Microcontrollers
Definition
Microcontroller
A compact integrated circuit used to control specific operations in an embedded system. It contains a processor, memory, and input/output interfaces all in one chip.
Key Features of Microcontrollers
- Programmability: Microcontrollers can be programmed to perform specific tasks, making them versatile for different applications.
- Integration: They combine a processor, memory, and input/output (I/O) peripherals on a single chip.
- Efficiency: Designed for low power consumption, making them ideal for battery-powered devices.
- Cost-Effectiveness: Mass production and integration reduce costs, making them accessible for a wide range of applications.
- Microcontrollers include everything they need (like memory and input/output connections) on one chip, while microprocessors need extra parts.
- This makes microcontrollers better for small, embedded systems.
How Microcontrollers Work in Control Circuits
- Input: Sensors or user interfaces provide data to the microcontroller.
- Processing: The microcontroller executes programmed instructions to analyse the input.
