This class of memory is typically used in high-throughput buffer applications — network switches, base stations, and test equipment — where the DDR interface doubles the data rate without increasing the clock frequency. The 400 MHz clock rate is the core performance spec. Because the interface is DDR II+, data is transferred on both rising and falling clock edges, giving an effective data rate of 800 MT/s per pin. With a 36-bit data bus, that translates to a peak bandwidth of 3.2 GB/s. The 1.7 V–1.9 V supply range keeps I/O levels compatible with low-voltage logic families like HSTL or SSTL, but the tight voltage tolerance means the board's power rail needs to be clean and well-regulated — a 1.8 V rail with ±5% regulation is typical. This part is no longer available through the factory as new stock. No official successor part is listed in the record. ## 165-FBGA footprint and assembly The 165-ball FBGA (13x15 mm) is a fine-pitch BGA. The tray shipping medium means the parts arrive in antistatic trays, not tape-and-reel; plan for pick-and-place handling accordingly.","metaTitle":"CY7C1150KV18-400BZXC 18Mbit DDR II+ SRAM, 400 MHz, 165-FBGA","metaDescription":"Infineon CY7C1150KV18-400BZXC 18Mbit synchronous DDR II+ SRAM, 400 MHz clock, 512K x 36 organization, 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":"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/CY7C1150KV18-400BZXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1150KV18-400BZXC obsolete?","answer":"Yes, the CY7C1150KV18-400BZXC carries an Obsolete lifecycle status.

Because the part is obsolete, verify that your design can accept a surplus-sourced component or plan for a redesign with a current-generation SRAM."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1150KV18-400BZXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1150KV18-400BZXC when reusing this data.
