The Infineon CY7C1663KV18-450BZXC is a 144 Mbit synchronous SRAM organised as 8M x 18, built on QDR II+ architecture. The 450 MHz clock rate delivers back-to-back read and write operations without bus-turnaround dead cycles — critical for high-throughput packet buffers in network switches, telecom line cards, and high-end test equipment. The parallel interface runs on a 1.7 V to 1.9 V core supply, and the 165-ball FBGA (15x17 mm) footprint matches the standard QDR II+ pinout for this density tier.
This suits indoor equipment in controlled environments: server rooms, central offices, lab instrumentation. Store the reels dry; the FBGA package is moisture-sensitive and requires bake before reflow if the floor life is exceeded.
