72 Mbit QDR II SRAM — 167 MHz synchronous buffer
The Infineon CY7C1512AV18-167BZI is a 72 Mbit synchronous SRAM built on the QDR II architecture, organized as 4M x 18. The 167 MHz clock rate delivers back-to-back read and write transactions without the dead cycles that plague traditional DDR SRAM — a key advantage for high-throughput networking equipment, telecom line cards, and FPGA-based signal-processing pipelines that need deterministic latency and full bus utilization. The parallel interface and 1.7 V to 1.9 V core supply place it in the high-performance buffer tier, not the low-power standby class.
