ANSI and VITA Ratify FMC ANSI/VITA 57.1-2019 FPGA Mezzanine Card (FMC) Standard

Wednesday, October 09, 2019 8:30 AM | Jerry Gipper (Administrator)

Key revisions made to improve capabilities

VITA, October 9, 2019 — VITA, the trade association for standard computing architectures serving critical and intelligent embedded computing systems markets, announces the ratification by ANSI and VITA of ANSI/VITA 57.1-2019 “FPGA Mezzanine Card (FMC) Standard”. This standard has completed the VITA and ANSI processes reaching full recognition under guidance of VITA.

ANSI/VITA 57.1-2019: FMC describes FMC IO modules and an electro-mechanical bridge between front panel IO, on the mezzanine module, and an FPGA processing device on the carrier card, which accepts the mezzanine module.

The VITA/ANSI process requires that every active standard be reviewed every five years. ANSI/VITA 57.1 was originally ratified in 2007 and revised in 2013. Changes in this revision include:

  • Added observation to account for jackscrew stand-off - miniature (JSOM) options.
  • Ground restrictions made optional for RF modules.
  • Changes to accommodate larger EEPROMs.
  • Increased 3P3VAUX maximum amps to 110mA.
  • Added observation to address FPGA power sequencing.

The FMC working group has an ongoing series of activities underway to add further capability to this popular FPGA mezzanine standard. Anyone interested in participating is invited to contact VITA for more information.

Copies of these standards are available for purchase at the VITA Online Store (
