The National Instruments PCI-7813 is a high-performance Digital Reconfigurable I/O Device designed for versatility in various applications requiring custom decision-making at hardware-timed reliability and accuracy. This device features an integrated 3M Gate Virtex-II V3000 FPGA, providing the capability to configure digital lines as timers, counters, I/Os, PWM, or encoder inputs. With 160 digital I/Os, the PCI-7813 incorporates 28,672 flip-flops, 28,672 4-input LUTs, 96 multipliers (18 x 18), and 1,728 Kbits of embedded block RAM, allowing for extensive processing capabilities. Users can specify the power-up state of any digital I/O channel. The device also includes an onboard clock with selectable timebase options of 40, 80, 120, 160, or 200 MHz, facilitating precise timing for applications. The digital lines are TTL compatible and support 3.3 V logic levels, ensuring broad integration potential. The PCI-7813 is designed for operation in standard PCI expansion slots in Windows-based host machines, drawing 850 mA at +3.3 VDC and 9 mA at +5 VDC under typical conditions. With an operating temperature range of 0 °C to 55 °C, this RIO device is ideally suited for a range of industrial automation tasks. Although the PCI-7813 has been designated as a mature product by National Instruments, it remains available for purchase and repair through Apex Waves.
