SCC2691AE1A28,518

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SCC2691AE1A28,518 is a single-chip CMOS Universal Asynchronous Receiver/Transmitter (UART) fabricated using Philips Semiconductors technology. It provides full-duplex asynchronous communication with an operating speed selectable from 22 fixed baud rates ranging from 50 to 115.2K baud, non-standard rates up to 115.2 kb/s derived from a programmable timer, or external 1X/16X clocks. The device features a quadruple buffered receiver data register and operates from a single +5V power supply. It supports commercial temperature ranges of 0°C to +70°C and industrial ranges of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

Full-duplex asynchronous receiver/transmitter with independent receiver and transmitter clock selection
Quadruple buffered receiver data register to minimize overrun potential and reduce interrupt overhead
Programmable data format supporting 5 to 8 data bits plus parity and 1, 1.5, or 2 stop bits
On-chip crystal oscillator and 16-bit programmable counter/timer for flexible timing generation

UARTs (Universal Asynchronous Receiver Transmitter) Applications

Clustered terminal systems requiring dual-speed channel applications
Interrupt-driven serial communication systems
Multi-processor communications utilizing address frame recognition

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against current NXP documentation to confirm package type and temperature grade. Confirm availability status as older revisions may be discontinued. Ensure compatibility with existing system voltage requirements and interface protocols before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a TTL-compatible UART with independent baud rate control for receiver and transmitter channels is required. Consider the quadruple buffering feature for high-throughput interrupt-driven environments. Verify that the available packages match the PCB layout constraints and thermal requirements of the target application.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SCC2691 family of universal asynchronous receiver/transmitters originally developed by Philips Semiconductors. The family includes variants such as the SCC2691AC1N24 and SCC2691AE1N24, differing primarily in package style and operating temperature range specifications.
