SCC2692AE1N28,602

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SCC2692AE1N28,602 is a dual universal asynchronous receiver/transmitter (DUART) manufactured by NXP Semiconductors. It provides two full-duplex asynchronous channels within a single chip, compatible with the SCN2681 standard. The device operates on a single +5V power supply and supports an industrial temperature range of -40°C to +85°C. It features quadruple buffered receiver data registers, programmable baud rates up to 1MB/sec, and a 16-bit counter/timer. The component is housed in a 28-pin plastic dual in-line package (DIP).

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual full-duplex asynchronous receiver/transmitters with independent channel programming.
• Quadruple buffered receiver data register to minimize overrun potential.
• Programmable data format supporting 5 to 8 data bits plus parity and variable stop bits.
• Integrated 16-bit programmable counter/timer for baud rate generation.
