This part is aimed at high-throughput buffer and look-aside applications in networking switches, base-station line cards, and test equipment where the bus turnaround penalty of a common-I/O SRAM would cost a clock cycle. ## Industrial temperature range — field-fit check The 85°C ceiling is the standard industrial limit; if your design must sustain junction temperatures above 95°C, you are outside this part's specified operating range. ## 165-FBGA — layout and rework realities The 165-ball FBGA (13x15 mm body, 1.0 mm ball pitch typical for this class) demands controlled-impedance routing on a multi-layer PCB, X-ray inspection after reflow, and a hot-air rework station with a preheater for any ball replacement. The package is surface-mount only; no socketed or through-hole variant exists. Infineon lists this part as Obsolete. That means the factory last-time-buy window has closed, and new production is not available. The only supply route is surplus inventory held by independent distributors. No factory lead time applies; the stock is what is physically on the shelf.","metaTitle":"Infineon CY7C12631KV18-400BZI QDR II+ SRAM, 36Mbit, 400 MHz","metaDescription":"Infineon CY7C12631KV18-400BZI 36Mbit QDR II+ synchronous SRAM, 400 MHz clock, 1.7V–1.9V, -40°C to 85°C, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II+","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C12631","Memory Organization":"2M x 18","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$63.5600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2b5c17d053fe93049e2d3c6e3ea0a3eb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C12631KV18-400BZI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C12631KV18-400BZI still available for purchase?","answer":"Infineon has marked this part Obsolete, so it is no longer in factory production."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C12631KV18-400BZI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C12631KV18-400BZI when reusing this data.
