Introduction to UART

Universal Asynchronous Receiver Transmitter (UART) is a hardware component used to send and receive information using a serial communication protocol. The UART interface is one of the most commonly used serial protocols in embedded systems, providing a low-cost and simple digital data communication interface between multiple devices. UART provides asynchronous communication, meaning no external clock signal is required. The SCC2692AE1B44,551 is a UART component that allows serial data transmission and reception over two-wire and four-wire serial interfaces.

SCC2692AE1B44,551 Overview

The SCC2692AE1B44,551 is a single-channel UART designed for low voltage and low power applications, such as point-of-sales (POS) terminals, barcode scanners, printers, medical instrumentation, and other automated data collection and transmission systems. The device supports asynchronous communication up to 115.2kbps at a range of data rates from 4,800bps – 115,200bps, as well as full-duplex communication over a four-wire interface. It includes both 2-wire and 4-wire serial interfaces, receive data buffer, and auto-baud rate detection.

Application Field and Working Principle

The SCC2692AE1B44,551 is commonly used in industrial automation applications, where a system requires accurate and reliable transmission of digital data over long distances. Examples include barcode scanner, RFID tag readers, and building automation systems. The features of the UART device make it ideal for such applications due to its low power consumption, fast speed, and high communication reliability. The device receives data from the communication interface, and then sends it to the receiving UART via the internal data buffer. The data is transmitted to the receiving UART asynchronously, meaning it is sent in a continuous stream without any external clock signal. The receiver then reads the data from the buffer, processes it, and transmits the appropriate response.The SCC2692AE1B44,551 device is designed for low-voltage operation for a wide range of operating conditions. The UART supports serial communication rates up to 115.2 kbps and a wide range of baud rates. It also features auto-baud rate detection, where the device can detect the baud rate used in the communication system and adjust to it without the need to configure it first. This provides flexibility in applications as it can support a wide range of communication configurations.

Conclusion

In conclusion, the SCC2692AE1B44,551 is a UART designed for use in low-voltage, low-power applications. It provides full-duplex serial data transfer and can support data rates up to 115.2 kbps. The UART also features auto-baud rate detection, enabling it to adapt to the communication environment without manual configuration. It is commonly used in industrial automation, barcode scan systems, and other automated data collection and transmission systems due to its low power consumption, high communication reliability and fast speed.
