CompactPCI
A CompactPCI (cPCI) system is a 3U or 6U Eurocard-based industrial computer, where all boards are connected via a passive PCI backplane. The PICMG (PCI Industrial Computers Manufacturers Group) US and PICMG Europe organizations have standardised the connector pin assignments . The connectors and the electrical rules allow for 8 boards in a PCI segment. Multiple segments are allowed with bridges.Hot-plugging is a supported feature of CompactPCI.
Unlike the original Eurocard solutions such as VME, which use connectors with a 0.1 inch (2.54 mm) pin spacing, CompactPCI cards use metric connectors with a 2-millimeter pin spacing, designed to the IEC 1076 standard. 6U cards have a J1, a J2 that is always used for 64-bit PCI, as well as J3, J4, and J5 connectors for a variety of uses either as user-defined I/O or specified signaling such as Telephony and/or Ethernet signaling. 3U boards have a 110-pin connector (J1), which carries the 32-bit PCI bus signals, and an optional 110-pin connector (J2), which carries either user-defined I/O or the upper 32-bits of an optional 64-bit PCI bus. The backplanes can be designed for 3.3V VIO or 5V VIO operation.
