That clock rate delivers a peak bandwidth of 2.4 GB/s on a single 36-bit port (double-data-rate on both read and write ports). This part is built for the memory wall in high-end networking packet buffers, telecom line cards, and test equipment where back-to-back transactions with zero dead cycles are non-negotiable. The QDR II architecture eliminates bus-turnaround cycles by dedicating separate read and write ports, so a 300 MHz clock translates directly into sustained throughput — no arbitration overhead. That means new designs should not target this device; for existing BOM lines, the only channel is independent distribution — surplus stock, excess inventory, or broker-sourced units. If you are qualifying a replacement, look for a QDR II+ or QDR IV SRAM in the same 165-FBGA footprint and 1.7V–1.9V supply rail — but verify pin compatibility against the original layout; the QDR family has evolved its pinout across generations. ## 1.7V–1.9V supply and industrial temperature range The supply range of 1.7V to 1.9V places this in the low-voltage QDR II generation, compatible with 1.8V nominal core logic. The 165-FBGA package (13x15 mm) is a fine-pitch BGA; layout needs controlled-impedance traces for the 300 MHz clock and data lines, plus adequate decoupling capacitance distributed across the ball field. No thermal pad is exposed on this package — dissipation is through the solder balls and PCB copper.","metaTitle":"Infineon CY7C1415KV18-300BZI QDR II SRAM, 36Mbit, 300 MHz","metaDescription":"Infineon CY7C1415KV18-300BZI 36Mbit synchronous QDR II SRAM, 300 MHz clock, 1M x 36 parallel, 165-FBGA, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"CY7C1415KV18-300BZI","Package":"Tray","Technology":"SRAM - Synchronous, QDR II","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Clock Frequency":"300 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1415","Memory Organization":"1M x 36","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"165-FBGA (13x15)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$88.5500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/476192c054907d86406ed1882873eda6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1415KV18-300BZI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1415KV18-300BZI obsolete?","answer":"Yes, the CY7C1415KV18-300BZI is listed as Obsolete.

The CY7C1415KV18-300BZI runs at 300 MHz, which would not be possible in first-generation QDR. QDR II also operates at a lower supply voltage (1.7V–1.9V versus 2.5V or 3.3V for original QDR), reducing power consumption in high-throughput designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1415KV18-300BZI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1415KV18-300BZI when reusing this data.
