VME CARD DETAILS

Three basic VMEbus card [Dimensions] sizes are shown above, which include 9U, 6U, and 3U. Two 6U card sizes are depicted.The VME64 spec added the P0 connector between P1 and P2 on the 6U size card (not shown).IEEE 1101.1 Base Document for Mechanics ~ Defines 3U/6U/9U (high) x 100/160/220/280/340/400mm (Long) cardsIEEE 1101.10 Mechanics for VME Boards and SubracksIEEE 1101.11 Mechanics for Rear Transition ModulesThree card heights are allowed with VME; 3U, 6U, or 9U; a single slot card is 6T wide. Length is either 160mm or 340mm (Norm)Height is given in 'U' [1U = 43.60mm], Length is given in 'mm', Width is given in 'T' or HP [1HP = 5.08mm [HP: Horizontal Pitch];Card sizes listed below are one slot or 6T wideA size CCA dimensions = 3U x 160mm. A 3U Printed Wiring Board [PWB] is 100mm high.B size CCA dimensions = 6U x 160mm. A 6U Printed Wiring Board [PWB] is 233mm high.C size CCA dimensions = 6U x 340mm, ... {H x L x W {@ width=6T}D size CCA dimensions = 9U x 340mm. A 9U Printed Wiring Board [PWB] is 360mm high.A, B, C, and D are VXI terms. VME normally only references 3U or 6U [dimensions] by a length.The board thickness for VME cards is 0.063 +/- 0.008 inchs [1.6mm +/- 0.2mm] Thicker or thinner CCAs may not fit in the card guides correctly.How ever an 0.90 board may work if you mill down the top and bottom [2.5mm] of the card to 0.63 so it fits in the card guides.A, B, C, and D are VXI terms. VME normally only references 3U or 6U by a length, but the 9U was added a few years ago.The VMEbus PWB Dimensions [size] or form factor is also called the Euro-card form factor.

The Diagram above provides a number of VMEbus connectors, including 3 x 32 pins 5 rows x 32 pins and a number of P2 Split Pin Coax types.There are a number of different types:P1 and P2 are 96 pin DIN (41612, Type C) 3 rows x 32 pins [Pitch 2.54mm (.100")] @ IEEE 1014-1987P1 and P2 are 160 pin DIN (41612, Type C Expanded) 5 rows x 32 pins [Pitch 2.54mm (.100")] @ ANSI/VITA 1-1994P2 is a Split DIN / RF Coax (DIN 41612 Type M) DIN + Coax @ 78 + 2, 60 + 4, 42 + 6, 24 + 8P0 is a 95 pin 2mm 5 rows x 19 pins (IEC 1076-4-101), PCI Style @ VITA 1.1-1997The class of connectors determines the number of insertions it's designed to handle per DIN 41612 [Mechanical Endurance]. DIN connectors may be purchased in one of three classes:Class 1: 500 mating cyclesClass 2: 400 mating cyclesClass 3: 50 mating cycles
