ISO 11898-2 is the international standard for the High-Speed Medium Access Unit of the Controller Area Network (CAN) . It defines the Physical Layer requirements, ensuring that different devices (nodes) can communicate reliably over the same two-wire bus . ISO 11898-2 Official PDF & Documentation
The standard is a copyrighted document and is not typically available for free download from official sources. You can obtain it through the following official channels:
ISO Store: The official source for the most recent version, ISO 11898-2:2024 .
National Standards Bodies: Organizations like ANSI (American National Standards Institute) or BSI (British Standards Institution) often provide digital copies for purchase and download .
Technical Libraries: Many university and corporate libraries offer digital access to standards through platforms like IEEE Xplore. Key Technical Guide Summary
If you are looking for a guide to implementing the standard rather than the full legal text, these technical points cover the core requirements:
Baud Rates: Supports data rates up to 1 Mbit/s for Classical CAN and up to 8 Mbit/s for CAN FD .
Bus Topology & Termination: Uses a linear bus topology. To prevent signal reflections, a 120 Ω termination resistor must be placed at both ends of the bus . Voltage Levels:
Recessive State: Both lines (CAN_H and CAN_L) are at approximately 2.5V .
Dominant State: CAN_H rises to ~3.5V and CAN_L drops to ~1.5V, creating a differential voltage .
Wiring Requirements: Typically requires a twisted-pair cable to minimize electromagnetic interference (EMI) . Recommended Practical Resources
