3 TriBoard Information
3.1 Power Supply
The Board has to be connected to a +5,5V to +50V (+40V) DC power supply. The
TriBoard generates inte3.3V, +VDD and +5V. The power consumption is not
specified yet but a supply with 6V and 500mA should be sufficient. The pinout for the
supply connector is shown in
Figure 7-3 . There can be used any standard power pack
with a connector where the positive line is surrounded by the ground line.
Maximum power supply is reduced to +40V if the SAK-CIC61508 option is assembled
(always with TC1387).
+VDD is +1,3V for TC1782, for all other d1,5V. NOTE: on first TC1782 device
+VDD is +1,2V.
Applying a stable supply voltage causes the power on reset after a short period. The four
LED's (+5V, +3.3V, +VDD) indicate the status of the on board generated voltage (if the
LEDs are assembled).
A manual reset is executed by pressing the reset button.
3.2 LEDs
There are 14 or 19 LEDs on board:
– D501 up to D508 (blue) -> toogle LEDs connected to P5.0 ... P5.7
– D604 RST (red) -> RESET LED indicate the reset state of the board
– D505 +VDD (green) -> +VDD power supply indication (+1.3V/+1.5V)
– D606 +3V3 (green) -> +3,3V power supply indication
– D607 +5V (green) -> +5V power supply indication
– D402 ACT (green) -> on board MiniWiggler is ACTIV
– D401 RUN (red) -> Debug RUN mode (switched by DAS Server)
– D204 RST_CIC (red) -> RESET LED indicate that the CIC is in reset
– D205 +VDDP_CIC (green) -> +VDDP for CIC power supply indication (+3,3V)
– D201 SYSDISA (red)
-> System Disable A (switched by CIC)
– D202 SYSDISB (red) -> System Disable B (switched by CIC)
– D203 SYSDISC (red) -> System Disable C (switched by CIC)
3.3 Clock
There are three possibilities to apply the CPU clock.
•
Large oscillator circuit (DIP14)
• Small oscillator circuit (DIP8)
• Crystal oscillator (default with 20MHz)
• External clock generator
