The CY7C429-10AXC is a 2K x 9 asynchronous FIFO from the CY7C series. It operates at 50 MHz with a 10 ns access time.
The retransmit capability lets the FIFO re-output stored data without a full reset. The 9-bit width carries a parity or control bit.
The access time is 10 ns, which at a 50 MHz data rate leaves roughly half the bus cycle for setup and hold in a 5 V system.
No pin-compatible direct replacement is listed. A functional substitute would require a different density or width from the CY7C series, necessitating a board layout change.
