ATMEGA64-16AU FAQ

What is meant by AVR microcontroller?

AVR microcontroller is an electronic chip manufactured by Atmel, which has several advantages over other types of microcontroller. We can understand microcontroller by comparing it with Personal Computer (PC), which has a motherboard inside it.

 

Why do we need AVR microcontroller?

A number of factors make AVR microcontroller a good choice especially for beginner, Easy to Code: AVR were designed from ground up to allow easy and efficient programming in high level languages with a particular focus on C language.

 

Is ARM a microcontroller or microprocessor?

Technically, ARM is a microprocessor, or, more specifically, a microprocessor architecture. The thing to understand, though, is that it doesn't represent a physical microprocessor, but the design that allows to build one.

 

What is the advantages of AVR?

The advantages of mechanical AVRs, either tap changing or magnetic induction type, vary by design but generally include: Very accurate output voltage regulation. Wide choice of kVA rating, voltage and configuration. Easily applicable to outdoor application.

 

How does an AVR work?

Automatic voltage regulators (AVRs) work by stabilizing the output voltage of generators at variable loads, but can also divide the reactive load between generators that are running in parallel (voltage droop), and helps the generator respond to overloads.
