It clocks at 250 MHz on a parallel bus, delivering back-to-back read/write throughput without dead cycles — the DDR II means data transfers on both clock edges, effectively doubling the data rate per pin. The 1.7V to 1.9V supply rail places it in the low-voltage SRAM generation, sized for networking packet buffers, switch fabric queues, and high-speed cache where the combination of density and bandwidth matters more than raw density alone. ## Commercial temperature grade — indoor equipment only It is not specified for outdoor base stations, automotive cabin, or factory-floor enclosures where the ambient swings below freezing or above 70°C. The 165-FBGA (15x17 mm) package demands a multi-layer PCB with via-in-pad or microvia fanout under the ball array. ## Obsolete — no factory orders, spot-market only Cypress has marked this part obsolete. No new factory orders, no last-time-buy window remains open. The only channel is independent distribution — surplus inventory, pulled trays, and broker-held stock. Date codes will vary, and counterfeiting risk goes up on a high-value, end-of-life SRAM like this. Every unit we quote is visually inspected and electrically sampled before shipment; we do not drop-ship unverified stock. ## No official successor on record The Cypress SRAM portfolio has moved to newer process nodes and package options, but the ledger carries no direct pin-compatible successor for this exact 165-FBGA footprint. If the board layout is fixed, the only path is the spot market. For a new design, a current-generation DDR II+ or QDR SRAM in a compatible BGA pitch would be the starting point — but that means a board spin.","metaTitle":"Cypress CY7C1418AV18-250BZC SRAM, 36Mbit DDR II, 250 MHz","metaDescription":"Cypress CY7C1418AV18-250BZC 36Mbit synchronous DDR II SRAM, 250 MHz clock, 2M x 18 organization, 165-FBGA, 0°C to 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":"36Mbit","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":"CY7C1418","Memory Organization":"2M x 18","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$61.7800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/873e0dcf19c671dc3abedc70c3688977.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1418AV18-250BZC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C1418AV18-250BZC?","answer":"No direct pin-compatible replacement is listed on the Cypress product line for this 165-FBGA footprint.
