The CY7C1514KV18-333BZXI: The 333 MHz clock rate delivers back-to-back read and write transactions on separate data buses — no dead cycles between read-to-write turns, which is the whole point of QDR II. This part is built for high-throughput data buffers in networking line cards, test equipment, and signal-processing pipelines where the memory interface is the throughput bottleneck, not the core logic.
Supply rails and temperature — the operating envelope
Runs on a 1.7V to 1.9V core supply, which is the standard QDR II voltage range. If the design lives in a climate-controlled rack, the commercial-grade sibling would do, but this part already carries the wider range — no reason to derate.
165-ball FBGA — package and rework notes
Rework needs a preheat plate, a controlled reflow profile, and post-placement x-ray to verify ball wetting. The part is MSL-rated per Infineon's standard — check the moisture barrier bag label before baking.
Listed as Active in the lifecycle record — no end-of-life notice, no last-time-buy schedule. For BOM planning, there is no single-source risk from obsolescence on this line.
