Operates from 4.5 V to 5.5 V supply, rated 0°C to 70°C. ## Where it fits — applications and environments This FIFO sits between a data source (ADC, DSP, or parallel bus) and a processing element that cannot tolerate back-pressure. Typical use cases include rate-matching between asynchronous clock domains, temporary storage in data acquisition front-ends, and elastic buffering in telecom line cards. The 64-LQFP package is surface-mount, so rework requires hot-air or reflow; no socket option for prototyping.","metaTitle":"Cypress CY7C4225-15AC Synchronous FIFO, 66.7 MHz, 10 ns Access","metaDescription":"Cypress CY7C4225-15AC synchronous FIFO, 18K (1K x 18), 66.7 MHz data rate, 10 ns access time, 4.5 V–5.5 V supply, 0°C–70°C.
