This part targets high-bandwidth data-path applications: network packet buffers, switch fabric queues, and telecom line-card look-up tables where the memory interface is the throughput bottleneck. ## Supply and temperature — indoor-only envelope That limits the part to controlled indoor environments — telecom central offices, data-centre line cards, and benchtop test equipment. ## Package — 165-ball FBGA, 13x15 mm Supplied in a 165-ball FBGA with a 13x15 mm body. Surface-mount only. ## Last-time-buy — procurement window is closing Infineon has placed this part into Last Buy status. That means the manufacturer has announced a final order window; after that date the part will no longer be produced. For a BOM that depends on this exact density and speed grade, the procurement decision is time-sensitive — order the lifetime buy quantity before the LTB deadline expires. After that, supply shifts entirely to the surplus and broker channel, where pricing and availability are unpredictable.","metaTitle":"Infineon CY7C1165KV18-550BZXC QDR II+ SRAM, 550 MHz, 18 Mbit","metaDescription":"Infineon CY7C1165KV18-550BZXC 18 Mbit QDR II+ synchronous SRAM, 550 MHz clock, 512K x 36, 1.7V–1.9V, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II+","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Last Time Buy","Clock Frequency":"550 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1165","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":"$51.7588","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5666c81a925ed0bb3e38e92f8b809a1d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1165KV18-550BZXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1165KV18-550BZXC obsolete or last time buy?","answer":"Yes, Infineon lists this part in Last Buy status.
