Frequently Asked Questions

What are Microcontrollers?

MCUs (microcontroller units), another name for embedded semiconductor devices utilized in circuit board design, are microcontrollers. They effectively function as a computer inside an integrated circuit (IC). Microcontrollers are typically used in embedded applications with a single function, unlike microprocessors, which are made for general-purpose work in Personal Computers, Tablets, and Smartphones. The slower-than-average non-volatile Flash program memory of microcontrollers prevents them from operating at the same clock speed as microprocessors.

How Microcontrollers Work?

The microcontroller module resembles a little computer on a chip. It manages a device’s operations by analyzing the data it receives from peripherals. Peripherals help with information intake and output, in case you are unfamiliar with the term. An image scanner or graphics card are two examples of peripherals.

The microprocessors embedded in apple use the data added to its data storage and information obtained from the microcontroller to generate actions. Let’s look at a video game controller to show how a microcontroller functions. The microcontroller receives input from the player when they press a button to choose an option in their game, and it uses that information to carry out the desired action—selecting the option. Consider it this way: A microcontroller is most likely embedded in any electronic device interacting with a system to control it and perform subsequent actions.

What are Microcontrollers made up of?

Microcontrollers come with memory, I/O peripherals, and one or more processors. Timer devices, ADCs (analog-to-digital converters), and DACs are some of these peripherals.

What does 8-bit mean?

The data bus width indicates the number of data microcontrollers can process simultaneously. For instance, a microcontroller with 8 bits can handle 8 bits at once. 8-bit, 16-bit and 32-bit MCUs are standard data bus widths.

What packages are available for Microcontrollers?

Standard chip packaging with a range of pin counts is available for MCUs. Package kinds consist of:

  • LQFP
  • QFN
  • SOIC
  • IDP
  • SSOP
  • TQFP

What are ARM processor cores?

An ARM microprocessor core is frequently seen in microcontrollers. Other companies use the ARM architecture, which was developed by ARM Holdings, to make things like System-on-Chip and microprocessors (SoCs).

Where are microcontrollers used?

MCUs can be found in a wide range of technologies. They are likely to be present in any electronic device with a sensor, a display, a user interface, and a programmable output control or actuator. The following places are where you can find them:

  • computers
  • Automation
  • Medical equipment
  • Automotive
  • Robotics
  • home appliances
  • IoT-devices
