Computer-On-Modules Focus on your Core Competency The COM Express Standard – A Computer-On-Module (COM) provides a convenient solution for Adaptable to Your Specific Needs OEMs that need computing functionality but are not interested in COM Express was developed and is maintained by PICMG investing the time and resources into designing a single board (PCI Industrial Computer Manufacturers Group). COM computer. There are several COM standards, one of the more Express was released in the summer of 2005 and is the popular being COM Express (also referred to as COM.0). COM most widely used COM standard. The standard defines the Express modules contain the CPU, memory, common peripherals physical size, interconnect, and thermal interface for a COM. (USB, SATA) and an I/O interface (PCI and PCI Express). OEMs that The original COM Express specification was written to use COM Express modules design a carrier board that contains any support peripherals that were available at the time of release required I/O interfaces not found on the COM Express module as – including USB 2.0, SATA, PATA, Ethernet, VGA, LVDS, well as connectors for external I/O. A COM based solution allows SDVO, PCI, and PCI Express Gen 1. Several pinout types an OEM to focus on their core competency and not the design and were defined by PICMG with each one having a specific maintenance of a single board computer. combination of peripherals, expansion interfaces and connector layout. The most widely used COM Express A COM Express based solution with a custom carrier board offers module is a type 2, followed by type 1. The table on the several advantages: following page shows the features for modules defined in • The carrier can contain more rugged types of connectors for revision 1 of the COM Express specification. external I/O. It is not limited to traditional connectors such as USB, Ethernet, and video. COM.0 Rev. 2.0 – Future Proof • The carrier can contain value added silicon such as FPGAs or other In 2009, PICMG formed a subcommittee to update the COM types of peripherals. Placing these devices on the carrier Express specification based on the changes in peripherals eliminates the need for traditional PCI Express or PCI expansion used in modern systems. This included support for Super cards and the mechanics associated with them. Speed USB 3.0, PCI Express Gen 2 signaling, as well as • The CPU function is decoupled from the I/O so that different additional video interfaces such as DVI, HDMI and processors can be used for different applications, ranging from low DisplayPort. The spec update created two new types to power and cost Atom™ based compute modules to Core™ i7 or support the I/O changes: type 6 and 10.
