The Cypress CY7C1514JV18-250BZXC is a 72 Mbit QDR II synchronous SRAM organized as 2M x 36 bits, clocked at 250 MHz over a parallel interface. QDR II (Quad Data Rate) architecture delivers two read and two write data words per clock cycle, effectively quadrupling the data bandwidth of a conventional synchronous SRAM at the same bus speed. This part is designed for high-throughput, low-latency buffer applications — typically network switches, routers, line cards, and high-end test equipment where the packet buffer or look-up table must sustain back-to-back transactions without dead cycles.
At 250 MHz the QDR II interface delivers two reads and two writes per cycle.
No official successor part number has been published for this exact speed/density/package combination. Any stock remaining in distribution is from overstock, but the part is no longer in production. Buyers should verify date codes and package integrity on receipt, as the last-time-buy window has closed.
Package and temperature — fit checklist
The 165-ball FBGA (15x17 mm) uses a 1.0 mm ball pitch — standard for QDR II devices of this density.
