A
microcontroller is a programmable digital processor with necessary peripherals.
Both microcontroller and microprocessor carry out job according to
program/instruction, and both are complex sequential digital circuit.

MICROCONTROLLER
vs MICROPROCESSOR
- MICROPROCESSOR ,unlike microcontroller requires external memory for instruction/program storage.
- A microcontroller does not require additional interfacing ICs for operation and its function as a stand alone system.
- A microcontroller has required on chip memory with associated peripherals.
- A microcontroller clock speed is limited to few tens of megahz, while microprocessors have higher clock speed.
