Comparison of Microcontroller & Microprocessor:
Microprocessor :
1.CPU is stand-alone.
2.RAM, ROM, I/O, timer are external.
3.Size of ROM, RAM and I/O ports can be optimized.
4.For applications in which the accuracy and time are critical.
5.General-purpose system.
Microcontroller :
1.CPU, RAM, ROM, I/O and timer are all on a single chip.
2.Fixed size of on-chip ROM, RAM, I/O ports.
3.For applications in which cost, power and space are critical.
4.Task specific systems.
