3.3V PCI BUS QUAD UART  
AUGUST 2003  
REV. 1.1.0  
FEATURES  
GENERAL DESCRIPTION  
High Performance Quad UART  
The XR17L1541 (L154) is a quad PCI Bus Universal  
Asynchronous Receiver and Transmitter (UART) with  
same package and pin-out as the Exar XR17C158  
octal UART. The device is designed to meet today’s  
32-bit PCI Bus and high bandwidth requirement in  
communication systems. The global interrupt source  
PCI Bus 2.2 Target Interface Compliance  
3.3 Volt PCI Bus Compliant up to 33 MHz Clock  
5 Volt Tolerant Serial Inputs  
32-bit PCI Bus Interface with EEPROM Interface  
A Global Interrupt Source Register for all 4 UARTs  
Data Transfer in Byte, Word and Double-word  
Data Read/Write Burst Operation  
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 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.  
Each UART is independently Controlled with:  
16C550 Compatible 5G (Fifth Gen) Register Set  
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  
NOTE: 1 Covered by U.S. Patents #5,649,122, #5,949,787  
Automatic RS485 Half-duplex Control Output with  
Selectable Turn-around Delay (0 to 15 bit-times)  
Infrared (IrDA 1.0) Data Encoder/Decoder  
APPLICATIONS  
Remote Access Servers  
Ethernet Network to Serial Ports  
Network Management  
Programmable Data Rate with Prescaler  
Up to 4 Mbps Serial Data Rate at 8X  
Eight Multi-Purpose Inputs/outputs  
General Purpose 16-bit Timer/Counter  
Sleep Mode with Automatic Wake-up  
Factory Automation and Process Control  
Point-of-Sale Systems  
Multi-port RS-232/RS-422/RS-485 Cards  
Same Package and Pin-out as the XR17C158,  
XR17D158, XR17C154 and XR17D154 UARTs
