300 MHz QDR II — what the speed grade delivers
This is a 300 MHz QDR II (Quad Data Rate) synchronous SRAM organized as 8M x 9 bits, giving 72Mbit total density. The QDR II architecture provides separate read and write data ports, eliminating bus-turnaround dead cycles that plague common-I/O SRAMs. At 300 MHz, the device delivers back-to-back read and write throughput without wait states — critical for high-bandwidth buffer applications in network switches, routers, and telecom line cards where every clock cycle counts.
Supply and temperature — fit for controlled environments
Operates from a 1.7V to 1.9V core supply, which aligns with the lower-voltage I/O standards common in 90nm and 65nm ASIC/FPGA designs.
Package and footprint — 165-FBGA (13x15 mm)
Housed in a 165-ball FBGA measuring 13x15 mm (supplier device package 165-FBGA). Surface-mount only. The fine-pitch BGA requires careful PCB layout with via-in-pad or microvia fanout for the dense ball array.
