COMEX-IE38 has multiple power supply options:
+5VSBY is always available and +VCC is supplied through S3. All working states provided by COMEX-IE38 are supported with this configuration (S0/S3/S5).
Single + VCC is always available. All working states provided by COMEX-IE38 are supported with this configuration (S0/S3/S5).
Single + VCC is supplied through S0. In this case only S0 state is supported.

System Logic
Power Control
The power control signals of the COMEX-IE38, available for the carrier board, include:
PWRBTN# / SLEEP# (Module Input): The power button signal is an ACPI standard. It has a 16 milliseconds de-bounce circuit at the PCH, and may initiate a power event, depending on the software. At any power state, if PWRBTN# is held low for at least four seconds, the system should be immediately powered off (G2/S5 state).
SYS_RESET# (Module Input): The system reset signal has a 16 milliseconds de-bounce circuit at the PCH. At falling edge of SYS_RESET#, after de-bouncing, the system should wait up to 25 milliseconds for the SMBus to go idle, and then initiate a system reset.
CB_RESET# (Module Output): The Carrier Board reset signal originates from the
PCH, and generates a reset for all the subsystems on the module. It is asserted at
PWR_OK low input, at a watchdog timeout, after a SYS_RESET# event, or by the software.
PWR_OK (Module Input): The power OK signal indicates to the module that the main power supply is within specification. It can be held low by the carrier board in order to delay the startup of the module. After pulled up by the carrier, PWR_OK must be left up as long as the main power supply is within specification.
SUS_STAT# (Module Output): The suspend status signals indicates peripheral devices that the system should switch into a sleep mode, at least 210 microseconds later.
WAKE0# (Module Input): The wake signals are indicates the PCH that a PCIe Device generated a wake event. Upon a falling edge, the system should wake up to S0 operation mode.
SPI Boot
The COMEX-IE38 SPI bus can used in order to boot from an external SPI flash device.
When BIOS_DIS1# pin is pulled to GND, external SPI Flash device is selected as boot source.
When BIOS_DIS1# is pulled-up or left unconnected, COMEX-IE38 will boot from the onboard
SPI flash.
RTC
COMEX-IE38 features an RTC with internal CMOS memory backed up by an external battery via the +VRTC pin on the COM Express connector:

COMEX-IE38 may operate in RTC-less mode (without battery back-up), saving all main parameters in the BIOS SPI flash. Date and time information is not saved in this mode.
System LEDs
COMEX-IE38 features two on-board LED indicators with the following behavior:
Green- The system is in the ON state
Red - SATA activity LED

6.1 Carrier Board Connectors Pin-out
The COMEX-IE38 connects to a carrier board with 2x110 pin connector. The pin numbering is divided to two groups: A, B, where each pin number starts with the letter of the row it's in.
The pin-out of the connectors is compatible to type 10 COM Express specifications.
Each described signal can be one of the following types. Signal type is noted in the “Signal description” tables. Multifunctional pin direction, pull resistor and open drain functionality
may be software controlled. The “Type” column header for multifunctional pins refers to
the recommended pin configuration with regards to the discussed signal.
“I” – Digital Input
"O" – Digital Output
“IO” – Digital Input/Output
"PU33SPI" – Always pulled up to 3.3V SPI power rail.
"PU33" – Always pulled up to 3.3V on-board COMEX-IE38
"PD" - Always pulled down on-board COMEX-IE38
"NC" – Connector Pin is Not Connected
"PI" – Power input pin ( to COMEX-IE38)
"PO" – Power output pin ( from COMEX-IE38)
“G” – Ground pint

Carrier Board Interface
Mating Connectors
COMEX-IE38 should be connected to a carrier board using one 110x2 pins, 0.5mm pitch connector. The connector on the carrier board should be Foxconn QT002206-2141-3H for 5mm stack, Foxconn QT002206-4131-3H for 8mm stack, or other compatible connectors.

Heat Spreader and Cooling Solutions
CompuLab provides COMEX-IE38 with a dedicated heat-spreader assembly. The COMEX-
IE38 heat-spreader has been designed to act as a thermal interface and should be used in conjunction with a heat-sink or an external cooling solution.
External cooling must be provided to maintain the heat-spreader at proper operating temperatures. The cooling solution must ensure that under worst-case conditions the temperature on any spot of the heat-spreader surface is maintained according to the COMEX-IE38 temperature specifications.
Various thermal management solutions can be used with the heat-spreader, including active and passive approaches.
Reference cooling solutions are provided by CompuLab.
Documentation and CAD drawings for the COMEX-IE38 heat-spreader and cooling solutions are provided at http://www.compulab.co.il/products/com-express/comex-ie38/#devres .

Temp. Description
0 to 70 C
Sample boards from each batch are tested for the lower and upper temperature limits. Individual boards are not tested.
-20o to 70o C Every board undergoes a short test for the lower limit (-20o C) qualification.
-40 to 85 C
Every board is extensively tested for both lower and upper limits and at several midpoints.
