INTEGRATED CIRCUITS SCC68681 Dual asynchronous receiver/transmitter (DUART) Product data 2004 Apr 06 Philips Semiconductors Philips Semiconductors Product data Dual asynchronous receiver/transmitter (DUART) SCC68681 DESCRIPTION The Philips Semiconductors SCC68681 Dual Universal Asynchronous Receiver/Transmitter (DUART) is a single-chip MOS-LSI communications device that provides two independent full-duplex asynchronous receiver/transmitter channels in a single package. It is compatible with other S68000 family devices, and can also interface easily with other microprocessors. The DUART can be used in polled or interrupt driven systems. It is manufactured in a CMOS process. The operating mode and data format of each channel can be programmed independently.
