72Mbit QDR II SRAM at 250 MHz — what the clock rate means for the memory bus
The CY7C1514KV18-250BZI is a 72Mbit Quad Data Rate II synchronous SRAM organized as 2M x 36. The 250 MHz clock drives a read and a write data transfer on each edge, so the memory bus delivers 500 million transactions per second per port — two independent ports (read and write) run simultaneously, each at that rate. That bandwidth matters when the processor or ASIC on the other side of the bus needs to read a lookup table while writing a new result in the same cycle — no arbitration stall.
Industrial temperature and 165-FBGA — board-fit constraints
The parallel memory interface is a 1.8V HSTL-type I/O — the reference voltage Vref must be generated locally with a 0.1% resistor divider, not tapped from the supply rail, to maintain the input threshold accuracy across the temperature range.
