Advantech warrants the original purchaser that each of its products will be free from
defects in materials and workmanship for two years from the date of purchase.
This warranty does not apply to any products that have been repaired or altered by
persons other than repair personnel authorized by Advantech, or products that have
been subject to misuse, abuse, accident, or improper installation. Advantech
assumes no liability under the terms of this warranty as a consequence of such
events.
Because of Advantech’s high quality-control standards and rigorous testing, most
customers never need to use our repair service. If an Advantech product is defective,
it will be repaired or replaced free of charge during the warranty period. For out-of-
warranty repairs, customers will be billed according to the cost of replacement mate-
rials, service time, and freight. Please consult your dealer for more details.
If you believe your product to be defective, follow the steps outlined below.
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen messages displayed when the prob-
lem occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain a return merchandise authori-
zation (RMA) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a completed Repair and Replacement
Order Card, and a proof of purchase date (such as a photocopy of your sales
receipt) into a shippable container. Products returned without a proof of pur-
chase date are not eligible for warranty service.
5. Write the RMA number clearly on the outside of the package and ship the pack-
age prepaid to your dealer.

ital device, pursuant to part 15 of the FCC Rules. These limits are designed to pro-
vide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. However, there is no guarantee that interfer-
ence will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:
Reorient or relocate the receiving antenna.

Safety Precautions - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from the PC chassis
before manual handling. Do not touch any components on the CPU card or
other cards while the PC is powered on.
Disconnect the power before making any configuration changes. A sudden rush
of power after connecting a jumper or installing a card may damage sensitive
electronic components.
Warning! Warnings indicate conditions that could cause personal injury if not
observed!
Caution! Cautions are included to help prevent hardware damage and data loss.
For example,
“Batteries are at risk of exploding if incorrectly installed. Do not attempt
to recharge, force open, or heat the battery. Replace the battery only
with the same or equivalent type as recommended by the manufacturer.
Discard used batteries according to the manufacturer's instructions.”
Note! Notes provide additional and/or optional information.

SOM-7532 User Manual 2
1.1 Introduction
SOM-7532 is a COM Express Compact module with type 10 pin-out that fully com-
plies with the PICMG (PCI Industrial Computer Manufactures Group) COM R3.0
specification. The CPU module is Intel® Pentium®/Celeron® and Atom® x6000 Series
Processors (formally called Elkhart Lake) in a mini size 55x84mm COM Express form
factor, features a 12watt thermal design power (TDP) rating.
Compare with previous platforms, SOM-7532 has a better 1.7X CPU performance,
and 2X graphics performance enhancements. SOM-7532 supports up to 16GB dual
channel LPDDR4 3200MT/s memory, with higher memory bandwidth for better per-
formance. In addition, there are numerous high speed I/O interfaces included, such
as PCIe Gen3 (8.0GT/s) and 2.5Gbase-T, USB3.2 Gen2 (10Gbps) and CAN-FD, for
better system expansion. Moreover, it could be developed with double independent
displays up to 4K, picked from DisplayPort 1.4/HDMI 2.0 and one optional eDP or
LVDS. With optional eMMC, TPM2.0 on-board design, 4.75~20V power input feature,
and -40 to 85°C operating temperature. SOM-7532 is a reliable and suitable solution
for industrial & automation requirements.
Advantech iManager (SUSI 4) is invented to satisfy a lot of embedded application
requirements such as multi-level watchdog timer, voltage and temperature monitor-
ing, thermal protection and mitigation through processor throttling, LCD backlight on/
off and brightness control, embedded storage for customized information, etc. Com-
bining Advantech WISE-PaaS/RMM, it can remote monitoring and controlling
devices through internet for easy maintain. All Advantech modules integrate iMan-
ager and WISE-PaaS/RMM to be an add-on value for customer’s applications.
Capable of performance under extreme conditions, and featuring embedded platform
power consumption and multiple expansion I/O interfaces, SOM-7532 is a product
that is computing centric, thermal sensitive, graphics/media insensitive, and appropri-
ate for demanding I/O applications.

Chapter 1 General Information
The standard module has no jumper at SCN1, so BIOS settings is kept without a
RTC coin battery. If you need to restore to BIOS default settings follow the steps
below:
1. Remove the coin battery.
2. Put jumper on SCN1 pin1-2.
3. Turn on power supply.
4. System will boot up a few times.
5. BIOS will be load default setting successfully.
1.3.9 Power Management
1.3.9.1 Power Supply
Supports both ATX and AT power modes. VSB is for suspended power and can be
optional if not required by standby (suspend-to-RAM) support. RTC battery may be
optional if date/timekeeping is not required.
VCC: 4.75V (5V-5%) – 20V (19V+5%)
VSB: 5V ± 5% (Suspend power)
RTC Battery Power: 2.0V – 3.3V
1.3.9.2 PWROK
Power-good from the main power supply. A high value indicates the power level is
good. This signal can be used to postpone module startup allowing Carrier-based
FPGAs or other configurable devices time to be programmed.
1.3.9.3 Power Sequence
According to PICMG COM Express R 3.0 specification.

1.3.9.4 Wake Event
Various wake event support allows users to apply different scenarios.
Wake-on-LAN(WOL): Wake to S0 from S3/S4/S5
USB Wake: Wake to S0 from S3
PCIe Device Wake: depends on user inquiry and may need customized BIOS
LPC Wake: depends on user inquiry and may need customized BIOS
1.3.9.5 Advantech S5 ECO Mode (Deep Sleep Mode)
Advantech iManager provides additional features allowing the system to enter a very
low suspended power mode – S5 ECO mode. In this mode, the module will cut all
power, including suspended and active power to the chipset, and keep an on-module
controller active. Only power under 50MW will be consumed, meaning user battery
packs can last longer. While this mode is enabled in the BIOS, the system (or mod-
ule) only allows power button boot instead of other methods such as WOL.
