How to use quartus to program 5M570ZT100A5NAC

Hi,

refer to decoding of device ordering code in MAX V Overview document. Optional suffix starting with "N" (lead-free) does usually not matter for code generation and programming. Altera can tell if it's different in this case.

Regards Frank

P.S. see also, suggests AC might refer to preprogrammed devices
