What is an ARM microcontroller?

The Arm® Cortex®-M group of processor cores is a series of cores optimized for power efficiency and deterministic operation. It is widely used in microcontrollers (MCUs) and can also be found embedded into multi-core microprocessors (MPUs). ST, an early adopter of the Arm® Cortex®-M cores.

Where are ARM microcontrollers used?

Arm processors are used extensively in consumer electronic devices such as smartphones, tablets, wearables and other mobile devices. They're also used in a wide range of sensors and internet of things devices.

Is Arduino an ARM?

The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller.

What is the difference between microcontroller and ARM?

ARM is based on CPU architecture so we generally call it has microprocessor when placed on a chip if ARM is combined with memories (RAM and ROM) on a single chip we can call it has micro-controller it has limited memory but when coming to microprocessor RAM and ROM are connected externally speed will be more.
