Electrical Specification
2.4.1.
Power Supply Voltage Specifications
The COMe-bKL6 supports operation in both single power supply mode and ATX power supply mode.
Industrial temperature grade modules are validated for 12 V power supply only.
Commercial temperature grade modules support the wide range 8.5 V to 20 V power supply.
The following table lists the power supply specifications.
Supply Voltage Range (VCC)
8.5 V – 20 V
Supply Voltage (VCC)
12 V
Standby Voltage
5 V ± 5% ( 5 VSB is not mandatory for operation)
RTC
2.8 V to 3.47 V
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 is 100 mV peak-to-peak at 0 MHz – 20 MHz.
2.4.2.
Power Management
Power management options are available within the BIOS setup.
ACPI Settings
ACPI 5.0
Miscellaneous Power
Management
Supported in BIOS setup menu
Within the BIOS setup, 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 RAM (S3)
Suspend-to-disk / Hibernate (S4)
Soft-off state (S5)
The Wake-up event (S0) requires VCC power as the board is running.
