Microcontrollers - MCU

Microcontrollers are in stock with same-day shipping at Mouser. Mouser is an authorized distributor for many leading microcontroller manufacturers including Infineon, Microchip, NXP, Renesas, Silicon Labs, STMicroelectronics, Texas Instruments and more.

Microcontrollers are highly integrated semiconductor devices that combine a processor core, memory, and peripheral functions onto a single chip to perform embedded control and processing tasks. Designed to monitor inputs, execute programmed instructions, and control outputs, they provide efficient operation for a wide range of electronic systems. These versatile devices serve as the intelligence behind countless products, enabling automation, connectivity, monitoring, and real-time decision-making functions.

Types: The most common microcontroller types include 8-bit, 16-bit, and 32-bit microcontrollers, ARM®-based microcontrollers, low-power microcontrollers, wireless microcontrollers, automotive-grade microcontrollers, and industrial microcontrollers, each optimized for specific performance, power, and application requirements.

Applications: Microcontrollers are widely used in industrial automation equipment, Internet of Things (IoT) devices, motor control systems, consumer electronics, medical devices, automotive electronics, smart appliances, sensors, and embedded control applications requiring reliable processing and system management.

Selection requirements: To choose microcontrollers, evaluate processing performance, memory capacity, operating voltage, power consumption, peripheral integration, communication interfaces, security features, package type, development ecosystem, and suitability for the intended electrical and environmental conditions.
