Product Overview: NXP SCN2681AE1A44

The NXP SCN2681AE1A44 is a versatile dual asynchronous receiver/transmitter (DUART) integrated circuit designed to facilitate serial communication in microprocessor-based systems. This highly integrated device is ideal for applications requiring efficient serial data exchange, such as industrial control, networking, and telecommunications.

Key Features

• Dual Channel Operation: 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 separate serial lines.
• Baud Rate Generation: The SCN2681AE1A44 comes with a programmable baud rate generator capable of supporting a wide range of baud rates, making it suitable for various communication standards.
• Interrupt Handling: With its flexible interrupt handling capabilities, the DUART can manage multiple interrupt sources, improving system responsiveness and simplifying software design.
• FIFO Buffers: Each channel is equipped with a three-character receiver FIFO buffer and a one-character transmitter holding register, enhancing data throughput and reducing the risk of data overrun.
• Programmable Parity and Stop Bits: Users can configure the device to meet specific communication protocols by setting the desired parity (odd, even, or none) and the number of stop bits (1, 1.5, or 2).
• Modem Control Interface: The integrated modem control interface allows for direct connection to modem signals, streamlining hardware design and reducing external component requirements.

Applications

The SCN2681AE1A44 is suitable for a broad range of applications, including:

• Telecommunications systems
• Networking equipment
• Industrial control systems
• Point-of-sale terminals
• Computer peripheral interfaces

Additional Information

Designed for reliability and performance, the NXP SCN2681AE1A44 operates over an extended temperature range and is available in a 44-pin PLCC (Plastic Leaded Chip Carrier) package. Its compatibility with industry-standard protocols and ease of integration make it a popular choice for designers seeking a robust serial communication solution.
