Xilinx\'s XC7VX690T-2FFG1926C is an FPGA device designed for general embedded computing applications. It is a high performance and low power programmable logic device, offering a wide range of features, from DDR3 and QDRII/II+ support, to up to 32Mbits of block RAM and up to 14.1Mbits of distributed RAM. The device also supports higher speed transceivers for fast, low latency data communications, and multi-channel DMA for efficient data transfers between the FPGA and system memory.

FPGAs, or Field Programmable Gate Arrays, are logic devices which allow for flexible designs by providing the capability to be configured and re-programmed for different functions. This unique advantage of the FPGAs makes them highly suitable for a wide range of embedded applications. For instance, FPGAs can be used for image processing, automation, robotics and other applications that require a large amount of customization. Since FPGAs are more compact and require less power than traditional processors, they also provide greater flexibility than microprocessors in terms of performance and design.

Another advantage of the XC7VX690T-2FFG1926C is its programmability. It can be configured and re-programmed in hardware design, changing its functionality using VHDL or Verilog. By using programmable logic and combinational elements, the FPGA can be tailored to meet specific application requirements. This feature allows for high flexibility, especially for large projects where multiple devices are required and each device has to perform specialized tasks.

The working principle of the XC7VX690T-2FFG1926C is very simple. It has two main components, the base fabric and the Programmable Logic (PL). The base fabric is a predefined logic element and the PL is used to allocate logic elements and their functions. Logic elements such as look-up tables (LUTs) and registers are allocated to the PL, allowing a user to design the logic they need. The FPGA then uses the logic that is defined by the configuration to perform its tasks.

Once the FPGA device is programmed, it can then control and monitor the I/O peripherals of the system. I/O peripherals like LEDs and switches can be interfaced with the FPGA using a peripheral bus, such as an AXI, AXI4, or Hyperbus. The AXI and Hyperbus allow the FPGA to communicate with the I/O peripherals so that it can control them.

The XC7VX690T-2FFG1926C is also capable of being interfaced with system-level control systems. This includes support for communication interfaces such as Ethernet, Serial and JTAG. These interfaces allow for communication between the FPGA and other devices on the network, such as a controlling computer. Such communication also allows the FPGA to control large and complex systems, like factory automation, remotely.

In conclusion, the XC7VX690T-2FFG1926C is an FPGA device designed for general embedded applications. It offers high performance, low power consumption, customizable logic, and support for a wide range of communication interfaces. Its programmable logic makes it highly suitable for a variety of embedded applications, from image processing to factory automation. The FPGA can be used to monitor and control system peripherals and other devices on a network, making it a valuable tool for a wide range of purposes.
