It clocks at 250 MHz, delivering two data words per clock cycle on both read and write ports — effectively four data transfers per clock. That bus architecture eliminates the dead cycles of traditional SRAM when switching between read and write, making it a fit for high-throughput packet buffers in networking gear, telecom line cards, and test equipment where back-to-back transactions matter. ## Supply and temperature — staying inside the operating window If your system sees extended temperature extremes, you will need an industrial-rated QDR II part from a different density or family. Housed in a 165-ball FBGA (15x17 mm body), surface-mount only. The ball pitch and layout are specific to this QDR II generation.","metaTitle":"CY7C1426AV18-250BZXC QDR II SRAM, 36Mbit, 250 MHz, 165-FBGA","metaDescription":"Cypress CY7C1426AV18-250BZXC is a 36Mbit QDR II synchronous SRAM with 250 MHz clock.","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":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"250 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1426","Memory Organization":"4M x 9","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/24fe006d6404e9087adee005b719f789.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1426AV18-250BZXC?","answer":"For new designs, evaluate current-generation QDR II+ or QDR-IV parts from Cypress (Infineon) in the same 165-FBGA package, but confirm ball-map compatibility against the datasheet."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1426AV18-250BZXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1426AV18-250BZXC when reusing this data.
