It operates from a 1.7V to 1.9V supply and is housed in a 165-FBGA (15x17 mm) for surface-mount assembly. ## Clock frequency and memory organization — what drives the BOM fit The 333 MHz clock rate on a DDR II interface means the SRAM delivers two data transfers per clock cycle, effectively doubling the bus throughput compared to a single-data-rate device at the same frequency. For a design that already budgets a 1.7V-1.9V core rail and a 165-ball FBGA footprint, this part slots into the memory controller's timing closure without needing a voltage translation or a larger package. The 8M x 18 organization suits 18-bit or 36-bit bus widths (two chips cascaded) commonly found in wide data-path buffers for Ethernet frame processors or FPGA-based acquisition cards. ## Package and temperature — what the commercial grade tells you If the system must survive -40°C startup or 85°C ambient, a different temperature-grade variant in the same family would be needed.","metaTitle":"Infineon CY7C1618KV18-333BZXC 144Mbit DDR II SRAM, 333 MHz","metaDescription":"Infineon CY7C1618KV18-333BZXC is a 144Mbit synchronous DDR II SRAM with 333 MHz clock, 8M x 18 organization, 1.7V-1.9V supply, in 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, DDR II","Memory Size":"144Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Active","Clock Frequency":"333 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1618","Memory Organization":"8M x 18","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$358.8200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4517e25892cb4d4147c4d98e91af925c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to CY7C1618KV18-333BZXC?","answer":"Within the same base product number family (CY7C1618), other density or speed variants share the same 165-FBGA footprint and 1.7V-1.9V supply, but the exact 144Mbit, 333 MHz configuration is this specific order code.
