TriBoard TC176X/TC116X/TC1782/TC1387
Hardware Manual
TriBoard Information
User’s Manual 3-3 V 2.1, 2009-06
IMPORTANT: Make sure that there is no or a tristated connection on X401 (OCDS1) and
X402 (DAP) if the ACTIV LED is on.
3.5 FlexRay / IFlex (optional if not with TC1767, TC1782 or TC1387)
The FlexRay devices are only assembled if the board is with TC1767, TC1782, TC1387
or with the FlexRay option.
The board has 2 SUB-D connectors for FlexRay Communication with up to 10 Mbit/s.
For the pinout of the plugs see
Figure 7-5 .
The transceiver are connected to the FlexRay Communication Controller SAK-CIC310
(IFlex).
Normally the SAK-CIC310 is connected to MLI0 of the TriCore Controller but the IFlex
can also be connected to SSC1.For using the IFlex with SSC see
Table 4-4 . As
interrupts inputs of TC176X/TC116X are used P0.7, P0.11, P3.10 and P3.11 and in case
of SSC1 connection you can also use P0.6.
For more information look in the user manual for TC176X/TC116X or SAK-CIC310 and
the schematics
Figure 8-4 .
3.5.1 FlexRay as option
If the board comes without FlexRay (e.g. with TC1766) then you can add the FlexRay
option by assembling the following parts:
•
U301 with SAK-CIC310 (Infineon)
• U302 and U303 with AS8221 (AMS) or TJA1080 (NXP) (if with TJA1080 then
resistors R366-R371 and capacitor CB312 and CB316 must be assembled with 0R
and 100n, package 0603)
• Y301 with 20MHz crystal (5x3mm SMD, e.g. NDK NX5032GA)
• T301 and T302 with B82790-S513-N (Epcos)
3.6 Serial Eeprom
The SSC0 of the TC176X / TC116X / TC1782 / TC1387 is connected to a serial
EEPROM with a size of 128K (16.384 x 8). As chip select for this EEPROM is used the
line SLSO00 (P3.5). To disconnect (disable) the EEPROM remove resistor R353.
3.7 MultiCAN
On the board are two CAN transceiver connected to the MultiCAN on TC176X / TC116X
/ TC1782 / TC1387 node 0 and 1. The transceivers are connected to two IDC10 plug.
For the pinout of IDC10 plug see
Figure 7-6 . 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.
