Connector Pinout for Compact PCI (Peripheral Component Interconnect)

The cPCI bus uses 8, 16, 32, or 64 bit transfers with up to 532MBps. This device is based on a 3U or 6U Eurocard industrial computer where all boards are connected via a passive PCI backplane.

The 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. 6U boards have an additional 220 pin connector. This connector is intentionally undefined at this time. It is used for a variety of purposes.
