450 MHz QDR II+ SRAM for high-throughput systems
Infineon's CY7C15632KV18-450BZXI is a 72 Mbit QDR II+ synchronous SRAM organized 4M x 18, clocked at 450 MHz. The QDR II+ architecture delivers separate read and write data ports, eliminating bus-turnaround dead cycles and sustaining full-rate back-to-back transactions — a requirement in network packet buffers, search engines, and high-end FPGA compute accelerators. The parallel memory interface and 1.7V to 1.9V core supply align with the I/O banks on modern FPGAs and ASICs.
Industrial temperature qualification
The 165-FBGA (13x15 mm) package keeps the signal path short for 450 MHz operation; the 1.7V to 1.9V supply range also covers the lower end of typical FPGA VCCIO rails. MSL and bake requirements follow the FBGA standard — plan for moisture sensitivity handling before reflow.
Active status — no LTB risk on the BOM line
No end-of-life notification, no last-time-buy window to track. The base product number CY7C15632 covers the wider density and speed variants should a future speed-grade migration be needed.
