That matters for high-throughput pipelines like network packet buffers, DSP coefficient stores, or test-equipment waveform memories where the bus must stay full every cycle. ## Package and layout — 165-ball FBGA This part carries a Last Buy status. That means Infineon has stopped taking blanket orders and is running a final procurement window — once that closes, the only channel is surplus or broker stock. If you have a production run that needs this exact density and speed grade, the decision is whether to buy lifetime buy quantities now or qualify a replacement.","metaTitle":"Infineon CY7C1143KV18-400BZI QDR II+ SRAM, 18Mbit, 400 MHz","metaDescription":"Infineon CY7C1143KV18-400BZI 18Mbit QDR II+ synchronous SRAM, 400 MHz clock, 1.7-1.9V, -40 to 85°C, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II+","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Last Time Buy","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1143","Memory Organization":"1M 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":"$34.7440","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/471954f57336720bdbf5b29056ab3029.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1143KV18-400BZI/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1143KV18-400BZI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1143KV18-400BZI when reusing this data.
