What is ISO 11898-6:2018?

ISO 11898-6:2018 is an international standard that specifies the high-speed medium access unit (HSMAC) and physical layer (PHY) of the controller area network (CAN) protocol. CAN is a widely used communication protocol in automotive and industrial applications.

High-Speed Medium Access Unit (HSMAC)

The HSMAC, as defined in ISO 11898-6:2018, is responsible for controlling the access to the CAN bus and managing collisions. It provides mechanisms for arbitration, message prioritization, and error handling. The HSMAC ensures efficient and reliable communication among multiple nodes connected to the CAN bus.

Physical Layer (PHY)

The PHY layer, also specified in ISO 11898-6:2018, defines the electrical characteristics and transmission medium for the CAN bus. It details the voltage levels, signaling scheme, and cable requirements. Compliance with these specifications ensures reliable data transmission over long distances and in noisy environments.

Benefits and Application

ISO 11898-6:2018 provides a standardized framework for implementing the CAN protocol in high-speed applications. Its benefits include improved data integrity, increased network efficiency, and interoperability among different manufacturers' devices. The standard is widely used in automotive systems, such as vehicle control units, engine management systems, and in-vehicle networks. It is also utilized in industrial automation, robotics, and other areas where real-time communication and robustness are essential.

In conclusion, ISO 11898-6:2018 plays a vital role in defining the HSMAC and PHY of the CAN protocol. It ensures reliable communication, efficient data transmission, and compatibility among various systems. Compliance with this standard is crucial for the successful implementation of high-speed CAN networks in automotive and industrial applications.
