CompactPCI is a standard in computer bus technology for industrial computing that utilizes a Eurocard type connector combined with PCI signaling and protocols. cPCI boards come in 3U and 6U variants and are typically interconnected through a passive backplane. The connector pin assignments are standardized by PICMG , allowing for eight boards in a PCI segment with multiple bus segments being allowed with the use of active bridges. 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. 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 with access on the rear or the upper 32 bits of an 64-bit PCI bus. 6U cards have an identical 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. Hot-plugging is a supported feature of CompactPCI. Some of the pins are slightly longer to provide proper grounding when devices are inserted and removed. Hartmann CompactPCI system platforms provide intelligent, practical packaging solutions for high-performance processors. Available are 19” rack and desktop models for vertical and horizontal mounting of boards. All systems are designed with enhanced EMC features, and conform to IEEE 1101.1, 1101.10/11 and IEC 60297-3-101, -102, and -103.
