At this density and access rate, the part fits cache-tag or high-speed lookup-table duty where a synchronous burst SRAM would add unnecessary pipeline latency. ## Supply and packaging Supplied in Bulk packaging — the loose-tube or tray format suits prototype builds and low-volume production runs where reeled tape-and-reel would incur a minimum-order quantity premium. For high-volume pick-and-place, confirm the reel option separately at RFQ.","metaTitle":"R1QDA7218ABB-20IB0 SRAM, 4Mx18, 0.45 ns, Active","metaDescription":"R1QDA7218ABB-20IB0 standard SRAM, 4Mx18 organization, 0.45 ns access time.
