PCI-SIG Delivers Latest Version of the Conventional PCI Specification with the Introduction of Version 3.0.Business Editors & Technology Writers PORTLAND, Ore.--(BUSINESS WIRE)--April 19, 2004 New specification maintains compatibility with version 2.3 and completes the migration to 3.3V-only slots The PCI-SIG(R), the Special Interest Group responsible for Conventional PCI (1) (Payment Card Industry) See PCI DSS. (2) (Peripheral Component Interconnect) The most widely used I/O bus (peripheral bus). (TM), PCI-X (PCI eXtended) An enhanced PCI bus technology originally developed by IBM, HP and Compaq that is backward compatible with existing PCI cards. PCI and 32-bit PCI-X slots are physically the same, and PCI cards can plug into PCI-X slots. (R), and PCI Express A high-speed peripheral interconnect from Intel introduced in 2002. Note that although sometimes abbreviated "PCX," PCI Express is not the same as "PCI-X" (see PCI-SIG and PCI-X for comparison). As a result of the confusion, "PCI-E" or "PCIe" is the accepted abbreviation. (TM) industry-standard I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output technologies, announced today that it has released version released version - release 3.0 of the Conventional PCI specification. Revision 3.0 is the latest version of the Conventional PCI specification that builds upon version 2.3 and completes the migration of the PCI bus from the original 5.0V (volt) signaling to 3.3V-only slots. As semiconductor signaling technologies have progressed since the 1992 release of the Conventional PCI 1.0 spec, the base signaling voltages have dropped from the standard of 5.0V to the current 3.3V. Subsequent Conventional PCI specifications, versions 2.0 and 2.3, responded to industry needs by first enabling 3.3V and then initiating the migration to 3.3V-only slots. The new Conventional PCI 3.0 spec completes the migration to 3.3V-only slots by removing support for 5.0V-only keyed add-in cards. Universal keyed add-in cards (cards that are keyed for both 5.0V and 3.3V slots) continue to be supported by the Conventional PCI 3.0 spec. Version 3.0 also incorporates the errata er·ra·ta n. Plural of erratum. and ECNs (Engineering Change Notifications) to version 2.3 specification. Version 3.0 supports multiple bus specifications: PCI 66, PCI-X, Mini PCI, and Low Profile PCI. "Conventional PCI is a mature technology that has been proven in real-life applications throughout the last decade. It has adapted to the latest market needs while preserving the backward compatibility and protecting investments that companies have made over the years. With the release of version 3.0, Conventional PCI completes the migration to the 3.3V slots which is the current industry standard," said Tony Pierce, PCI-SIG chairman. "We are proud of the contribution that PCI-SIG has made with Conventional PCI over the last 12 years." Benefits of PCI-SIG Membership Use PCI-SIG logos.

About the PCI-SIG The PCI-SIG is the Special Interest Group that owns and manages PCI specifications as open industry standards. The organization defines and implements new industry standard I/O (Input/Output) specifications as the industry's local I/O needs evolve. The PCI Special Interest Group was formed in 1992, and the organization became a nonprofit corporation nonprofit corporation n. an organization incorporated under state laws and approved by both the state's Secretary of State and its taxing authority as operating for educational, charitable, social, religious, civic or humanitarian purposes. , officially named "PCI-SIG" in the year 2000.
