Functional Description
The CY7C42X1 are high speed, low power FIFO memories with clocked read and write interfaces. All are 9 bits wide. The CY7C42X1 are pin-compatible to IDT722X1. 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.
