New revision of COM Express specification

27 June 2012 News

PICMG, a leading standards organisation for the communications, military and embedded computer industries, has announced the adoption and availability of the COM Express Revision 2.1 specification.

The original computer-on-module (COM) Express specification, adopted by PICMG in 2005, was designed to reduce time-to-market on specialised platforms used in industrial, medical, military, scientific and telecommunication applications. COM Express puts all compute functions on small modules that can be used standalone or plugged onto a base board with application-specific I/O.

The COM Express Revision 2.1 specification allows developers to focus on their specialised I/O requirements, without concern for the complex interactions of CPUs, RAM, chipsets and other basic elements that occur on the module. This revision adds new features and module sizes, and helps ensure that COM Express modules are prepared for future processors and high-speed I/O evolution, while accommodating backward compatibility with older modules.

Significant enhancements include standardisation of new and smaller module sizes, extended power supply range, latest graphics interface support, USB 3.0 support and CAN-bus support.

The new specification is available in print and electronic formats, and can be purchased at www.picmg.org/v2internal/specorderformsec.htm
