EMBEDDED SYSTEM MICROCONTROLLERS BASICS | 8051 microcontollers

In my previous post, I've given you   an introduction about embedded system and its applications
In this post I'll be introducing you to the world of microcontrollers and the most common 8051 family microcontrollers. As I have told you that embedded system is a combination of software and hardwares. Softwares deals with the task and flexibilites a system does and hardware part deals with the microcontrollers.

MICROCONTROLLERS IS OFTEN ASSOCIATED  AS MICROPROCCSESORS BUT THERE ARE SOME DIFFERENCES BETWEEN THEM.

In general purpose microprocessors there is no RAM, ROM, I/O PORTS, TIMERS and other peripherals
While  microcontrollers has
*A CPU (Microproceesor)
*RAM
*ROM
*I/O PORTS
*TIMER
*ADC (A TO D CONV.)   etc.

The image describes the microcontllrers and microprocessors. In general purpose microprocessors external ram,rom,i/o prts,timers and other peripherls need to be added to make them functional.
