Power
LID switch. Low active signal used by the ACPI operating system for a LID switch.
Sleep button. Low active signal used by the ACPI operating system to bring the
system to sleep state or to wake it up again.
Input from off-Module temp sensor indicating an over-temp situation.
Active low output indicating that the CPU has entered thermal shutdown.
System Management Bus bidirectional clock line.
System Management Bus bidirectional data line.
System Management Bus Alert – active low input can be used to
generate an SMI# (System Management Interrupt) or to wake the system.
Carrier Board Description
General purpose output pins.
General purpose input pins.
Carrier Board Description
Primary power input: +12V nominal. All available VCC_12V pins on the connector(s) shall be used.
The module supplies a wide range of power from 4.75V to 20.0V.
Standby power input: +5.0V nominal. If VCC5_SBY is used, all
available VCC_5V_SBY pins on the connector(s) shall be used. Only
used for standby and suspend functions. May be left unconnected if
these functions are not used in the system design.
Real-time clock circuit-power input. Nominally +3.0V.
Ground - DC power and signal and AC signal return path.
All available GND connector pins shall be used and tied to Carrier
Board GND plane.
