Functional Description

The CY7C48X1 are Double high-speed, low-power, first-in first-out (FIFO) memories with clocked read and write interfaces. All are 9 bits wide and operate as two separate FIFOs. The CY7C48X1 are pin-compatible to IDT728X1. 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.
