FAQs

  • Are there any royalty fees for the use of an IP Core?

    There is no royalty fees associated with the use of the IP core in a customer's products. If your IP solution incorporates Microtronix an IP Core and is sold to a third party as IP for incorporation into their product they are required to purchase their own IP Core license.

  • Do you support 240 VAC input?

    Yes, we support 220 VAC power input.

  • Do you support DP3000?

    DP3000 is Datapac 3000 X.25 service, and yes we support X.25 user data and facilities.

  • Does the Multi-port SDRAM IP Core require the use of dedicated IO pins?

    The core requires use of the dedicated DQS for DDR/DDR2 memory only. Unlike most cores, the controller can use any bank of IO for the memory interface. The dedicated DQ IO pins are not required by the data, address and chip select signals.

  • Does your SDRAM Controller support multiple banks of memory?

    The current version of the memory controller supports wider memory configurations. Unfortunately it doesn't support deeper memory schemes. The controller has only one chip select. The number of devices parameter found in the SOPC Builder GUI is used in DDR mode for the DQS capture scheme. Future releases of the memory controller may support multiple chip selects.
