TriBoard Information
3.10 LIN
On the board is one LIN transceiver connected to the ASCLIN1 on TC3X4 LQFP (P15.0 and P15.1). The transceiver
are connected to one IDC10 plug. For the pinout of IDC10 plug see
Figure 6-7 . You can use a IDC female connector
with crimpconnector, flat cable and SUB-D 9 plug with crimpconnector to have a 1:1 adapter to SUB-D 9.
To disconnect the LIN remove resistor R364 and R365.
The LIN can be used in master and in slave mode. For the master mode there is per default a pull-up of 1K (R360)
and a capacitor of 1nF (C304) on the BUS assembled. For using the LIN in slave mode the pull-up resistor R360
must be removed and maybe the capacitor changed to a smaller value (e.g. 220pF).
The mentioned resistor and capacitor are red marked in
Figure 3-3
Figure 3-3 Components for LIN Master Mode
3.11 Ethernet
The TriBoard provide a RJ45 connector (X306) for twisted pair ethernet connections.The TriBoard use a Realtek
Single-Chip/Port 10/100M Ethernet PHYCEIVER with Auto MDX RTL8201FI-VC-CG as physical interface device. For
more information about the ethernet modul see TC3X4 User’s Manual, about the PHY see the RTL8201FI
datasheet. For the pinout of RJ45 see
Figure 6-9 .
The PHY is connected to the TriCore device via resistors and resistor arrays (R368 up to R374) which must be
removed to use the ports outside.
For the connection between TriCore and PHY is used RMII.
For MD connection there is used P00.0 and P02.8. To use this communication way please make sure that R376 is
not assembled (default). For R376 position please see also
Figure 4-4 .
Note: Please note that the RGMII interface can’t be used of limited pin availability. Therefore Gigabit is not
usable with this board only 10M and 100M.
