1 Overview Consumers' expectations for home appliances are higher than ever. They need high-end products that are reliable, easy to use, and feature-rich. To meet these needs, the technology that large home appliance developers need must support the following features: 1) Advanced motor control function for safe and quiet operation 2) High-efficiency energy-saving technology, which can realize electricity measurement and control through smart metering network connection 3) Advanced human machine interface (HMI) support through touch screen technology for a rich and easy user experience 4) Flexible and compatible connectivity to integrate devices with external environments 5) Standard-based certification to support reliable, high-quality solutions 2. Advanced, high-performance solutions Atmel® offers a number of ideal solutions for a wide range of household appliances: Cooling - Power efficiency is critical to cooling equipment. To meet today's green energy requirements, refrigerators and freezers must support global energy efficiency standards and advanced smart metering system communications. Atmel®'s customizable intelligent microcontrollers offer flexible connectivity options and an energy-efficient architecture that are ideal for cooling applications. Power efficiency is critical to cooling equipment. To meet today's green energy requirements, refrigerators and freezers must support global energy efficiency standards and advanced smart metering system communications. Atmel®'s customizable intelligent microcontrollers offer flexible connectivity options and an energy-efficient architecture that are ideal for cooling applications. Cooking — Cooking appliances (such as stoves, microwave ovens, and ovens) typically require temperature sensors, mass sensors, programmable timers, and complex motor controls to support the operation of fans and other equipment. Some cooking appliances have remote control functions, and the full-featured, responsive touch interface is the key to ensuring ease of use. Atmel®'s industry-leading touch solutions and customizable microcontrollers are ideal for cooking appliances. Cleaning — The washing machine needs to support motor control, water level and temperature sensing, and user interface components that can withstand harsh environments. For home appliances to be connected to the home network, a standards-based secure connection is also required. Atmel® offers a wide range of microcontroller and touchscreen solutions to support today's advanced cleaning equipment. Motor Control — Microcontrollers are becoming more common in motor control applications and are gradually replacing proprietary standard products (ASSPs) and application-specific integrated circuits. Because the microcontroller is equipped with embedded peripherals, it is more flexible and less expensive than other solutions. Safety-critical touch interface — The Atmel® QTouch® security platform reduces the development cycle of safety-critical appliances to a maximum of 12 months, adding mandatory security to home-based capacitive touch-enabled user interfaces. 3. Atmel QTouch technology for home appliances The Atmel® QTouch security platform reduces the development cycle of safety-critical appliances to a maximum of 12 months, adding mandatory security to home-based capacitive touch-enabled user interfaces. The Atmel QTouch Safety Platform is pre-certified with VDE/UL 60730 and 60335 Class B certification, enabling home equipment designers to focus on developing capacitive touch buttons, sliders and scroll wheels on Atmel | SMART ARM Cortex M0+ based MCUs. An innovative, easy-to-use interface, rather than spending effort on security authentication. With the dynamic hardware and firmware noise filtering that has passed the IEC61000-4-6 10V conducted immunity test, the QTouch safety platform ensures excellent noise immunity with minimal design effort. In addition, it offers FMEA support and excellent moisture resistance. The platform currently supports all Atmel│SMART SAM D20 ARM® CortexTM-M0+ MCUs. Key characteristics 1) QTouch Safety Library with IEC 61000-4-6 10V Conducted Immunity Test 2) QTouch Safety Library certified to IEC/UL 60730 and 60335 Class B 3) Advanced noise reduction and moisture resistance measures – can be adjusted for any environmental conditions 4) FMEA support 5) Fast response time Power efficiency is critical to cooling equipment. To meet today's green energy requirements, refrigerators and freezers must support global energy efficiency standards and advanced smart metering system communications. Atmel®'s customizable intelligent microcontrollers offer flexible connectivity options and an energy-efficient architecture that are ideal for cooling applications. Features and advantages A variety of 8- and 32-bit microcontrollers dedicated to motor control, supporting brushless DC motors, AC motors and switched reluctance motors. The Atmel solution meets energy efficiency requirements such as Energy Star and European specifications to provide maximum efficiency. Atmel offers the IEC 60730 Class B library to support customers during the certification process, greatly accelerating time to market. The Atmel 32-bit AVR microcontrollers feature a multi-layer data bus and DMA controller, making them ideal for HMI applications that require high bandwidth. With the powerful touch sensor technology of the Atmel QTouch® library, designers can add capacitive touch buttons, pulleys and sliders at no additional cost. The Atmel megaAVR® and Atmel TInyAVR® microcontrollers support a local voltage of 5 volts. Highly integrated solutions such as motor control and single-chip HMI touch help reduce BOM. ZigBee PRO compatibility enables standards-compliant connectivity and smart metering. The node verification feature supports smart metering infrastructure connectivity. 4. Solution main components
