IEEE Standard for a Common Mezzanine Card (CMC) Family and IEEE Standard Physical and
Environmental Layers for PCI Mezzanine Cards (PMC)

Abstract: The mechanics of a common mezzanine card (CMC) family are defined in this standard.
Mezzanine cards, designed to this standard, can be used interchangeably on VME, VME64 and
VME64x boards, CompactPCI? boards, Multibus? I and II boards, desktop computers, portable
computers, servers, and other similar types of applications. Mezzanine cards can provide modular
front panel I/O, backplane I/O or general function expansion or a combination for host computers.
Single, wide mezzanine cards are 75 mm wide by 150 mm deep by 8.2 mm high.
