Protocol controller IP for a CAN FD light responder node

The FDLR_CAN is a CAN IP module that can be implemented in an ASIC, FPGA, and mixed-signal device.It supports CAN FD light responder communication according to ISO 11898-1:2024.

For connection to the CAN physical layer, additional transceiver hardware is required. The FDLR_CAN is being developed as Safety Element out of Context (SEooC) according to ISO 26262-11:2018 Clause 4. Safety Manual and FMEDA are available on request.

Physical Layer

CAN FD light will be operable with all CAN transceiver types:

• Classical CAN up to 1Mbit/s
• CAN FD up to 2Mbit/s
• CAN SIC up to 5-8Mbit/s

Status

The specification of the CAN FD light protocol and physical layer is released by the ISO (International Organization for Standardization):

• The ISO 11898-1:2024 specifies the CAN protocols (CAN CC, CAN FD, CAN FD light and CAN XL)
• The ISO 11898-2:2024 specifies the CAN transceivers (CAN HS, CAN FD, CAN SIC, CAN SIC XL)

In addition, many other CAN related standards will be updated simultaneously to support CAN FD light. E.g. the CAN Conformance Test according to ISO 16845

Mandatory License of CAN Protocols

The CAN Protocols are patented products developed by Robert Bosch GmbH.

A CAN Protocol License is required for all implementations of CAN FD, CAN FD light, TTCAN and CAN XL modules.

• Support of CAN FD light
• Bit rate of up to 8Mbit/s, user configurable
• 1x Message Buffer (MB)
