XR17C154 5V PCI BUS QUAD UART
The XR17C1541 (154) is a quad PCI Bus Universal Asynchronous Receiver and Transmitter (UART) with same package and pin-out as the Exar XR17x158 octal UARTs. The device is designed to meet today’s 32-bit PCI Bus and high bandwidth requirements in communication systems. The global interrupt source register provides a complete interrupt status indication for all 4 channels to speed up interrupt parsing. Each UART is independently controlled and has its own 16C550 compatible 5G register set, transmit and receive FIFOs of 64 bytes, fully programmable transmit and receive FIFO trigger levels, transmit and receive FIFO level counters, automatic hardware flow control with programmable hysteresis, automatic soft-ware (Xon/Xoff) flow control, IrDA (Infrared Data Association) encoder/decoder, 8 multi-purpose definable inputs/outputs, and a 16-bit general purpose timer/counter.
