•
The above diagram is valid for a usage at heights up to 1000 m above sea
level. For higher heights the maximum temperature values have to be
reduced in an appropriate way.
•
The core temperature of the CPU can be read out via the onboard
temperature sensor. The value must be kept below 100 °C for all operating
conditions. This value is already included in the airspeed diagram above. If
this temperature limit is violated, the Core™ Duo CPUs will start to reduce
its internal frequency temporarily. This can be heard by a short click of the
speaker which occurs every 0.8 seconds. The Celeron processor will not
automatically switch down to lower frequencies but will stop its internal
clock in preprogrammed intervals.
•
When using an onboard hard disk drive (not with flash disk) the operating
temperature is limited to 50 °C
•
When using one or two PMC modules, please consider their power
consumption and thermal limits in calculating the max. operating
temperature
Card edge temperatures for VR11 style 8
Table 30: Card edge temperatures for style 8
Processor Card edge temperature style 8
Core 2 Duo LV 1.5 GHz 70 °C
Core 2 Duo 2.16 GHz 60 °C
Core Duo ULV 1.2 GHz 70 °C
Core Duo LV 1.67 GHz 70 °C
Core Duo 2.0 GHz 65 °C
These values do not include temperature variations due to PMC modules.
For even more detailed information especially on the style 8 versions, please
check the thermal report document TR-HW-012 of the VR11.
Electrical Characteristics
The supply voltages are +5 V and 3.3 V. +12 V and -12 V are required only if
needed on the PMC slot. All Output voltages of the VR11 boards have an over-
current protection. The maximum current for each voltage is shown below:
