Alt for EP1K50TI144-2N

Hi All, I need an alternative FPGA for the EP1K50TI144-2N That does not require major changes to the firmware code ,which family would easier to migrate to the obsolete EPF10K10AQI208-...

    Nope, you are stuck with the EP1K50 series if all you have is a .pof file. Any temp grade, any speed grade will suffice.

    You need the source code to migrate to any other device (or even a different size of the EP1K series) to do a recompile.

    So unless you can come up with the source code you are going to be stuck sourcing EP1K50's from brokers.

Surely you'll go for MAX 10, only problem could be missing 5V tolerance of MAX 10 inputs.

EPF10K is by the way a 5V device and can't replace 3.3 V ACEX 1 series.

    Hi FvM,

    While my FPGA on the board is using 2.5 and 3.3 v ,I am able to source both 5 and 3.3 V for the inputs, if need be ,they are available on the PCB,my concern is which of the 2 will require less code changes and schematic capture and layout rerouting.

      Since EP1K50TI144-2N is in stock, why does it need to be modified? Replacing it is a very painful thing

        Hi,

        I am actually trying to avoid replacing the chip but its obsolete and can only be purchased from brokers.
