CAN SIC XL

NXP's Controller Area Network (CAN) Signal Improvement Capability (SIC) XL series is designed to deliver high-speed, high-payload communication for autonomous vehicles and industrial applications. The TJA148x family supports data rates of up to 20 Mbit/s and 2048-byte payloads, enabling ultra-low microsecond latency—even across expansive networks with extended stubs and diverse topologies.

In addition to Signal Improvement Capability (SIC) mode, the TJA148x CAN SIC XL series introduces FAST mode, which converts a Transmit Data (TXD) Pulse-Width Modulation (PWM) signal into symmetrical differential bus signals. This enables consistently high data rates of up to 20 Mbit/s, supporting larger network architectures without the cost and complexity of subnetworks. Support for large payloads from sources such as corner radars and battery management systems (BMS) reduces or eliminates the need for data segmentation, while Ethernet tunneling support helps streamline system integration.

For seamless upgrades, the CAN SIC XL family maintains pin compatibility with conventional high-speed CAN transceivers, supporting simple design transitions and backward compatibility. The series fully meets ISO 11898-2:2024 Annex A (CAN XL) and embodies the ISO 11898-2:2024, including specification, helping to ensure robust compliance and reliability.
