TriBoard Information
Per default the miniWiggler is connected to the DAP. It is possible to change the connection to DAPE (DAP of
emulation device if available). If resistors R214, R215 and R216 assembled (default) then the standard DAP is
connected to miniWiggler otherwise if R217, R218 and R219 are assembled the the DAPE of emulation device is
connected to miniWiggler. Please note that there should be connected only standard DAP or DAPE. If all this
resistors are not assembled then the miniWiggler can’t be used. In this case only the DAP connectors X402 and
X403 can be used. See
.
3.6
FlexRay™ (E-RAY)
The board has 2 IDC10 plugs for FlexRay™ Communication (channel A and B) with up to 10 Mbit/s. For the pinout
of the plugs see
. 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.
The transceiver are connected to the TriCore device via zero ohm resistors (R325 up to R329 and R340 up to R344)
which must be removed to use the ports outside.
ERAY-A can be connected to P14.8, P14.9 and P14.10 (default, usable with ERAY0 and ERAY1) and to P02.0, P02.1
and P02.4 (only usable with ERAY0). Transceiver for channel A can be enabled/disabled via P32.3 (default) or via
P10.2. The error state of transceiver channel A can be read out via P32.2 (default) or via P10.1.
ERAY-B is connected to P14.5, P14.6 and P14.7 (default, usable with ERAY0 and ERAY1). Transceiver for channel A
can be enabled/disabled via P20.10 (default). The error state of transceiver channel A can be read out via P20.9
(default).
For more information look in the user manual for TC3X7.
3.7
Serial Eeprom
The I
2
C via P15.4 and P15.5 of the TC3X7 is connected to a serial EEPROM with a size of 2KBit (2 x 128 x 8). The
slave address of this EEPROM is 0x50. The upper half of the array (80h-FFh) is permanently write-protected. Write
operations to this address range are inhibited. Read operations are not affected. This upper half contains a pre-
programmed EUI-48™ node address which can be used as MAC ID for Ethernet. The other 128 bytes are writable
by customer.
To disconnect (disable) the EEPROM remove resistor R348 and R349.
3.8
MultiCAN
On the board are two CAN transceiver connected to the CAN0 and CAN1 of TC3X7. The transceivers are connected
to two IDC10 plug. For the pinout of IDC10 plug see
. 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.
The transceiver are connected to the TriCore device via zero ohm resistors (R301 up to R304 and R311 up to R314)
which must be removed to use the ports outside.
CAN0 can be used via P20.7 and P20.8 (node 0, default) or P14.0 and P14.1 (node 1). CAN1 can be used via P23.0
and P23.1 (node 0, default) or P00.0 and P00.1 (node 0).
3.9
LIN
On the board is one LIN transceiver connected to the ASCLIN1 on TC3X7 (P15.0 and P15.1). The transceiver are
connected to one IDC10 plug. For the pinout of IDC10 plug see
. 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.
