This is a single-data-rate (SDR) synchronous SRAM—every clock edge latches addresses and controls, making it a fit for high-throughput buffer applications in networking equipment, base stations, and DSP pipelines where deterministic read/write latency matters.

Frequently asked questions
What is the closest pin-compatible alternative to CY7C1441KV33-133BZXI?
No pin-compatible alternative is listed in the record. The 165-FBGA footprint and 1M x 36 organization are specific enough that a drop-in replacement would need to match the same package, clock speed, and supply voltage. Without a documented cross-reference, verify any candidate against the original PCB layout.
