No. 5 - April 17, 2026
A word from the CiA Managing Director
The automotive industry is migrating to 48-V power supplies. This impacts the testing of CAN and LIN transceivers. They need to withstand 54-V shorts and also loss-of-ground or hot-swapping of CAN-/LIN-connected transceivers needs to be tested. CiA has had a related workshop in January. In the meantime, CiA has established the Special Interest Group (SIG) “48-V testing” chaired by Marko Moch (Cariad), reporting to the Interest Group (IG) “CAN lower layers”.
Additionally, CiA members discuss in the SIG “3,3-V transceivers” chaired by Lokesh Gupta (Texas Instruments) impacts on the ISO 11898-2 standard to include 3,3-V powered transceiver. There are ideas on the table, to mix legacy 5-V and 3,3-V transceivers in the same CAN network. Other parties like to specify 3,3-V SIC and SIC XL transceivers. The SIG also reports to the IG “CAN lower layers” chaired by Magnus Hell (Infineon).
A next meeting of the SIG “3,3-V transceivers” is in preparation.
Of course, both SIGs need to evaluate the requirements of automakers. Therefore, the SIG 48-V testing has scheduled a face-to-face meeting in Ingolstadt (Germany) at Audi/Cariad on May 6 and 7, 2026. Especially, OEMs (original equipment manufacturers) are invited to discuss with CAN transceiver suppliers the future of transceiver technologies in respect to 48-V environments. Tier-1 suppliers (device manufacturers) are also welcome to join this discussion.
For your information: Currently, ISO 11898-2 specifies CAN HS (high-speed) and CAN FD transceivers as well as CAN SIC (signal improvement) and CAN SIC XL transceivers. This includes transceivers supporting lower-power mode and selective wake-up capability. This standard is in FDIS (Final Draft International Standard) ballot. The so-called low-speed CAN transceiver is standardized in ISO 11898-3. There is also standardized a fault-tolerant transceiver for truck/trailer communication (ISO 11992-1).
CiA General Assembly 2026
End of March, the regular CiA General Assembly (GA) has re-elected Magnus Hell (Infineon) as Technical Director, Christian Schlegel (chs consulting) as Business Director, and Holger Zeltwanger as Managing Director. Additionally, the annual GA has voted for esd, emotas, MicroControl, Texas Instruments, and Vector as Business Committee members. The elected Technical Committee members are Bosch, esd, emotas, MicroControl, and Texas Instruments. The GA has also excluded CiA members, which did not pay their membership fees for 2025.
Online CiA technology day
On May 5, CiA has scheduled a four-hour online technology day. Several speakers present current and future trends in CAN technology. This includes presentations about the three CAN data link layers (CAN CC, CAN FD, and CAN XL), the CAN physical layer scalability, the CAN XL ecosystem, embedded AI (artificial intelligence) and CAN networking as well as CAN-related international standardization. Presentation language is English. Registration by email is obligatory.
CiA workshop: Greenhouse automation and vertical farming
On May 19 (10:00 to 12:00, UTC+2), CiA has scheduled a free-of-charge workshop in English language. Interested CiA members and invited guests will be informed about planned and ongoing standardization activities in the field of greenhouse automation and vertical farming. While the following discussions, requirements for CAN-based communication in such applications should be collected. Registration for the workshop is obligatory.
CiA calls for iCC papers
Next year, CiA celebrates its 35th anniversary in Tutzing at Starnberg Lake in Germany. From noon at March 3 to noon March 5, 2027, CiA organizes the 19th international CAN Conference (iCC). The call for papers has started, it ends at September 15, 2026. There is also the opportunity to sponsor this unique conference, which is accompanied by a tabletop exhibition. The long-term CiA member companies emotas and esd electronics have already agreed to sponsor the 19th iCC.
Details on the call for iCC papers, sponsoring, and exhibiting are available on the CiA website.
Hongke plans two online events
CiA member Hongke (China) is going to organize online events about “commercial vehicles, mobile machines, and mobile robots” (end of June) as well as about “energy management and energy storage” (end of May). Presentation languages are Mandarin and English. The Chinese company calls for papers. Presentations should be technology- or application-oriented, not just product placements. Interested parties can contact CiA office for details.
CAN Newsletter magazine
The CAN Newsletter magazine provides regular columns: “Facts & figures” contains news selected by the editors, “Latest news” reports about just before the editorial deadline received press releases, and “Standards & specifications” features information from standardization bodies as well as industrial consortia.
