CompactPCI P2 Pinout

The CompactPCI pinout for P2 [J2] is provided below. cPCI is electrically identical to the PCI specification, it uses the same signals [not the same pinout]. However, some new signals have been added in addition to the PCI specification. cPCI uses pin/socket connectors, while PCI uses Finger/slot connectors. The number sign in the pinout table below refers to: "A # symbol at the end of a signal name indicates that the signal’s asserted state occurs when it is at a low voltage. The absence of a # symbol indicates that the signal is asserted at a high voltage. The V(I/O) pins are un-named in this table. In a +5 volt system the V(I/O) pins are +5volts, in a +3.3volt system the V(I/O) pins are +3.3 volts. The pin out for the P1 connector is listed on the cPCI P1 Pinout page.

cPCI uses 2mm 'Hard Metric'; IEC 1076-4-101, a number of different pin arrangements. Normally the outside Ground rows (which are compression pins) 'Z' and 'F' are not counted as pins. OEM pin numbering may be by cPCI or in accordance with IEC 61076-4-101 (which is reversed). The term "Hard Metric" only means that metric dimensions are preferred ~ with-out regard to inches.

cPCI 2mm connectors mating distances [12.50mm] matches the 96 pin DIN 41612 connectors used with other EuroCard packaging [IEC 273 or IEEE 1101, 1101.10], like VMEbus. FutureBus connectors, which also use 2mm style has a mating distance of 10mm, and is not compatible with cPCI connectors.

The connector types below are counting signal pins (not the ground rows), as indicated on many data sheets:

Type A connector; 110 pins, Keyed (J1/J4),([25 rows x 5 columns] - [3 rows x 5 columns of Key])
Type B connector; 110 pins (J2/J5), [22 x 5]
Type B connector; 95 pins (J3), [19 x 5]. This is also used as P0 with VME64
Type C connector; 55 pins [11 x 5]
Type AB; 95, 110, or 125 pins

There are other types:
Type L connector; # contact cavities to accept power insert contacts
Type M connector; # contact cavities to accept power insert contacts/with half the connector having normal pins.
