4.3 Networking
The networking block of the AT32UC3C-EK covers all components providing CAN
and LIN bus interfaces through DB9 connectors and 3-pins headers.
4.3.1 Overview
Figure 4-8. Atmel AT32UC3C-EK Networking Logical View
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 4.1.3.1 section. 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 4.1.3.1 section. The physical connections of LIN bus
are accessible through 3-pins headers (J13 and J18).
