The 36-bit data word is a single-cycle read or write on the rising and falling edges of the clock — QDR II+ architecture delivers two data transfers per clock cycle, so the 300 MHz clock yields a 600 MT/s data rate per I/O pin. At 300 MHz, the read-to-write turnaround is one clock cycle. The burst length is fixed at 4, and the device supports both single-address and interleaved burst sequences. The parallel memory interface means the address and control lines are shared across the 36-bit data bus — layout must match the trace-length skew budget for the full 300 MHz timing window. ## Supply rails and temperature grade Core supply is 1.7V to 1.9V — a 1.8V nominal rail with ±5.5% tolerance. ## Sourcing posture The CY7C2644KV18-300BZI is sourced through independent distribution channels.","metaTitle":"Infineon CY7C2644KV18-300BZI QDR II+ SRAM, 144Mbit, 300 MHz","metaDescription":"Infineon CY7C2644KV18-300BZI QDR II+ synchronous SRAM, 144Mbit (4M x 36), 300 MHz, 1.7-1.9V, -40 to 85°C, 165-FBGA.
