The x18 data width is a deliberate choice for designs that carry a parity or ECC bit per byte without widening the bus to x36 — common in networking line cards and high-end storage controllers where data integrity matters but board area is tight. The 333 MHz clock yields a peak data rate of 667 MT/s per pin pair (double data rate), which keeps up with high-throughput ASICs and FPGAs that run a 166–200 MHz controller clock. Supply range of 1.7V to 1.9V means it runs cleanly off a nominal 1.8V rail; the 200 mV tolerance matters when the regulator has ripple or load transients. Do not assume a direct drop-in without verifying the timing and loading against your controller. ## Package and board-level considerations Supplied in a 165-ball LBGA (13x15 mm body), surface-mount only. The fine-pitch BGA calls for controlled solder-paste volume and X-ray inspection post-reflow. The 1.7V–1.9V core supply needs a dedicated rail with adequate decoupling; place at least one 100 nF capacitor per four balls near the center of the array.","metaTitle":"CY7C1518KV18-333BZXI SRAM, 72Mbit DDR II, 333 MHz","metaDescription":"Cypress CY7C1518KV18-333BZXI 72Mbit DDR II+ SRAM, 333 MHz clock, 4M x 18 organization, 1.7-1.9V supply, -40 to 85°C.","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":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"333 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1518","Memory Organization":"4M x 18","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$152.0700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d38b389ed664587c108b4b4896867bcc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1518KV18-333BZXI/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C1518KV18-333BZXI?","answer":"The lifecycle record lists no official replacement part number from Cypress. The part is Obsolete, so the primary sourcing path is the independent surplus channel. Engineers should evaluate current-generation Cypress (now Infineon) QDR/DDR II+ SRAMs in the same 165-FBGA footprint and density range — but timing, clock speed, and supply voltage must be verified against the original controller interface before committing a board spin."},{"question":"Is CY7C1518KV18-333BZXI compatible with 1.8V systems?","answer":"Yes. The supply voltage range is 1.7V to 1.9V, which directly covers a nominal 1.8V rail. The I/O levels are also 1.8V HSTL-compatible, matching the common 1.8V interface used by many FPGAs and ASICs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1518KV18-333BZXI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1518KV18-333BZXI when reusing this data.
