FEATURES
Functional Description
THe CY7C42X1 are high-speed, low-power, first-in first-out (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.
