Headline speed and memory map
The R1QDA7218ABB-20IB0 is a standard SRAM organized 4Mx18 with a 0.45 ns access time — the speed grade governs the read-cycle window for the memory controller, not the core clock. 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.
