The 1.7V to 1.9V core supply aligns with low-voltage logic families common in 1.8V-dominated systems. For existing BOM lines or repair stock, the only supply channel is independent distribution, where units are sourced from surplus inventory or last-time-buy overruns. ## 165-ball FBGA — layout and rework considerations Surface-mount assembly requires a controlled reflow profile consistent with JEDEC MSL ratings for BGA packages. The fine-pitch ball array demands careful PCB layout for signal integrity at 400 MHz, including matched trace lengths for the QDR II data and address buses, and adequate decoupling capacitance placed close to the supply balls. ## Commercial temperature range — limits deployment It is not specified for industrial or automotive temperature extremes without additional thermal management.","metaTitle":"CY7C1565V18-400BZC QDR II SRAM, 72 Mbit, 400 MHz, Obsolete","metaDescription":"Cypress CY7C1565V18-400BZC is a 72 Mbit QDR II synchronous SRAM with 400 MHz clock, 2M x 36 organization, 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":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1565","Memory Organization":"2M x 36","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/c282ea8f3288590b277ec0782040cb33.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1565V18-400BZC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1565V18-400BZC when reusing this data.
