Product details

Industrial temperature grade and package

Rated for -40°C to 85°C ambient, this part is specified for factory automation, outdoor telecom cabinets, and motor-drive control boards where the enclosure sees thermal cycling. The 32-SOIC (0.445" body width) is a standard footprint for 5V SRAM; it reflows on the same profile as the rest of a mixed-signal board.

Active lifecycle — no LTB pressure

The CY62128BNLL-55SIT carries an Active product status. No last-time-buy window has been announced, and no successor has been designated. For a BOM line that needs a 5V asynchronous SRAM in a 32-SOIC, this part is a current-production choice, not a surplus scavenge.

Frequently asked questions

What is the difference between CY62128BNLL-55SIT and CY62128BNLL-55SXI?

The suffix difference typically indicates a packaging or environmental compliance variant (e.g., lead-free vs. tin-lead finish). Both share the same 1 Mbit density, 55 ns access, and 32-SOIC package. Verify the specific suffix definition against the manufacturer's ordering guide.

What is the replacement or equivalent for CY62128BNLL-55SIT?

No official replacement has been designated. For a functional second-source, the CY7C1018DV33-10VXI is a 1 Mbit asynchronous SRAM with 10 ns access, but note it operates at 3.0V, not 5V. The CY7C109D-10ZXIT is a 5V 1 Mbit part with 10 ns access in a different package. Neither is a drop-in replacement; verify pin compatibility and supply voltage before substituting.
