The Stratix® IV FPGA I/O structure is based on the successful Stratix III FPGA I/O structure with its proven high-performance architecture. For this reason, many of the Stratix III documents referenced in Table 1 are directly applicable to Stratix IV FPGAs. The I/O structure itself is ideal for interfacing to existing and emerging external memory standards. For information about the external memory interface protocols supported by Stratix IV, visit the External Memory Interface Support Center.
Table 1 lists resources and technical collateral for building external memory interfaces on Stratix IV FPGAs.
