Difference Between Arduino and 8051 Microcontroller (With Table)

Microcontrollers are the integrated circuits that used to control the other important parts of the electronic system, while there are other microprocessors are the units that implement all the processors’ functionality by a single unit. They are low-cost, small, and works as an individual working system. A microcontroller comprises a memory unit, central processing unit, and peripherals.

Arduino vs 8051 Microcontroller

The difference between Arduino and 8051 Microcontroller is that the Arduino is not one of the microcontrollers but is a complete board with its IDE, and it comes with already tested hardware and software libraries. While comparatively, on the other hand, the 8051 Microcontroller is defined as the whole family of numbers ranging from 8031 to 8751 of 8-bit microcontrollers.

Arduino to be defined as not a microcontroller but actually, a microcontroller board with an integrated development environment (IDE) and also that comes with already tested hardware and software libraries. It comes with three major components – Arduino board, Arduino IDE, and external hardware. With all these components together, one can program the device to perform anything like controlling the lights, motors, or read sensors.

8051 Microcontroller can be defined as the family of the numbers ranging between 8031 and 8751 of the 8-bits microcontrollers. It is one of the popular and widespread used microcontrollers in the market. The 8051-family of the microcontrollers were introduced by the Intel Corporation company. After the introduction of microcontrollers in the market, it has become the basis of thousands of electronic products.

What is Arduino?

Arduino is widely mistaken as the microcontroller, whereas, in reality, it is a microcontroller board with its integrated development environment (IDE), and along with that, it comes with the pre-tested libraries of software and hardware. The integrated development environment (IDE) present on the Arduino is referred to as ‘Arduino IDE’ and is one of the parts of the three major comprising component along with Arduino board and external hardware.

Arduino was developed by some graduated students at the Interaction Design Institute Ivrea (IDII) in the year 2003. The AVR microcontroller is the base, and the board is built around it. The power supply required for the Arduino ranges from about 6 volts to 20 volts, and it is recommended to use the power supply in between 7 volts to 12 volts maximum.

The clock speed of the Arduino is about 16 MHz, and that can be extended up to the speed of 20 MHz. The complete one-machine cycle is equal to the one complete clock cycle. Also, there are many supported ad-ons available in the market that provides strong support.

What is 8051 Microcontroller?

The microcontroller that has been developed by the very famous Intel Corporation Company in the year 1980. The 8051 Microcontroller can be easily stated or defined as one of the members of the 8-bits microcontroller family that ranges in number between 8031 to 8751. It is widely popular across the globe and is used for quite a number of reasons.

8051 Microcontroller sometimes can be heard referring to as the ‘system on a chip’ because of the presence of 128 bytes of RAM, 1 serial port, 2 timers, 4K byte of ROM, and 4 ports. The power supply required for the Microcontroller ranges between 5 volts to 6.6 volts. The clock speed of the system is 12 MHz, and the 12 complete clock cycles are equal to one complete machine cycle.

For 8051 Microcontroller, the Keil Uvision IDE programming is used that writes, compiles, and uploads the code. Also, in the market, there are many available supporting development kits, but unfortunately, the support provided by them is very poor. They are used in automated machines like- home appliances, remote controls, toys, etc.

Main Differences Between Arduino and 8051 Microcontroller

  1. Arduino is not a microcontroller but a complete microcontroller board with its IDE and comes with before-tested hardware and software libraries, whereas comparatively, on the other hand, the 8051 microcontrollers are defined as the microcontroller that belongs to the family of the number ranging between 8031 to 8751 of the 8-bits microcontroller.
  2. The power supply required for the Arduino is about ranging in between 5 volts to 20 volts wherein the minimum volts used are 7 volts, and the maximum range goes up to 12 volts, whereas comparatively, on the other hand, the power supply requirement of the 8051 microcontroller ranges from 5 volts to 6.6 volts.  
  3. The Arduino was developed at the Interactive Design Institute Ivrea (IDII) in Italy in the year 2003 by some graduate students, whereas comparatively, on the other hand, 8051 microcontrollers were developed by the very famous Intel Corporation Company in the year 1980. 
  4. The clock speed of the Arduino is about 16 MHz that can be extended up to 20 MHz, whereas, on the other hand, the clock speed of the 8051 microcontrollers is about 12 MHz. 
  5. For the Arduino, the one complete machine cycle is equal to the one clock cycle, whereas comparatively, on the other hand, for the 8051 microcontrollers, the one complete machine cycle is equal to the 12 clock cycles. 
  6. For Arduino, the Arduino Ide is used as the program that helps in write, compile and upload the code, whereas comparatively, on the other hand, for the 8051 microcontrollers, the Kiel Uvision IDE is used to write, compile, and uploading of the code. 
  7. In the market, there are many support ad-ons available for the Arduino, and they provide strong support, whereas comparatively, on the other hand, the support ad-ons available for the 8051 microcontrollers do not provide strong support.  

Conclusion

In closing, the Arduino that is mistaken to be a microcontroller is, in reality, a microcontroller board with an integrated development environment (IDE) that comes up with the pre-tested software and hardware libraries. Arduino comes up with its three major components that are – Arduino board, Arduino IDE, and external hardware. They are used in home automation systems, lightening systems in games or gardening, some innovative robotic appliances, etc.

In contrast, the 8051 Microcontroller one of the microcontrollers that belong to the family number ranging between the 8031 to 8751 of the 8-bits microcontrollers. They are very popular in the market and do have widespread use. These are largely used in automated systems like – remote controls, toys, appliances, and many more other things.
