CiA 102 version 3.1.0 CAN physical layer for industrial applications
Scope

This document specifies and recommends the bit-timing settings for CAN interfaces, in order to achieve generic compatibility between CAN devices, in particular between CANopen field devices.

CiA 103 version 1.1.0 Intrinsically-safe CAN device interface
Scope

This document specifies an intrinsically-safe CAN device interface. It does not list the requirements by which an item of equipment can be certified as intrinsically safe nor does it require equipment to be intrinsically safe. NOTE 1 The document seeks to exclude conditions or situations that would prevent IS certification. Many parameters are selected by the developers to provide a baseline for calculation. NOTE 2 The wire-medium specification provides the option of intrinsically safe power via t he network conductors.

CiA 106 version 1.1.0 Connector pin-assignment recommendations
Scope

This document recommends the connector pin-assignment for CAN interfaces. This includes the CAN_H and CAN_L pins, the ground pin, and the power supply pins.

CiA 110 version 1.1.0 CAN common mode choke
Scope

This document specifies the requirements and the test methods of the mechanical and electrical parameters of common mode chokes to be used in Classical CAN networks and CAN FD networks. The electromagnetic compatibility evaluation complies with the IEC 62228-3:2019 standard. NOTE The common mode chokes with a maximum ambient temperature of +150 °C are not in the scope of this document, and will be considered in the next version if possible.

CiA 601-1 version 2.0.0 CAN FD node and system design - Part 1: Physical interface implementation
Scope

This set of documents specifies and recommends the usage of CAN FD hardware implementations. It consists of the following parts: Part 1: Physical interface implementation, Part 2: Controller interface specification, Part 3: System design recommendation, Part 4: Ringing suppression. This part provides specifications and guidelines on the physical layer interface design for automotive electronic control units and non-automotive devices supporting the CAN FD data link layer as defined in ISO 11898-1 and the CAN high-speed physical layer as defined in the harmonized ISO 11898-2 standard, which includes the specification of high-speed transceivers with low-power mode (formerly known as ISO 11898-5) and/or with selective wake-up functionality (formerly known as ISO 11898-6).

CiA 601-1 version 2.0.1 CAN FD node and system design, Part 1: Physical interface implementation
Scope

This part provides specifications and guidelines on the physical layer interface design for automotive electronic control units and non-automotive devices supporting the CAN FD data link layer standardized in ISO 11898-1:2024 and the CAN FD physical layer standardized in ISO 11898-2:2024.

CiA 601-2 version 1.0.0 CAN FD node and system design - Part 2: Protocol controller interface
Scope

This set of documents specifies and recommends the usage of CAN FD hardware implementations. It consists of the following parts: Part 1: Physical interface implementation, Part 2: Controller interface specification, Part 3: System design recommendation, Part 4: Ringing suppression. This part describes the specified interface between the protocol controller implementing the CAN FD data link layer protocol and the host controller including necessary configuration registers. Such a harmonized interface reduces the effort for adapting the low-level driver software to different implementations.

CiA 601-4 Calculator: arbitration bit rate and propagation delay for CAN FD networks using CAN SIC transceivers Attachment to the CiA 601-4 v. 2.1.0
Scope

This spreadsheet is an attachment to the CiA 610-4 v. 2.1.0. For different combinations of the CAN clock frequency and the oscillator tolerance values, this spreadsheet helps to calculate the values of the longest propagation delay between two nodes. The worst-case scenario is explained in detail in the spreadsheet.

CiA 601-4 version 2.1.0 CAN FD node and system design - Part 4: Signal improvement
Scope

This document specifies additional requirements for CAN transceivers compliant with ISO 11898-2:2016 for the purpose to reduce differential and common-mode ringing on the CAN_H and CAN_L wires, namely the CAN SIC transceiver. Furthermore, this document specifies EMC tests for the CAN SIC transceiver.
