The 333 MHz clock rate delivers a peak bandwidth of 2.664 Gbytes/s on a 36-bit data bus, which is the throughput tier that network processors, FPGA-based packet buffers, and telecom line cards demand. The QDR II architecture separates read and write data ports, eliminating bus-turnaround dead cycles that conventional synchronous SRAMs incur — every clock edge can carry a new transaction.
The 165-ball LBGA (supplier device package 165-FBGA, 13x15 mm body) is the footprint for this density and speed grade. Verify the land pattern against the Cypress package drawing before committing the PCB layout.
Last-time-buy — order window is open
Cypress has placed the CY7C1414KV18-333BZXI into Last Buy status. This means the final production run is scheduled, and once the LTB window closes, the part will no longer be manufactured. Procurement teams should place their final quantity orders now to cover the remaining product lifecycle. The closest functional peer is the CY7C1415KV18-300BZXC, but that part runs at 300 MHz (versus 333 MHz) and is commercial temperature only — it is not a pin-compatible or spec-equivalent replacement. For new designs or bridge orders, the independent distribution channel can source this part against an RFQ while the LTB window is active.
