72Mbit QDR II SRAM — what it is and where it fits
The Infineon CY7C1512AV18-200BZI is a 72Mbit synchronous SRAM using the QDR II architecture, organized as 4M x 18. It runs on a 200 MHz clock with a parallel interface, delivering back-to-back read-write throughput without dead cycles — the QDR II bus eliminates the turnaround penalty that standard DDR SRAM incurs. This makes it a fit for high-bandwidth packet buffers in network switches, lookup tables in telecom line cards, and cache memory in test equipment where sustained random-access throughput matters more than raw density.
Obsolete — sourcing reality
Infineon lists the CY7C1512AV18-200BZI as Obsolete. No official successor order code appears in the lifecycle record. For a BOM line that needs this exact density and bus architecture, the supply path is the surplus and independent-distribution channel. We source and quote it to order against an RFQ; availability and current pricing are confirmed at quote time.
