Introduction:
UART and USART are both communication protocols commonly used in computer science and engineering. While they share many similarities, there are also key differences between the two. This article will explain the difference between UART and USART communication.
UART (Universal Asynchronous Receiver-Transmitter):
UART is a communication protocol that uses asynchronous means of communication. It is commonly used for serial communication between devices. The UART protocol involves the transmission of data one bit at a time, without the use of a clock signal. Instead, the data is transmitted with start and stop bits to indicate the beginning and end of each data frame.
USART (Universal Synchronous/Asynchronous Receiver-Transmitter):
USART, on the other hand, is a more advanced communication protocol that supports both synchronous and asynchronous means of communication. This means that it can transmit data using either a clock signal (synchronous) or start/stop bits (asynchronous). USART is often used in applications that require higher data rates or more precise timing.
Difference between UART and USART:
The main difference between UART and USART lies in their communication capabilities. Here are the key differences:
1. Asynchronous vs. Synchronous Communication:
- UART: UART only supports asynchronous communication. It transmits data using start and stop bits without the use of a clock signal.
- USART: USART supports both asynchronous and synchronous communication. It can transmit data using start/stop bits or synchronize the transmission with a clock signal.
2. Clock Signal:
- UART: UART does not require a clock signal for data transmission.
- USART: USART can utilize a clock signal for data transmission in synchronous mode.
3. Flexibility:
- UART: UART is simpler and more straightforward, making it easier to implement in many applications.
- USART: USART is more versatile and can be used in a wider range of applications due to its support for both asynchronous and synchronous communication.
4. Data Rate:
- UART: UART is generally used for lower data rates.
- USART: USART is capable of higher data rates, making it suitable for applications that require faster transmission speeds.
Conclusion:
In summary, UART and USART are communication protocols used for serial data transmission. The main difference between the two lies in their communication capabilities. UART only supports asynchronous communication, while USART supports both asynchronous and synchronous communication. USART is more versatile and can handle higher data rates, but it is also more complex to implement compared to UART.
