CompactPCI [cPCI] Board Dimensions

cPCI Connector Keying:

Either J1 or J4 may be keyed
J1: Key for either 3U or 6U cards provides for three options
.....Absent: 3.3v or 5v signaling
.....Blue: 5 volt signaling
.....Yellow: 3.3 volt signaling

J4: Key for 6U cards provides for two options
.....Red: CTBus
.....Green: VME64 Extensions

cPCI Pin-Outs P1 Signal Names, P2 Signal Names

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. Connector manufacturers [vendors] are listed on the main CompactPCI [cPCI] page.

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

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

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

cPCI and PXI use the same form factor [card size]. cPCI and PXI use the electrical bus standard of PCI [with a few changes].
