The 400 MHz clock rate delivers four words per clock cycle — two reads and two writes — giving the memory bus the bandwidth to keep a 36-bit datapath fed without dead cycles between read and write turns. That bus-turnaround elimination is the reason QDR II+ parts show up in network packet buffers, search engines, and high-speed telecom line cards where back-to-back transactions are the norm, not the exception. The 1.7V to 1.9V supply rail aligns with the core voltage of many modern FPGAs and network processors, letting the SRAM share a common power plane without an extra regulator. That 1.7V minimum is worth noting for cold-crank or brownout scenarios — the part stays operational down to that floor, not just at the nominal 1.8V. ## 165-ball FBGA — layout and handling Housed in a 165-ball FBGA measuring 13x15 mm, the footprint is a standard high-density SRAM ballout. For a new design or a production BOM line, there is no forced obsolescence risk here — the part should remain orderable for the foreseeable future.","metaTitle":"Infineon CY7C1145KV18-400BZXI QDR II+ SRAM, 18Mbit, 400 MHz","metaDescription":"Infineon CY7C1145KV18-400BZXI synchronous QDR II+ SRAM, 18Mbit (512K x 36), 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":"18Mbit","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":"CY7C1145","Memory Organization":"512K x 36","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$44.9925","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/471954f57336720bdbf5b29056ab3029.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1145KV18-400BZXI/alternatives.json"},"ai":{"faq":[{"question":"What is the clock frequency of CY7C1145KV18?","answer":"The clock frequency is 400 MHz, which with QDR II+ operation delivers four data transfers per clock cycle for high-bandwidth read/write throughput."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1145KV18-400BZXI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1145KV18-400BZXI when reusing this data.
