XR17C152  
5V PCI BUS DUAL UART  
REV. 1.2.0  
JUNE 2004  
FEATURES  
GENERAL DESCRIPTION  
High Performance Dual PCI UART  
The XR17C1521 (152) is a monolithic dual PCI Bus  
Universal Asynchronous Receiver and Transmitter  
(UART) in Exar’s PCI Bus UART family. The device is  
designed to meet today’s 32-bit PCI Bus and high  
bandwidth requirement in communication systems.  
The global interrupt source register provides a com-  
plete interrupt status indication for both channels to  
speed up interrupt parsing. Each UART is indepen-  
dently controlled and has its own 16C550 compatible  
5G (Fifth Generation) register set, transmit and re-  
ceive 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, automatic half-duplex control  
output, wireless IrDA (Infrared Data Association) in-  
frared encoder/decoder, 8 multi-purpose definable in-  
puts/outputs, and a 16-bit general purpose timer/  
counter.  
PCI Bus 2.2 Target Interface Compliance  
5V PCI Bus Compliant up to 33MHz Clock  
32-bit PCI Bus Interface with EEPROM Interface  
A Global Interrupt Source Register for both 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  
Automatic RTS/CTS or DTR/DSR Flow Control  
Automatic Xon/Xoff Software Flow Control  
Automatic RS485 Half-duplex Control Output with  
16 Selectable Turn-around Delay  
Infrared (IrDA 1.0) Data Encoder/Decoder  
Programmable Data Rate with Prescaler  
NOTE: 1 Covered by U.S. Patents #5,649,122, #5,949,787  
Up to 6.25 Mbps Serial Data Rate at 5V and 8X  
APPLICATIONS  
Sampling  
Network Management  
Eight Multi-Purpose Inputs/outputs  
Factory Automation and Process Control  
Ethernet Network to Serial Ports  
Point-of-Sale Systems  
A General Purpose 16-bit Timer/Counter  
Sleep Mode with Automatic Wake-up Indicator  
Same package and pinout as the XR17D152  
(14x14x1.0mm TQFP package)  
Remote Access Servers  
Multi serial ports RS-232/RS-422/RS-485 Cards
