from the Cyclone II errata sheet:
The die revision is identified by the alphanumeric character (Z) before the
fab code (first two alphanumeric characters) in the date code printed on the
top side of the device.
A X?Z ## ####
^ Die Revision
my EP2C20F484C8N is labeld with (looks a little bit different :-( ):
K CAA9T0619A
is the die Revision A????
I need this to know, because I use dual clock FIFOs. (Do I need the
workaround of the "M4K block write operations may fail ..."-error in the
Revision A?)
Thanks, Manfred
