It is supplied in a 165-ball FBGA (15x17 mm) package for surface-mount assembly. A 375 MHz clock corresponds to a 2.67 ns cycle time. With QDR II's double-data-rate operation on both read and write ports, the effective data window per pin is under 1.34 ns. The PCB designer must budget for trace-length matching, controlled impedance, and adequate decoupling on the 1.7V–1.9V rail to maintain signal integrity. The 165-FBGA package with its fine ball pitch demands careful fan-out planning — the 15x17 mm footprint does not leave room for oversized vias under the body. Any buyer adding this to a new BOM should qualify an alternate QDR II SRAM from the same or a compatible family.","metaTitle":"Cypress CY7C1565V18-375BZC QDR II SRAM, 72Mbit, 375 MHz","metaDescription":"Cypress CY7C1565V18-375BZC is a 72Mbit QDR II synchronous SRAM with 375 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":"375 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":"What is the replacement for CY7C1565V18-375BZC?","answer":"The QDR II SRAM family from Cypress/Infineon includes multiple density and speed grades, but a pin-compatible direct successor is not confirmed. A cross-reference search against other 2M x 36 QDR II devices in a 165-FBGA package is recommended for dual-sourcing or replacement qualification."},{"question":"What voltage does CY7C1565V18-375BZC require?","answer":"The CY7C1565V18-375BZC operates from a 1.7V to 1.9V core supply. This is a low-voltage rail that must be clean and well-regulated — any ripple or droop at 375 MHz clock rates will directly impact timing margin on the QDR II bus."},{"question":"What is the clock frequency of CY7C1565V18-375BZC?","answer":"The maximum clock frequency is 375 MHz.
