The IS82C50A-5Z are from a family of Universal Asynchronous Receiver Transmitter (UART), an important component of communication interfaces. A UART is responsible for controlling, sending and receiving data asynchronously between two devices, acting as a terminal for various communication standards. It enables data interchange between, for example, computers, peripherals, and communications networks. This article discusses the key operating principles of the IS82C50A-5Z and their application fields.

Working Principle of IS82C50A-5Z

The IS82C50A-5Z UART consists of a transmitter, a receiver, and a baud rate generator. The transmitter takes serial data from the host processor, encodes it and sends it along a transmission line, sending it as bits after bit. The receiver circuit takes the serial input data and converts it to parallel format which is easier to handle for the host processor. The baud rate generator, which operates in synchronous with the transmitter and receiver, sets the serial transmission data rate.

The IS82C50A-5Z has programmable data length and data format, allowing the user to set the desired number of data bits per character as well as the number of stop bits.

The IS82C50A-5Z is equipped with a transmitter and receiver that have small FIFOs (First In First Out) to suppress transmission errors. The FIFOs store up to 16 bytes of data when transmitting or receiving. This enables the UART to function effectively when handling burst transfers.

Applications of IS82C50A-5Z

The IS82C50A-5Z family of UARTs is designed for a variety of applications, including:

• Industrial Automation.
• Networking & Communications.
• Consumer Electronics.
• Computer Peripherals.
• Printers.

In industrial automation the IS82C50A-5Z is used for connecting embedded systems to installed machinery, ensuring data accuracy and reliability for plant operations. In networking and communications equipment it is used to establish communication links between computers and modems, allowing data to be sent and received. In consumer electronics and printers it is used to connect PCs to various communication ports and to allow connections between PCs and peripheral components.

The IS82C50A-5Z is also used for applications requiring reliable data transmission, such as automotive diagnostic and programming tools, cellular phones, and navigation systems.

Advantages of IS82C50A-5Z

The UART comes with several advantages, making it the preferred option for many applications. The IS82C50A-5Z offers a high-level of noise immunity and minimal current consumption, making it ideal for systems that require low power solutions.

The IS82C50A-5Z features a low receive and transmit FIFO threshold, making it less susceptible to false triggering and data accurate transmissions. Its small FIFO size allows easy implementation in applications requiring reduced latency for inter-chip data transfers.

The IS82C50A-5Z has the unique ability to detect line breaks, making it suitable for detecting break conditions in asynchronous applications. The UART also has a programmable data length and data format, allowing the user to set the desired configuration for their applications.

Conclusion

The IS82C50A-5Z family of UARTs have a wide range of applications due to their reliability and low power consumption. The UART has been designed to help meet the needs of applications with strict standard requirements, such as automotive and industrial equipment. The IS82C50A-5Z family of UARTs offer features such as FIFO size, programmable data length and data format, making them the ideal choice for many applications.
