The CY7C1314KV18-250BZC: It clocks at 250 MHz, which means the memory delivers four data words per clock cycle — two reads and two writes — for a peak bandwidth of 18 Gbit/s on a 36-bit bus. This class of SRAM lives in high-throughput datapaths: network switch buffers, telecom line cards, and FPGA-attached lookup tables where the bus can't stall for a read-write turnaround. The 1.7V to 1.9V core supply keeps I/O compatible with 1.8V logic families common on modern ASICs and FPGAs.
Last Buy — the sourcing clock is ticking
Last Buy status — Cypress has issued a last-time-buy notice. The 165-ball FBGA footprint (13x15 mm) is specific to the QDR II family.
The 165-LBGA (13x15 mm) is a fine-pitch BGA. Reballing or replacement on a rework station is possible, but the 0.8 mm ball pitch demands a good bottom-side preheat profile and a stencil aligned to the FBGA footprint. If your board sees ambient above 70°C, you need a wider-temperature variant or a different SRAM family.
