Texas Instruments TCAN4551-Q1 Automotive CAN FD Controller
Texas Instruments TCAN4551-Q1 Automotive CAN FD Controller has an integrated CAN FD transceiver that supports data rates up to 8Mbps. The TCAN4551-Q1 CAN FD controller meets the specifications of the ISO11898-1:2015 high-speed CAN data link layer and the physical layer requirements of the ISO11898–2:2016 high-speed CAN specification.
The TCAN4551-Q1 interfaces the CAN bus and the system processor through SPI, supporting classic CAN and CAN FD. This feature allows port expansion of CAN and CAN FD or CAN support with processors that do not support CAN FD. The TCAN4551-Q1 implements CAN FD transceiver functionality of 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 TCAN4551-Q1 includes many protection features that produce the device and CAN bus robustness. These features include failsafe features, internal dominant state timeout, and a wide bus operating range.
The Texas Instruments TCAN4551-Q1 devices are AEC-Q100 qualified for automotive applications.
