FAQ
Q: Why do industrial designs still use SDRAM?
A: Many long-lifecycle controllers and FPGAs support SDRAM directly; it avoids redesign risk in proven platforms.
Q: What do the speed grade suffixes mean?
A: They indicate the maximum clock grade; the -6 grade runs up to 166 MHz.
Q: Is long-term supply available?
A: ISSI specializes in long-lifecycle products — contact us for availability planning.
