The QDR II+ architecture separates read and write ports, delivering back-to-back throughput without bus-turnaround penalties.
This limits deployment to indoor, climate-controlled environments: central offices, data centers, lab instrumentation. Not rated for industrial enclosures or outdoor telecom cabinets without active cooling or extended-temperature qualification.
The part is supplied in a 165-ball LBGA (165-FBGA, 13x15 mm body) on Tray.
It is a synchronous QDR II+ SRAM — a volatile memory with separate read and write ports for high-throughput, no-bus-turnaround operation.
