Chapter 2.0 - Breadboard Microcontroller 8051 Mounting and Led Blinking-Theory

We hope that you have successfully implemented the breadboard power stage. If not first finish up with the power stage since, it is the key step for learning 8051 on breadboard. Now the next step is to mount a p89v51rd2 or any other 8051 family based microcontroller on the breadboard. To begin with this chapter there are some basic concepts and key things which you need to understand. As this blog focuses more on practical skills, we are going to only provide some of the important tutorial references. Rest of the theoritical things can be easily found all over the internet.

The first thing you must know is the architecture and pin diagram of the p89v51rd2 microcontroller which is 8051 family based. Since most of the 8051 microcontrollers are almost have same architecture and pin diagram, it could be taken as global reference.

Pinout of 8051 Micrcontroller

Now, as you can see in the above figure pinout of 8051 microcontroller. Make sure you have a quick reference of the pinout in your mind. Here is the datasheet of the p89v51rd2 microcontroller. For more details on the hardware you can go through it.
