The 1.7–1.9 V core supply aligns with 1.8 V nominal logic families common in high-speed SRAM designs. The 165-FBGA (15x17 mm) package carries 165 balls — fine-pitch BGA that demands controlled impedance routing and a multilayer PCB with via-in-pad capability if you are routing all 18 data bits plus address at 267 MHz. ## 267 MHz clock — the throughput decision At 267 MHz the DDR-II interface transfers data on both clock edges, so the effective data rate is 534 MT/s per pin. For a 2M x 18 part that means roughly 9.6 Gbit/s aggregate bandwidth on the data bus. That is the tier you spec when a FIFO depth of 2M words and sustained read-write throughput matters more than density — think packet buffers in a 10 GbE switch or waveform memory in a high-speed AWG. If the board sees an industrial floor or outdoor cabinet, you need the industrial-grade variant in the same family. Infineon lists the CY7C1418BV18-267BZXC as Obsolete. That means the part is no longer manufactured and is not available through the factory channel. If you are qualifying a replacement, look at other 36Mbit DDR-II SRAMs in the 165-ball FBGA footprint with the same 1.8 V supply and 267 MHz speed grade. Pin compatibility across the Cypress/Infineon DDR-II family is common within the same density and package, but verify the ball map against your layout — the datasheet is the final authority. ## BGA rework and handling notes","metaTitle":"CY7C1418BV18-267BZXC 36Mbit DDR-II SRAM, 267 MHz, 165-FBGA","metaDescription":"Infineon CY7C1418BV18-267BZXC 36Mbit synchronous DDR-II SRAM, 267 MHz clock, 2M x 18, 1.7–1.9 V, 0–70°C, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"CY7C1418BV18-267BZXC","Package":"Tray","Technology":"SRAM - Synchronous, DDR II","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Clock Frequency":"267 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1418","Memory Organization":"2M x 18","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (15x17)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e799d34f82f5a386c13c0a860b546e61.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the CY7C1418BV18-267BZXC still available through franchised distribution?","answer":"No — it carries an eol_hot status and is confirmed obsolete. The part is no longer in Infineon's active portfolio. Open-market and broker sourcing is the only path for new quantities; an RFQ will clarify current framing posture and lot-date-code availability."},{"question":"What replaces the CY7C1418BV18-267BZXC?","answer":"No official successor or cross-reference alternate is listed in this ledger. A drop-in replacement would need to match the 2M x 18 organization, 165-LBGA footprint, 1.7–1.9 V supply, and 267 MHz timing — sourcing a pin-compatible equivalent is a requalification exercise. An RFQ will surface whether any franchised alternate carries these specs."},{"question":"Does the 165-LBGA footprint of the 267BZXC match the 200BZXC base board layout?","answer":"Both are 165-LBGA (15x17 mm) with the same 0.8 mm ball pitch, so footprint compatibility at the package level is not the concern. The 267 MHz speed grade is the layout variable — impedance-controlled routing and setup/hold margins at the higher clock rate need verification on the existing board spin before assuming the drop-in is timing-clean."},{"question":"What packaging does the CY7C1418BV18-267BZXC ship in, and is tape-and-reel available?","answer":"Tray is the standard shipment format. Tape-and-reel is not listed as an available option for this part. Tray quantities and any minimum order requirements are confirmed through an RFQ — do not assume reel packaging without a written confirmation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1418BV18-267BZXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1418BV18-267BZXC when reusing this data.
