The new standard CAN FD

With the release of various hardware and software products, PEAK-System is a pioneer in the introduction of the new CAN FD standard.

With CAN FD (Flexible Data rate) the robust and long- lasting CAN specification has been extended with properties which are primarily designed for larger amounts of data. Higher bit rates up to 12 Mbit/s for the data of the CAN frames and the use of up to 64 data bytes in a single CAN frame are the main criteria.

CAN FD is downward-compatible to the CAN 2.0 A/B standard, thus CAN FD nodes can be used in existing CAN networks. However, in this case the CAN FD extensions are not applicable.

Since the first implementations of CAN FD, the protocol has been improved and is now included in the standard ISO 11898-1. The revised CAN FD standard is not compatible with the original protocol. PEAK-System takes this into account by supporting both protocol versions with their CAN FD interfaces. If required, the user can switch to the CAN FD protocol used in the environment by software („Non-ISO“ and „ISO“).

CAN-FD-compatible CAN products

Some of our existing CAN products can be operated with the standard CAN FD, due to their operating principle.
