This is a volatile, fast static RAM for designs that need deterministic read/write latency without refresh cycles — the kind of memory you pick for cache, packet buffers, or real-time control stores where DRAM's refresh overhead is unwelcome. That is the same speed grade as the earlier CY7C1061AV33 family, so a drop-in swap on an existing layout is plausible — same 54-TSOP II footprint, same supply range.
The 54-TSOP II package (0.400" body width, 10.16 mm) is a standard asynchronous SRAM footprint shared across multiple vendors.
No LTB window to chase, no last-time-buy risk for a production program starting now. The Tape & Reel suffix (ZSXIT) indicates this variant ships on 13-inch reels for automated pick-and-place. If your line runs tube or tray, the base part number CY7C1061GN30-10ZSXI is the tray version — same silicon, same speed grade, different shipping medium.
