It clocks at 250 MHz, meaning data transfers on both edges of the clock for an effective 500 MT/s throughput on a 18-bit-wide bus. This class of memory is typically specified for high-bandwidth, low-latency applications such as network packet buffers, telecom line cards, test equipment waveform storage, and high-end FPGA cache where the deterministic access time of SRAM beats DRAM's refresh overhead. ## Supply rail tolerance — the 200 mV window That means the PCB's power rail feeding this SRAM needs a regulator with better than ±5% accuracy — a standard 1.8 V rail at ±3% is fine, but a rail that droops below 1.7 V under load will cause read/write failures. Budget a low-noise LDO or a switching regulator with tight load regulation for this rail. It belongs in office-environment equipment, lab instruments, and climate-controlled telecom shelters. Not specified for outdoor base stations, automotive under-hood, or industrial floor applications without additional system-level thermal management or qualification. Supplied in a 165-ball LBGA (13x15 mm body, 1.0 mm ball pitch typical for this class). Surface-mount BGA requires a solder reflow profile per J-STD-020, X-ray inspection for voiding and shorts, and controlled impedance layout for the 250 MHz clock traces. Infineon lists the CY7C1318KV18-250BZC as Active on its product status.","metaTitle":"CY7C1318KV18-250BZC Infineon 18Mbit DDR II SRAM, 250 MHz","metaDescription":"CY7C1318KV18-250BZC Infineon 18Mbit SRAM - Synchronous DDR II, 250 MHz clock, 1.7V-1.9V supply, 165-FBGA.
