Universal Asynchronous Receiver Transmitter (UART) is a type of serial communication interface that is widely used in electronic devices. It is a simple and reliable way to transmit data between devices, and it is commonly used in microcontrollers, computers, and other electronic devices. UARTs are available in different models, and each model has its own set of features and specifications. In this article, we will discuss the differences between mainstream Interface - UARTs models.
UART Basics
Before we dive into the differences between UART models, let's first understand the basics of UART. UART is a type of serial communication interface that uses two wires to transmit data between devices. These wires are known as the TX (transmit) and RX (receive) lines. The TX line is used to transmit data from the sender to the receiver, while the RX line is used to receive data from the receiver.
UART uses a protocol known as asynchronous serial communication. In this protocol, data is transmitted in a series of bits, and each bit is transmitted one at a time. The sender and receiver must agree on the baud rate, which is the speed at which the data is transmitted. The baud rate is measured in bits per second (bps).
UARTs are available in different models, and each model has its own set of features and specifications. The following are the differences between mainstream Interface - UARTs models.
1. Standard UART
The standard UART is the most basic type of UART. It is a simple and reliable way to transmit data between devices. The standard UART supports data rates up to 115,200 bps, and it uses a 8-bit data frame with no parity bit. The standard UART is commonly used in microcontrollers and other embedded systems.
2. Enhanced UART
The enhanced UART is an improved version of the standard UART. It supports higher data rates up to 1 Mbps, and it uses a 9-bit data frame with parity bit. The enhanced UART also supports hardware flow control, which allows the sender and receiver to control the flow of data. The enhanced UART is commonly used in high-speed communication applications.
3. UART with FIFO
The UART with FIFO (First-In-First-Out) is a type of UART that includes a buffer to store incoming and outgoing data. The FIFO buffer allows the UART to handle bursts of data more efficiently, and it reduces the risk of data loss. The UART with FIFO supports data rates up to 1 Mbps, and it uses a 8-bit data frame with no parity bit. The UART with FIFO is commonly used in applications that require high-speed data transfer.
4. IrDA UART
The IrDA (Infrared Data Association) UART is a type of UART that uses infrared light to transmit data between devices. The IrDA UART supports data rates up to 115,200 bps, and it uses a 8-bit data frame with no parity bit. The IrDA UART is commonly used in applications that require wireless communication, such as remote controls and mobile devices.
5. LIN UART
The LIN (Local Interconnect Network) UART is a type of UART that is designed for automotive applications. It supports data rates up to 20 kbps, and it uses a 8-bit data frame with no parity bit. The LIN UART also supports a checksum to ensure data integrity. The LIN UART is commonly used in automotive applications, such as in-vehicle networking and diagnostics.
6. Smart Card UART
The Smart Card UART is a type of UART that is designed for smart card applications. It supports data rates up to 115,200 bps, and it uses a 8-bit data frame with no parity bit. The Smart Card UART also supports a protocol known as T=0, which is used for communication with smart cards. The Smart Card UART is commonly used in applications that require secure communication, such as banking and identification.
Conclusion
UART is a simple and reliable way to transmit data between devices. UARTs are available in different models, and each model has its own set of features and specifications. The differences between mainstream Interface - UARTs models include data rates, data frame size, parity bit, flow control, buffer size, and application-specific features. When selecting a UART for a specific application, it is important to consider the requirements of the application and choose a UART that meets those requirements.
