Abstract: The Controller Area Network (CAN) protocol, originally designed more than two decades ago, has been widely used in multiple domains, including industrial control, automotive and aerospace. To overcome two important limitations of the original CAN protocol, low data transmission rates and small data frame payload sizes, a new specification, the CAN with Flexible Data rate (CAN FD), was issued. This paper addresses timing and safety issues of the new specification, demonstrating that CAN FD, although showing an improvement of timeliness in the absence of errors, continues to exhibit (almost) the same shortcomings of the original protocol with respect to its use in the design of highly reliable real-time embedded systems.
