QDR II (Quad Data Rate) eliminates the dead bus-turnaround cycles that standard synchronous SRAMs incur when switching between read and write — the separate read and write ports let you pipeline back-to-back transactions at full clock rate. That matters in network packet buffers, test equipment capture memories, and any design where the bus cannot stall for a turnaround cycle. ## 250 MHz — timing margin and bus throughput At 250 MHz the clock period is 4 ns. With QDR II's double-data-rate on both read and write ports, the effective data rate per pin is 500 Mbps. The 18-bit-wide data bus delivers a raw bandwidth of 9 Gbps. For the layout engineer, the 165-FBGA (13x15 mm) footprint requires controlled-impedance traces and matched-length routing on the clock and strobe lines to hold setup/hold margins. The supply tolerance (1.7V–1.9V) is tight — a 1.8V rail with ±3% regulation is the practical choice; a switching regulator with 50 mV ripple will eat into the timing budget. For a BOM cost engineer, that means no forced redesign cycle from a supplier-initiated EOL. Because QDR II parts have a narrower second-source base than commodity DDR SRAM, locking in a supply agreement for production volumes is worth the conversation now rather than during an allocation window.","metaTitle":"Cypress CY7C1313KV18-250BZXI QDR II SRAM, 18Mbit, 250 MHz","metaDescription":"Cypress CY7C1313KV18-250BZXI QDR II synchronous SRAM, 18Mbit (1Mx18), 250 MHz clock, 1.7-1.9V, -40 to 85°C, 165-FBGA.

The key difference from QDR II+ is the maximum clock frequency: QDR II+ supports higher clock rates (typically 550 MHz and above) and adds a programmable impedance output driver. The CY7C1313KV18-250BZXI tops out at 250 MHz, which is squarely in the QDR II performance tier. If your design needs a faster clock, look at the CY7C1313KV18-550BZXI (QDR II+) — but verify pin compatibility; the footprints differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1313KV18-250BZXI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1313KV18-250BZXI when reusing this data.
