For a system architect sizing a high-throughput cache or FIFO buffer, this part delivers 1.8 GB/s peak bandwidth on an 18-bit-wide data bus (1M x 18 organization). The 1.7V–1.9V supply rail is narrow — it requires a dedicated 1.8V core regulator, not a legacy 3.3V or 2.5V SRAM rail. ## Package and footprint — 165-FBGA (13x15) This is a surface-mount package requiring a reflow profile compatible with 1.7V–1.9V SRAM devices. The BGA pitch and ball layout are specific to the Cypress DDR II+ SRAM family; any replacement candidate must match the footprint exactly to avoid a board respin. The shipping medium is Tray, not Tape & Reel, which affects pick-and-place feeder setup for volume assembly.","metaTitle":"Cypress CY7C11481KV18-400BZXC 18Mbit DDR II+ SRAM, 400 MHz","metaDescription":"Cypress CY7C11481KV18-400BZXC synchronous DDR II+ SRAM, 18Mbit (1M x 18), 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, DDR II+","Memory Size":"18Mbit","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":"CY7C11481","Memory Organization":"1M x 18","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$40.3300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5cc086b607ae2c6490ce08c1726ca16f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C11481KV18-400BZXC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C11481KV18-400BZXC?","answer":"No official replacement order code is listed on the lifecycle record for this part. Any substitute must be validated against the original 165-FBGA (13x15) footprint, 400 MHz DDR II+ timing, and 1.7V–1.9V supply rail.
