A microcontroller is a small computer on a single metal-oxide-semiconductor integrated circuit chip.
✏️DIFFERENCE BETWEEN MICROCONTROLLER AND MICROPROCESSOR
✏️FACTORS THAT HAS TO BE REMEMBERED WHILE CHOOSING A MICROCONTROLLER
1. 8 bit, 16 bit, 32 bit microcontroller (whether we require any 1 one of these)
2. Speed
3. Packaging (either dual in line packaging or quad flat packaging)
4. Power consumption
5. The amount of ram and rom on the chip
6. The number of input output pins and timer on the chip.
7. Cost per unit.
8. How easily we can upgrade it to higher performance or lower power consumption.
9.The second microcontroller products criterion is how around it.
10.The third criterion microcontroller needed quantity is its both easy now in it in ready and choosing is to a develop choosing availability in the future a in .
✏️COMPONENTS OF A COMPUTER SYSTEM
*Address Bus:An internal channel from the CPU to memory across which the addresses of data (not the data) are transmitted. The number of lines (wires) in the address bus determines the amount of memory that can be directly addressed as each line carries one bit of the address.
*Data Bus: may refer to: Bus (computing), a communication system that transfers data between different components in a computer or between different computers. Memory bus, a bus between the computer and the memory.
* Control Bus:control bus is part of the system bus, used by CPUs for communicating with other devices within the computer.
✏️APPLICATIONS OF MICROCONTROLLER
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems.
