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 XR88C681 device offers a single IC solution for the
8080/85, 8086/88, Z80, Z8000, 68xx and 65xx
microprocessor families.
The DUART is fabricated using advanced two 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.
