Microcontrollers (MCUs) are highly integrated embedded control devices that combine a processor core with on-chip resources to execute dedicated firmware. They are designed to provide self-contained control and decision-making functions within electronic systems.

Within the broader category of Embedded Processors & Controllers, MCUs typically integrate multiple functional blocks into a single device, such as:

• Processing logic for running embedded software
• Memory resources to store program code and data
• Peripheral interfaces for interacting with external components and signals
• Timing and control features to coordinate system operation

Microcontrollers are selected based on architectural compatibility, available on-chip functions, and overall system integration needs, serving as a central control element in embedded electronic designs.
