It also includes an integrated I2C bus master/slave, a parallel port, and a JTAG emulation port. This makes the chip suitable for many applications that require a highly integrated solution.

Working Principle of XR17V258IVTR-F

The XR17V258IVTR-F is a highly integrated UART chip that supports four independent UART channels, up to 8 Mbps baud rates, and various data formats. It is constructed with an on-chip Exar SxR1703 MultiSync UART core, advanced power management and high-bandwidth 1-lane or 2-lane PCI Express interfaces.

The core of the chip is the Exar SxR1703 MultiSync UART core which provides the UART interface for data transmission between two devices. In this standard configuration, the chip supports up to 8 Mbps baud rates in asynchronous operation, full-duplex as well as half-duplex operation and a variety of data formats. It also contains advanced power management features that can be used to maintain low power consumption in idle or sleep modes.

The core of the chip is further enhanced by an internal I2C bus master/slave, a parallel port, and a JTAG emulation port. These ports enable the chip to support a variety of communications and control functions. The parallel port is used to connect peripherals and the JTAG interface allows for the in-circuit debugging of programs.

The XR17V258IVTR-F is used in a variety of application fields due to its advanced features, flexibility and low power consumption. In addition to its wide range of features and low power consumption, the chip is highly integrated and cost-effective. providing an excellent solution for embedded control and communication systems.
