New Microchip MCU Family Tackles System Noise, Vibration, and Harshness

Microchip’s newest MCUs include advanced timer/counter modules to streamline motor control, predictive maintenance, home automation, and more.

In an effort to reduce problems caused by noise, vibration, and harshness (NVH), Microchip has launched a new MCU family, AVR EB, targeting high-precision BLDC motor control. These devices are designed to remove the sources of noise and vibration entirely for more efficient motor control.

This article takes a closer look at the family's specs to get a sense of how the AVR EB family accomplishes NVH reduction for such control. We'll also examine the other peripherals of the MCUs to determine where an AVR EB MCU could be useful in various motor designs.

Smoother Motor Control

BLDC motors afford a high degree of control, allowing designers to reduce the impacts of NVH on device longevity. This advanced control, however, typically requires designers to develop complex control algorithms and waveform designs.

To remove the complexity associated with BLDC motors, Microchip’s AVR EB family of MCUs incorporates speed, timing, and waveform control in a single chip, allowing designers to simplify the control process and further reduce NVH impacts in sensitive applications. In addition, the onboard processor supports more complex interaction with the entire system.

Hands-Free Event Handling

The AVR EB family (datasheet linked) includes a 20-MHz AVR CPU with 16 KB flash memory and 2 KB SRAM. Complementing the devices' motor driving performance is a 12-bit ADC with 300 kilo-samples per second (kSps). The 24-bit Timer/Counter F (TCF) joins the 16-bit Timer/Counter E to provide multiple options for waveform generation and event triggering.

Smaller, Smarter Motors

The benefits of the AVR EB family combined with the small size make it useful for applications where space is constrained, allowing engineers to leverage the benefits of BLDC motors without needing bulky or power-hungry controllers. As a result, the AVR EB family may not only improve the performance of BLDC motors currently in products but also allow BLDC motors to be used in a wider variety of applications.

The reported performance of the AVR EB family and the incorporation of more peripherals may not only better automate advanced motor control but also allow designers to minimize the impacts of moving parts in solid-state systems.
