Zefant-nano (Virtex 4)

From $1


    Zefant-nanoV4 3D.jpgThis is our best Zefant-nano FPGA module so far. On less than 5x4cm you get a complete high end Virtex based FPGA solution. It contains Virtex-4 FX or LX FPGA, DDR2 memory, flash memory, wide range power supply and much more on a high end impedance controlled 12 layer PCB. You only need a single power supply (5...12V) to run the module, everything else is already integrated.

    Compared to the old nano-3E modules additional pins are available (100 pins per connector instead of 80), but the old connectors can optionally be occupied as well for backwards compatibility. With the new connectors the pinout has been improved a lot, more free I/Os, more differential pairs and additional physical layer pins.

    The module can be used together with the Zemu-nano Microcontroller modules, they fit on top of the module. The first "nano Universal Baseboard" is already prepared for the use of a stack of these modules as well. 



    • Stamp sized - extremely small footprint
    • Virtex-4 FX / LX based
    • 1GBit (128MByte) onboard DDR2 SDRAM 32bits wide
    • 64MBit onboard Flash Memory
    • Coolrunner 2 for configuration
    • Integrated wide range single voltage power supply
    • Stackable
    • Improved pinout and larger connectors, more I/Os, more differential pairs
    • nearly all I/Os are differential pairs
    • impedance controlled 12 layer PCB
    • optionally the old 80 pin connectors can be occupied for backwards compatibility
    • up to 3 I/O voltages available (2 externally supplied)
    • compatible with Zemu ARM7/ARM9 modules
    • wide range power supply onboard
    • Evaluation Baseboards available
