XS_CAN
Benefits
Supports CAN CC, CAN FD and CAN XL
Supports CAN XL with up to 20Mbit/s and 2048-byte data payload
Supports CAN FD light commander with up to 8 Mbit/s
Physical Layer
CAN_XL 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
- CAN SIC XL up to 20 Mbit/s
CAN XL and CAN FD can be operated in mixed CAN FD / XL networks
CAN FD light can use all transceivers up to 8Mbit/s
Optional Add-on
CTDMA – Cut Trough DMA unit
- DMA (Direct Memory Access) optimized for XS_CAN
- Use system memory for storage of CAN messages
- Only Small local memory needed
Status
The specification of the CAN_XL 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 XL. 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.
