This density and speed target high-throughput applications like network packet buffers, test-equipment waveform memories, and FPGA look-aside caches where the read and write ports run independently on every clock edge. ## Obsolete — sourcing through independent surplus channels Infineon lists this part as Obsolete. The 165-ball FBGA (13x15 mm) ball-out is fixed; a board spin would be required to migrate to a different package or memory architecture. ## 1.8 V core rail and industrial temperature grade The supply range is 1.7 V to 1.9 V — a single 1.8 V rail with ±0.1 V tolerance covers it, but the PCB must hold that rail tight under load transients.","metaTitle":"Infineon CY7C2563KV18-450BZXI 72Mbit QDR II+ SRAM, 450 MHz","metaDescription":"72Mbit QDR II+ synchronous SRAM, 4M x 18, 450 MHz clock, 165-FBGA.
