It clocks at 500 MHz and operates from a 1.7V to 1.9V core supply. The part is designed for high-bandwidth, low-latency data buffering in networking gear, telecom line cards, test equipment, and high-end compute — any system where a fast, predictable SRAM is needed for packet buffers, lookup tables, or cache. The QDR II+ interface delivers back-to-back read and write transactions on every clock edge without dead cycles, which is the key advantage over legacy synchronous SRAMs.
At 500 MHz the data window is tight: the QDR II+ interface uses source-synchronous clocking, so the controller must match the output valid window and setup/hold times from the datasheet. The 165-FBGA (13x15 mm) ball grid array keeps the signal paths short, but the layout needs controlled impedance traces and matched-length routing for the clock and data groups.
It belongs in indoor, temperature-controlled equipment — data centre switches, lab instruments, server blades — not in outdoor cabinets, engine bays, or factory floors where ambient can exceed 70°C.
It is a surface-mount BGA.
