LIN-J1 Connector
The TWR-S12G128 supports two, 2 x 2 Molex connectors to interface to the LIN bus. Figure 9
below details the pin-out of the LIN bus connector.

CAN Port
One, TJA1040T, High-Speed CAN physical-layer transceiver (PHY) is applied to support CAN
bus communications. A 4-pos, 4.22mm MOLEX connector interfaces to external CAN cabling.
Differential input CAN signals, are terminated with 120 ohms. Option headers, JP13 and JP15
allow the user to optionally disconnect signal termination. Avalanche diodes protect the CAN
PHY from voltage surges on the input differential signal lines. Figure 10 below shows the CAN
connector pin-out.
