COM 830 Reference Manual 7
Electrostatic Sensitive Device
All COM 830 variants are electrostatic sensitive devices. Do not handle the COM 830, or processor, except
at an electrostatic-free workstation. Failure to do so may cause damage to the module and/or processor and
void the manufacturer’s warranty.
Supply Voltage Standard Power
12V DC ± 5%
Electrical Characteristics
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 COM 830 module, Ampro baseboard, CRT monitor, SATA drive, and USB
keyboard. The complete testing environment was powered by a Direct Current (DC) power supply that is 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. All recorded values are approximate.
The power consumption of the Ampro baseboard (without module attached) was first measured and the
resulting value was later subtracted from the overall power consumption value measured when the module
and all peripherals were connected.
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.
Each module was measured while running Windows XP Professional with SP2 (service pack 2) and the
“Power Scheme” was set to “Portable/Laptop”. This setting ensures that Core 2 Duo and Core Duo
processors run in LFM (lowest frequency mode) with minimal core voltage during desktop idle. Celeron M
processors do not support this feature and therefore always run at the same core voltage even during desktop
idle. Each module was tested while using a swissbit
® DDR2 PC2-4200-444 512MB memory module. Using
different sizes of RAM, as well as two memory modules, will cause slight variances in the measured results.
Power consumption values were recorded during the following stages:
Windows XP Professional SP2
Desktop Idle (1000MHz for 667MHz FSB or 800MHz for 533MHz FSB modules)
100% CPU workload (see note below)
