72 Mbit QDR II SRAM at 250 MHz — what the clock rate buys the system
The Infineon CY7C1525KV18-250BZXI is a 72 Mbit synchronous QDR II SRAM organized 8M x 9, clocked at 250 MHz over a parallel interface. That clock rate defines the peak read/write bandwidth the memory controller must budget for — at 250 MHz the QDR II architecture delivers back-to-back transactions on every edge, eliminating dead cycles between read and write turns. For a system architect sizing a high-throughput data buffer (network processor, radar signal chain, test equipment), the 250 MHz rating sets the minimum acceptable controller timing closure and trace-length matching across the 165-ball FBGA footprint.
The 13 mm x 15 mm FBGA body uses a standard BGA array.
For the procurement buyer evaluating a BOM line, this carries no last-time-buy deadline and no forced alternate qualification.
