The 250 MHz clock rate means the memory delivers a new data word on each rising and falling edge — DDR II architecture — effectively doubling the throughput per pin compared to a single-data-rate part at the same frequency. The 36-bit-wide data bus suits systems that move 36-bit words or can tolerate a few spare lanes for ECC or sideband signaling. ## Last Buy — what it means for the BOM line This is the final procurement window from the manufacturer — once the last-time-buy order period closes, the part will not be produced again. For an existing design that already qualifies this footprint and timing, the immediate decision is whether to secure lifetime buy quantities or begin evaluating a replacement. ## Package and board-fit — 165-ball FBGA The part comes in a 165-ball FBGA (15 mm x 17 mm body), surface-mount only. The package is moisture-sensitive; the tray shipping format means the parts arrive in the anti-static matrix, not on tape, so plan for manual or tray-fed pick-and-place. Commercial temperature range (0°C to 70°C) limits the part to indoor, controlled environments — no extended-temp or industrial qualification. If the system sees an unheated enclosure or an automotive bay, this grade will not hold the timing at the cold or hot end. ## Supply rails and decoupling The core supply range is 1.7 V to 1.9 V — a 1.8 V nominal rail with ±0.1 V tolerance covers it. The DDR II interface uses HSTL or similar referenced logic levels; the VREF and VDDQ rails need their own decoupling plan, separate from the core. A 100 nF per supply pin, placed within 2 mm of the ball, is the starting point for the bypass network.","metaTitle":"Infineon CY7C1620KV18-250BZXC 144Mbit DDR II SRAM, 250 MHz","metaDescription":"Infineon CY7C1620KV18-250BZXC 144Mbit DDR II+ SRAM, 250 MHz clock, 4M x 36 organization, 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, DDR II","Memory Size":"144Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Last Time Buy","Clock Frequency":"250 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1620","Memory Organization":"4M x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$227.4777","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4517e25892cb4d4147c4d98e91af925c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the CY7C1620KV18-250BZXC and get a price?","answer":"No stock-holding claim is made here."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1620KV18-250BZXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1620KV18-250BZXC when reusing this data.
