Before an automotive ECU (Electronic Control Unit) can go into production, it must pass rigorous physical layer compliance tests outlined by the standard.
Because ISO standards are protected by copyright, they are not typically available for free. You can obtain official, high-quality PDF versions from the following authorized sources: ISO 11898-2:2016 - Controller area network (CAN)
: The American National Standards Institute provides the PDF for digital download. Design engineers need the standard to verify that
It describes the transceiver characteristics required for data rates up to 1 Mbit/s (and higher with CAN FD) within vehicles and industrial environments. Key Aspects Covered in the ISO 11898-2 Standard
ISO 11898-2 specifies the of the Controller Area Network (CAN). It defines how electrical signals are transmitted across the physical wires (usually a twisted pair) to ensure reliable communication between Electronic Control Units (ECUs) in vehicles and industrial machinery. Evolution of the Standard
The standard serves as the absolute backbone for modern automotive communication. If you are designing an Electronic Control Unit (ECU) or working with in-vehicle networks, understanding this specific document is non-negotiable. You can obtain official, high-quality PDF versions from
The ISO 11898 standard has undergone several revisions to keep up with technological advancements:
Introduced specifications for low-power mode (wake-up capabilities).
