Microprocessor vs Microcontroller – 4 Differences

Aspect Microprocessor Microcontroller
1. Integration CPU only, needs external memory/I/O CPU+RAM+ROM+I/O+timers on single chip
2. Cost/Size Higher system cost, larger PCB Low cost, compact
3. Applications General-purpose computing (PC) Dedicated control (appliances, automotive)
4. Power & Performance High speed, high power Low-mid speed, low power
Extra: MP uses Von Neumann external buses, MC Harvard on-chip. MP needs more support ICs, MC single-chip.
