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
Home appliance OEMs are now expected to develop goods that automatically shut down if a fault is detected within the system. The certifications that call for this stringent level of safety—IEC/EN 60730—cover mechanical, electrical, electronic, EMC, and abnormal operation of appliances.
By designing with Atmel® QTouch® capacitive touch controllers for button, slider and wheel capability—which are certified-ready devices—manufacturers can now more easily design household appliances that meet these certifications. One of our newest certified devices, the Atmel AT42QT1481, provides a high button count at low cost, along with the flexibility to construct button sensors in a variety of shapes and sizes. Our certified devices - combined with superior Atmel conducted immunity (CI) - makes Atmel the leading capacitive touch supplier for all home appliance user interfaces.
- Hardware Benefits — POR, BOD, CI, RAM, Flash, EEPROM, WDT, ADC, clock, and zero cross detector
- Software Benefits — Spread spectrum, software interrupts, memory tests, registers (I/O & CPU), Atmel Software Framework
- FMEA — Sequence tests running continuously in the background to detect device and interface failures
- High Button Count – Single device with high button counts capable through Atmel QMatrix® sensing algorithm
- Conducted Immunity – Great noise and EMC immunity
- Moisture Tolerant – In outdoor designs and/or environments with humidity
- AT42QT1481 – 48-button device with above feature sets
Advanced, Energy-Efficient Solutions
Atmel® offers a wide range of solutions that are ideal for a variety of household appliances:
- Refrigeration — Power efficiency is key for refrigeration equipment. To meet today's green energy requirements, refrigerators and freezers must include support for global efficiency standards, as well as advanced communications for smart metering. The Atmel® intelligent, customizable microcontrollers provide flexible connectivity options and power efficient architectures that are an excellent fit for refrigeration applications.
- Cooking — Cooking appliances such as stoves, microwave ovens, and conventional ovens, often require a combination of temperature and mass sensors, programmable timers, and sophisticated motor control for fan and other devices. Some include remote controls, and rich, responsive touch control interfaces are key for ease of use. Atmel® industry leading touch solutions and customizable microcontrollers are ideal for cooking appliances.
- Washing — Washing machines require support for motor controls, water level and temperature sensing, and user interface components that can withstand harsh environments. Standards-based, secure connectivity is also a must for appliances that will connect to a home network. Atmel® offers a rich array of microcontrollers and touch screen solutions that can power today's advanced washing equipment.
- Motor Control — Microcontrollers are more and more common in motor control applications and are replacing Application-Specific Standard Products (ASSP) and ASICs. Since microcontrollers feature embedded peripherals, they provide more flexibility and offer a better cost solution compared to other solutions.
