Secure SBC Supporting CAN Ringing Suppression

Supports Selective Wake-up Function to Build Ultra-Low Power Electrical Systems

The Immorta IM1169 is a domestic automotive-grade SBC chip that integrates a CAN transceiver with Partial Networking (PN) management capabilities and Signal Improvement Capability (SIC). The CAN transceiver complies with the "ISO 11898-2:2024" physical layer compliance standard. Its CAN FD SIC feature supports data transmission rates up to 8 Mbps and provides seamless interoperability and excellent compatibility with various CAN bus devices, enabling efficient and stable data transmission in complex in-vehicle networks. 

IM1169 is equipped with comprehensive fault monitoring and diagnostic functions, along with an integrated independent watchdog circuit, supporting ASIL-B functional safety product development. It is widely applicable to various automotive electronic scenarios. In addition, IM1169 provides excellent EMC performance, with its CAN pins reaching HBM ±8kV and achieving Class A in BCI Level IV (200mA) testing, satisfying the stringent electromagnetic compatibility requirements of modern vehicles.
