The Infineon CY7C25422KV18-333BZXI is a 72 Mbit QDR II+ synchronous SRAM organized 2M x 36, clocked at 333 MHz. The QDR II+ architecture eliminates dead cycles on the data bus by dedicating separate read and write ports, so back-to-back transactions sustain the full 333 MHz rate without bus-turnaround penalties.
This part is in Last Buy status. Infineon has announced a final order window; after that date the factory will not accept new orders. Any design currently using the CY7C25422KV18-333BZXI needs a last-time-buy plan to cover the remaining production run, plus a bridge or replacement strategy for post-EOL service.
Given the Last Buy status, early engagement is recommended to secure allocation before the final order cut-off.
