Product Summary

The CY7C4211-15AC is a high-speed, low-power FIFO memory with clocked Read and Write interfaces. The CY7C4211-15AC is 9 bits wide. The CY7C4211-15AC is pin-compatible to IDT722X1. Programmable of the CY7C4211-15AC features include Almost Full/Almost Empty flags. These FIFOs of the CY7C4211-15AC provide solutions for a wide variety of data buffering needs, including high-speed data acquisition, multiprocessor inter-faces, and communications buffering. These FIFOs of the CY7C4211-15AC have 9-bit input and output ports that are controlled by separate clock and enable signals. The input portis of the CY7C4211-15AC controlled by a free-running clock (WCLK) and twoWrite-enable pins.
