That throughput is what makes this part a fit for high-port-count switches and routers where the SRAM must keep up with the line rate without stalling the pipeline. The 2M x 36 organization also aligns naturally with 36-bit-wide data buses common in network processors and FPGAs, avoiding the need for multiple narrower memories. ## 165-ball FBGA — layout and assembly notes The part comes in a 165-ball LBGA (15x17 mm FBGA footprint). That is a fine-pitch BGA — not a hand-solderable package. The board needs a controlled reflow profile, X-ray inspection for voiding, and careful decoupling placement close to the supply balls. The 1.7V to 1.9V core supply is tight; a local LDO or low-noise regulator per the datasheet's recommended decoupling scheme keeps the SRAM's internal PLL clean.","metaTitle":"Cypress CY7C1515V18-167BZXI 72Mbit QDR II SRAM, 167 MHz","metaDescription":"Cypress CY7C1515V18-167BZXI 72Mbit QDR II synchronous SRAM, 167 MHz clock, 2M x 36 organization, industrial temp -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":"CY7C1515","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":"$133.3300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7f8619780a71831bb313ad759dcea688.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1515V18-167BZXI/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy CY7C1515V18-167BZXI available via RFQ confirmation?","answer":"This obsolete SRAM is sourced through independent distribution.
