15 years ago --- Quote Start --- I looked it up. A18 on a 512x16 part is the same as CE2 on the existing part. You should be able to drop in a 512x16 with no board modifications - but use the pin assigned to CE2 in the manual as A18 instead. I was looking at this part: http://www.issi.com/pdf/61-64wv51216.pdf but I believe that is part of the JEDEC spec. --- Quote End --- Hi,jshamlet. Thank you for your help! But,I didn't find any information in the manual,which pin be used assigned to A18 from the FPGA chip. pds123
