QDR II synchronous SRAM for high-throughput buffers
The CY7C1512KV18-250BZCT is a 72 Mbit QDR II synchronous SRAM organized as 4M x 18 bits, clocked at 250 MHz. The 250 MHz clock rate yields a 4 ns cycle time, which translates to roughly 1.8 GB/s of peak bandwidth on the 18-bit data bus. That throughput is what makes this part viable for line-rate packet processing at 10 GbE or for cache in a high-end FPGA design.
Supply voltage and temperature envelope
The commercial grade is a cost-optimised choice for environments where the ambient stays below 70°C.
Package and PCB integration
The ball pitch is manageable with standard SMT assembly, but rework demands a BGA rework station and a pre-bake to remove moisture per the MSL rating. The supplier device package is 165-FBGA (13x15); the footprint matches the standard QDR II 165-ball layout used across multiple densities in this family, so a board designed for a 36 Mbit part can often take the 72 Mbit with no layout change.
