Cypress CY7C4281V-10JXC

576K (64K x 9)100 МГц0°C ~ 70°C

Overview

The CY7C4281/91 are high-speed, low-power FIFO memories with clocked read and write interfaces. All are nine bits wide. The CY7C4281/91 are pin-compatible to the CY7C42X1 Synchronous FIFO family. 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.
