At 300 MHz the QDR II bus delivers a data rate of 600 million transfers per second per port (double-data-rate on the clock edges). The 2M x 36 organization means a 36-bit-wide data word per access, so the peak bandwidth sits around 21.6 Gbit/s. That level of throughput is what a 10 GbE line card or a radar beamformer needs to keep its FIFO from underflowing. If your system runs a slower clock domain, the part also works at lower frequencies — but the 300 MHz rating is the headroom you pay for, and it is the figure that determines whether this SRAM can match the bus timing of a high-end FPGA or ASIC without inserting wait states. Cypress (now Infineon) lists the CY7C1515KV18-300BZI as Active. ## Package and supply — the board-level fit The 165-ball FBGA (13x15 mm) is a surface-mount BGA with a 1.0 mm ball pitch — standard for high-density SRAMs in this density tier. The supply range of 1.7V to 1.9V means it runs from a nominal 1.8V rail, which is the common core voltage for QDR II memories. If your board already carries a 1.8V supply for the FPGA or ASIC bank, this part drops in without an extra regulator.","metaTitle":"Cypress CY7C1515KV18-300BZI 72Mbit QDR II SRAM, 300 MHz","metaDescription":"Cypress CY7C1515KV18-300BZI 72Mbit QDR II synchronous SRAM, 300 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":"Active","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":"Active","Clock Frequency":"300 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 (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$173.0988","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fecc7e54873197095792ce9e146235b1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1515KV18-300BZI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1515KV18-300BZI obsolete or end-of-life?","answer":"No. The lifecycle status is Active, meaning Cypress (Infineon) still manufactures it."},{"question":"Can CY7C1515KV18-300BZI be replaced by a slower speed grade?","answer":"Yes, if your bus timing budget allows a lower clock rate. The QDR II family includes speed grades below 300 MHz — for example, 250 MHz or 200 MHz variants in the same 72 Mbit density and 165-FBGA footprint. Dropping the speed grade reduces cost and may ease signal-integrity closure on the PCB, but you must verify that the slower part still meets your read/write throughput requirement without inserting wait states. The pinout and package are consistent across the speed grades, so a board respin is not needed for the swap."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1515KV18-300BZI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1515KV18-300BZI when reusing this data.
