PCI-SIG specifications define standards driving the industry-wide compatibility of peripheral component interconnects. Members regularly review them, providing commentary and change requests when necessary. These requests are considered by technical workgroups and applied as appropriate, resulting in collaboratively devised specifications benefiting millions of platforms and add-in devices.
PCI-SIG members may access specifications online, at no cost, using the Specification Library. Members may filter their search by technology type, revision, and the type of document. Select the appropriate filters and then select the Filter button to initiate your search. Alternatively, members may purchase a hard copy of the specifications, at a reduced member rate, here.
Non-members who are interested in purchasing specifications may submit their order here.
