National Instruments 783763-01 Controller for FlexRIO

Part Number 783763-01 is the identifying part number for the National Instruments NI-7931 Controller for FlexRIO. The 783763-01 ships with a Xilinx Zynq-7020, XC7Z020 All Programmable SoC which features an ARM Cortex-A9-based dual-core processor with a speed of 667 MHz. Likewise, it features 512 MB of DDR3 RAM and 512 MB of nonvolatile memory, based on SLC NAND flash. The real-time clock accuracy is 5 ppm while the flash reboot endurance is 100000 cycles. The device comes with the NI Linux Real-Time (32-bit) operating system. Furthermore, the CMOS battery on the device has a battery life of 10 years with power applied to the power connector or in storage up to 70 °C. 

The internal reference clock on the 783763-01 has a VCXO-type oscillator with a frequency of 100 MHz. Likewise, it has a single Ethernet port that is compatible with IEEE 802.3 and supports the 10Base-T, 100Base-TX, and 1000Base-T Ethernet interfaces. The communication rates are auto-negotiated between 10 Mbps, 100 Mbps, and 1000 Mbps and run in both full and half-duplex mode. The maximum cabling distance is 100 m per segment. Furthermore, there is a single USB device and host port using the USB 2.0 Hi-Speed interface that has a maximum data rate of 480 Mb per port. Moreover, the SD card slot supports SD and SDHC standards and memory sizes up to 32 GB. 

The 783763-01 also features a Kintex-7 XC7K325T reconfigurable FPGA that has 203800 LUTs, 840 DSP48 slices, and an embedded block RAM of 16020 kbits. The default timebase is 40 MHz while the timebase accuracy is ±100 ppm. There are 16 DMA channels and data transfers take place through DMA, interrupts, and programmed I/O. 136 general-purpose channels in the FPGA digital I/O can be configured as 136 single-ended, 68 differential channels, or a combination of both. This controller supports an input voltage of 9 V to 30 V and consumes a maximum power of 60 W. The recommended power supply for the device is >75 W, 12 VDC. The device measures  9.21 in. × 5.14 in. × 1.73 in. in physical dimensions and weighs 1170 g.
