The 250 MHz clock rate delivers back-to-back read/write transactions without dead cycles — critical for high-throughput networking or telecom line cards where bus turnaround latency directly impacts packet processing throughput. ## Supply and temperature envelope Packaged in a 165-ball FBGA (13x15 mm) with a parallel memory interface. The 0.80 mm ball pitch requires careful PCB fan-out; a four-layer board with a dedicated VDDQ plane is typical to keep supply noise within the 1.7 V – 1.9 V window. Infineon lists the CY7C1911KV18-250BZCT as Obsolete. No official successor or pin-compatible drop-in replacement is cited in the lifecycle record. For existing BOM lines, the only sourcing path is through independent or franchise-distributor inventory — last-time buy windows have closed.","metaTitle":"CY7C1911KV18-250BZCT QDR II SRAM 18 Mbit 250 MHz Obsolete","metaDescription":"Infineon CY7C1911KV18-250BZCT QDR II synchronous SRAM, 18 Mbit (2M x 9), 250 MHz, 1.7-1.9 V, 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":"Tape & Reel (TR)","Technology":"SRAM - Synchronous, QDR II","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"250 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1911","Memory Organization":"2M x 9","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/66c682634920522619c3dfcc3a818445.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1911KV18-250BZCT?","answer":"No official pin-compatible replacement is cited in the lifecycle record.
