Description
The Part Number 192463C-01 identifies a specific PC-based R Series model, the PCI-7811, which falls under the category of PC-based R Series. This model, known as the NI PCI-7811R, is characterized by its 1M Gate Digital RIO, capable of handling 160 Digital I/O (DIO) channels.
At the heart of the PCI-7811 is a 1M Gate Virtex-II FPGA, which provides substantial flexibility and power for processing and custom logic applications. It features 10,240 flip-flops, allowing for intricate timing and control operations. Furthermore, the inclusion of 4-input LUTs (Look-Up Tables) enhances the FPGA’s ability to perform complex logical functions.
For applications requiring arithmetic operations, the PCI-7811 is equipped with 40 18×18 multipliers, making it well-suited for digital signal processing tasks. Additionally, it offers 720 Kbits of encoded Block RAM, providing ample storage for data and instructions within the FPGA.
This model boasts 160 TTL compatible Digital I/O Channels, offering a wide range of input/output possibilities. Each channel is designed to source or sink 4.0 mA of current, with short-circuit protection on all output lines for up to eight lines simultaneously, ensuring the device’s safety and reliability.
The PCI-7811 has a current consumption of approximately 650 mA, which is typical for devices of its capabilities. Connectivity is facilitated by four 68-pin, VHDCI high-density female connectors, providing robust and reliable connections to other devices and systems.
This device can operate as either a Master or Slave in a PCI expansion slot, offering flexibility in system integration. It supports three DMA channels for efficient data transfers, alongside various data transfer modes including interrupts, DMA, and Programmed I/O. An onboard clock is provided for timing-sensitive applications.
