QDR II architecture provides separate read and write data ports, eliminating bus-turnaround dead cycles and sustaining back-to-back throughput at the full clock rate. The 165-ball FBGA package (13x15 mm body) requires careful PCB layout for signal integrity at 300 MHz, including matched trace lengths and adequate decoupling on the 1.8 V rail. ## 300 MHz clock — timing margin and signal-integrity budget At 300 MHz the clock period is roughly 3.3 ns. The QDR II interface uses source-synchronous clocking with a separate read clock and write clock, so the timing budget is shared between the SRAM output hold and the FPGA or ASIC input setup. Board-level simulation should verify that the flight time and crosstalk on the 18-bit data bus stay within the datasheet's tCO and tOH specs.","metaTitle":"CY7C1312KV18-300BZXCT QDR II SRAM, 18 Mbit, 300 MHz","metaDescription":"Cypress CY7C1312KV18-300BZXCT 18 Mbit synchronous QDR II SRAM, 300 MHz clock, 1M x 18 organization, 1.7–1.9 V supply, 0–70 °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":"Tape & Reel (TR)","Technology":"SRAM - Synchronous, QDR II","Memory Size":"18Mbit","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":"CY7C1312","Memory Organization":"1M x 18","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$37.4675","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dea3bcace4592b08079c9a8b90f16dd7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1312KV18-300BZXCT/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to CY7C1312KV18-300BZXCT?","answer":"The CY7C1312KV18 series includes density and speed variants within the same 165-FBGA footprint, but a drop-in replacement from another manufacturer is not confirmed.

While the package and pinout may be similar within the same density family, the electrical interface and control-logic handshake differ. A direct replacement would require a board respin and FPGA timing revalidation. Stick with the QDR II variant unless you are planning a full design revision."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1312KV18-300BZXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1312KV18-300BZXCT when reusing this data.
