For Your Safety
Your new Kontron product was developed and tested carefully to provide all features necessary to ensure its
compliance with electrical safety requirements. It was also designed for a long fault-free life. However, the life
expectancy of your product can be drastically reduced by improper treatment during unpacking and installation.
Therefore, in the interest of your own safety and of the correct operation of your new Kontron product, you are
requested to conform to the following guidelines.
High Voltage Safety Instructions
As a precaution and in case of danger, the power connector must be easily accessible. The power connector is the
product’s main disconnect device.
Warning
All operations on this product must be carried out by sufficiently skilled personnel only.
Electric Shock!
Before installing a non hot-swappable Kontron product into a system always ensure that
your mains power is switched off. This also applies to the installation of piggybacks. Serious
electrical shock hazards can exist during all installation, repair, and maintenance operations
on this product. Therefore, always unplug the power cable and any other cables which
provide external voltages before performing any work on this product.
Earth ground connection to vehicle’s chassis or a central grounding point shall remain
connected. The earth ground cable shall be the last cable to be disconnected or the first
cable to be connected when performing installation or removal procedures on this product.
Special Handling and Unpacking Instruction
ESD Sensitive Device!
Electronic boards and their components are sensitive to static electricity. Therefore, care
must be taken during all handling operations and inspections of this product, in order to
ensure product integrity at all times.
Do not handle this product out of its protective enclosure while the product is not used for operational purposes
unless the product is otherwise protected.
Whenever possible, unpack or pack this product only at EOS/ESD safe work stations. Where a safe work station is not
guaranteed, it is important for the user to be electrically discharged before touching the product with his/her hands
or tools. This is most easily done by touching a metal part of your system housing.
It is particularly important to observe standard anti-static precautions when changing piggybacks, ROM devices,
jumper settings etc. If the product contains batteries for RTC or memory backup, ensure that the product is not placed
on conductive surfaces, including anti-static plastics or sponges. They can cause short circuits and damage the
batteries or conductive circuits on the product.

1/ Introduction
1.1. Product Description
Kontron's Computer-on-Module COMe-bCL6 is a COM Express® Basic Type 6 pinout based on the Intel® 8th/9th
Generation Core ™/Xeon® processors. The COMe-bCL6 supports additional communication interfaces via a separate
Chipset (CM246/QM370 PCH). Due to Intel’s 14nm technology, the processor offers increased efficiency and
performance with TDP as low as 25 to 45 W for quad-core chips and 25 to 45 W for six cores.
Basic COMe-bCL6 features are:
Intel® 8th/9th Generation Core series with CM246/QM370 PCH
Up to 4x DDR4-2666 SO-DIMM with up to 128 GByte (non-ECC/ECC) (3rd/4th socket on request)
High-speed connectivity includes 8x PCIe x1, 1x PEG x16, 1x 1 GbE
Support for the Industrial temperature environment
1.2. Product Naming Clarification
COM Express® defines a Computer-On-Module, or COM, with all the components necessary for a bootable host
computer, packaged as a super component. The product names for Kontron COM Express® Computer-on-Modules
consist of:
Short form of the industry standard
COMe-bCL6
Module form factor
b=basic (125 mm x 95 mm)
c=compact (9 5mm x 95 mm)
m=mini (84 mm x 55 mm)
Processor code name
CL = Coffee Lake
Pinout type
Type 6
Temperature variants
Commercial
Extended (E1)
Industrial (E2)
Screened industrial (E2S) and Rapid shutdown screened industrial (R E2S)
Processor Identifier
Chipset identifier (if chipset assembled)
Memory size
Memory Down + DIMM memory (#GB)/eMMC SLC memory (#S)
1.3. COM Express® Documentation
The COM Express® Specification defines the COM Express® module form factor, pinout and signals. The COM Express
document is available at the PICMG® website.

1.4. COM Express® Functionality
All Kontron COM Express® basic and compact modules contain two 220-pin connectors; each of which has two rows
called row A & B on the primary connector and row C &D on the secondary connector. The COM Express® Computer-
On-Module (COM) features the following maximum amount of interfaces according to the PCI Industrial Computer
Manufacturers Group (PICMG) module pinout type.

1.5. COM Express® Benefits
COM Express® modules are very compact, highly integrated computers. All Kontron COM Express® modules feature a
standardized form factor and a standardized connector layout that carry a specified set of signals. Each COM is based
on the COM Express® specification. This standardization allows designers to create a single-system baseboard that
can accept present and future COM Express® modules.
The baseboard designer can optimize exactly how each of these functions implements physically. Designers can
place connectors precisely where needed for the application, on a baseboard optimally designed to fit a system’s
packaging.
A single baseboard design can use a range of COM Express® modules with different sizes and pinouts. This flexibility
differentiates products at various price and performance points and provides a built-in upgrade path when designing
future-proof systems. The modularity of a COM Express® solution also ensures against obsolescence when computer
technology evolves. A properly designed COM Express® baseboard can work with several successive generations of
COM Express® modules.
A COM Express® baseboard design has many advantages of a customized computer-board design and, additionally,
delivers better obsolescence protection, heavily reduced engineering effort, and faster time to market.
