The SCN68681C1N40 is a versatile integrated circuit designed by NXP Semiconductors, renowned for its high-performance and reliability in serial communication applications. This Dual Universal Asynchronous Receiver/Transmitter (DUART) is an essential component for systems that require efficient and simultaneous serial data exchange through multiple channels.

Key Features

• Integrated Dual Channel: The device features two independent full-duplex channels, each with its own set of registers and controls. This allows for simultaneous transmission and reception of data on two different serial ports.
• Programmable Baud Rate: Each channel supports a wide range of baud rates, which can be programmed to meet various communication requirements, ensuring compatibility with a broad spectrum of serial devices.
• Flexible Character Length: The DUART supports 5, 6, 7, or 8-bit character lengths, allowing it to adapt to different data formats and protocols.
• Parity and Error Detection: It offers even, odd, or no-parity bit generation and detection, along with error detection capabilities such as framing error, overrun error, and parity error detection.
• On-Chip Status Registers: The device includes status registers for each channel, which provide real-time information about the state of the receiver and transmitter, aiding in error handling and flow control.
• Modem Control Interface: The SCN68681C1N40 is equipped with a modem control interface, which includes signals such as Request to Send (RTS) and Clear to Send (CTS), enabling hardware flow control for modem applications.

Applications

This DUART is ideal for a wide range of applications in the computing, telecommunications, and industrial sectors. It is especially well-suited for:

• Serial communication in microprocessor-based systems
• Network servers and telecommunications equipment
• Industrial control and factory automation systems
• Point of Sale (POS) terminals
