CY7C408A Overview
The CY7C408A and CY7C409A are 64-word deep by 8- or 9-bit wide first-in first-out (FIFO) buffer memories. In addition to the industry-standard handshaking signals, almost full/almost empty (AFE) and half-full (HF) flags are provided. AFE is HIGH when the FIFO is almost full or almost empty, otherwise AFE is LOW.
