IG04 Lower layers

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.

Scope

This document specifies the time-stamping, when transmitting and receiving CAN data frames in classical CAN and CAN FD formats. This time synchronization can be used in particular in AUTOSAR environments. Therefore, a link to the AUTOSAR time synchronization is described.

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: Signal improvement, Part 6: CAN FD cable. This part specifies the requirements and test methods of the mechanical and electrical parameters for cables to be used in CAN FD networks.

Scope

This set of documents recommends the usage of CAN FD hardware implementations. It consist of the following parts: Part 1: Physical interface implementation, Part 2: CAN controller interface specification, Part 3: System design recommendation, Part 4: Signal improvement. This part provides recommendations for CAN FD network design, especially, bit-timing setting rules and guidelines are given. This part also includes the spreadsheet that helps to perform the CAN clock tolerance calculation, the bit-timing evaluation and optimization, the bit asymmetries calculation, and the evaluation of the robustness.

Scope

This document provides recommendations for using CAN FD in “low-speed” applications. The term “low-speed” represents bitrates of under 1 Mbit/s in the arbitration phase. Typically, applications that demand large physical network dimensions (e.g., lifts, vessels, rolling stock, reduce are limited in their communication speed, for example to 125 kbit/s. In order to keep latency on the bus low even when using CAN FD data frames, which can support a significantly larger data field compared to CAN CC, such applications call for a bit rate switch to a higher value in the data phase; for example, 500 kbit/s. This document provides recommendations for bit timing configurations for "low-speed" bitrates with today’s CAN controllers, complementing the bit timing recommendations from CiA 1301 (??//Relationship between this document and CiA 1301 needs to be clarified)etc.)
