Microcontroller and microprocessor have address bus, data bus and control bus. Similarity and difference between microcontroller and microprocessor.ĭifference between Microcontroller and microprocessor-Hardware perspectiveĪs Mentioned in the figures, Microcontroller and microprocessor both have got CPU, ALU and registers (PC, IR, etc). The layout of a microprocessor ( Figure 1) includes and address bus (8, 16, or 32 bits wide) that enables address to be sent to memory, a data bus (8, 16, or 32 bits wide) that enables data to be sent or received to/from memory, a Read (RD) and Write (WR) line that allows memory to receive direction, a clock line to set the processors pulse sequence, a reset line that allows the processor to be reset to ‘zero.This page Microcontroller versus microprocessor describes

In comparison, microprocessors (MPUs) lie at the center of embedded systems and control operations in many functions of computing. In fact, there are so many applications for MCUs, that it would be difficult (and lengthy) to list every application in one article. MCUs are a part of almost every electronic device we use from desktops and laptops to smartphones, calculators, medical devices, and wearables. Microcontrollers (MCUs) are the center of computing.
