Hello, I installed Quartus 19.1. I have Cyclone IV EP4CE6E22C8N but I can't find it in Quartus 19.1 list of devices. Are EP4CE6E22C8N and EP4CE6E22C8 the same ?

Hi Artem Ulyashev You can refer to the following handbook, Chapter 1, section Reference and Ordering Information, Figure 1-3: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-iv/cyclone4-handbook.pdf where "N" at the end is the Optional Suffix indicating Lead-free packaging. Thanks. Regards Eng Wei
