XR17D158  
UNIVERSAL (3.3V AND 5V) PCI BUS OCTAL UART  
AUGUST 2005  
REV. 1.2.2  
FEATURES  
GENERAL DESCRIPTION  
High Performance Octal PCI UART  
Universal PCI Bus Buffers - Auto-sense 3.3V or 5V  
Operation  
1
The XR17D158 (D158) is an octal PCI Bus  
Universal Asynchronous Receiver and Transmitter  
(UART) with support for PCI Bus universal VIO  
buffers in the same package and pin-out as the  
XR17C158, XR17C154 and XR17D154. The device  
is designed to meet 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  
32-bit PCI Bus 2.3 Target Signalling Compliance  
A Global Interrupt Source Register for all 8 UARTs  
Data Transfer in Byte, Word and Double-word  
Data Read/Write Burst Operation  
Each UART is independently controlled with:  
16C550 Compatible 5G Register Set  
64-byte Transmit and Receive FIFOs  
Transmit and Receive FIFO Level Counters  
Programmable TX and RX FIFO Trigger Level  
Automatic RTS/CTS or DTR/DSR Flow Control  
Automatic Xon/Xoff Software Flow Control  
RS485 HDX Control Output with Selectable  
Association) encoder/decoder,  
inputs/outputs and a 16-bit general purpose timer/  
counter.

Turn-around Delay  
Infrared (IrDA 1.0) Data Encoder/Decoder  
Programmable Data Rate with Prescaler  
Up to 6.25 Mbps Serial Data Rate
