What is Microcontrollers and Embedded processors?
In this portion we talk about the need for microcontrollers and difference them with general-purpose microprocessors such as the Pentium and x86 microprocessors. We also look at the bit part of microcontrollers in the embedded market. In addition, we issue some basis on how to choose a microcontroller.

Microcontroller versus general-purpose microprocessor
What is the differentiation between a microprocessor and microcontroller? These microprocessors contain no RAM, no ROM and no I/O ports on the fragment itself. For this reason, they are often mentioning to as general-purpose microprocessors.
Microcontroller for embedded systems
In the writing debate microprocessors, we frequently see the term embedded system. Microprocessors and microcontrollers are interval between used in embedded system fruit. An embedded outcome uses a microprocessor or microcontroller to do one duty and one duty only. A printer is a sample of embedded system for the cause that the processors inside it execute only one duty, getting the data and printing it. Difference this with a Pentium-based PC (or any x86 IBM-compatible PC). A PC can be used for any number of appeals such as word processor, video game player, bank teller terminal, print server, network server, or internet terminal.
Some Embedded products using microcontrollers such as Home Appliances, intercom, telephones, security systems, camcorder, remote controls, video games, cellular phones, pinball machines, toys and exercise equipment, garage door openers, answering machines, musical instruments, sewing machines, lighting control, paging, camera, fax machines, home computers, TVs, cable TV tuner, VCR.
Choosing a microcontroller
There are four utmost 8-bit microcontrollers. They are: Zilog’s Z8, Intel’s 8051, Freescale’s 6811, and PIC 16X from microchip Technology. Each of these microcontrollers has an especial command set and register set; therefore, they are not conflict with each other. Plan of action written for one will not run on the others. There are also 16-bit and 32-bit microcontroller’s ways by various chip makers. Three level in select microcontrollers are as follows: 1. Meeting the operation of computers needs of the task at hand efficiently and cost successfully, 2. Freedom to do something of software development tools such as assemblers, compilers, and debuggers, and 3. vast availability and dependable source of the microcontroller.
