The XR88C92CJ-F is a compact, multifunctional Universal Asynchronous Receiver Transmitter (UART) designed for use in embedded applications. UARTs are used to bridge the gap between an embedded system and an external communication interface such as an RS-232 bus. The XR88C92CJ-F is an enhanced version of the popular 88C92CJ-F, providing a wide range of features.

Application Fields

The XR88C92CJ-F is ideal for many embedded applications, including data transmission, industrial control, instrumentation, and medical systems. The flexible architecture and features make it suitable for multiple applications, such as in medical devices, automated industrial systems, displaying/monitoring systems, automotive ECUs, and military/aerospace systems. The UART is also suitable for short range communication between digital devices in home automation such as smart TVs, lighting, and security systems.

Working Principle

The working principle of the XR88C92CJ-F UART lies in its ability to convert serial data input into parallel data output or vice versa. This way, it is able to break down a transmission into distinct words, ensuring reliable communication between the transmitting and receiving system. The XR88C92CJ-F follows the standard synchronous UART protocol, so it is compatible with most serial communication applications. The UART also supports interrupt-driven data transfer, allowing the microprocessor to remain in an idle state while the data is being shifted.

The UART\'s FIFO (First In, First Out) buffer and data exchange unit provide smooth and efficient data transmission by buffering up to 16 words of 8-bit data. This allows devices to be connected to each other at lower frequencies, reducing the need for high-speed communication. The XR88C92CJ-F also includes a high-speed, low-power receive/transmit shift register, which allows for higher clock frequencies and improved communication performance.

The XR88C92CJ-F is fully programmable using a serial interface, allowing it to be configured to meet specific applications requirements. The UART also provides a serial interface test, allowing the user to check the communication link before the module is put into service. This guarantees reliable operation and data accuracy, eliminating costly and time-consuming troubleshooting.

The XR88C92CJ-F also includes power saving features, such as an auto/standby mode and a deep sleep mode. This minimizes power consumption, increases battery life, and reduces system heat output.

In summary, the XR88C92CJ-F is a versatile UART solution for embedded applications that require low power consumption, reliable transfer of data, and high performance. The wide range of features makes it suitable for multiple applications, from industrialcontrol and medical systems to home automation and automotive ECUs.
