The XR17V258IV-F family is the newest addition to Exar’s highly acclaimed line of high-speed serial interface components. This family of interface components offers a versatile, low power, and cost-effective solution for system designers to implement high-speed serial connectivity in their applications. It is optimized for use in data communications applications as well as in a variety of industrial automation and medical applications.

The XR17V258IV-F is a member of the Universal Asynchronous Receiver Transmitter (UART) family of interface components and is optimized for applications with data rates up to 8 Mbps. The device features a transmitter with two independent transmission buffers and a receiver with two separate receive FIFOs, allowing data transfer at maximum speed with minimal processor overhead. It also supports several data formats such as 9-bit, 8-bit, 7-bit and 6-bit modes. A hardware flow control feature is also available to enable data flow control, with either RTS/CTS or XON/XOFF protocols, allowing integration into an array of application environments.

The XR17V258IV-F is designed to provide maximum performance and flexibility for a wide array of system designs. It supports the use of four different clocking frequencies (1 MHz, 1.5 MHz, 2 MHz, and 4 MHz). This allows the system designer to select the best possible clock speed based on the desired transfer rate, while keeping power consumption and system cost at a minimum. The device also supports a large number of hardware flow control options and numerous settings that enable the designer to optimize their system for maximum performance and flexibility.

The working principles of the XR17V258IV-F are quite straightforward. This device provides two independent transmitters and receivers, each with its own FIFO buffer for increased data transfer speeds. It supports a variety of clocking frequencies and settings, as well as hardware flow control protocols and other configurations. Once configured, the device will transmit and receive data in the specified format, allowing for reliable and efficient data transfers.

The XR17V258IV-F is ideally suited for a variety of data communications and industrial automation applications, including automotive, medical systems, radio-frequency identification (RFID), cell phones, and data logging systems, just to name a few. Its ability to handle high data rates, low power consumption, and accurate data transfers makes it the ideal choice for a wide range of applications. Its combination of features and performance make it an excellent solution for implementing high-speed serial connectivity in any system.
