CY7C4282 - Cypress Semiconductor

CY7C4282 (CY7C4282 / CY7C4292) 64K/128K x 9 Deep Sync FIFOs

The CY7C4282/CY7C4292 are high-speed, low-power, FIFO memories with clocked read and write interfaces. All devices are nine bits wide. The CY7C4282/CY7C4292 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 a.
