No last-time-buy window or successor order code appears on the record. ## Supply rail and temperature — fit check That covers controlled indoor environments — central office, data centre, lab equipment — but not outdoor or unventilated enclosures. The package is a 165-ball FBGA, 15 mm x 17 mm body, surface-mount only. The Tray shipping medium is the factory format; for reel quantities the buyer should specify at quote time.","metaTitle":"Infineon CY7C1643KV18-450BZC QDR II+ SRAM, 144Mbit, 450 MHz","metaDescription":"Infineon CY7C1643KV18-450BZC is a 144Mbit synchronous QDR II+ SRAM with 450 MHz clock, 1.7V–1.9V supply, 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, QDR II+","Memory Size":"144Mbit","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":"CY7C1643","Memory Organization":"8M 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":"$333.4200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/83052c810355ede007da9e962500af42.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1643KV18-450BZC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C1643KV18-450BZC?","answer":"No official replacement order code is listed.
