5V PCI BUS OCTAL UART  
REV. 1.4.3  
AUGUST 2005  
FEATURES  
GENERAL DESCRIPTION  
High Performance Octal UART  
1
The XR17C158 (158) is an octal Universal  
32-bit PCI Bus Interface with EEPROM Interface  
Interrupt Source Register for all 8 UARTs  
Data Transfer in Byte, Word and Double-word  
Read/Write Burst Operation  
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  
Each UART Includes  
16C550 Compatible Registers  
64-byte Transmit and Receive FIFOs  
Transmit and Receive FIFO Level Counters  
Automatic RTS/CTS or DTR/DSR Flow Control  
Automatic Xon/Xoff Software Flow Control  
RS485 Half-duplex Control with Selectable Delay  
Infrared (IrDA 1.0) Data Encoder/Decoder  
Programmable Data Rate with Prescaler  
Up to 6.25 Mbps Serial Data Rate  
Association) encoder/decoder,  
definable inputs/outputs, and  
purpose timer/counter.
