SCC2698BC1A84,512

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SCC2698BC1A84,512 is an enhanced octal universal asynchronous receiver/transmitter (Octal UART) manufactured by NXP USA Inc. It integrates eight full-duplex asynchronous channels within a single package using CMOS technology. The device supports independent baud rate selection for each channel from 26 fixed rates ranging from 50 to 38.4K baud, non-standard rates up to 115.2K baud, or user-defined rates via programmable counter/timers. It features quadruple buffered receiver data registers and operates on a single +5V power supply with TTL compatibility.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates eight independent full-duplex asynchronous receiver/transmitter channels in a single package
• Provides quadruple buffered receiver data registers to minimize overrun potential and reduce interrupt overhead
• Supports programmable data formats including 5 to 8 data bits, parity options, and 1, 1.5, or 2 stop bits
• Includes four multi-function programmable 16-bit counter/timers for generating miscellaneous clocks or timeout periods

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Clustered terminal systems requiring dual-speed channel applications
• High-density serial communication interfaces utilizing multiple asynchronous channels
• Systems requiring independent baud rate generation for individual receiver and transmitter paths

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure that the PLCC package variant matches the design requirements. Confirm RoHS compliance status through official datasheets prior to procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when eight independent asynchronous channels are required within a single integrated circuit. Consider the availability of internal baud rate generators and programmable counter/timers for flexible clocking needs. Evaluate the need for quadruple buffering to manage high-throughput interrupt-driven environments effectively.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SCC2698B family of enhanced Octal UARTs. It serves as an upwardly compatible version of the 2698A model, offering additional status outputs on multipurpose I/O pins. The device is designed for applications demanding high integration density and low power consumption in serial communication architectures.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

SCC2698BC1A84 is functionally compatible with the standard SCC2698BC1A84 commercial grade variant. Verify pinout and register compatibility if substituting with older 2698A models.
