250 MHz QDR II — what it means for throughput
The CY7C1413AV18-250BZCT: This is a QDR II (Quad Data Rate) synchronous SRAM, meaning it transfers data on both rising and falling edges of the clock and on both read and write ports simultaneously. At a 250 MHz clock frequency, the effective data rate per pin is 500 Mbps, giving a peak bandwidth of 9 Gbps on the 18-bit data bus. The 2M × 18 organization (36Mbit total) suits applications needing a wide, fast word — typically packet buffers in network switches, cache for DSPs, or high-speed FIFO replacements. The parallel interface keeps latency low compared to serial memory.
Package and supply rails — layout checklist
This limits the part to indoor, temperature-controlled environments — not suitable for industrial or automotive enclosures without active cooling.
Sourcing reality for an obsolete SRAM
Because the CY7C1413AV18-250BZCT is obsolete, there is no factory lead time to quote. Each procurement lot is sourced from available inventory in the independent channel — quantities are finite and pricing reflects scarcity. We handle the vetting and quote per your BOM line. No direct pin-compatible replacement is listed by Infineon. A cross-ship candidate would need to match the 165-LBGA footprint, 1.8 V core, and QDR II interface — a parametric search against the base number CY7C1413 may yield siblings, but each must be verified for timing and package compatibility.
