The CY7C4225V-15ASC: Synchronous FIFO memory, 18K deep organised as 1K words by 18 bits. Clocks data in and out at up to 66.7 MHz, with an 11 ns access time.
No last-time-buy window remains open through the factory channel.
The evidence does not list a direct pin-compatible replacement. Cypress produced several synchronous FIFOs in the CY7C family with similar 64-LQFP footprints and 3.3 V operation, but verifying pin compatibility requires comparing the datasheet pinout for the exact density and speed grade you need. For an obsolete part, the safest path is to confirm the layout against a candidate datasheet before ordering.
It belongs to the Cypress CY7C series of synchronous FIFO memories.
The device ships in a 64-LQFP package, supplied in Tray format. The supplier device package is 64-TQFP (10x10 mm).
