Memory, I/O ports, timers, interrupts are not available inside the chip	All are integrated inside the microcontroller chip
This must have many additional digital components to perform its operation	Can function as a micro-computer without any additional components.
Systems become bulkier and expensive.	Make the system simple, economic and compact
Not capable for handling Boolean functions	Handling Boolean functions
Higher accessing time required	Low accessing time
Very few pins are programmable	Most of the pins are programmable
Very few number of bit handling instructions	Many bit handling instructions
Widely used in modern PC and laptops	Widely used in small control system
Eg. Intel, 8086, INTEL Pentium series	Eg. INTEL 8051, 89960, PIC 18F877
