About Us

Founded in 1992, Peripheral Component Interconnect Special Interest Group (PCI-SIG) is an association of 700+ industry companies committed to advancing its non-proprietary peripheral component interconnect (PCI) technology by:

  • Defining PCI specifications to deliver required I/O functionality
  • Adapting PCI technology to future applications
  • Maintaining backward compatibility with previous specifications
  • Supporting industry-wide product development by offering compliance and interoperability test support

The association offers single-tiered membership, available to any company interested in developing or working with the technology. These members collaborate in open committees to define, to test and to refine specifications.

PCI-SIG’s methodical approach to specification development yields a reliable, scalable solution for high speed I/O in numerous market applications. In fact, the PCI I/O expansion bus is today’s de facto interconnect between CPUs and peripherals—in computers to servers.

As demand for higher performing I/O grows, PCI-SIG’s scope and ecosystem reach expands. Current PCI Express® and other related technology roadmaps account for new form factors and lower power applications (e.g., handhelds, mobile, IoT/embedded). Innovation on these fronts will remain true to PCI-SIG’s legacy of delivering solutions that are:

  • Backward compatible
  • Cost-efficient
  • High performance
  • Processor agnostic
  • Scalable
