This is a volatile SRAM, so data is lost when power is removed — it's built for high-throughput buffering, not storage. At 250 MHz, the DDR II interface transfers data on both clock edges, giving an effective 500 MT/s data rate per pin. That's the kind of bandwidth you need in a network processor lookaside buffer or a high-speed telecom line card where every nanosecond of latency matters. The 72 Mbit density (4M x 18) provides enough depth for large packet queues or lookup tables without spilling to slower DRAM. ## 165-FBGA package — layout and rework realities Hand-soldering is impractical — this is a rework-station job with a hot-air nozzle and a stencil. The Tray shipping medium means it arrives in a JEDEC tray, not tape-and-reel, so factor that into your pick-and-place setup. ## Obsolete — sourcing this part today That means Cypress no longer manufactures it, and no factory orders are accepted.","metaTitle":"Cypress CY7C1518KV18-250BZXC 72Mbit DDR II SRAM, 250 MHz","metaDescription":"Cypress CY7C1518KV18-250BZXC 72Mbit synchronous DDR II SRAM, 250 MHz clock, 4M x 18 organization, 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, DDR II","Memory Size":"72Mbit","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":"CY7C1518","Memory Organization":"4M 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":"$150.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d38b389ed664587c108b4b4896867bcc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1518KV18-250BZXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1518KV18-250BZXC obsolete and what is a direct replacement?","answer":"Yes, Cypress lists this part as Obsolete.
