In DDR II mode, data is transferred on both edges of the clock, giving a peak bandwidth of 2.25 GB/s across the 36-bit bus — enough to feed a high-end network processor or FPGA without stalling the pipeline. The 1.7 V to 1.9 V core supply lets it sit on a 1.8 V nominal rail with margin for droop. The parallel interface means the address and control lines share the same voltage domain as the core, so no external level translator is needed if the controller also runs at 1.8 V. ## Package, temperature grade, and board integration Housed in a 165-ball FBGA measuring 13 x 15 mm, the part is a direct fit for high-density memory arrays on multi-layer PCBs. The 0.80 mm ball pitch is standard for this density class — a four-layer board with via-in-pad or dogbone fan-out handles the routing without microvias. That covers most indoor networking, telecom, and test equipment, but it is not rated for extended industrial or automotive ambient. If the board sees 85°C in the enclosure, this part is not the right call. Supplied on Tape & Reel, the part is ready for pick-and-place assembly. That means it is still a valid choice for new designs, and there is no forced migration risk in the near term. No stock-holding claim — the part is procured per BOM quantity.","metaTitle":"CY7C1321KV18-250BZCT 18Mbit DDR II SRAM, 250 MHz, 165-FBGA","metaDescription":"Infineon CY7C1321KV18-250BZCT 18Mbit synchronous DDR II SRAM, 512K x 36, 250 MHz clock, 1.7-1.9V, 165-FBGA.
