The FMC (FPGA Mezzanine Card) add-on card category—governed by the ANSI/VITA 57 standards—defines a standardized, high-performance form factor for expansion modules that connect directly to FPGAs (Field Programmable Gate Arrays) or SoC carrier boards.
Unlike traditional expansion interfaces (such as PCIe or standard mezzanine cards like PMC/XMC), FMC modules bypass protocol-translation chips. Instead, they route signals directly to the FPGA’s reconfigurable I/O pins. This architecture delivers ultra-low latency, maximum bandwidth, and lower power consumption.
