This part is built for high-throughput buffer applications in networking, telecom line cards, and industrial data acquisition where the bus must sustain full-rate traffic without arbitration stalls. That means Cypress has ended production; no last-time-buy window remains. No factory lead time applies — the part is what it is on the open market. The CY7C1514V18-167BZI comes in a 165-ball FBGA (15x17 mm body), surface-mount only. The 1.0 mm ball pitch is standard for this density class; the footprint requires a 165-LBGA land pattern with via-in-pad or microvia escape routing for the 36-bit data bus on both ports. The 167 MHz clock rate demands careful signal-integrity layout — matched trace lengths on the QDR address and data buses, and solid decoupling on the 1.8 V rail within 5 mm of each supply ball pair.","metaTitle":"Cypress CY7C1514V18-167BZI 72Mbit QDR II SRAM, 167 MHz","metaDescription":"Cypress CY7C1514V18-167BZI 72Mbit QDR II synchronous SRAM, 167 MHz clock, 1.7V-1.9V supply, -40°C to 85°C, 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, QDR II","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"167 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1514","Memory Organization":"2M x 36","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$161.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1e426080ef01f46ce71cd7c92ba1992.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1514V18-167BZI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1514V18-167BZI obsolete?","answer":"Yes, the manufacturer lists this part as Obsolete.

A functionally compatible QDR II SRAM in the same 72 Mbit density and 165-FBGA package would need to match the 167 MHz speed grade and 1.8 V supply — check with your Cypress (now Infineon) field applications team for a recommended drop-in alternate."},{"question":"What is the difference between QDR II and QDR II+?","answer":"QDR II+ extends the clock frequency range beyond QDR II's limit (typically above 250 MHz) and adds on-die termination and output impedance calibration. The CY7C1514V18-167BZI is a QDR II device, not QDR II+ — it operates at 167 MHz without those features."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1514V18-167BZI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1514V18-167BZI when reusing this data.
