Infineon lists the CY7C1021BNV33L-15BAIT as Obsolete. Confirm the exact ball map and supply voltage range before committing a replacement. ## Industrial temperature grade and 3V–3.6V rail The 3V to 3.6V supply is a narrow window — a 2.5V or 5V-only board will need a regulator or a different memory variant. The 15 ns access time is the cycle-limiting spec for bus timing; a slower processor or a wait-state insertion may tolerate a 20 ns part, but a 10 ns part would be overkill unless the bus is already marginal. ## 48-FBGA footprint — layout and rework notes The 48-FBGA (7x7) package has a 0.75 mm ball pitch typical for this density. If you are reworking a board that originally used this part, the moisture sensitivity level (MSL) should be confirmed from the date-code trace — FBGA packages often require a bake cycle before reflow if exposed to ambient humidity. The Tape & Reel delivery is standard for pick-and-place; no tube or tray option is listed.","metaTitle":"CY7C1021BNV33L-15BAIT SRAM 1Mbit 15ns 48-FBGA Obsolete","metaDescription":"Infineon CY7C1021BNV33L-15BAIT asynchronous SRAM, 64K x 16, 15 ns access, 3V-3.6V, -40°C to 85°C, 48-FBGA.
