500 MHz QDR II+ SRAM — what this part is and where it fits
The Cypress CY7C25652KV18-500BZC is a 72 Mbit synchronous SRAM built on the QDR II+ architecture, organized as 2M × 36. It clocks at 500 MHz on the parallel interface, delivering the bandwidth needed for high-throughput data buffers in network line cards, test instrumentation, and FPGA-attached scratchpad memory. The 1.7 V to 1.9 V core supply and 165-ball FBGA (13 × 15 mm) package target controlled indoor environments — the 0 °C to 70 °C commercial temperature range keeps it out of unheated cabinets and outdoor enclosures.
Footprint and interface — what to verify before layout
The 165-ball FBGA (13 × 15 mm) uses a QDR II+ ball map with separate read and write data ports. Verify ball assignment against the controller.
