No industrial or automotive exposure — the part will not hold timing below freezing or above a warm cabinet.
Housed in a 256-ball FBGA, the footprint is fine-pitch BGA. Board routing needs via-in-pad or microvias for the inner balls. Rework requires a pre-heated profile; hand-soldering is not practical. The bulk packaging means trays, not tape-and-reel — plan for pick-and-place nozzle change if your line is set for reels.
The CY7C2264XV18-366BZXC is a 36 Mbit synchronous SRAM with a 366 MHz clock and 1.7 V supply — it is not a pin-compatible drop-in. The CYD01S18V-167BBC shares the 167 MHz clock and 4 ns access but is only 1 Mbit (64K x 18). Neither is a direct second-source; verify footprint and supply rail before substituting.
