Texas Instruments TCAN4550/TCAN4550-Q1 CAN FD Controller has an integrated CAN FD transceiver supporting data rates up to 5Mbps. The CAN FD controller meets the specifications of the ISO11898-1:2015 high-speed Controller Area Network (CAN) data link layer. It also meets the physical layer requirements of the ISO11898–2:2016 high-speed CAN specification. The TCAN4550/TCAN4550-Q1 provides an interface between the CAN bus and the system processor through a serial peripheral interface (SPI), supporting both classical CAN and CAN FD. The TCAN4550/TCAN4550-Q1 provides CAN FD transceiver functionality: differential transmit capability to the bus and differential receive capability from the bus. The device supports wake-up via local wake-up (LWU) and bus wake using the CAN bus implementing the ISO11898-2:2016 Wake-Up Pattern (WUP). The Texas Instruments TCAN4550-Q1 devices are AEC-Q100 qualified for automotive applications.
