Power supply pins on the module’s connectors limit the amount of input power. The following table provides an overview of the limitations for
pinout Type 2 (dual connector, 440 pins).

Power Consumption
The power consumption values listed in this document were measured under a controlled environment. The hardware used includes a conga-CLX
module, conga-CEVAL and conga-Cdebug carrier boards, CRT monitor, SATA drive, and USB keyboard. When using the conga-Cdebug, the
SATA drive was powered externally by an ATX power supply so that it does not influence the power consumption value that is measured for
the module. The USB keyboard was detached once the module was configured within the OS. The module was first inserted into the conga-
Cdebug, which was powered by a Direct Current (DC) power supply set to output 12V. The current consumption value displayed by the DC
power supply’s readout is the value that is recorded as the power consumption measurement for Desktop Idle, 100% Workload and Standby
modes. The power consumption of the conga-Cdebug (without module attached) was measured and this value was later subtracted from the
overall power consumption value measured when the module and all peripherals were connected. All recorded values are approximate.
The conga-Cdebug does not provide 5V Standby power therefore S3 mode was measured using the conga-CEVAL powered by an ATX power
supply with a multimeter attached to the 5V Standby power line. The 5V Standby power consumption of the conga-CEVAL (without module
attached) and all peripherals connected was first measured and the resulting value was later subtracted from the overall S3 power consumption
value measured when the module was attached. All S3 recorded values are approximate.
The module was measured while running Windows XP Professional with SP2 (service pack 2) and the “Power Scheme” was set to “Portable/
Laptop”. The screen resolution was set to 800x600 32bit High Color. The conga-CLX was tested while using a swissbit

memory module. Using different sizes of RAM will cause slight variances in the measured results.
