5. Power Consumption
5.1 System Power
The new Intel Pentium M processor family requires substantially more power than earlier Pen-
tium lll processors, although less than the Pentium 4. This results in special requirements for
the power supply and the backplane. The considerations presented in the ensuing chapters
must be taken into account by system integrators when specifying the CP383 system environ-
ment.
5.1.1 CP383 Baseboard
The CP383 baseboard itself has been designed for optimal power input and distribution. Still it
is necessary to observe certain criteria essential for application stability and reliability.
In the table below, absolute maximum input voltage ratings are specified to ensure that the
CP383 is not damaged during operation. Power supplies to be used with the CP383 should be
carefully tested to ensure compliance with these ratings.
The following table specifies the ranges for the different input power voltages within which the
board is functional. The CP383 is not guaranteed to function if the board is not operated within
the prescribed limits.
Table 5-1: Maximum Input Power Voltage Limits
SUPPLY VOLTAGE MAXIMUM PERMITTED VOLTAGE
+3.3 V +3.6 V
+5 V +5.5 V
+12 V +14.0 V
-12 V -14.0 V
Table 5-2: DC Input Voltage Ranges
INPUT SUPPLY VOLTAGE ABSOLUTE RANGE
+3.3 V 3.2 V min. to 3.47 V max.
+5 V 4.85 V min. to 5.25 V max.
+12 V 11.4 V min. to 12.6 V max.
-12 V -11.4 V min. to -12.6 V max.
