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.","metaTitle":"Infineon CY62128BNLL-55SIT MoBL SRAM, 1 Mbit, 55 ns, 32-SOIC","metaDescription":"Infineon CY62128BNLL-55SIT MoBL asynchronous SRAM, 1 Mbit (128K x 8), 55 ns access, 4.5V-5.5V, -40°C to 85°C, 32-SOIC.

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."},{"question":"What is the replacement or equivalent for CY62128BNLL-55SIT?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY62128BNLL-55SIT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY62128BNLL-55SIT when reusing this data.
