Microprocessor vs. Microcontroller: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Microprocessor is a central processing unit on a single chip, used for complex computing tasks. Microcontroller is an integrated circuit with a processor, memory, and peripherals, for specific control applications.
Key Differences
A microprocessor is a computer processor on a microchip, focusing on computational tasks. It's the brain of a system, executing a series of programmed instructions. Microcontrollers, in contrast, are all-in-one chips designed for specific control tasks. They combine a processor with memory and input/output peripherals on a single chip.
