Infineon CY7C4235-15AC

36K (2K x 18)66,7 МГц0°C ~ 70°C

Overview

The CY7C42X5 are high-speed, low-power, first-in first-out (FIFO) memories with clocked read and write interfaces. All are 18 bits wide and are pin/functionally compatible toIDT722x5. The CY7C42X5 can be cascaded to increase FIFO depth. 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.
