8.1 Overview

The TCAN1044AEV-Q1 meets or exceeds the specifications of the ISO 11898-2:2016 high-speed CAN (Controller Area Network) physical layer standard. The devices have been certified to the requirements of ISO 11898-2:2016 physical layer requirements according to the GIFT/ICT high speed CAN test specification. The transceivers provide a number of different protection features making it ideal for the stringent automotive system requirements while also supporting CAN FD data rates up to 8 Mbps.

The TCAN1044AEV-Q1 supports the following CAN and CAN FD standards:

  • Physical layer:
    • ISO 11898-2:2016 High-speed medium access unit
    • ISO 11898-5:2007 High-speed medium access unit with low-power mode
    • SAE J2284-1: High-Speed CAN (HSC) for Vehicle Applications at 125 kbps
    • SAE J2284-2: High-Speed CAN (HSC) for Vehicle Applications at 250 kbps
    • SAE J2284-3: High-Speed CAN (HSC) for Vehicle Applications at 500 kbps
    • SAE J2284-4: High-Speed CAN (HSC) for Vehicle Applications at 500 kbps with CAN FD Data at 2 Mbps
    • SAE J2284-5: High-Speed CAN (HSC) for Vehicle Applications at 500 kbps with CAN FD Data at 5 Mbps
  • EMC Requirements
