• Embedded(self contained) 8 bit microcontroller
• 16 to 32 microcontroller
• Digital signal processor

FEATURES OF MORDERN MICROCONTROLLER

1. Built in monitor program
2. Built in program memory
3. Interrupts
4. Analog I/O
5. Serial I/O
6. Facility to Interface External Memory
7. Timers 

INTERNAL STRUCTURE OF MICROCONTROLLER(BLOCK DIAGRAM)

 GOOGLY: HOW DOES MICROCONTROLLER WORKS?

WELL I CANNOT GO IN DETAIL ABOUT WORKING  because it is a vast topic in itself. I can just give you a overview-

Microcontroller consist of a CPU  which is interfaced to RAM and FLASH MEMORY. You just feed your program in flash memory of microcontroller. now  when you turn microcontroller ON , CPU accesses the instruction from RAM which access your code from FLASH. Its sets the configuration of pins and starts performing according to your program. 

HOW TO DO CODING/PROGRAMMING FOR MICROCONTROLLER?

YOU CAN WRITE PROGRAMS IN JAVA C++ AND C. THEN WE COMPILE THE CODE TO GENERATE ITS MACHINE LANGUAGE ie 0 and 1, NOW BURN IT IN MICROCONTROLLER USING A PROGRAMMER AND A SOFTWARE.

BETTER OPTION WOULD BE MAKING PROGRAM IN C AND THEN COMPILE IT IN MACHINE FILE(.hex) . AFTER THIS WE FEED PROGRAM IN FLASH MEMORY OF MICROCONTROLLER USING SUITABLE PROGRAMMER.

THIS PICTURE ABOVE IS A PROGRAMMER USE TO BURN OUR PROGRAM IN MICROCONTROLLER.

we will discuss about programs and softwares and hardwares to be used in upcoming post.
