That 15 ns access time is the window a read-enable assertion must hold before data appears on the outputs — tight enough to keep a 50 MHz synchronous bus fed without wait states, but it leaves no margin for long PCB traces or slow-logic glue. The part operates from a 4.5 V to 5.5 V supply, draws 65 mA maximum, and is rated for 0 °C to 70 °C commercial environments — think bench test gear, office telecom line cards, or lab data-acquisition buffers, not outdoor or under-hood installations. ## Retransmit and expansion — where it matters The CY7C425-15JXCT supports retransmit capability — a feature that lets the FIFO re-read data from the first-in location without a full reset, useful in packet retry or error-recovery loops. Expansion is supported in both depth and width, so multiple devices can cascade to build larger buffers. No programmable flags and no FWFT (First-Word Fall-Through) support, meaning the flag logic is fixed and the first word does not appear on the outputs until a read cycle — typical for simpler asynchronous FIFO designs where the controller manages the handshake.","metaTitle":"Cypress CY7C425-15JXCT Asynchronous FIFO, 15ns, 9K, 32-PLCC","metaDescription":"Cypress CY7C425-15JXCT asynchronous FIFO: 15 ns access time, 9K (1K x 9) memory, 50 MHz data rate, 32-PLCC.
