450 MHz QDR II+ — the bandwidth ceiling for this SRAM
The CY7C25632KV18-450BZC is a 72 Mbit synchronous SRAM built on the QDR II+ architecture, clocked at 450 MHz. At this frequency the device delivers back-to-back read and write operations on separate data ports, eliminating the bus-turnaround dead cycles that limit single-port SRAM throughput. The 4M x 18 organization (72 Mbit total) suits high-bandwidth data buffering in network switches, line cards, and compute accelerators where the memory must keep pace with the packet or data rate without stalling the pipeline.
Core supply spans 1.7 V to 1.9 V, a single-rail design that simplifies the power tree — no separate VDDQ or VREF plane needed. The 165-ball FBGA package (13x15 mm) uses a 1.0 mm ball pitch — a standard 4- or 6-layer PCB with via-in-pad can route the full signal set, but the inner-row balls require micro-vias or dog-bone fan-out if the layer count is tight.
