The Cypress Semiconductor CY7C421-25VC is a high-speed asynchronous first-in first-out (FIFO) buffer memory. It offers a storage capacity of 512 words by 9 bits wide, ensuring data is read in the same sequential order it was written.
Key features include a high operating frequency of 50 MHz, independent of depth or width, and low operating power with ICC typically at 35 mA. The device provides Full and Empty flags to prevent data overrun and underrun conditions. It is TTL compatible, facilitating integration into various digital systems.
Designed for flexibility, the CY7C421-25VC supports expansion in width and depth. It is available in multiple package types including PLCC, 7x7 TQFP, SOJ, and both 300-mil and 600-mil DIP packages, making it suitable for a wide range of board designs and applications.
This FIFO memory is pin compatible and functionally equivalent to parts from IDT and AMD, such as the IDT7200 series and AM7200 series.
