CompactPCI bus

pinout

PCI=Peripheral Component Interconnect. CompactPCI is a version of PCI adapted for industrial and/or embedded applications.

7x47 pin (IEC917 and IEC1076-4-101)
7x47 pin (IEC917 and IEC1076-4-101) connector  at the backplane (is numbering correct?)

CompactPCI is an adaptation of the Peripheral Component Interconnect (PCI) Specification for industrial and/or embedded applications requiring a more robust mechanical form factor than desktop PCI. CompactPCI uses industry standard mechanical components and high-performance connector technologies to provide a system optimized for rugged applications.

cPCI is electrically identical to the PCI specification (except it uses the Euro (VME) card 3U/6U format with 2mm connectors), allowing low-cost PCI chipsets to be utilized in a mechanical form factor suited for rugged environments. The cPCI bus uses 8, 16, 32, or 64 bit transfers with up to 532MBps. The CompactPCI specification accommodates a methodology for live insertion and removal of adapters.

3U CompactPCI boards use a single 220 pin connector for all power, ground, and all 32 and 64 bit PCI signals. This connector is called J1. Twenty pins are reserved for future use. Backplanes use male (pin) connectors and plug-in boards use female (socket) connectors. Plug in boards that only perform 32 bit transfers can use a smaller 110 pin connector. 32 bit boards and 64 bit boards can be intermixed and plugged into a single 64 bit backplane.

6U boards have an additional 220 pin connector. This connector is intentionally undefined at this time. It is used for a variety of purposes. It can be used as a bridge to other buses like VME or ISA. These "hybrid" backplanes use CompactPCI for the processor and high speed peripheral section and one of these industrial buses for an I/O expansion section.

Overview:

A CompactPCI system is composed of up to eight CompactPCI card locations:

  • One System Slot
  • Up to seven Peripheral Slots

The connector has 7 columns with 47 rows. Normally the outside ground rows "Z" and "F" are not counted as pins. Pins are divided into groups:

  • Row 1-25: 32-bit PCI
  • Row 26-47: Additional pins for 64-bit PCI (System Slot boards must use it).
  • Row 26-28 and 40-42: Primarily implemented on System Slot boards.
