Description

The CY7C344-25PC is a first-in, first-out (FIFO) memory chip belonging to the CY7C4 series. It is offered in 600-mil wide and 300-mil wide packages, contains 256 words by 9 bits wide, and falls under the IC chips product category. Each FIFO memory is organized in such a way that the data is read in the same order it was written, and full and empty flags are provided to prevent underrun and overrun. The chip also comes with additional pins to facilitate unlimited expansion in width, depth, or both. Data is steered, and throughput is not reduced as a result.
