COM Express Architecture
The COM Express specification was developed by the PCI Industrial Computer Manufacturing Group
(PICMG) in close collaboration with many leading companies across the embedded industry in order to find
an implementation solution to handle upcoming new high speed serial I/Os, processors, and chipsets. COM
Express specifies three form factors, as well as five different types of connector pinouts.
The three form factors are referred to as Compact, Basic, and Extended. The Compact form factor is
95mm x 95mm designed to match the requirements of small applications. The Basic module footprint is
125mm x 95mm and focuses on space-constrained, low power systems which typically do not contain more
than one horizontal mounted SODIMM. The Extended footprint is slightly larger at 155mm x 110mm and
supports up to two full-size, vertically mounted DIMM modules to accommodate larger memory
configurations for high-performance CPUs, chipsets and multiprocessor systems. The placement of the
shielded 220-pin connectors and the mounting holes are identical between these three footprints.

Product Description
The Express-CBR is an exceptionally high integration, high performance, rugged Intel Core™ i7 processor
based system compatible with the COM Express standard. This rugged and high quality module system
contains all the component subsystems of an ATX motherboard.
The Intel Core i7 incorporates a dual processor core with an integrated Graphics and Memory Hub (GMH),
providing a low-power, high-performance processor, a memory controller for up to 8GB of SODIMM
memory, and a graphics controller for LVDS, VGA, and PCI Express graphics (PEG) signals.
The Intel BD82QM57 chipset provides controllers for the Platform Controller Hub (PCH) featuring eight
USB ports, four SATA ports, eight GPIO ports, one Ultra DMA 33/66/100 IDE controller supporting two
IDE drives, and one Gigabit Ethernet interface (external magnetics required).
Expansion for additional system functions is possible on the Express-CBR through the PCI, PCIe, and LPC
expansion buses. The PCI bus operates at a clock speed of 33MHz.
The Express-CBR is particularly well suited to either embedded or portable applications and meets the size,
power consumption, temperature range, quality, and reliability demands of embedded system applications.
