The TCAN4550-Q1 is a CAN FD controller with anintegrated CAN FD transceiver supporting data rates up to 8 Mbps. The CAN FD controller meets thespecifications of the ISO11898-1:2015 high speed controller area network (CAN) data link layer andmeets the physical layer requirements of the ISO11898–2:2016 high speed CAN specification. TheTCAN4550-Q1 provides an interface between the CAN bus and the system processorthrough serial peripheral interface (SPI), supporting both classic CAN and CAN FD, allowing portexpansion or CAN support with processorsthat do not support CAN FD. The TCAN4550-Q1 provides CAN FD transceiverfunctionality: differential transmit capability to the bus and differential receive capability fromthe bus. The device supports wake up via local wake up (LWU) and buswake using the CAN bus implementing the ISO11898-2:2016 Wake Up Pattern (WUP).

The device includes many protection features providing device and CAN bus robustness.These features include failsafe mode, internal dominant state timeout, wide bus operating range and a time-out watchdog as examples.
