Upgrade to the Mercury SA1

If you want to upgrade your current Mercury CA1 solution, then have a look at the Mercury SA1.


The Mercury CA1 module offers high-performance yet low cost Intel Cyclone IV FPGAs in conjunction with standard interfaces like USB 2.0 and Gigabit Ethernet.

With its powerful standard interfaces, the many LVDS capable I/Os, the large DDR2 SDRAM and the many hardware multipliers it is equally suited for digital signal processing, networking, high-speed I/O as well as SoPC applications utilizing the Intel Nios® II soft processor.

The Mercury CA1 FPGA board reduces development effort, redesign risk and improves time-to-market.


  • Features the latest Intel low-cost FPGA family
  • FTDI-based USB 2.0 High-Speed interface
  • Gigabit Ethernet PHY for high-bandwidth/low-latency networking
  • Smaller than a credit card
  • Only requires a single supply voltage (5..15V)


  • Vast amount of parallel processing power for DSP applications (up to 200 multipliers at 260 MHz = 52 GMAC/s)
  • High-bandwidth data I/O due to the large number of available LVDS pairs
  • Simple and low-cost integration due to standard interfaces (USB, Gigabit Ethernet), single supply voltage and 2.5V / 3.3V power outputs
  • Simplified carrier board design (typically 4 layers)
  • Many IP cores are available from Intel, Enclustra and third parties


  • Intel Cyclone IV E FPGA
  • Small form factor (56 x 54 mm, dual 168-pin Hirose FX10 connectors)
  • 25 differential pairs and 98 single-ended user I/Os or 146 single-ended user I/Os (168 with custom configuration)
  • 16 MB SPI Flash
  • Up to 256 MB DDR2 SDRAM
  • FTDI USB 2.0 High-Speed interface
  • Gigabit Ethernet PHY
  • High-power 8A core power supply
