CY7C4291 Description
CY7C4281 CY7C4291 64K/128K x 9 Deep Sync FIFOs .
The CY7C4281/91 are high-speed, low-power FIFO memories with clocked read and write interfaces.
CY7C4291 Features
* High-speed, low-power, first-in first-out (FIFO) memories
* 64K × 9 (CY7C4281)
* 128K × 9 (CY7C4291)
* 0.5-micron CMOS for optimum speed/power
* High-speed 100-MHz operation (10-ns read/write cycle times)
* Low power
* ICC= 40 mA
CY7C4291 Applications
* Clock frequencies up to 100 MHz are achievable. Depth expansion is possible using one enable input for system control, while the other enable is controlled by expansion logic to direct the flow of data. Logic Block Diagram
