External Memory Interface Resources for Stratix Series FPGAs
In addition to on-chip TriMatrix memory structures, Stratix® series FPGAs feature I/O structures designed to allow the direct connection of high-performance external memories. Over time, Stratix series FPGAs have progressed from DDR SDRAM operating at 400 Mbps to DDR3 SDRAM operating at 1600 Mbps. A full listing and comparison of the supported memory interface types for all Intel® high-end FPGAs is available on Intel's External Memory Solutions Center.
Table 1 lists all the relevant resources and downloads needed to assist in the interfacing of Stratix series FPGAs to external memory devices.
