This is a double-data-rate device — data transfers on both clock edges — effectively delivering a 500 MT/s interface over a parallel 36-bit bus. It's built for the line-rate buffering and look-aside cache roles in networking gear, test equipment, and baseband processing where QDR-style read-write turnaround isn't needed but raw sequential throughput is. The 1.7V to 1.9V core supply keeps I/O power manageable at these edge rates. At 250 MHz the part delivers a 500 MT/s data rate on a 36-bit bus, which works out to roughly 2.25 GB/s of raw bandwidth. That's enough to keep a 10 GbE MAC's packet buffer fed without stalling or to service a high-speed ADC's sample stream in real time. The DDR II interface means the address and control bus runs at the single-edge clock rate, so the controller needs a DDR-capable memory controller — not every FPGA or ASIC has one. The 165-ball FBGA (13x15 mm) footprint is a fine-pitch BGA — ball pitch is 0.65 mm, so the PCB needs micro-via or at least a tight via-in-pad strategy for the inner rows. The supply voltage window is 1.7V to 1.9V, which is tighter than a standard 1.8V rail; a precision LDO or a DC-DC with good load regulation is recommended. Decoupling should follow the layout guidelines in the datasheet: a 0.1 µF ceramic per supply ball pair, plus a bulk 10 µF on the board. Infineon (formerly Cypress) continues to manufacture this DDR II SRAM family, and there is no announced last-time-buy. For dual-source resilience, the part is pin-compatible with other members of the CY7C1320KV18 density and speed variants — the same 165-ball FBGA footprint and 1.7V-1.9V supply — so a speed-bin or density change doesn't force a board spin.","metaTitle":"CY7C1320KV18-250BZXC Infineon 18Mbit DDR II SRAM, 250 MHz","metaDescription":"CY7C1320KV18-250BZXC Infineon 18Mbit synchronous DDR II SRAM, 250 MHz clock, 512K x 36, 1.7-1.9V, 165-FBGA.
