What this QDR II+ SRAM does at 550 MHz
Its 550 MHz clock rate delivers back-to-back read and write operations without the dead cycles that plague older DDR SRAMs — the bus never stalls on turnaround. That matters for high-throughput pipelines in network processors, line cards, and test equipment where every clock cycle carries data.
Runs on a 1.7V to 1.9V core supply, which keeps I/O levels compatible with 1.8V logic families common on modern ASICs and FPGAs.
Marked as EOL hot in the lifecycle stage — Cypress has issued an end-of-life notice, and last-time-buy windows are closing or closed. The part is still listed as active in product status, but the EOL flag tells the procurement team to move now.
