The last-time-buy window has passed, so new stock is only available through independent distribution or surplus channels. If you are qualifying a replacement, the official successor is not listed in the record — expect to evaluate a pin-compatible NoBL™ SRAM or a different density/speed grade.
NoBL™ eliminates the dead bus cycle between read and write turns, so back-to-back transactions run at full 167 MHz clock rate without wait states. The 3.4 ns access time from clock edge to data valid gives the system architect timing margin for a 167 MHz bus with moderate trace lengths.
2.5 V supply, industrial temperature — board-level fit
