Clocked at 450 MHz, it delivers back-to-back read/write throughput without dead cycles on the bus, which is the key requirement for high-bandwidth packet buffers in telecom line cards, network switches, and test equipment.
The CY7C1168KV18-450BZC is officially marked as Obsolete by Infineon.
The footprint is standard for this density class, but any board respin should verify the ball map against the existing layout if cross-shopping a replacement.
The best path is to source the original part from independent inventory or evaluate a functionally equivalent DDR II+ SRAM from the same or alternate supplier, verifying the footprint and timing compatibility.
