72Mbit QDR II SRAM — 300 MHz pipeline for high-throughput buffers
It clocks at 300 MHz on the parallel interface, delivering back-to-back read and write operations on separate ports without bus-turnaround dead cycles — the defining advantage of QDR II over conventional synchronous SRAM.
Obsolete — sourcing reality for the BOM line
No last-time-buy window or successor part number is listed in the official record. If your design can tolerate a pin-compatible alternative within the QDR II family, a cross-reference search against the base product number CY7C1513 may yield an active-density or speed-grade variant — though no official second source is recorded for this specific code.
