This is a high-bandwidth, low-voltage memory intended for networking, telecom, and high-performance compute applications where fast, back-to-back read/write throughput is critical. ## 375 MHz clock — what it buys the system architect The 375 MHz clock rate on a DDR II interface means data is transferred on both clock edges, effectively doubling the data rate per pin. For a 36-bit-wide bus, this yields a peak bandwidth of 27 Gbit/s (3.375 GB/s). That kind of throughput suits high-port-count switches, packet buffers, and real-time processing pipelines where the memory bus is the bottleneck. ## 165-ball FBGA — rework and layout notes The 165-FBGA (15x17 mm) is a fine-pitch BGA. This is not a hand-rework-friendly package without a rework station and stencil. The board needs via-in-pad or microvia escape routing for the inner balls. Thermal management is via the BGA's central ground plane — no exposed pad, so the PCB copper plane and via array under the package do the heat spreading. ## Lifecycle: obsolete — sourcing reality The CY7C1270V18-375BZI is marked obsolete by Infineon. If a design is still in development, a migration to a current-generation synchronous SRAM or RLDRAM family should be evaluated.","metaTitle":"CY7C1270V18-375BZI Infineon DDR II SRAM, 36Mbit, 375 MHz","metaDescription":"Infineon CY7C1270V18-375BZI synchronous DDR II SRAM, 36Mbit (1M x 36), 375 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":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, DDR II","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"375 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1270","Memory Organization":"1M x 36","Operating Temperature":"-40°C ~ 85°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/7016544070d3ffa3450211dd72b6e240.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy CY7C1270V18-375BZI?","answer":"The CY7C1270V18-375BZI is obsolete and no longer in production."},{"question":"Is CY7C1270V18-375BZI obsolete?","answer":"Yes, Infineon lists the CY7C1270V18-375BZI as obsolete.
