Synchronous SRAM for high-bandwidth data paths
The Infineon CY7C1440KV25-250BZXIT is a 36 Mbit synchronous SRAM organized as 1M x 36, clocked at 250 MHz with a 2.6 ns access time. It operates from a 2.375 V to 2.625 V supply and is rated for -40°C to 85°C industrial temperature environments. The 165-ball FBGA package (15x17 mm) is a standard footprint for this density class, used in networking line cards, telecom baseband processors, and DSP cache where wide parallel buses and predictable latency matter more than serial-interface throughput.
250 MHz clock and 2.6 ns access — what they mean for the bus
The synchronous SDR (single-data-rate) interface simplifies timing closure versus DDR variants; the trade-off is half the peak bandwidth per pin. For a design already running a 250 MHz system clock, this part fits without a PLL or DLL to generate a double-rate strobe.
