It clocks at 400 MHz, delivering back-to-back read/write transactions on every clock edge — the DDR II+ protocol eliminates dead cycles on the bus, so the controller sees full-rate throughput without wait states. This part targets high-bandwidth, latency-sensitive buffers: network switch lookup tables, telecom line-card packet memories, and high-end FPGA co-processing where a wide 36-bit word matches internal data-path widths. ## 400 MHz clock — the bus timing reality At 400 MHz the DDR II+ interface toggles data on both edges, so the effective data rate is 800 MT/s per pin. For a 36-bit-wide bus that's 3.2 GB/s peak. The 165-ball FBGA (13x15 mm) keeps signal lengths short, but the layout engineer needs to match trace lengths within a few hundred mils and keep the clock-to-strobe skew tight. That's a ±5.6% window — tighter than a typical 1.8 V ±10% LDO. If the rail droops below 1.7 V during a burst read, the SRAM may lose data or corrupt the bus. Pick a regulator with at least 1% initial accuracy and good transient response; a 1.8 V fixed-output LDO with 300 mV dropout at the load current works. Don't pull this rail from a shared 1.8 V supply that also feeds noisy digital logic — the SRAM's supply needs its own local decoupling. For BOM planning, this part presents no single-source risk; Infineon continues to manufacture it.","metaTitle":"Infineon CY7C1150KV18-400BZC 18Mbit DDR II+ SRAM, 400 MHz","metaDescription":"Infineon CY7C1150KV18-400BZC is a 18Mbit synchronous SRAM with DDR II+ interface, 400 MHz clock, 512K x 36 organization, 1.7V–1.9V supply, 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":"-","Packaging":"Tray","Technology":"SRAM - Synchronous, DDR II+","Memory Size":"18Mbit","Memory Type":"Volatile","Part Status":"Obsolete","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1150","Memory Organization":"512K x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$33.7600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e7a8b5c687236246f4aeedc2d3bd596a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1150KV18-400BZC/alternatives.json"},"ai":{"faq":[{"question":"CY7C1150KV18-400BZC vs CY7C1151KV18: what's the difference?","answer":"Both are 18 Mbit DDR II+ SRAMs in the same 165-FBGA package and supply range.
