CIN - CAN interface & Ethernet bridge


Board variant of the Sontheim CAN adapter as a com­mu­ni­ca­tion so­lu­tion for in­dus­trial sig­nal proces­sing app­li­ca­tions.

Key Features

  • Freescale micro­controller
  • Wide range of interfaces
  • Can be used as a board solution or as a communication centre in the Diag-Box
  • Internal flash and RAM memory
  • Also suitable for harsh environments due to increased temperature range
  • Extensive software support


In addition to a total of four CAN interfaces according to ISO 11898, the CIN has two single-wire CAN channels and eight digital inputs and outputs each. In addition, Ethernet and I²C are integrated for the control of peripheral components. Due to the extremely compact design, the CIN can be mounted as a piggyback variant on a customer-specific circuit board. Ultimately it is also possible to use the device as a gateway/bridge for CAN to Ethernet.

Level measurement
This feature makes it possible to read in the CAN levels analogously and thus, for example, to carry out fault diagnosis on a vehicle or machine. It is especially important when data is lost from the network, which can be caused by short circuits, for example.

Error frame detection
With this feature the CIN is able to take over debugging and diagnosis in a CAN network. The interface has its own logic that detects error frames and counts them in an internal memory. This allows sporadic errors, such as the corruption of messages by a station in the network, to be detected.
