Last Buy — secure inventory before the window closes
That means the manufacturer has announced end-of-life and is accepting final orders for a limited period. Once that window closes, the only channel will be surplus and broker inventory. If this SRAM is qualified on an active BOM, now is the time to commit the lifetime buy quantity or identify a drop-in replacement before the supply dries up.
128K x 8 organization — byte-wide bus fit
The 128K x 8 organization maps directly to an 8-bit data bus without needing byte-lane steering logic. The 10 ns write cycle time matches the read access time, so back-to-back read-write sequences run at full bus speed. The 32-SOJ package (0.400" body width, 10.16 mm) is a standard JEDEC outline shared by many 128K x 8 asynchronous SRAMs, simplifying board layout reuse.
Industrial temperature grade — what it means for deployment
The 5 V supply rail ties it to legacy 5 V logic families (HCT, ACT, 5 V CPLDs) rather than 3.3 V or 1.8 V cores. If your design has already migrated to a lower-voltage memory bus, a 3.3 V variant like the CY7C1018DV33-10VXI would be the closer fit — same 128K x 8 organization and 10 ns speed, but at 3.0 V nominal.
