Universal Asynchronous Receiever Transmitter (UARTs) are the least complex type of interface devices used to convert digital transmissions between the twomost common communication protocols, asynchronousand synchronous. UARTs are divided into two categories; One is full-duplex andthe other is half-duplex.

The full-duplex UART is capable of communicating on two lines where each line is independently receiving and transmitting. It is mainly used for point-to-point connections. The half-duplex UARTallows for only one direction at a time, it is mainly used for broadcasting or when data traffic is unidirectional.

The SC16C852 UART Lite is a full-duplex UART manufactured by Semiconductor Components Industries, LLC. The SC16C852 UART is based on the System on Chip (SoC) design. It is composed of a controller and transceiver integrated in a single package. The SC16C852UART supports a wide range of communication speeds, from 1200 bauds to 230.4 kbps.

The SC16C852 UART works as both a transmitter and receiver. In transmitter mode, the UART sends data to a receiving device over a wire using the UART protocol. The signal is transmitted to the receiver using a logic 1 in the high byte. In receiver mode, the signal is transferred by the receiver and relayed back to the transmitter by logic 0 in the high byte.

The SC16C852 UART is commonly used in various applications such as industrial network controllers, medical instruments, power equipment, POS systems, and robotic applications. Its features and low-voltage operation make it ideal for a wide range of embedded applications with stringent power requirements.

The primary benefit of the SC16C852 UART is its power efficiency. It has seven power modes ranging from 10 mW to 300 mW, allowing it to adjust its power consumption to the application\'s requirements. Additionally, its low-voltage operation reduces the device\'s operating temperature, allowing it to operate in high-temperature applications. This makes it ideal for automotive and industrial applications.

In addition to power efficiency, the SC16C852 UART has two additional benefits that make it a preferred choice in embedded applications. It is fully compatible with the latest standards, including both 3.3V and 5.0V devices. Additionally, it has a small footprint, making it suitable for applications with limited space. Furthermore, it offers an enhanced performance thanks to its programmable data path, which allows for optimizing the transmission data rate.

The working principle of SC16C852 UART is simple. Whenever data is sent, the UART transfers it in the form of serial signals. The signal is converted from parallel to serial by a UART circuit. This converter takes the data in parallel, converts it into serial by adding start and stop bits before and after each character, and then transmits it to the receiver. On the receiver side, the serial signals are received by the UART and converted back to the original parallel data.

In summary, the SC16C852 UART is a robust and power-efficient solution for a wide range of embedded applications. Its main advantages include low-voltage operation and compatibility with both 3.3V and 5.0V devices. Additionally, it has a small footprint, allowing it to be used in applications with limited space. Its easy-to-use and programmable data path makes it an ideal choice for applications in the automotive, industrial, and medical fields.
