Power Management

1.3.10.1 Power Supply
Supports both ATX and AT power modes. VSB is for suspend power and can be an
option if the user does not require standby (suspend-to-RAM) support. RTC Battery
may be an option if keeping the time/date is not required.
VCC: 9V ~ 12V (+/-5%) power input

VSB: 5V (+/- 5%) Suspend power

RTC Battery Power: 2.0 ~ 3.3V

1.3.10.2 PWROK
Power OK comes from the main power supply. A high value indicates that the power
is good. This signal can be used to hold off module startup to allow carrier-based
FPGAs or other configurable devices time to be programmed.
1.3.10.3 Power Sequence
According to PICMG COM Express R3.0 specifications
1.3.10.4 Wake Event
Diverse wake-up events support different scenarios.
Wake-on-LAN(WOL): Wake to S0 from S4/S5

USB Wake: Wake to S0 from S4

PCIe Device Wake: depends on user inquiry and may need customized BIOS

LPC Wake: depends on user inquiry and may need customized BIOS

1.3.10.5 Advantech S5 ECO Mode (Deep Sleep Mode)
Advantech iManager provides additional features that allow systems to enter a very
low suspend power mode – S5 ECO mode. The module will cut all power including
suspend and active power into the chipset and keep an on-module controller active in
this mode. In such cases, under 50mW power will be consumed. This means user-
battery packs can last longer. When enabled in BIOS, this mode only allows the sys-
tem (or module) to power button boot, and does not support WOL.
