Advanced Mezzanine Card
Advanced Mezzanine Cards are printed circuit boards (PCBs) that follow a specification of the PCI Industrial Computers Manufacturers Group (PICMG). Known as AdvancedMC or AMC, the official specification designation is AMC.x. Originally AMC was targeted to requirements for carrier grade communications equipment, but later used in other markets.
AMC modules are designed to work standalone, hot pluggable on any carrier card (base boards and system carrier boards in AdvancedTCA Systems) or as a hot pluggable board into a backplane directly as defined by MicroTCA specifications. The AMC standard differs from other mezzanine card standards such as PCI Mezzanine Card (PMC), PCIexpress Mezzanine Card XMC and FMC – FPGA Mezzanine Card by the 0 degree instead of 90 degree orientation of its connector enabling hot plug of the AMC.
