Get Started

We'll tell you all you need to know to start evaluating and working with this product.

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.

Features and Benefits

  • Atmel offers a wide range of 8- and 32-bit microcontrollers that are dedicated to motor control, providing support for BLDC motors, AC motors, and switched reluctance motors.
  • Atmel AVR® 32-bit microcontrollers embed a digital signal processor (DSP) and a floating point unit (FPU) in select models, to deliver the high performance required in advanced motor control solutions.
  • Many AVR microcontrollers include high-end PWM modules with dead-time insertion, fault management, synchronization with analog, making them a perfect choice for motor control.
  • AVR microcontrollers are offered in 105°C versions, as well as models up to 150°C, for a perfect match for washers with challenging temperature requirements.
  • Atmel provides an IEC 60730 Class B Library to support customers in the certification process, which dramatically speeds time to market.
  • Atmel AVR 32-bit microcontrollers feature a multi-layer databus and DMA controller that make them a perfect fit for HMI applications where high bandwidth is required.
  • Atmel has the industry's most robust touch sensor technology. With our Atmel QTouch® library, designers can add capacitive touch buttons, wheels and sliders at no additional cost.
  • Native 5V support is available on the Atmel megaAVR® and Atmel tinyAVR® microcontrollers. Many AVR 32-bit microcontrollers also offer 5V-tolerant inputs.
  • High integration solutions, such as motor control and HMI touch in a Single-chip, and high power IOs that can directly drive LEDs and buzzers, help reduce BOM.
  • ZigBee PRO compatibility enables standards-compliant connectivity and smart metering.
  • Node authentication capability supports smart meter infrastructure connections.
