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.
