Cypress CY7C4261-10JI

64K x 9100 МГц-40°C ~ 85°C

Overview

The CY7C4261/71 are high-speed, low-power FIFO memories with clocked read and write interfaces. All are nine bits wide. The CY7C4261/71 are pin-compatible to the CY7C42X1 Synchronous FIFO family. The CY7C4261/71 can be cascaded to increase FIFO width. 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.
