Cyclone IV E EP5CE55F23C8N Reference schematic design

Hi there

We don't categorize the design into specific package ordering. You can search for example design for Cyclone IV below:

For pin assignment, there are 2 main references you can check:

1. Pinout file (you can check the IO function per pin):

https://www.intel.com/content/www/us/en/programmable/support/literature/lit-dp.html

2. Pin Connection Guideline (you can check on description of each IO function)

Let me know if you have any question.

Thanks.
