Microchip Technology has launched its AVR EB family of MCUs to provide a solution for addressing NVH and efficiency in various cost-sensitive applications.
AVR EB MCUs can alter speed, timing and waveform shape – creating sinusoidal and trapezoidal waveforms – to enhance the smoothness of motor operations, lower noise, and increase efficiency at high speeds. With near-zero latency, these adjustments can be made on the fly, employing the AVR EB MCU's unique set of on-chip peripherals that allow multiple functions with minimal programming. The result is reduced code complexity, faster response to changes in operating conditions and lower overall BOM cost since several tasks, such as reading environmental sensors and serial communication, can be performed independently of the CPU. Also, the devices' small form factor (as small as 3mm x 3mm) allows them to be mounted directly to the motor for a compact control solution.
"Many of the problems observed in a wide range of devices, from automotive seat motors to cooling fans in data servers, are caused by a low-quality, low-cost controller that can't reliably reduce vibration and smooth motor function," said Greg Robinson, corporate vice president of Microchip's 8-bit MCU business unit. "The AVR EB family of MCUs can increase system smoothness and energy efficiency without resorting to a higher-cost control solution."
The AVR EB family of MCUs is fully supported in the company's MPLAB Development Ecosystem and is being introduced with a new Curiosity Nano Development Board to support rapid prototyping. The AVR16EB32 Curiosity Nano Evaluation Kit (EV73J36A) connects seamlessly to MPLAB X, Microchip Studio and IAR Embedded Workbench IDEs. MCC Melody – an intuitive, web-based graphical configuration tool – can also help lower development time.
