Electrical Specification
2.4.1.
Power Supply Voltage Specification
The COMe-mAL10 supports operation in both single supply power supply mode and ATX power supply mode.
The following table lists the power supply voltage specifications.
Supply Voltage (VCC)
12 V
Standby Voltage
5 V ±5 %
Supply Voltage Range (VCC)
4.75 V to 20 V
RTC
2.8 V to 3.47 V
5V Standby voltage is not mandatory for operation.
2.4.1.1.
Power Supply Rise Time
The input voltage rise time is 0.1 ms to 20 ms from input voltage ≤10 % to nominal VCC. To comply with the ATX
specification there must be a smooth and continuous ramp of each DC input voltage from 10 % to 90 % of the DC input
voltage final set point.
2.4.1.2.
Power Supply Voltage Ripple
The maximum power supply voltage ripple and noise is 100 mV peak-to-peak measured over a frequency bandwidth
of 0 MHz to 20 MHz.
2.4.2.
Power Management
Power management options are available within the BIOS setup. The COMe-mAL10 implements the Advanced
Configuration and Power Interface ACPI 5.0 hardware specification to control typical platform features such as power
button and suspend states.
If VCC power is removed, 5 V ±5 % can be applied to the V_5V_STBY pins to support the following suspend-states:
Suspend-to-Disk (S4)
Suspend to RAM (S3)
Soft-off state (S5)
The Wake-up event (S0) requires VCC power because the board is running.
