PICMG Releases Computer-on-Module Specification for Embedded Market

COM Express defines small form factor computer module with full complement of interfaces

WAKEFIELD, Mass.--July 20, 2005--PICMG has released the COM Express Specification (COM.0) for very small form factor computer modules aimed at a wide variety of vertical applications in the embedded marketplace.

The Computer-on-Module approach puts an entire computer host-complex power on a small form factor (either 95mm x 125mm or 155mm x 110mm) module that can be mounted on larger carrier boards containing the application specific IO and power circuitry. It also allows flexibility in standard form factor boards that require upgradeable host functionality. This brings benefits to system designers, such as reduced time-to-market, cost-effective customization and lower product lifecycle costs.

COM Express supports a rich set of interfaces, including PCI Express, PCI Express Graphics, Serial ATA, Serial Attached SCSI, USB 2.0, LVDS, Serial DVO (digital video out), Ethernet, and GPIO, as well as enhanced system and power management features, making it suitable for many embedded computing applications. Support for PCI and parallel ATA further ensures that OEMs have a smooth transition path from existing systems.

The specification was developed by PICMG member companies with extensive experience in the embedded market place. The subcommittee included ADLink, Diversified Technology, Foxconn, GNP, Intel, Kontron, Maxim Integrated Products, MEN Mikro Elektronik GmbH, Microbus, PFU Systems, Radisys, SBS Technologies and Tyco.

"The specification meets the need of the embedded industry for a computer-on-module standard applicable to a wide range of form factors and which encapsulates modern, high-speed interfaces," said Kishan Jainandunsing of PFU Systems, who chaired the PICMG COM.0 Subcommittee.

The PICMG website includes a product directory where manufacturers list their PICMG compliant product offerings. These product listings can be viewed at www.picmg.org/productlistings.stm. Copies of the complete specification are available to PICMG members and can be purchased by non-members from PICMG. More information on new PICMG developments is available at www.picmg.org/picmgnewinitiatives.stm.
