It provides two independent ports with separate address, data, and control lines, allowing simultaneous read/write access from two bus masters without dead cycles. ## Obsolete — what this means for your BOM This part carries an official obsolete product status. ## 9 ns access time and 67 MHz clock — the bus timing budget In a synchronous dual-port design, this sets the margin for the arbitration logic and the setup/hold window at the receiving master. At a 67 MHz clock (approximately 14.9 ns period), the 9 ns access leaves roughly 5.9 ns for clock-to-output delay and signal flight time — tight enough that trace length matching and proper termination on the parallel bus matter. ## Parallel interface and 100-TQFP footprint The memory interface is parallel — 16 data lines plus address and control per port. The tray shipping medium means the parts are delivered in anti-static trays, not tape-and-reel; this is the factory-original packaging for this package size and is typical for engineering samples and low-volume production. Surface-mount assembly requires standard reflow profiling for a 100-lead QFP.","metaTitle":"Infineon CY7C09289V-9AXC 1Mbit Dual-Port SRAM, 9 ns","metaDescription":"Infineon CY7C09289V-9AXC 1Mbit synchronous dual-port SRAM, 64K x 16, 9 ns access, 67 MHz clock, 3V-3.6V, 100-TQFP.","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 - Dual Port, Synchronous","Access Time":"9 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"67 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C09289","Memory Organization":"64K x 16","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"100-TQFP (14x14)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for the CY7C09289V-9AXC?","answer":"For a BOM requiring this exact part, sourcing relies on available independent-distribution inventory."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C09289V-9AXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C09289V-9AXC when reusing this data.
