Its 278 MHz clock rate means the memory can deliver back-to-back read/write transactions every clock edge — double data rate on both address and data buses — which is exactly what network packet buffers, telecom line cards, and high-end test equipment need to keep pipeline stages fed without wait states. ## Supply rails and temperature — design-in constraints Housed in a 165-LBGA (13×15 mm FBGA), this is a fine-pitch BGA. No socket, no hand-solder field swap — it needs a reflow profile, X-ray inspection, and a board designed for the footprint. Keep the moisture sensitivity level in mind if the tray has been open. This part is officially obsolete per the Cypress/Infineon lifecycle record. There is no listed direct replacement from the manufacturer, so new-production allocations are gone. Sourcing is through independent distribution and surplus channels — last-time-buy stock that has already shipped, or broker inventory. No factory lead time applies.","metaTitle":"CY7C1318BV18-278BZC Cypress DDR II SRAM, 18 Mbit, 278 MHz","metaDescription":"CY7C1318BV18-278BZC Cypress (Infineon) 18 Mbit synchronous DDR II SRAM, 1M×18 organization, 278 MHz clock, 1.7–1.9 V supply, 165-LBGA, 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, DDR II","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"278 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1318","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ca01039c1080f3df0c402ce9f5e47223.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C1318BV18-278BZC obsolete or end-of-life?","answer":"Yes, it is officially obsolete.
