Allare 18 bits wide and are pin/functionally compatible toIDT722x5. The CY7C42X5 can be cascaded to increase FIFOdepth. Programmable features include Almost Full/AlmostEmpty flags. These FIFOs provide solutions for a wide varietyof data buffering needs, including high-speed data acquisition,multiprocessor interfaces, and communications buffering.
