Intel then released its first 16 bit microcontroller in 1982, under name MCS-96 They basically differed in support device configurations like improved memory, presence of an ADC or DAC etc. The specialty was that all these devices could be programmed using the same MCS-51 instruction sets. Global companies and giants in semiconductor industry like Microchip, Zilog, Atmel, Philips, Siemens released products under their brand name. Following the success of 8051, many other semiconductor manufacturers released microcontrollers under their own brand name but using the MCS-51 core. The most popular microcontroller 8051 belongs to the MCS-51 family of microcontrollers by Intel. Later in 1980 they released a further improved version (which is also 8 bit), under the name MCS-51. Intel first produced a microcontroller in 1976 under the name MCS-48, which was an 8 bit microcontroller. Pin Diagram :- Internal Architecture :- Program Memory Organization :- Data Memory Organization :- 8051 System Clock :- 8051 Reset Circuit Introduction Here is a Quick Access to various sections of this article:. We have a detailed article which describes the basic difference between both. Now lets talk about 8051 microcontroller in detail.īefore going further, it will be interesting for you to understand the difference between a Microprocessor and Microcontroller.

Intel 8051 is the most popular microcontroller ever produced in the world market. Unlike a microprocessor ( ex: Intel 8085), a microcontroller does not require any external interfacing of support devices.

A micro controller is an integrated circuit or a chip with a processor and other support devices like program memory, data memory, I/O ports, serial communication interface etc integrated together.
