It clocks at 333 MHz on a parallel interface, which means back-to-back read-write transactions with zero dead cycles — no bus-turnaround penalty. That throughput matters in high-bandwidth data-path designs like network switches, base stations, and test equipment where every clock edge carries a valid word. The supply range is 1.7 V to 1.9 V, typical for the QDR II generation, and the part is housed in a 165-ball FBGA (13x15 mm) — a fine-pitch BGA that demands controlled reflow and X-ray inspection during assembly.
Lifecycle status — end-of-life, no official successor
The CY7C1315KV18-333BZXC is flagged as end-of-life (hot). For a BOM that requires this exact speed grade and density, the procurement path is last-time-buy or surplus-channel sourcing.
That limits this SRAM to indoor, temperature-controlled environments: server rooms, telecom central offices, lab instrumentation. Not suitable for outdoor or industrial enclosures without active cooling.
