The 48-SSOP package (0.295\" body width, 7.50 mm) is a fine-pitch SSOP — reworkable with hot air if the pad layout has adequate solder mask dams between pins. The Tape & Reel variant (TR suffix) is the standard for automated pick-and-place; the Cut Tape option suits prototype or low-volume builds. ## Active lifecycle — no near-term end-of-life concern Cypress lists this part as Active with ROHS3 compliance. The parallel NVSRAM family has been stable for years; no successor has been announced.","metaTitle":"Cypress CY14B256LA-SP45XIT NVSRAM, 256Kbit, 45 ns, Parallel","metaDescription":"Cypress CY14B256LA-SP45XIT 256Kbit NVSRAM with 45 ns access time, parallel interface, 2.7V-3.6V supply, -40°C to 85°C, 48-SSOP.

The silicon, speed grade, temperature range, and package body are identical. Choose the XIT variant for automated assembly lines that feed from reels."},{"question":"When sourcing CY14B256LA-SP45XIT, what's the closest functional second-source?","answer":"There is no pin-compatible second-source NVSRAM from another manufacturer at the same density and access time. The CY7C1399BN-12VXIT is a 256Kbit SRAM (volatile) in a similar package, but it loses data on power loss — it is not a functional replacement for the NVSRAM's non-volatile feature. For a non-volatile alternative, consider a serial EEPROM or FRAM, but those require a different interface and software changes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY14B256LA-SP45XIT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY14B256LA-SP45XIT when reusing this data.
