250 MHz DDR II SRAM for high-throughput line cards
The Infineon CY7C1420KV18-250BZXC is a 36Mbit DDR II synchronous SRAM organized as 1M x 36, clocked at 250 MHz, and supplied at 1.7V to 1.9V. This is a double-data-rate device — data transfers on both edges of the clock — which effectively doubles the bandwidth per pin compared to a single-data-rate SRAM at the same frequency. The 165-ball FBGA (13x15 mm) footprint keeps the signal path short but demands a controlled-impedance PCB stackup and careful BGA rework planning.
