This is the part for high-bandwidth, low-latency data buffering in networking gear, test equipment, and signal processing where the bus can't stall. The QDR II architecture delivers independent read and write data ports, doubling throughput per clock cycle compared to a traditional synchronous SRAM. The 250 MHz clock means the memory interface runs at a 500 MHz data rate on the DDR bus — the PCB layout must keep trace lengths matched and impedance controlled across the 36-bit data bus. ## Package and supply — what the board sees The 1.7–1.9 V core supply is tight — the regulator must hold within 100 mV of the nominal 1.8 V rail, especially under load transients from the 250 MHz switching core. Commercial temperature range (0–70 °C) limits it to indoor, controlled-environment systems; no extended temp or automotive grade. The 165-FBGA footprint requires a multi-layer PCB with microvia fan-out under the BGA. Decoupling capacitors should sit within 2 mm of the BGA pads on the same layer as the vias to keep loop inductance low at 250 MHz. ## Obsolete — sourcing reality for the BOM line This part is no longer available through franchised distribution channels. Quantities are lot-specific; each lot is verified for authenticity and traceability before quoting. The 165-FBGA package and 250 MHz timing mean any substitute would require a board spin — there is no drop-in alternative.","metaTitle":"CY7C1314BV18-250BZC Infineon QDR II SRAM, 18Mbit, 250 MHz","metaDescription":"CY7C1314BV18-250BZC Infineon QDR II SRAM, 18Mbit (512K x 36), 250 MHz, 1.7-1.9V, 165-FBGA.
