This file introduces the Philips Semiconductors SCC2692 Dual Universal Asynchronous Receiver/Transmitter (DUART), a single-chip CMOS-LSI communications device that provides two full-duplex asynchronous receiver/transmitter channels in a single package.
The SCC2692 is a dual asynchronous receiver/transmitter (DUART) IC compatible with the SCN2681. It provides two full‑duplex channels, each independently programmable for data format, baud rate, and clock source. The device includes multiplexed I/O ports, a programmable 16‑bit counter/timer, and a versatile interrupt system.
The datasheet lists the pin assignments, electrical limits, timing parameters, and package options (DIP, PLCC, PQFP). It also gives ordering information, block diagrams, and detailed descriptions of the internal blocks such as the data‑bus buffer, operation control, and interrupt control.
