What is the basic construction of microcontroller?

Question

i want to know all the things about microcontroller. i am b.tech 2nd year student of instrumentation & control from jss mahavidyapeetha,noida.

Answer 1

microcontroller consist of only these part;

1. CPU

2. Ram

3. Rom

4. I/O

5. Alu

6. Timer

i will explain based on Intel 8051( the most popular microC).

u design the program/coding/instruction by using notepad,

then u hv to assemble the notepad with is save in .asm extension. there are many assembler that u can use. i use merlin/ easy 68k...after the notepad assemble, it will produce .hex and .lst file. the hex file will be downloded into the microC, the .lst file is use to debug if theres any error.

run your microC to see the result.

Answer 2

If you want to know all the things about a microcontroller than you are going to want a book or two. There are a lot of different microcontrollers from different manufactures.

You can get a good intro at

http://en.wikipedia.org/wiki/Microcontro...

There are a lot of links for more information too.

I happen to be using a PIC18F4525 you can find a datasheet here

http://ww1.microchip.com/downloads/en/De...

You can get an overview of that type of device here

a microcontroller can include (but is not limited to)

A CPU, RAM, ROM, EEPROM, Flash, ADC's, timers, USART, general purpose IO...

Some have a special unit for mutliplication

some have a built in USB interface

or a built in ethernet interface

Answer 3

Look on the internet and your library for "all the things".

Basically it is an IC that has a processor, memory and IO capabilities. It's program code is contained in programmable ROM also on the same IC.

google it, everyone here is a dummy with smartA#$ answers!
