Difference between a microcontroller and a microprocessor?

Click For Summary
SUMMARY

The primary distinction between a microcontroller and a microprocessor lies in their architecture and functionality. A microprocessor serves solely as the core processing unit, handling logic operations and machine code interpretation, while a microcontroller integrates a microprocessor with additional on-board peripherals such as A/D converters, DACs, and interface units. Although the definitions can blur due to varying interpretations of what constitutes a peripheral, the fundamental difference remains clear. Programming for microcontrollers typically utilizes languages like C or assembly language.

The strict difference is that a microprocessor is just the "core" processing unit (logic operations, interpretation of machine code), with some basic inputs and outputs. A microcontroller contains a microprocessor, and additional on-board peripherals (A/D converters, DACs, servo controllers, fancy interface units, etc.)

In practice however, the line blurs a fair bit between self-declared microprocessors and self-declared microcontrollers (does, say, a floating point unit count as a peripheral?) But that's a semantics issue.

Usually C or assembly language.
