The Infineon CY7C1512KV18-300BZIT is a 72Mbit synchronous SRAM built on QDR II architecture — a double-data-rate design that eliminates bus-turnaround dead cycles by dedicating separate read and write ports. The 300 MHz clock rate, combined with the QDR II protocol, delivers sustained bandwidth that a standard synchronous SRAM at the same frequency cannot match because it never stalls for bus direction changes. Organized as 4M x 18 bits, the part uses a parallel memory interface and operates from a 1.7V to 1.9V supply rail.
At 300 MHz the QDR II interface delivers a 600 MHz data rate on each port because data is clocked on both edges. For a 4M x 18 configuration, that translates to roughly 10.8 Gbps of aggregate read-write bandwidth. The practical takeaway for a system architect: this part keeps a 64-bit or wider bus fed without wait states, provided the controller's memory interface can sustain the rate. Timing closure at this speed demands controlled-impedance PCB traces and careful decoupling — the 165-FBGA's fine-pitch balls help keep signal lengths short.
