This manual provides a detailed introduction to the CY7C419/21/25/29/33 Asynchronous FIFO devices' function, features and usage methods.
The document describes the CY7C419, CY7C420/1, CY7C424/5, CY7C428/9, and CY7C432/3 series of first-in first-out (FIFO) memories. These devices are organized as 256, 512, 1,024, 2,048, and 4,096 words by 9-bits wide, respectively. They feature a dual-ported RAM cell structure and operate at high speeds up to 50.0 MHz for read and write operations independently of depth and width.
