HwB: CompactPCI (Tech) Connector

CompactPCI (Technical)

This section does not currently contain so much in depth information as I would like.

Since CompactPCI is based on PCI you should first refer to the PCI standard. This only explains the extensions CompactPCI specifies.

For a copy of the full CompactPCI standard, contact:

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. They 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.

The following signals must be terminated:
