36 Mbit QDR II at 250 MHz — bandwidth and latency
The CY7C1425KV18-250BZC: Organized 4M x 9, this QDR II synchronous SRAM clocks at 250 MHz, delivering the double-data-rate throughput needed for high-bandwidth lookup tables and packet buffers in networking line cards and telecom infrastructure. The parallel memory interface and 1.7–1.9 V core supply align with the voltage rail common in 1.8 V logic systems — no extra level translation between the SRAM and the ASIC or FPGA.
Industrial temperature range and package footprint
Rated for -40 to 85 °C ambient, the device suits outdoor base-station and industrial controller environments where the enclosure sees diurnal temperature swings well below 0 °C. Housed in a 165-LBGA (13x15 mm FBGA), the package requires a multi-layer PCB with controlled-impedance traces for the 250 MHz clock and data lines — the ball pitch and footprint are the primary layout constraint.
