The QDR II+ architecture eliminates the read-write turnaround dead cycles that older synchronous SRAMs suffer, so back-to-back transactions at full clock rate are possible. For a system architect sizing the memory subsystem, the 400 MHz rating is the ceiling for the bus timing closure — the controller and PCB trace delays must fit within one clock period at that speed. Layout engineers should budget for at least four decoupling capacitors per supply ball group, placed as close to the BGA footprint as the escape routing allows.","metaTitle":"CY7C1645KV18-400BZXI QDR II+ SRAM, 144Mbit, 400 MHz","metaDescription":"Infineon CY7C1645KV18-400BZXI 144Mbit QDR II+ synchronous SRAM, 400 MHz clock, 1.7V-1.9V supply, -40°C to 85°C, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"Active","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1645","Memory Organization":"4M x 36","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$319.9600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/83052c810355ede007da9e962500af42.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1645KV18-400BZXI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1645KV18-400BZXI when reusing this data.
