8051 Microcontrollers: An opportunity knocking door for Embedded System Developer

by Multisoft Virtual Academy Online Training & Certification

Introduction of Microcontrollers has brought revolution in the Embedded Electronics industry. Microcontroller is an integrated circuit or better called as ‘chip’ that includes a processor in it. Not only this, but it also contains other support devices like I/O ports, program memory, data memory and lot more. Microcontrollers do not need any external interfacing like in case of Microprocessors.

8051 Microcontrollers

Intel® was the first to launch the 8051 Microcontroller in the year 1980. This 8-bit Microcontroller has emerged as one of the widely used Microcontrollers leaving behind its competitors like Texas instruments, Microchip Company, Fujitsu etc. The primary aim of any microcontroller is to govern some specialized tasks and automate the functions and 8051 is known to be the best in this genre, till date.

8051 Microcontrollers gained immense popularity all over the world, as it targeted the right set of audience that accepted the product with arms wide open. The reason that 8051 Microcontrollers covered up the market within a short time span, is a very intelligent choice of configuration that aptly satisfied the needs of a big group of developers working on development of automation devices.

Other reasons for worldwide acceptance of 8051 Microcontrollers are the RAM organization, CPU operation, along with the ports that support the upgradation feature. The users can utilize all the resources of 8051 Microcontrollers that again make it top the charts in the microcontroller field.

Basic Pins:

Pins in 8051 models	Description of Pins
PIN 9	It acts as the reset pin and resets microcontroller’s internal registers.
PINS 18 & 19	8051 also has an inbuilt oscillator amplifier. A crystal is connected to these pins that provide clock pulses to the circuit.
PIN 40 and 20	Pin 40 is a VCC (runs on +5V power supply) and Pin 20 is a ground pin.
PINS 29, 30 & 31	Pin 29 is known as PSEN (program store enable) pin and it reads a byte from memory. Pin 30 is known as ALE (address latch enable) pin and operates when multiple memory chips are connected to and a single chip needs to be selected. Pin 31 is known as EA/VPP and it’s connected to ground which represents the presence of external memory.

Ports:

Ports in 8051 models	Description of Ports
PORT P1 (Pins 1 to 8)	This port is used for general I/O operations
PORT P3 (Pins 10 to 17)	This port has similar functions like port, but includes some alternative functions as well.
PORT P2 (pins 21 to 28)	When no external memory is present, this port can be used as general I/O port. But, if external memory is used, the higher address byte, i.e. addresses A8-A15 will appear on this port.
PORT P0 (pins 32 to 39)	It acts like Port when external memory is not used. Otherwise, it works as address output (A0-A7) when the ALE pin is driven high (1) or acts data output when the ALE pin is driven low (0)
PORT P10	Asynchronous communication input or Serial synchronous communication output
