The 250 MHz clock delivers a peak data rate of 1 GB/s on the read and write ports combined — each port transfers two words per clock cycle, so the effective bandwidth is 500 MHz per port. The parallel interface and the QDR II architecture target high-throughput buffer applications — network switches, base stations, and test equipment that need deterministic, low-latency access without the refresh overhead of DRAM. ## Industrial temperature range and supply rails Core supply is 1.7 V to 1.9 V, a narrow ±6% window around the nominal 1.8 V rail. The PCB decoupling plan must keep the supply within this band under transient load; a 1.8 V LDO with <50 mV dropout at the peak current is the usual choice. Infineon lists the CY7C1315KV18-250BZXI as Last Buy — the manufacturer has announced end-of-life and will accept final orders within a defined window. After that date, the part is available only through independent surplus channels. For an active design that already uses this SRAM, the Last Buy status means the procurement team should secure lifetime-buy quantities or qualify a replacement before the window closes. ## Package — 165-FBGA (13x15 mm) The 165-ball FBGA measures 13x15 mm with a 0.80 mm ball pitch — a standard fine-pitch BGA that routes on a 4-layer PCB with microvias. The package is RoHS-compliant and shipped in Tray format.","metaTitle":"CY7C1315KV18-250BZXI QDR II SRAM, 18 Mbit, 250 MHz, Last Buy","metaDescription":"Infineon CY7C1315KV18-250BZXI QDR II SRAM, 18 Mbit (512K x 36), 250 MHz, -40 to 85°C, 165-FBGA.
