UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SCC2681TC1A44,512 is a dual asynchronous receiver/transmitter (DUART) manufactured by NXP Semiconductors. It provides two independent full-duplex channels in a single package. The device operates on a single +5 V power supply within a commercial temperature range of 0 °C to +70 °C. It features quadruple buffered receiver data registers and supports baud rates up to 115.2 kbaud or non-standard rates derived from its programmable counter/timer. Maximum data transfer rates reach 1 MB/sec at 1× clock speeds. The component utilizes a 44-pin Plastic Lead Chip Carrier (PLCC) package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

Fast bus cycle times reduce or eliminate CPU wait states
Quadruple buffered receiver data registers minimize over-run potential
Programmable baud rate selection including fixed rates and external clocks
Multi-function programmable 7-bit input and 8-bit output ports

UARTs (Universal Asynchronous Receiver Transmitter) Applications

Polled or interrupt-driven microprocessor systems
Clustered terminal systems requiring dual-speed channel applications
I/O intensive embedded systems

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix for the PLCC-44 package configuration. Confirm that the operating voltage requirements align with the +5 V ± 10% specification. Ensure the design accommodates the commercial temperature range limits. Check for any RoHS compliance documentation if required for the target assembly process.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when fast bus cycle times are necessary to interface directly with high-speed CPUs without wait states. Consider the quadruple buffering feature for reducing interrupt overhead in complex systems. Evaluate the availability of the 44-pin PLCC package against board layout constraints. Verify compatibility with the required baud rate generation methods.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SCC2681T family of dual universal asynchronous receiver/transmitters. It is an evolution of standard DUART designs, optimized for faster bus operations. The device integrates two complete UART channels along with a counter/timer and general-purpose I/O ports into a single CMOS LSI chip.
