QDR II (Quad Data Rate) architecture delivers two read and two write data words per clock cycle, giving this part a peak bandwidth of 28.8 Gbit/s on a single 1.8 V supply rail. It is built for high-throughput, low-latency lookup and buffering in networking switches, routers, telecom line cards, and test equipment where SRAM speed and deterministic access matter more than DRAM density. At 400 MHz, the QDR II interface transfers data on both rising and falling edges of the clock, so the effective data rate per pin is 800 Mbps. For a 36-bit-wide data bus, that translates to 28.8 Gbps aggregate bandwidth. The 2M x 36 organization means a single chip can hold 2 million 36-bit words — enough for a large forwarding table or a deep packet buffer in a 10/25 GbE line card. Cypress (now Infineon) has discontinued production, and no factory orders or last-time-buy windows remain open. ## 165-FBGA — board-level reality The 165-ball FBGA package measures 15 x 17 mm with a 1.0 mm ball pitch. Surface-mount only, no through-hole option.","metaTitle":"CY7C1565V18-400BZXC 72Mbit QDR II SRAM, 400 MHz, 165-FBGA","metaDescription":"Infineon/Cypress CY7C1565V18-400BZXC 72Mbit synchronous QDR II SRAM, 400 MHz clock, 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":[{"question":"Where can I buy CY7C1565V18-400BZXC?","answer":"No factory stock or last-time-buy window remains."},{"question":"Is CY7C1565V18-400BZXC obsolete?","answer":"Yes, this part is officially obsolete per the manufacturer.
