8-bits Microcontrollers - MCU

8-Bit Microcontrollers are in stock with same-day shipping at Mouser from industry leading manufacturers. Mouser is an authorized distributor for many 8-bit microcontroller manufacturers including Microchip, NXP, Silicon Labs & more.

8-bit microcontrollers are compact embedded processing devices that integrate a CPU, memory, and input/output peripherals onto a single chip for control-oriented applications. Designed for simplicity, efficiency, and cost-effectiveness, they provide reliable performance for tasks that require straightforward processing and real-time control. These microcontrollers remain widely used across a broad range of electronic systems where low power consumption, proven reliability, and ease of implementation are important design considerations.

Types: The most common 8-bit microcontroller types include AVR®, PIC®, 8051-based, and other general-purpose 8-bit architectures, with variants optimized for low-power operation, connectivity, industrial control, and cost-sensitive embedded applications.

Applications: 8-bit microcontrollers are widely used in industrial automation equipment, home appliances, consumer electronics, sensors, motor control systems, lighting controls, battery-powered devices, and embedded monitoring applications requiring efficient control and signal management.

Selection requirements: To choose 8-bit microcontrollers, evaluate processing speed, memory capacity, power consumption, available peripherals, communication interfaces, operating voltage range, package type, development ecosystem, and suitability for the intended application and environmental conditions.
