Product Summary

The CY7C403-10PC is a kind of asynchronous first-in first-out (FIFO) organized as 64 four-bit words. The CY7C403-10PC accepts 4- or 5-bit words at the data input (DI0 – DIn) under the control of the shift in (SI) input. Reading and writing operations are completely asynchronous, allowing the CY7C403-10PC to be used as a buffer between two digital machines of widely differing operating frequencies. The 25-MHz operation makes the CY7C403-10PC ideal for high-speed communication and controller applications.
