The 250 MHz clock rate gives back-to-back read and write operations on separate ports without bus-turnaround dead cycles — the defining advantage of QDR over traditional DDR or NoBL SRAMs. This part is designed for high-throughput buffer applications where every cycle counts: network packet processing, line cards, test equipment, and FPGA-based data acquisition that needs deterministic latency and full-rate throughput.
Supply and temperature — the operating envelope
That rules out outdoor, under-hood, or unheated industrial enclosures unless you can guarantee the ambient stays inside that window. If your system lives in a conditioned rack or lab bench, this is fine.
Package reality: 165-FBGA
The 165-FBGA (13x15 mm) is a fine-pitch BGA. No hand-soldering — you need a reflow profile, stencil, and X-ray inspection.
No new factory orders can be placed. The only channel is surplus and broker inventory — which is where we source it.
