QDR II+ eliminates the bus-turnaround dead cycles that plague standard synchronous SRAMs, delivering sustained read-write throughput on every clock edge. For a network line card or test instrument that streams data into an FPGA at line rate, this part keeps the pipeline full without wait states. The memory is organized 512K x 36. ## Package and temperature — board-fit constraints","metaTitle":"Infineon CY7C1165KV18-550BZC QDR II+ SRAM, 18Mbit 550 MHz","metaDescription":"Infineon CY7C1165KV18-550BZC 18Mbit synchronous SRAM, QDR II+ architecture, 550 MHz clock, 512K x 36 organization, 1.8V supply, 165-FBGA.
