The headline timing parameter is the 0.45 ns access time. That figure — 450 picoseconds — places this part in the fast-SRAM class, where cycle time tracks access time closely. For a controller expecting a 250 MHz read rate, the 0.45 ns window means the address-to-data valid path must be clean; any board-level skew or crosstalk on the data bus eats directly into hold margin. This is a synchronous or asynchronous standard SRAM depending on the controller interface — the 0.45 ns figure is the address-access time, not the clock-to-output delay. The part ships in bulk (tray or tube), not tape-and-reel, so it is suited for prototype builds or low-volume production where reel packaging is not required. ## Active lifecycle — no obsolescence watch needed Renesas lists the R1QEA7218ABG-22IB0 as Active. For a BOM line that requires this density and speed grade, the part is a stable selection — no forced redesign horizon from the manufacturer side. Sourced through independent distribution channels.","metaTitle":"Renesas R1QEA7218ABG-22IB0 SRAM, 4Mx18, 0.45 ns","metaDescription":"Renesas R1QEA7218ABG-22IB0 standard SRAM, 4Mx18 organization, 0.45 ns access time.
