+-based MCU. The QTouch Safety Library ensures excellent noise tolerance through dynamic hardware and firmware noise filtering through the IEC 61000-4-6 10V conducted immunity with minimal design effort. Additionally, QTouch Safety Platform provides FMEA support and moisture tolerance.
"With the increased regulations in Europe and the US for safer home appliance products, designers are looking for pre-qualified solutions that accelerate this part of the development cycle," said Geir Kjosavik, director of QTouch product marketing, Atmel Corporation. "Atmel's latest QTouch Safety Platform gives designers the pre-qualified features for their home appliances while enabling them to differentiate their products with capacitive touch interfaces in the form of buttons, wheels or sliders. We are excited to help bring more safety critical home appliances to market and are continuing to broaden our portfolio of devices to support the home appliance market."
