Reliable, Robust Operation
More than ever, consumers have high expectations for home appliances. They demand sophisticated, feature-rich products that are reliable and easy to use. To meet these needs, developers of white goods need technology that provides:
- Advanced motor control features for safe, quiet operation
- Green, power-efficient technology, as well as energy measurement and control through connectivity with smart metering networks
- Advanced human machine interface (HMI) support through touchscreen technology for a rich, easy user experience
- Flexible, compatible connectivity to integrate devices with the outside world
- Standards-based certification to enable reliable, high-quality solutions
Atmel QTouch Technology for Home Appliances
Shortening development of safety critical home appliance products up to twelve months, the QTouch Safety Platform from Atmel® adds mandatory safety for capacitive touch-enabled user interfaces for home appliances.
Atmel's QTouch Safety Platform is pre-qualified for the VDE/UL 60730 and 60335 Class B certifications enabling household appliance designers to focus on more innovative, easy-to-use interfaces that support capacitive touch button, slider and wheels on an Atmel | SMART ARM Cortex M0+-based MCU rather than focusing on safety certification features.
The QTouch Safety Platform ensures excellent noise tolerance through dynamic hardware and firmware noise filtering passing IEC61000- 4-6 10V conducted immunity with very little design effort. In addition, it provides FMEA support and moisture tolerance.
Offering easy-to-use software and hardware tools, the QTouch Safety Library firmware and QTouch Composer Development Software can be downloaded free of charge from the Atmel Gallery.
The platform currently supports any Atmel│SMART SAM D20 ARM® Cortex™-M0+ MCU.
- IEC 61000-4-6 10V Conducted Immunity tolerant QTouch Safety Library
- IEC/UL 60730 and 60335 Class B certified QTouch Safety Library
- Advanced noise and moisture countermeasures – adjustable for any environmental conditions
- FMEA support
- Fast response time
