CAN-LIN Gateway ECU

The CAN-LIN Gateway ECU is an electronic control unit that features up to two CAN/CAN FD channels, a LIN channel, and several multi-purpose digital/analogue inputs and outputs.

The control unit is fully configurable and can be used as a stand-alone data converter between a CAN/CAN FD network and a LIN bus, or as a remote I/O module to interface sensors and actuators to CAN and LIN systems. The control unit supports both SAE J1939 and raw CAN protocols, and is suitable for mobile and stationary applications in harsh automotive and industrial environments.

The ECU Configurator (p/n: GW-ECU-CONFIG-TOOL) PC application allows to easily configure the ECU over CAN bus. The user can set ECU’s mode, communication channels’ parameters, inter-channel frame conversion (frame mappings), and I/O mappings. The configuration is stored in the device’s non-volatile memory.

The CAN-LIN Gateway is available in several variants that offer combinations of single-CAN / dual-CAN (CAN FD supported), with/without CAN termination, and automatic wake-up and sleep based on CAN bus activity / control over the ignition switch (KL15) input signal.
