It clocks at 250 MHz, which means the memory can sustain two read and two write operations per clock cycle — effectively quadrupling the data bandwidth compared to a conventional synchronous SRAM running at the same frequency. This part is aimed at high-throughput applications like network packet buffers, DSP coefficient tables, and FPGA block-RAM expansion where every nanosecond of memory latency cuts into the processing budget.
Package and footprint — what the rework bench sees
The 1.7 V–1.9 V supply rail is the only power plane — no separate VDDQ — which simplifies the PCB decoupling layout but means the entire memory core rides on that single low-voltage rail. If you're repairing a board that lost this part, the scorch mark might be subtle; check the supply pins for a short first.
Infineon lists the CY7C1315KV18-250BZI as Active. The BOM risk is low — you're not chasing a sunset part.
