GENERAL DESCRIPTION  
The EXAR Dual Universal Asynchronous Receiver and  
Transmitter (DUART) is a data communications device that  
provides two fully independent full duplex asynchronous  
communication channels in a single package. The DUART  
is designed for use in microprocessor based systems and  
may be used in a polled or interrupt driven environment.  
The DUART is fabricatedusing advancedtwo layer metal,  
with a high performance density EPI/CMOS 1.8 process  
to provide high performance and low power consumption,  
and is packaged in a 40 pin PDIP, a 28 pin PDIP, and a 44  
pin PLCC.  
The XR88C681 device offers a single IC solution for the  
8080/85, 8086/88, Z80, Z8000, 68xx and 65xx  
microprocessor families.
