The 93415FM is a 1Kx1 cache SRAM built in CMOS, with a 60 ns access time. In a cache or buffer application, it sets the minimum CPU wait-state budget: a processor with a 50 ns memory cycle will need one wait state; a 70 ns cycle can run zero-wait.
Active lifecycle — no last-time-buy risk
For a BOM line, that removes the sourcing urgency that comes with an NRND or obsolete part.
The listed package type is Bulk. That means the parts ship in tubes or trays, not on tape-and-reel. If your line uses a pick-and-place feeder, you will need to transfer them to tape or hand-place them. For prototype runs or low-volume production, Bulk is often the more cost-effective option. For high-volume, check if a tape-and-reel variant exists — the 93415FM does not list one here.
