Description

The XR17C1581 (158) is an octal Universal Asynchronous Receiver and Transmitter (UART). The device is designed to meet the 32-bit PCI Bus and high bandwidth requirement in communication systems. The 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 triggers, transmit and receive FIFO level counters, automatic RTS/CTS or DTR/DSR hardware flow control with programmable hysteresis, automatic software (Xon/Xoff) flow control, IrDA (Infrared Data Association) encoder/decoder, 8 multi-purpose definable inputs/outputs, and a 16-bit general purpose timer/counter.

NOTE: 1 Covered by U.S. Patents #5,649,122 and #5,949,787



Description

The XR17C1581 is an eight-channel PCI Bus Universal Asynchronous Receiver and Transmitter (UART) with same package and pin-out as Exar's XR17C154 quad UART. 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 eight 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 software (Xon/Xoff) flow control, IrDA (Infrared Data Association) encoder/decoder, 8 multi-purpose definable inputs/outputs, and a 16-bit general purpose timer/counter.

NOTE: 1Covered by U.S. Patents #5,649,122, #5,832,205
