Acromag Releases First QMC I/O Modules and Carrier Cards for New VITA 93 Small Form Factor Mezzanine Standard
April 29, 2025 - Wixom, MI - Acromag announces the launch of its new line of VITA 93 QMC mezzanine modules, a rugged family of high-density I/O solutions designed to meet the needs of today’s embedded computing systems. Built for flexibility and high performance, these modules are ideal for aerospace, defense, industrial automation, transportation, and scientific research applications that demand reliable signal processing in a format optimized for size, weight, power, and cost (SWaP-C) limitations.
The first units released in the QMC Series feature a variety of I/O functions and a carrier card, including:
· QMC350: Analog input module with 20 channels performing 1MSPS 16-bit A/D conversion
· QMC440: Digital input module featuring 32 optically-isolated channels with interrupts
· QMC450: Digital output module providing 32 isolated solid-state relays for AC/DC switching
· QMC510: Octal serial communication module programmable for RS-232/422/485 interfaces
· QMC520: Quad isolated serial communication module with RS-232/422/485 ports
· QMC730: Multi-function I/O module combining analog I/O, digital I/O, and counter/timers
· QPCe7210: PCIe half-length carrier card
“These VITA 93 QMC modules are engineered to meet increasing demands for smaller form factors and more performance,” explained Robert Greenfield, Acromag’s Business Development Director. “At less than quarter the size of a PMC/XMC module and offering much higher performance than mini PCIe, QMC modules are ideal for smaller computers used in unmanned vehicles and narrow payload tubes.”
The VITA 93 mezzanine specifies two 80-pin connectors, for separate host and I/O interfaces, on a 26 x 78.25 mm single-width QMC module. The host connector can support PCIe Gen 4 x4 interfaces, while the I/O connector provides up to 20 differential or 40 single-ended signals arranged in five IOPipes.
Designed for versatility, QMC modules can mount on 3U/6U Eurocards like VPX and CompactPCI-Serial, PCIe expansion cards, or small form factors such as VNX+ and custom embedded PCs. The VITA 93 specification ensures compatibility between compliant modules and carriers to encourage a broad ecosystem of solutions from many vendors. Conduction-cooled systems are supported by adding a standardized, skyline heat sink to modules. An intelligent platform management interface (IPMI) allows smart carrier cards to read module information and sensor data from EEPROM over an I2C interface.
Acromag’s Universal Software Design Suite (USW-API) facilitates application development for streamlined integration with VxWorks®, Windows®, and Linux® operating systems. The API provides a library of function routines as a starting point developers can use for their customized programs.
