The CY7C1315BV18-200BZXC is an 18 Mbit QDR II synchronous SRAM organized as 512K x 36, clocked at 200 MHz. QDR II architecture eliminates bus-turnaround dead cycles by dedicating separate read and write data ports, so back-to-back throughput hits the full 200 MHz rate without idle cycles. That makes it a fit for high-bandwidth buffer applications in network switches, telecom line cards, and test equipment where sustained read-write throughput matters more than density.
Temperature grade limits the deployment environment
That means indoor, temperature-controlled equipment only – server rooms, central offices, lab instrumentation. Not rated for industrial enclosures, outdoor cabinets, or any environment where ambient can drift outside that window.
