Controller Area Network (CAN) Bus Technology

Originally created for automotive applications, CAN is a high-speed and reliable protocol for applications requiring robust communication at bit rates reaching 8 Mbps. The first production cars armed with CAN multiplex wiring systems rolled onto the streets nearly three decades ago, long before the commercial Internet or smartphones or digital media. Their introduction redefined the possibilities for in-vehicle communications and connectivity and triggered a perpetually evolving technology sector that has had far-reaching implications beyond the automobile. CAN offers key advantages to these and many other markets:

  • Automotive
  • Aviation
  • Agricultural
  • Building automation
  • Commercial transportation
  • Construction
  • Factory control
  • Marine
  • Medical
  • Military
  • Smart buildings

Products and Solutions for Your CAN Application

For systems that are sharing network capacity while starting, stopping and prioritizing access at the blink of an eye, data transmission speed and reliability are mission critical. Our comprehensive portfolio of CAN and CAN FD solutions includes microcontrollers, microprocessors and digital signal controllers with integrated CAN modules and a variety of external CAN controllers and transceivers for designing high-performance embedded applications. These products draw upon our rich heritage in the automotive industry and our commitment to providing you with easy-to-use development systems, an array of design resources and exceptional technical support as you design next-generation solutions.

Functional Safety for CAN Networks

Because CAN bus networks are intended to support data exchange amongst safety-critical functions, it is important to implement robust safety measures to reduce the risk of transmitting incorrect data. The safety features available in our CAN transceivers and controllers not only comply with the vigorous standards required for a functionally safe communication network, our proven experience and design support can help minimize your cost and development time.

CAN Connectivity for Automotive Applications

While cruise control and power windows were key upgrades for an automotive buyer a generation ago, today they are baseline features powered by one of many dozens of electronics control units (ECUs) located throughout the vehicle. The automotive market now demands innovative sensor-driven capabilities, especially to enhance driver safety and optimize engine performance. CAN-driven ECUs are commonly powering:

  • Engine control systems
  • Automatic transmissions
  • Active safety systems
  • Seat control units
  • Door modules
  • Trailer interfaces
  • Parking-assist controls
  • Collision-avoidance systems
