What are the Differentiating Features of AVR and ARM Microcontrollers?


A microcontroller is an integrated circuit (IC) useful in controlling other portions of an electronic system. Usually by a microprocessor unit (MPU), memory, and some other peripherals. These devices usually optimize for different embedded applications. That requires both processing functionality and agile, responsive interaction with digital, analog, or even electromechanical components. However, the most common way to refer to this category of integrated circuits is as “microcontroller”. “Microcontroller” is a well-chosen name as it emphasizes defining characteristics of the specific product category. Further, its different functionality comes by combining a digital processor and digital memory with additional hardware. That is basically designed to help the microcontroller interact with different other components.

Introduction to ARM Microcontrollers

The ARM microcontroller is the most commonly in use controller in different types of embedded projects and in different types of industrial projects. It is basically useful due to its advantages over other controllers and modern structures. Owing to less cost and better operation, it is moreover useful in different types of projects. Like, as the different categories of control systems, wireless circuits, sensing devices, and different automobiles. Looking at the widespread usage of this microcontroller, you can take a brief training to get a better understanding of its application. You can go through ARM Microcontroller Training in Noida for building a strong grasp of this microcontroller. In this controller, there is a memory of different types of central processing units, and is based on RISC. However, it is mostly available in thirty-two-bit and sixty-four-bit configurations. 

Features of ARM Microcontroller

# Its board comprises a thirty-two-bit central processing unit which is certainly of high speed.

# It comes with a three-stage pipeline.

# This board makes use of the thumb 2 technique.

# This module is compatible with different other types of tools and RTOS.

# It is even compatible with the sleep mode of operation.

# It provides the ability to control multiple types of software

APPLICATIONS of ARM microcontrollers

# ARM microcontrollers are indeed useful in space and aerospace technologies.

# It is also helpful in different medical equipment such as MRI, CT scanners, ultrasound, and implantable devices.

# Also useful at the research level in particle accelerators, nuclear reactors, and even X-ray cargo scanning applications.


An advanced version of a microcomputer that integrates into a tiny chip is known as the AVR microcontroller. This microcontroller mostly includes a processor, programmable I/O peripherals & memory. The AVR microcontroller provides digital control over different kinds of electrical, automotive, or mechanical systems, industrial plants, various devices, electronic gadgets, etc. You can learn with AVR Microcontroller Training in Delhi for building a strong foundation of its architecture. And further, work efficiently on implementing this microcontroller in different appliances. These microcontrollers are generally available in sizes of 8, 16, and 32-bit ICs. However, the most widely in use AVR microcontrollers are; ATmega8, ATmega16, ATmega32 & ATmega328 microcontrollers.

AVR Microcontrollers are typically available in 3 categories like TinyAVR, MegaAVR & XmegaAVR.

TinyAVR microcontrollers are available in small sizes, however, offer less memory & opt for only simpler applications.

MegaAVR microcontrollers are indeed very famous owing to their capacity of 256 KB of memory. It further includes a maximum number of peripherals & is useful in moderate to complex-based applications.

XmegaAVR is majorly in use for complex applications where high speed & large program memory is necessary.

  • Flash memory is 16KB. and SRAM is 1KB.
  • 10-bit •8-Channel ADC.
  • EPROM comes with 512 Bytes.
  • Offers ISP or In-System Programmer.
  • Serial USART.
  • DIP package.
  • 16-bit Timer or Counter -1.
  • 8-bit Timers or Counters -2.
  • Digital to Analog Comparator.
  • Master or slave SPI serial interface.
  • SPI Interface.
  • It is available in 40-Pin.
  • PWM Channels -4.
  • Programmable serial USART.

Applications of AVR Microcontroller

  • AVR microcontroller is useful in an embedded system for the operation of high-speed signal processing.
  • These microcontrollers are useful in touch screens, home automation, medical devices, defense, automobiles, and more.


Owing to your specific needs and requirements you can use the most appropriate microcontrollers. Whether you are looking for less cost, optimized storage, or even digital coverage, microcontrollers have them all for you.
