Hello
I’m from Applications Engineering support team for FPGA/CPLD helping you regarding your issue.
1) Regarding you question on the definition of Intel FPGA part number and device code information, you can refer to below doc link (page 12, figure 1-3)
https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-iv/cyiv-51001.pdf
By referring to figure 1-3 and figure 1-2, you can see, the last 3 digit of FPGA part number just specify the temperature and FPGA core performance speedgrade. Hence, it won’t affect the pin location or pin function of the FPGA.
2) Where do download the pinout file for FPGA (EP4CE55F23) and which column to refer in the pinout file? You can refer and download EP4CE55 pinout file from below link

FPGA is using part number as reference for pin indication. In your case, you are planning to use EP4CE55F23A7N. By referring to figure 1-3, FPGA is using part number F23 = 484 pins. That means you needs to refer to column F484 of the pinout file.
3) Lastly as mention above, we no longer support PCB footprint anymore, it is replaced with Cadence Capture CIS schematic symbol in (olb.) format.
Cadence Capture CIS schematic symbol is available through https://www.intel.com/content/www/us/en/programmable/support/support-resources/download/board-layout-test/pcb/pcb-cadence.html
We apologize for the inconvenience and difficulty that you have. We hope that this update will clears up this matter.
