Is there a pin compatible part replacement for EP1C20F400C8N from cyclone family? What are the steps I should take while replacing an old FPGA with newone?

Hi SMeet,

There is no pin to pin compatible replacement part for EP1C20F400C8N.

You're right. The part is getting obsolate because of declining demand.

Are you looking to replace with 'pick & place holder' or 'similar features device'?

Thank you.

Hi Calvin,

Thanks for response. I am trying to make the least changes to my existing board. I would prefer a pick & place holder over 'similar features device'. Can you suggest?

Do I need to change the RTL design and bit files if I am going for a new FPGA?

Hi SMeet,

MPN: EP1C20F400C8N Package/Case is FBGA-400.

I couldn't find any active part which similar to this Package/Case.

No, You can still use the same RTL design, but the bit files have to change for new FPGA.

Thank you.
