PC104 Computing Standard

The PC104 Consortium was established in February 1992 based on the vision to adapt desktop computer technology for embedded applications. Although small, PC104 has proven to be simple and elegant in design, while providing rugged performance on land and space. PC104 technology merges the successes of past technologies with the confidence of future innovations.

Since its inception and adoption, the PC104 Consortium has evolved and expanded upon its original purpose. Below are descriptions of PCI/104-Express™, PC104-Plus™, and PC104 along with links to the appropriate Samtec part numbers.

PC104

The base PC104 Standard defines a compact form-factor that can be used in self-stacking buses. This eliminates the cost and bulk of backplanes and card cages.

The PC104 Standard extends upon the existing PC bus allowing companies that embed PC technology in limited space applications to have a standardized system architecture as well as a broader range of vendors and vendor support.

PC/104-Plus™

PC/104-Plus™ is a specification that was accepted in 1997 by the PC104 Consortium and establishes a standard for embedded applications with the use of a high speed PCI bus.

Like the PC104 extends upon the PC bus, the PC/104-Plus™ is an extension of the PC104 with all of the same benefits, plus more.

PCI/104-Express™

The PCI/104-Express™ specification establishes a standard to use a high speed PCI Express® bus in embedded applications.

The PC104 Consortium chose PCI Express® because of its full PC market adoption, performance, scalability, and growing silicon availability worldwide. It provides a new high-performance physical interface while retaining software compatibility with existing PCI infrastructure.
