At this speed, the QDR II architecture eliminates the bus-turnaround dead cycles typical of traditional SRAMs, sustaining full-rate reads and writes on alternating edges. The 2M x 9 organization (18 Mbit total) provides a 9-bit-wide data path, which suits designs that need a narrow, high-speed buffer — for example, a 9-bit-wide FIFO or a tag RAM in a cache controller. The 1.7V to 1.9V supply range is tight; the board's power rail must be regulated to within that window, and decoupling at the BGA balls should follow the layout guidelines for QDR II devices to maintain signal integrity at 250 MHz. ## 165-FBGA package — layout considerations The 165-ball FBGA (13x15 mm) is a fine-pitch BGA. Surface-mount assembly requires controlled solder-paste volume and X-ray inspection for voiding and shorts.","metaTitle":"CY7C1911KV18-250BZC QDR II SRAM, 18 Mbit, 250 MHz, Obsolete","metaDescription":"Cypress CY7C1911KV18-250BZC is a 18 Mbit QDR II synchronous SRAM in 165-FBGA, 250 MHz clock, 1.7V–1.9V supply, 0°C–70°C.","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":"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":"$25.4300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/66c682634920522619c3dfcc3a818445.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C1911KV18-250BZC obsolete?","answer":"Yes, the CY7C1911KV18-250BZC is listed as Obsolete.
