72 Mbit QDR II+ SRAM — what the 333 MHz clock buys you
It clocks at 333 MHz on a parallel interface, which means back-to-back read-write transactions with zero dead cycles — the bus never stalls between operations. That throughput matters for deep-packet buffers in network line cards, traffic managers, and telecom baseband processors where every clock cycle of access latency costs bandwidth.
Industrial temperature and the 165-FBGA footprint
Surface-mount only, and the Tray shipping medium tells you this is a production-quantity part, not a sample reel.
Active lifecycle — no end-of-life clock ticking
Infineon (formerly Cypress) lists this part as Active. For a memory device that often stays on a BOM for five to seven years, an Active status removes one sourcing headache. The base product number CY7C25442 covers the density and interface family, so if a speed or package variant is needed later, the roadmap stays within the same qualification envelope.
