The 1.7 V to 1.9 V supply rail aligns with low-voltage core logic, and the industrial temperature range (-40°C to 85°C) covers outdoor telecom cabinets, base stations, and factory-floor controllers where thermal cycling is a given. ## 450 MHz vs 250 MHz — the delta matters for the bus The closest peer, CY7C1515KV18-250BZXI, runs at 250 MHz — half the clock rate. For a design that already closes timing at 250 MHz, the 450 MHz part buys headroom for future throughput scaling or tighter latency budgets. The 450 MHz part also uses the same 1.7 V–1.9 V supply and 165-FBGA footprint, so a board spin to swap densities doesn't require a layout change.","metaTitle":"Cypress CY7C1545KV18-450BZXI QDR II+ SRAM, 72Mbit, 450 MHz","metaDescription":"Cypress CY7C1545KV18-450BZXI QDR II+ synchronous SRAM, 72Mbit, 450 MHz, 1.7–1.9V, 165-FBGA, -40°C to 85°C.
