Functional Description
The CY7C419, CY7C420/1, CY7C424/5, CY7C428/9, and CY7C432/3 are first-in first-out (FIFO) memories offered in 600-mil wide and 300-mil wide packages. They are, respectively, 256, 512, 1,024, 2,048, and 4,096 words by 9-bits wide. Each FIFO memory is organized such that the data is read in the same sequential order that it was written. Full and Empty flags are provided to prevent overrun and underrun. Three additional pins are also provided to facilitate unlimited expansion in width, depth, or both. The depth expansion technique steers the control signals from one device to another in parallel, thus eliminating the serial addition of propagation delays, so that throughput is not reduced. Data is steered in a similar manner.
