End-Of-Life – EOL

This product is EOL and will be no longer available after stock depletion.

Upgrade to Xilinx Artix-7

If you need a more powerful FPGA module or want to upgrade your current Xilinx Spartan-6 solution, then have a look at the Mars AX3.


The Mars MX1 FPGA module is equipped with fully EtherCAT-compliant dual Fast Ethernet PHYs and fast DDR2 SDRAM. It is thus perfectly suited for compact SoPC systems based on the Xilinx Microblaze soft processor communicating via real-time field buses.

The SO-DIMM form factor allows space-saving hardware designs, and quick and simple integration of the FPGA board into the target application.



  • Low-cost, low-power FPGA
  • Uses the widely-supported and compact SO-DIMM form factor
  • Available with different FPGA densities
  • Available in industrial temperature range
  • Dual Fast Ethernet for Industrial Ethernet like PROFINET, EtherCAT, POWERLINK or Ethernet/IP
  • Powerful and compact FPGA board


  • Simple, low-cost and rugged assembly, in the industry-standard SO-DIMM form factor
  • Fast boot times and support for execution-in-place (XiP) due to the 4 bit parallel SPI Flash
  • Lowest power consumption due to the high-efficiency DC/DC converters and support for SUSPEND.
  • Many IP cores are available from Xilinx, Enclustra and 3rd parties.


  • Xilinx Spartan-6 LX FPGA
  • SO-DIMM form factor (67.6 x 30 mm, 200 pins)
  • 108 user I/Os, single-ended or differential
  • 16 MB quad SPI Flash
  • Up to 256 MB DDR2 SDRAM
  • Dual Fast Ethernet PHYs (fully EtherCAT-compliant)
  • Real Time Clock (± 5 ppm, with temperature sensor)
  • Single 3.3V supply voltage

Mars Heat Sink

Mars Heatsink (Top)

The Mars heat sink is an optimal solution to cool the Mars MX1 – it's low profile (less than 7 mm tall) and covers the whole module surface. It comes with a gap pad for the FPGA and four screws to attach it to the module PCB. With additional user configured gap pads, it is possible to cool other components on board as well.
