Eletter Product

XMC730The XMC730 provides flexible, high-density I/O with high-performance DMA to solve a variety of SWaP-challenges.


Acromag expands their general purpose I/O offering with an XMC version of their very popular PMC730 multi-function I/O module. The XMC730 performs analog input, analog output, digital I/O and counter/timer functions. Three models provide front 68-pin SCSI-2 I/O connection or rear P16 and P4 I/O connectors. These boards are designed for commercial off-the shelf (COTS) applications providing an abundance of I/O options to save I/O slots. A variety of carrier cards are available to host up to two XMC730 modules on VPX or PCI Express computer platforms. A conduction-cooled version is also offered, and boards start at less than $1,800.

I/O options includes 16 differential or 32 single-ended analog inputs, eight analog output channels, 16 bidirectional input/output channels and 32-bit multi-function counter/timers. The DMA transfer support moves data between module memory this frees the CPU from the burden of moving data between Module memory and System memory over the PCIe bus.

“With the ever-increasing use of 3U and 6U VPX, we saw the need to re-invent the PMC730 card in an XMC version,” stated Russ Nieves, Acromag’s Vice President of Sales. “This allows customers to take advantage of increasing speed requirements, but still maintain the flexible I/O configurations that the XMC730 will offer them at a very affordable price.”

For connectivity with real time software application programs, Acromag offers C libraries for VxWorks®, Linux®, and Windows DLL Driver software. The libraries provide generic routines (source code included) to handle reads, writes, interrupts, and other functions. Demonstration programs enable the developer to quickly exercise the I/O modules before attaching the routines to the application program. This diagnostic tool can save hours of troubleshooting and debugging.
