UARTs (Universal Asynchronous Receiver Transmitter) Overview

The NXP USA Inc. SCC2681AE1A44,512 is a Dual Universal Asynchronous Receiver/Transmitter (DUART) manufactured in a CMOS process. It provides two independent full-duplex asynchronous receiver/transmitter channels within a single package. The device interfaces directly with microprocessors and supports both polled and interrupt-driven systems. Each channel features independently programmable operating modes and data formats. The receiver utilizes quadruple buffering to minimize over-run potential and reduce interrupt overhead. Baud rates are selectable from eighteen fixed options ranging from 50 to 115.2 k baud, or via external clock inputs.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

Dual full-duplex asynchronous receiver/transmitter channels
Quadruple buffered receiver data registers
Programmable data format including parity and stop bits
Versatile interrupt system with maskable conditions

UARTs (Universal Asynchronous Receiver Transmitter) Applications

Clustered terminal systems requiring dual-speed channels
Microprocessor-based serial communication interfaces
Interrupt-driven embedded serial I/O systems

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm that the component meets RoHS compliance requirements for your target application. Ensure compatibility with existing PCB footprints for the PLCC44 package before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UART channels are required on a single chip. Consider the PLCC44 package availability if surface mount assembly is preferred. Verify that the industrial temperature range (-40 °C to +85 °C) aligns with environmental constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SCC2681 family of dual asynchronous receiver/transmitters. It serves as a direct replacement for older SCN2681 devices. The family includes variants with different packages such as DIP28 and DIP40, offering flexibility for various board layout requirements.
