3.3.1 Overview

The networking block supports both CAN and LIN interface:

  • The CAN transceivers are embedded on the UC3C-EK (U9 and U11) and termination resistors can be used as bus configuration through 2-pin headers (J9 and J14). See Configurations and Test Points. The physical connections of CAN bus are accessible through DB9 connectors (J10 and J15).

  • The LIN transceivers are embedded on the UC3C-EK (U10 and U12). The master/slave configurations are accessible through 2-pin headers (J12 and J17). The board supports also the capability to be powered-up by LIN bus through 2 pin headers (J11 and J16). See Configurations and Test Points. The physical connections of LIN bus are accessible through 3-pins headers (J13 and J18).
