Ⅱ What is a Microcontroller?Ī Microcontroller is a VLSI IC that, along with some other peripherals such as memory ( RAM and ROM), I/O ports, timers/counters, communication interface, ADC, etc., contains a CPU (processor).Ī microprocessor (which was built before the microcontroller) is merely a processor (CPU) and does not have the peripherals mentioned above. So, an introduction to the 8051 microcontrollers and some of the fundamentals of the 8051 microcontrollers will be given in this article.īut before we get into the 8051 Microcontroller Introduction and Fundamentals, we need to talk a bit about what a microcontroller is and the distinction between a microprocessorand a microcontroller. While 8051 Microcontroller can seem a bit out of date, we believe that Microcontrollers, Embedded Systems, and Programming are some of the best platforms to get started with (both C and Assembly).
There are several features of the 8051 Microcontroller such as Serial Communication, Timers, Interrupts, etc., and thus many students and beginners begin their work on the 8051 Microcontroller principle of Microcontrollers (although this trend seems to be changed with the introduction of Arduino). In differen t fields, such as embedded systems, consumer electronics, vehicles, etc., the 8051 Microcontroller is one of the most prominent and most commonly used microcontrollers. The 8051 microcontroller series, technically referred to as the Intel MCS-51 Architecture, was developed by Intel in 1980 and was very popular in the 80's (still are popular).
