Key Concepts

Baud Rate and Data Throughput

Baud rate, often equated with bit rate in digital communications, represents the number of signal changes or symbols transmitted per second. In the context of a UART chip, this concept is essential for understanding how fast data can be sent or received, which is a primary specification of the device.

Universal Asynchronous Receiver Transmitter (UART)

A UART is a hardware communication device that converts data between parallel and serial forms for asynchronous transmission. It plays a critical role in serial communications by handling the timing and framing of data bits without a shared clock signal between devices.

Serial Communication Protocols

Serial communication protocols involve the sequential transmission of data bits over a communication channel. Understanding serial interfaces and standards, such as the common ones implemented by UART chips, is key to assessing performance parameters like speed and reliability in communication hardware.
