Farnell offers an extensive selection of microcontrollers (MCUs) tailored for a wide range of embedded system applications. Our portfolio includes top-performing architectures like ARM, AVR, and PIC microcontrollers, designed to meet varying performance and power requirements for both simple and complex operations.

Microcontrollers are integrated circuits that combine a processor, memory, and input/output (I/O) peripherals into a single chip. Acting as the "brain" of embedded systems, they control the functions of electronic devices, from basic sensors to advanced control systems.

Microcontroller Applications:

 

  • IoT Devices: Powering smart devices such as sensors, wearables, and home automation systems.
  • Automotive Systems: Managing critical functions like braking systems, fuel injection, and traction control.
  • Robotics: Enabling motion control, sensor integration, and automation tasks.
  • Industrial Control: Driving systems for process control, and industrial instrumentation.
  • Consumer Electronics: Used in devices like thermostats, smoke detectors, and audio systems.
  • Medical Devices: Supporting medical instrumentation and monitoring devices.

Our microcontrollers are designed to deliver exceptional performance while optimizing energy efficiency, making them ideal for battery-powered applications. With a range from 8-bit to 32-bit processors, they provide the necessary power for both simple and complex systems. Many of our MCUs also feature integrated support for peripherals like Bluetooth, Wi-Fi, and camera interfaces, ensuring smooth integration into a variety of devices.
