250 MHz synchronous SRAM for high-throughput data buffers
The Infineon Cypress CY7C1442KV33-250AXC is a 36 Mbit synchronous SRAM organized as 2M x 18, clocked at 250 MHz with a 2.6 ns access time.
2.6 ns access — what it buys on the bus
The 2.6 ns access time at 250 MHz clock means the part can deliver data within one clock cycle from address assertion in a pipelined read. For a system architect sizing a FIFO or look-up table between a 250 MHz FPGA and a network processor, this timing leaves enough setup-and-hold margin to avoid adding wait states. The 2M x 18 organization suits 18-bit wide data paths common in telecom backplanes and switch fabrics.
For a procurement buyer qualifying a BOM line, there is no forced migration risk. The base product number is CY7C1442, and the -250AXC suffix denotes the 250 MHz speed grade in a 100-TQFP tray package.
