Power Considerations
5.1
System Power
The considerations presented in the ensuing chapters must be taken into account by system
integrators when specifying the CP305 system environment.
5.1.1
CP305 Baseboard
The CP305 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.
The table below indicates the absolute maximum input voltage ratings that must not be exceed-
ed. Power supplies to be used with the CP305 should be carefully tested to ensure compliance
with these ratings.
Table 5-1:
Maximum Input Power Voltage Limits
SUPPLY VOLTAGE
+3.3 V
+5 V
Warning!
The maximum permitted voltages indicated in the table above must not be
exceeded. Failure to comply with the above may result in damage to your
board.
The following table specifies the ranges for the different input power voltages within which the
board is functional. The CP305 is not guaranteed to function if the board is operated beyond
the prescribed limits.

DC Operational Input Voltage Ranges
INPUT SUPPLY VOLTAGE
+3.3 V
+5 V
ID 1035-7168, Rev. 1.0
MAXIMUM PERMITTED VOLTAGE
+3.6 V
+5.5 V
ABSOLUTE RANGE
3.2 V min. to 3.47 V max.
4.85 V min. to 5.25 V max.
Power Considerations
RECOMMENDED RANGE
3.3 V min. to 3.47 V max.
5.0 V min. to 5.25 V max.
