Safety SBC with CAN Ringing Suppression: IM1169x

The Immorta IM1169x is a domestically-developed automotive-grade functional-safety SBC integrating multiple LDOs, a CAN SIC transceiver, and a watchdog. It fully complies with the ISO 11898-2:2016 / CiA 601-4 high-speed CAN transceiver standard, supporting communication rates up to 8 Mbit/s to ensure a high degree of compatibility and interoperability with other high-speed CAN bus devices.

Beyond its excellent communication performance, the IM1169x also features outstanding EMC characteristics, enabling it to cope with the stringent electromagnetic-compatibility environments of automotive applications and ensure system stability and reliability. Its selective wakeup function further reduces ECU power consumption, allowing efficient operation even in standby mode.
