16550 UART w/FIFOs & synch interface
"The CAST H16550S is a standard UART providing 100% software compatibility with the popular Texas Instruments 16550 device. It performs serial-to-parallel conversion on data originating from modems or other serial devices, and performs parallel-to-serial conversion on data from a CPU to these devices. The H16550S can be run in either 16450-compatible character mode or in 16550-compatible FIFO mode, where an internal FIFO relieves the CPU of excessive software overhead. Developed for easy reuse in Xilinx FPGA applications, the H16550S is available optimized for several device families with competitive utilization and performance characteristics.
