This part is designed for high-bandwidth, low-latency applications such as network packet buffers, telecom line cards, and test equipment where the QDR II architecture eliminates bus-turnaround dead cycles. The 300 MHz clock rate delivers a peak data rate of 1.2 Gbps per I/O pin (DDR on both read and write ports). For a 36-bit-wide data bus, that translates to over 43 Gbps aggregate bandwidth — enough to keep a 10/40 GbE lookup engine fed without stalling. The QDR II architecture uses separate read and write ports, so the bus never needs turnaround cycles, which is critical for back-to-back throughput in content-addressable or flow-table applications. Designers should budget for controlled-impedance routing and per-pin termination on the 165-FBGA footprint to maintain signal integrity at this speed. ## Obsolete — the sourcing reality There is no listed L* successor in the available records, meaning no direct drop-in replacement is on offer from the original vendor. For production lines that still require this exact density and speed grade, procurement must go through independent distribution.","metaTitle":"CY7C1515JV18-300BZC QDR II SRAM, 72 Mbit, 300 MHz, Obsolete","metaDescription":"Cypress/Infineon CY7C1515JV18-300BZC 72 Mbit synchronous QDR II SRAM, 300 MHz, 2M x 36, 1.7-1.9 V, 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":"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":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/09038809a63c942b166e1a3826ed066e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy CY7C1515JV18-300BZC?","answer":"CY7C1515JV18-300BZC is obsolete from the manufacturer, but we source it through independent distribution.
