Microcontrollers

Features of microcontrollers 

 
1.      Architectural features:
Most microcontrollers built today are based on the CISC (Complex Instruction Set Computer) platform. A typical CISC microcontroller has over 80 instructions and it is quite common for the instructions to all behave quite differently.
The main advantage of CISC architecture is that the instructions are macro-like, allowing the programmer to use one instruction in place of many simpler instructions.
 
2.     Advanced Memory features:
          a.    Electrically Erasable Programmable Read Only Memory (EEPROM):
Many microcontrollers use the economic EEPROM for smaller amount of memory that have frequently changeable data. This type of memory is relatively slow, and the number of erase/write cycles allowed in its lifetime is limited. 
          b.    FLASH (EPROM): 
Flash provides microcontrollers with a better solution than EEPROM for requirements of large amounts in non-volatile program memory. EPROM is faster and permits more erase/write cycles than EEPROM. 
 
3.      Power Management features  
A majority of microcontrollers usually support an operation of 3 - 5.5 V. As consumer goods become trendier, compact and lighter, the focus is on microcontrollers to ensure that products with less power usage are efficiently built and then used by end-users.
 
Applications
Microcontrollers are used in products that are controlled automatically.
The various products that make use of microcontrollers in our everyday life are given below:
1.    Home: Television, DVD player, Telephone, Fax machine, Cellular phones, Security systems, Camera, Sewing machine, Musical Instrument, Exercising machine, Video games, Computer, Microwave oven.  
2.       Office: Computers, Printers, Telephones, Fax machine, Security systems.

the main difference between

the main difference between microcontroller and microprocessor is the no. instructions in micro processor are more than micro controller, there is bitwise addresseble mode in microcontroller which is not in microprocessor

i totally love this theme ;-D

what about programming

what about programming

I interested with this but it

I interested with this but it is still more and more to learn about microcontroller .

realy I want answer to this quetion :

where I can see 8051 ,PIC, AVR in real life application microwae or TV is there afemose company use any

of those MC directly or under another name.

I will highly appricheated any explain.

hai i did 5*7 dot matrix

hai i did 5*7 dot matrix display with uln2003a driver using 89c51. my question is,its going on properly but the brightness is low. so how to improve the brightness of led dot matrix.

There is a huge competition

There is a huge competition among microcontroller manufacturers. Despite this choice there are few microcontroller families that are popular .

Every now and then any techno

Every now and then any techno enthusiast opens up a computer system he can automatically get to visualize some tiny microcontrollers ...

which ic are we using for avr

which ic are we using for avr microcontroller???

 

There are many tools, free

There are many tools, free and low cost demo boards available to learn about PIC microcontrollers than any other microcontrollers.

Microchip also has developer forum where we can post our queries and provide ontime support. They also share lot of demo code and demo applications which is easy to learn about embedded application development.

Things are easy with PIC!

Enjoy!

Microprocessors are misused

Microprocessors are misused to complete big and generic applications, patch a micro controller instrument only be utilized to effect a singular strain within one use

I am doing my miniproject

I am doing my miniproject using 89s52 microcontroller.can any one tell me how to save 10 numbers in continous memory?ie which instruction should I use to save these numbers.............i want to save these numbers permanantly ,can i use ram for that?

and I also want to know that whether MOV A, @A+40 will work,where  A=accumulator,       40=an internal ram address......................please reply me soon..............thanking you

 

i wnt microprocessor basics
