With a QDR II+ interface that launches data on both edges, the effective data rate per pin is 900 Mbps. The timing closure margin on a board trace of any real length gets tight — the layout engineer will need controlled-impedance routing, matched-length traces, and a solid reference plane under the FBGA. ## Package reality — 165-ball FBGA rework The part comes in a 165-ball FBGA (13x15 mm body). That is a fine-pitch BGA — not something you hand-solder with an iron. If you are planning a rework cycle, expect to use a hot-air station with a preheat plate and a stencil for fresh balls. That means no last-time-buy clock is ticking, and the part remains factory-supported for new designs. There is no forced migration to a successor; the part is in its production prime.","metaTitle":"Infineon CY7C1143KV18-450BZC 18Mbit QDR II+ SRAM, 450 MHz","metaDescription":"Infineon CY7C1143KV18-450BZC 18Mbit synchronous QDR II+ SRAM, 450 MHz clock, 1Mx18 organization, 165-FBGA, 0-70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"Active","Clock Frequency":"450 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":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$38.0400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/471954f57336720bdbf5b29056ab3029.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1143KV18-450BZC/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1143KV18-450BZC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1143KV18-450BZC when reusing this data.
