The CY7C42X1V are high-speed, low-power, FIFO memories with clocked read and write interfaces. All are nine bits wide. Programmable features include Almost Full/Almost Empty flags. These FIFOs provide solutions for a wide variety of data buffering needs, including high-speed data acquisition, multiprocessor interfaces, and communications buffering. These FIF.
