Welcome to our new course on 8051 Microcontroller

Course topics

1) Introduction to 8051 Microcontroller

You will learn the basics of a microcontroller and how is it different from a microprocessor. You will be introduced to the various aspects of 8051 processor, its internal RAM and ROM, and its I/O components along with their practical implementation.

2) Pin Diagram of 8051

You will get a detailed explanation of every pin of 8051. Right from its clock input, its power supply, address-data bus, control signals, timer inputs, serial port, parallel ports etc.

3) Architecture of 8051

You will get a comprehensive explanation of the architecture, ALU, data registers, address registers, internal memory addresses, flag register, I/O port latches etc.

4) PSW – Flag Register

Every flag with its use and effect by arithmetic and logic operations. Deep insights into signed and unsigned number systems, RAM banks and signed overflow. Umpteen numerical examples will be discussued to make the concept crystal clear for you.

5) Memory Organization (ROM)

8051 can work with only internal ROM, only external ROM or even both. You will learn how to configure the system in each of these options.

6) Internal RAM organization

Detailed understanding of the internal RAM, its register banks, bit addressable area, general purpose area and stack implementation.

7) SFRs – Special Function Registers

You will learn what addresses are allotted to SFRs and the amazing reasons behind them. You will also learn the bit addresses of the SFRs.

8) Your next step…

Your next step will be to move into learning addressing modes of 8051 and subsequently dive into the vast instruction set. The more you understand instructions, the better you will write programs of 8051 microcontroller.
