EXAR  XR17D158IV-F  接口, UART, 8通道, 6.25 Mbps, 3 V, 5.5 V, LQFP, 144 引脚

The is an octal PCI Bus Universal Asynchronous Receiver and Transmitter UART with support for PCI bus universal VIO buffers. The device is designed to meets the 32-bit PCI bus and high bandwidth requirement in communication systems. A global interrupt source register provides a complete interrupt status indication for all 8 channels to speed up interrupt parsing. Each UART has its own 16C550 compatible set of configuration registers, transmit and receive FIFOs of 64-bytes, fully programmable transmit and receive FIFO level trigger levels, transmit and receive FIFO level counters, automatic RTS/CTS or DTR/DSR hardware flow control with programmable hysteresis levels, automatic software Xon/Xoff flow control, IrDA Infrared Data Association encoder/decoder, 8 multi-purpose inputs/outputs and a 16-bit general purpose timer/counter.
