Although PCI mezzanine cards (PMCs) were targeted for CompactPCI® (cPCI) and VME systems, they can be used on any form factor that provides the mechanical, electrical and signaling requirements. For example, Advanced Telecom Computing Architecture, or AdvancedTCA® carrier boards—designed for the telecommunications and data center markets—often include PMC slots to take advantage of the design flexibility of existing PMC products. In addition, a new mezzanine card, the AdvancedMC®, originally designed for AdvancedTCA systems is also being utilized on other systems.
