72 Mbit QDR II SRAM at 400 MHz — the throughput driver
Its 400 MHz clock rate delivers back-to-back read and write transactions on every clock edge without dead cycles, which is the defining characteristic for high-bandwidth buffer applications in networking switches, telecom line cards, and test equipment. The 1.7V to 1.9V core supply aligns with low-voltage logic families common in 1.8V-dominated systems.
For existing BOM lines or repair stock, the only supply channel is independent distribution, where units are sourced from surplus inventory or last-time-buy overruns.
165-ball FBGA — layout and rework considerations
Surface-mount assembly requires a controlled reflow profile consistent with JEDEC MSL ratings for BGA packages. The fine-pitch ball array demands careful PCB layout for signal integrity at 400 MHz, including matched trace lengths for the QDR II data and address buses, and adequate decoupling capacitance placed close to the supply balls.
Commercial temperature range — limits deployment
It is not specified for industrial or automotive temperature extremes without additional thermal management.
