In a typical networking line-card application, that translates to a peak data rate of 900 million transfers per second on the data bus (double data rate). The 4M x 18 organization gives you 72 Mbit of storage, which is enough for deep packet buffers, look-up tables, or large cache structures in telecom infrastructure equipment. It is not a field-swappable part; you will need a reflow oven and a stencil to mount it.","metaTitle":"CY7C1568KV18-450BZXI SRAM, 72Mbit, 450 MHz, DDR II+","metaDescription":"Cypress CY7C1568KV18-450BZXI 72Mbit synchronous SRAM, 450 MHz clock, 4M x 18 organization, 1.7V-1.9V supply, -40°C to 85°C, 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":"450 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1568","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":"$231.3400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0104d0487a721a78527d257de072e3a0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1568KV18-450BZXI/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C1568KV18-450BZXI?","answer":"For a pin-compatible alternative, you would need to check the CY7C1568 family for other speed or temperature variants that are still active, but no specific successor order code is provided."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1568KV18-450BZXI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1568KV18-450BZXI when reusing this data.
