1.3 Introduction
COM Express™, is an open specification from the PICMG (PCI Industrial Computer
Manufacturer Group). It is a module concept to bring PCI Express and other new
technologies like SATA, USB 3.0 and different display interfaces onto a COM (Computer
On Module).
A COM Express™ module is plugged onto an application-specific base board which
provides the necessary I/O connectors and may also contain application-specific
additional logic circuitry.
Typically a COM Express module consists of CPU, chipset, memory, video controller,
Ethernet controller, BIOS Flash, SATA- and USB controller. More I/O controllers and all
I/O connectors are implemented on the base board on to which the COM Express
module can be plugged via one or two 220-pin SMD-connectors. Beside the power
supply also signals for PCIe bus, displays, SATA, USB, LPC etc. are present on these
connectors.
The type of interfaces that is led from the COM Express module to the base board
depends on the type of module that is used. The COM Express specification defines
seven different types which differ in number and pin assignment of the module
connectors.
Thanks to the standardized mechanics and interfaces the system can be scaled
arbitrarily. In spite of the modular concept the systems design is very flat and compact.
COM Express modules require a base-board for successful operation.
The base board described below acts as an evaluation board for COM Express modules
with pin-out Type 6.
2 Technical Description
