16550 UARTs specifications
The Lava Computer 16550 UART, short for Universal Asynchronous Receiver-Transmitter, is a highly efficient serial communication device designed to facilitate the transfer of data between a computer and peripheral devices. The 16550 UART has become a standard in the industry due to its advanced features and capabilities that enhance data transmission performance and reliability.One of the standout characteristics of the 16550 is its built-in 16-byte FIFO (First In, First Out) buffer. This feature allows for the storage of multiple data bytes before they are sent to or received from the CPU. The FIFO buffer significantly reduces the chances of data overflow, especially during high-speed data transfers, making it more efficient than its predecessor, the 16450 UART, which lacked this capability. By buffering data, the 16550 UART ensures that the CPU can process data more effectively without losing information during busy periods.
Moreover, the 16550 UART supports higher baud rates compared to earlier UART models. With support for speeds up to 115,200 baud, the 16550 becomes an ideal choice for applications requiring high-speed serial communications, such as modem connections, point-of-sale systems, and industrial automation. Additionally, it offers compatibility with various protocols used in communication, further enhancing its flexibility.
The 16550 UART also includes programmable line control features, allowing users to configure data bits, stop bits, parity, and flow control settings. This programmability grants users the ability to tailor the communication parameters to suit specific application requirements, ensuring optimal performance in diverse scenarios.
Another significant advancement in the 16550 UART is its interrupt handling capabilities. The device can generate interrupts for several events, such as the reception of data or the completion of transmission. This feature is critical for real-time applications as it allows the CPU to respond promptly to incoming data, thus improving overall system responsiveness.
In conclusion, the Lava Computer 16550 UART is a robust and versatile component that has become an essential building block in the world of serial communication. With its 16-byte FIFO buffer, high-speed support, programmable configurations, and efficient interrupt management, it stands out in various applications, enabling seamless and reliable data exchange between computers and devices. As technology continues to advance, the 16550 UART remains a relevant and crucial piece in ensuring efficient communication in modern systems.
