This part targets high-bandwidth, low-latency buffer applications in networking line cards, telecom switches, and high-end test equipment where the memory must keep pace with a 300 MHz data bus. At 300 MHz, the DDR II interface transfers data on both clock edges, so the effective data rate is 600 MT/s per I/O. That bandwidth is what makes this part a fit for designs that need to stream large packets or samples without stalling the controller. No hand-soldering this one; it is a surface-mount-only part. Cypress (now part of Infineon) no longer manufactures the CY7C1518KV18-300BZI.","metaTitle":"Cypress CY7C1518KV18-300BZI 72Mbit DDR II SRAM, 300 MHz","metaDescription":"Cypress CY7C1518KV18-300BZI 72Mbit synchronous DDR II SRAM, 300 MHz clock, 165-FBGA, -40°C to 85°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":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"300 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":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d38b389ed664587c108b4b4896867bcc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1518KV18-300BZI/alternatives.json"},"ai":{"faq":[{"question":"What is a direct replacement for CY7C1518KV18-300BZI?","answer":"No official replacement order code is recorded in the lifecycle data for this part.
