Alt for EP1K50TI144-2N

[Firaseng]

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 

EPF10K10AQI208-3 

or the MAX 10?

EP1K50TI144-2N and
EPF10K10AQI208-3 is still in stock

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

[Firaseng]

Hi,

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

[Firaseng]

Microchip offers a very similar FPGA but it would probably still be a good bit of work.

Hello,

Sorry for the delay, we highly recommend you use the latest device such as MAX10 or Cyclone 10 because if you are using old devices, the technical support for the device is really limited.

Hope that helps and do let me know if I can assist you further.

Best regards,

Hello,

I only have the .pof code for my EP1K50TI144-2N,no source code,would I be able to go to a MAX10 without much issues?

[_AK6DN_ · Accepted solution]

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.

Hello again,

Is that also the case for the 

EPM7064STI100-7 CPLD?

[_AK6DN_]

The EPM7K series is a bit different, as there is a current production functional binary-compatible replacement for that part.

Intel doesn't make it, MicroChip/Atmel does as the ATF1504AS series part, in your case the ATF1504AS-10 AI100 is the closest

you can get. It is I temperature range, but 10ns Tpd max vs 7ns for the Altera part. 7ns is available in C temp range.

Same TQFP100 package is available. Basically it is 100% compatible second source replacement part in current production.

You can use the MicroChip POF2JED tool to translate the Altera .POF file to the Atmel .JED file to program the part.

I have done this process for EPM7064 devices in the PLCC44 package with no issues.

You will have to go to the MicroChip site to get any further info on the part and the tools.

Correction: part number should be ATF1504AS-10AU100

[Firaseng]

Thank you much

As long as you can buy it, it's not a problem. The work of modifying the code is troublesome, and replacing the chip may not work.

Hello,

As user '_AK6DN_', You need the source code to migrate to any other device to do a recompile. Yes, it will also be the same as for EPM7064STI100-7 CPLD.

Hope that answers your question.

Hello,

It has been a while since you last posted at this community forum. Do you have any further question regarding this case?

Hi Nazrul,

I did finally locate the Verilog code for the FPGA on that project ,so in that case which FPGA may require the least amount of code changes ,Cyclone II or Max V? I am referring to any macros custom to that chip?

Thanks  

[_AK6DN_]

Probably about the same for either target device, but it also depends upon what IP (if any) you have in your original verilog code.

If it is mostly all your user written verilog, with may just PLL or I/O cell references, should be pretty easy to port.

If you used some old IP block that no longer is available you will need to write code to replace it or find the current equivalent, if any.

In any event having that verilog gives you a fighting chance of moving to a new device.
