VITA 93 – QMC
The VITA 93 – QMC mezzanine card standard, under development by the VITA Standards Organization and expected to be released in spring 2025, is set to revolutionize embedded computing systems. It will bring higher bandwidth, unprecedented modularity, flexibility, and scalability, leading to enhanced system performance and adaptability.
VITA 93 – QMC cards, more compact and powerful than previous standards, offer a single design for air- and conduction-cooled systems, PCIe Gen6 up to x16, IPMI system management, and high-density I/O. Their versatility makes them ideal for a wide range of applications in industrial automation, transportation, testing, medical, and more. TEWS Technologies offers expertise in implementing these solutions with COTS, modified, or custom designs, opening up a world of possibilities.
Leveraging its expertise in PCIe-based solutions like XMC and mPCIe, TEWS Technologies wants to position itself as one of the market leaders for the new standard, building up a comprehensive product portfolio covering simple I/O to high-performance FPGAs and various carrier solutions.
For certain applications where the primary use of this might be an I/O interface, I think you can’t get much smaller than a single QMC. I would say this is pretty close to what we can expect at least for the next 10 years.
